1、动态系统开发方法探析

Introduction

Information systems modifications and routine enhancements is one of the most significant changes that could affects organizations productivity and performances in delivering high quality products and services, many organizations are concerned with problems of running applications that have been in operations for several years, these types of systems are known as the legacy types, a critical point .html in many of such old systems arrives when

I. High maintenance costs is been incurred.

II. Use of obsolete hardware and software resulting in loss of profit and decline productivity.

III. Improper documentations and lack of user support with the knowledge required to maintain such systems.

IV. Systems becoming problematic and incapable of handling requirement for change in the business environment.

All these factors combined results in the need to carry out overall changes in current systems used by most organizations. Some companies prefer to replace legacy systems with new ones, to achieve their objectives, however this may sometimes be expensive, therefore modifying existing ones is always a good choice. As Warren (1999) stated, ‘if you abandon a legacy system, you face a risk of losing vital businesses knowledge which is embedded in many old system’, (Warren, I.1999, p.120). If organizations eventually choose to continue maintaining the existing system, consideration should be given to implementing new features that will make the system more effective and efficient in accommodating changes in tasks and the business rules, also the system should incorporate new functional requirements and that the existing problems are corrected.

This report has been prepared as recommendations of an appropriate information system development methodology ISDM for quality Kitchen Company; it summarizes DSDM as an appropriate method and explains reasons with various issues to consider by the IT manager of quality kitchen in choosing this method.

2、系统发展探究

Introduction:

System developments can be done in several different ways, among these different approaches, two methodologies are especially important as they work as the fundamental system development approaches today. They are: traditional structured approach and object oriented Approach.

Traditional structured approach which was developed in 1970s became the dominant system development methodology in 1980s. However with the growing complexities of information system, the traditional approach has shown less competent in modern system development.

Since traditional structured approach has shown the inherit shortages when dealing with complex systems, which is the main trend of the current system. A new system developing method was introduced to better cope with the new system developing environment, that’s the object-oriented approach.

The following sections will provide a basic introduction of these two methodologies, compare their advantages and disadvantages. And finally a short discuss about the risks might involved in transition from traditional structured approach to object oriented approach

3、人机交互分析

Introduction

Nowadays, everyone is using software application to perform their tasks. Software application is being utilized in everywhere, be it in the public, within a particular organization or at home.

There is a study named human-computer interaction (HCI). This study is very important to enhance the effectiveness of a software application. It is a study of the interaction of humans with computers and to what level that computers are or are not developed for successful interaction with human beings. HCI tries to ensure that the interaction between human and computer are successful. Interaction between users and computers happens at the user interface, which include both software and hardware.

My final year project, Timetable Management System, requires a lot of interaction between user and the system. It is mainly because it requires many data from the user to generate the timetable or reports. Hence, in this seminar, discussions on a few important aspects will be included. Some brief overviews on the contents are such as introduction to HCI, importance of HCI, issues in HCI, theories and principles of HCI and types of User Interface. The main ideas of the contents are adapted from the book “Human-Computer Interaction” by Alan Dix, Janet Finlay and etc, published by Pearson Prentice Hall. Another main reference is “The Essence of Human-Computer Interaction” by Christine Faulkner which is published by Pearson Prentice Hall too.

4、库存管理系统的开发研究

Paper代写：The impact of fintech on the innovation and development of commercial Banks

下面为大家整理一篇优秀的paper代写范文- The impact of fintech on the innovation and development of commercial Banks，供大家参考学习，这篇论文讨论了金融科技对商业银行创新发展的影响。金融科技是一种新型的金融方式，一种新兴的技术，可以通过使用各类的过程或者产品，对金融市场进行调控的技术。金融科技技术的出现改变了传统的金融模式，首先是对商业银行的产品创新。现阶段，商业银行新推出了网上产品，产品趋向于虚拟化，这类产品的出现方便了有关的操作，用户可以直接在第三方平台上进行操作，节省了银行员工的工作流程，提升了用户的商业体验，在一定程度上推动了金融领域的进步。另外，金融科技对商业银行的服务也有一定的创新。金融科技产品的出现，使得银行用户可以直接在网络上进行业务的办理，银行员工为客户提供在线服务，节省了双方的时间，大大的提升了工作的效率，提升了商业银行的服务质量。

In recent years, China's economic level has shown a trend of rapid development. The continuous improvement of Internet technology has promoted the development of all walks of life in China to some extent. The integration of finance and science and technology indicates that China's financial industry has entered a stage of rapid development. At present, the development of commercial Banks has attracted more and more people's attention. According to relevant data, China's financial technology is mainly based on third-party platform payment and P2P, and alipay has become one of China's four new inventions, which facilitates people's life. This article mainly takes the development of fintech as the entry point to discuss the impact of fintech on the development of commercial Banks, hoping to attract people's attention and solve the troubles of relevant personnel.

Financial science and technology development to a certain extent, the convenient people's life, the rapid development of the financial products to promote the progress of the industry of our country economy, our third-party payment, for example, at present, most of the cities and areas in China began to implement the WeChat or pay treasure payment, the payment of a has facilitated people's lives, to a certain extent promoted the industry of our country economy and the development of science and technology industry. Next, we discuss the development of commercial Banks.

Fintech is a new type of finance. Through investigation of relevant materials, we can know that at present, fintech means an emerging technology that can regulate the financial market through the use of various processes or products. The development of this technology has attracted extensive attention since it emerged. This technology first appeared in the United States, which developed its economy through market regulation and improved its economic system. In recent years, Chinese government or relevant departments have paid more attention to the technology of fintech and developed various fintech products, the main products of which are third-party system and taobao. Fintech products cover a wide range of fields, not only financial products, but also artificial intelligence products and cloud computing.

The emergence of financial technology changed the traditional mode of financial, can say, the emergence of financial technology open another door of the financial industry, financial technology compared with traditional financial technology has more advantages, for example, information is abundant, the transaction is more convenient, in addition, the financial technology also has strong secrecy performance and safety performance, the development of financial industry in China has a certain role in promoting.

Based on the analysis of relevant data, we can know that at present, the application of fintech has a certain impact on the innovation of commercial Banks. Next, we analyze it from two aspects:

The first is the product innovation of commercial Banks. Through the analysis of relevant materials, we can know that the products of traditional commercial Banks mainly have three types, namely core products, basic products and extension products. These three kinds of products have different characteristics, we then it analyzes the types of the three products, the first is the analysis of core products, core product mainly bank reform according to the customer's opinions, to meet customer requirements of products, among them, the core products are mainly composed of investment products, can bring a certain level of income for the customer, this kind of product mainly has the meaning is the meaning of the economy; Secondly, basic products are the most basic components of a bank, including deposit and loan service systems. Through the analysis of relevant information, we can know that basic products are one of the products that are mainly adopted by bank customers at the present stage. In addition to the above two products, the other one is the extension product. This kind of product is the optimized business in financial products, which is mainly carried out to solve the problems existing in customers. The emergence of the financial industry of science and technology, making the financial products also tend to science and technology, at present, new commercial Banks launched online products, products tend to be virtualized, related to the occurrence of this kind of product is convenient for operation, the user can operate directly on the third-party platform, saves the bank employee working process, improve the user experience of business, to a certain extent, promote the development of China's financial sector.

The second is the service innovation of commercial Banks, which is also the key. Improving the user's experience is one of the main focuses of commercial Banks at the present stage. According to the investigation on the relevant materials, we can know that in the traditional business processing mode, the relevant users need to queue up in the bank for processing, the work efficiency is not high, and a large number of bank employees are needed. At the present stage, the appearance of fintech products enables bank users to conduct business directly on the Internet. Bank employees provide online services for customers, which saves time for both parties, greatly improves the efficiency of work and improves the service quality of commercial Banks. The innovation of the service quality to a certain extent, embodies the financial industry in China has entered a new stage of development, through the analysis of related information, we can know, now most of the commercial Banks to carry out online business to deal with the process, this to a certain extent, also reflects the relevant institutions and government departments in our country in financial technology products.

At the present stage, China's fintech products are still facing some problems in the process of development. How to solve these problems and improve the efficiency of work handling is one of the main concerns of the relevant staff. We chose several development modes mainly adopted by commercial Banks at the present stage for analysis, hoping to solve the problems of relevant personnel:

First of all, the first method is to draw lessons from the successful experience of foreign enterprises, strengthen financial products and technology integration, through the analysis of related information, we can know, financial technology products mainly originated from abroad, because our country financial technology compared with the developed countries there is a certain space for development, as far as possible in order to shorten the gap, the relevant staff should improve their skills, the development of science and technology level, strengthen technology and the concept of financial integration. Financial innovation Banks should learn from the advanced experience of foreign countries and develop their own technical level. They can employ external experts or send overseas students for experience learning. In addition, while drawing lessons from foreign advanced experience, we should pay attention to the combination with the domestic situation, on the basis of the domestic concept of innovation. How to improve the integration of financial products and technology? This is related to one of the main consideration of the current problems, to promote financial products and the depth of the philosophy of science and technology integration, promoting the localization of the financial industry development, develop financial technology products suitable to China's national conditions, in addition, governments and relevant institutions should also improve the attention to the related concept, the appropriate policy and law, promote the development of relevant industries.

The second method is to respect the development environment of the market and develop in accordance with relevant laws and regulations. At the present stage, China's science and technology field has developed rapidly and various new products have emerged, such as cloud computing, artificial intelligence technology and big data. To some extent, the development of these technologies has promoted the development of science and technology in China. Through the analysis of relevant data, we can know that at the present stage, there are still some problems in the integration of China's financial sector and scientific and technological products, especially the safety performance, and there is still a lot of room for improvement. Due to the rapid development of Internet technology in China in recent years, the speed of information dissemination is very fast, so it is very important to improve the security performance of technology and financial integration. Once a link in the security loophole, would bring huge losses to the bank's economic system, also will lose the customer information, reduce the service quality of commercial Banks, affect bank user's daily life, reduce the safety performance of information, therefore, commercial Banks in the process of development must be raised awareness of information security, reduce the happening of the risk situation. Commercial Banks should strengthen cooperation and exchange skills to jointly maintain the environmental stability of China's financial industry and promote the long-term development of the financial industry. In addition, in the process of development, commercial Banks should follow relevant laws and regulations and develop on the basis of abiding by discipline and law.

Through the analysis of relevant materials, it can be seen that commercial Banks in China are gradually developing towards diversification at the present stage. How to improve the progress of development and work efficiency is one of the main concerns of relevant staff at the present stage. If traditional commercial Banks want to achieve rapid development in a short time, they should develop the value of non-financial services, improve communication and cooperation with customers, and increase the application of Internet technology. Through the relevant personnel of the survey, we can know that China construction bank as early as 2017 to carry on the business development work, put forward the cooperation with alibaba, the Internet technology application in the development of commercial Banks to promote the progress of the related industries, not only raised the speed of the commercial bank's own development, has also made innovation to the related products pattern, in recent years, the construction bank has been leading the development of China's commercial Banks. Other commercial Banks should learn from their successful experience. The fundamental meaning of cross-border cooperation is that both parties sign relevant agreements and cooperate on the basis of law to develop each other's advantages and promote the long-term development of both sides. In addition to China construction bank, jingdong finance and industrial and commercial bank of China signed relevant agreements to jointly develop fintech related products. Taking asset management as the main premise of cooperation, the two sides carried out cooperation in various aspects, which not only promoted the development of both sides, but also laid a foundation for the improvement of China's financial concept. "Bank of China - tencent financial technology joint laboratory" was also established.

In short, fintech has brought a positive influence that cannot be ignored for the innovation and development of commercial Banks. However, technology is not omnipotent. Both commercial Banks and citizens should consciously abide by relevant laws and regulations to provide a good environment for the further development of fintech.

Essay一般的写作步骤

相信很多留学生都会写essay，但问到大家essay写作分为哪些步骤的话，可能大家未必答得上来。如果大家真的有这个问题，那么其实大家的essay写作多多少少是有点问题的。下面就给大家讲解一下essay一般的写作步骤，希望大家能有所体会。

1.选择一个话题。谨慎选择一个你感兴趣的话题。

2.选择一个理想的题目。理想的题目是你有所了解的话题。这纯粹是个人的看法与观点。

3.选择essay的写作模板。一篇完整的essay至少需要三部分——引文、正文及结论。引文部分非常重要，它能决定essay的水平，因为它是essay的前部分。读者正是通过引文部分来评判是否对essay感兴趣。此外，引文部分为你的essay打下行文基础，而你essay中的内容都应该以引文中所指示的为依据。

4.构建essay正文。这部分应该详尽地论述你的话题。你应该在正文部分记下所有可用以支撑你的观点的论据。然而，仅仅记下并不足够；你需要详细、清晰地解释他们。每一个要点都必须不同，但同时必须与话题相关。

5.提交论文。提交一篇一页的essay，并列出proposed essay的题目，简述essay的内容，并罗列出参考文献。论及目前你所遇到的任何问题。

6.试想你的话题。一旦定好话题，你就需要运用你的智慧“试想”一下你的话题。你一定能够在脑海中想象你所论述的话题——撰写前必须先构思。这个话题是什么？你感兴趣吗？它有吸引力吗？你能构思出essay的确切部分吗？你脑海中有大致框架吗？

7.尽可能地多问自己问题。记下你认为有用的问题。尽可能使你的话题概念化，那么行文便容易多了。

8.设定现实的目标。你同时需要实事求是地看待你的话题。如果你对此话题只有较少的认识，那么你的首要任务一定是加深了解。

9.着重点。Research essay的正文应该是你的着重点。正文通常都因话题的不同方面被不同的标题分割。决定正文需要什么标题以及标题的放置顺序并不容易。你必须审视你的话题并问问自己，“我应该用哪方面的内容来回答我research的问题？”这或许意味着你需要用一个部分来深入描述论点，用一部分回答与你意见相悖的人的问题以及用一部分来证实你的论点。

10.结论。当你撰写结论的时候，总结一下你的research。

以上就是关于essay一般的写作步骤，看过之后，想必大家都有了自己的体会，然后更好地去写作essay.

After a hundred years of development, the pension system in the UK has gradually changed from being dominated by the government to being jointly undertaken by the government, enterprises and individuals. Generally speaking, the development of the UK pension system has gone through the following four stages.

First, the free pension system. The British government provides 25 pence a week free of charge to people over 70 who earn less than 21 pounds a year, with the nature of social relief.

In the second stage, the contributory pension system was established, and the contributory pension act for widows, orphans and the elderly was promulgated in 1925, which established the nature of contributory pension. Since then, the coverage of pension has been gradually expanded and the level of security has been gradually improved, basically forming a pension system with a wide coverage.

The third stage, the reform of privatization of pension, multi-level pension system gradually formed. In 1959, the British government introduced the national graduated pension scheme. Ordinary residents can choose to pay national insurance tax when they are young and receive a state pension after retirement to guarantee their basic living. Some people with higher incomes can opt to "pay more". At the beginning of the system, participants could opt to "opt out", which means they pay less national insurance tax and participate in employer's pension scheme or individual pension scheme. In the depression of the 1970s, the government wanted to reduce the cost of pensions and reduce the financial burden. After the conservatives came to power, pensions were privatised, with tax incentives to encourage employers to set up occupational pensions and individuals to participate in pension schemes. After the market-oriented reform, the British pension system has formed three pillars: the state pension, the employer's occupational pension and the individual pension.

In the fourth stage, we will clarify the basic functions of the state pension system and further promote the development of a multi-tiered pension system. In 2016, the British national pension system has undergone a significant change, from the original state grading pension plans to gradually shift to only responsible for basic security level of the new national pension plan, that is no longer provide "more pay more" national pension plan, all the residents of the state pension amount is only related to the fixed number of year of pay national insurance, and raise the level of national basic pension. This shift has left the state pension system simple and purposeful, with the sole responsibility for guaranteeing the basic needs of residents in retirement, and more responsibility given to employers' occupational pensions and individual pension schemes.

The UK pension system is composed of State pension scheme, Workplace pension scheme and Personal pension scheme. State pension is paid to National insurance contribution to National insurance account by residents according to the specified proportion. After retirement, residents can receive corresponding pension according to the length of years of National insurance tax payment. The employer's occupational pension plan is provided by the employer for the employees and managed by a third-party trust. The employees and the employer pay a certain fee. After the investment accumulation of the trust, the employees can receive a certain amount of pension from the pension plan after retirement. Individual pension plans are usually offered by specialized financial institutions such as insurance companies, and individuals buy them voluntarily, paying fees and receiving tax refunds.

The UK's state pension scheme has been largely responsible for basic living costs since it was reformed in 2016. British residents pay national insurance tax to their national insurance accounts in proportion to their income. They can receive a certain proportion of the state pension when they reach retirement age after at least 10 years, and a full state pension after 35 years, i.e. 164.35 pounds per week. And the state pension will rise at the highest rate of average wage growth, the CPI and 2.5% a year.

In the UK, occupational pension is initially provided by employers voluntarily, but due to the increasing financial burden in the UK, in recent years, the government compulsively requires employers to provide occupational pension for qualified employees. Big, powerful employers can set up their own pension plans, run by third-party trusts and overseen by employers and employees. Other small and medium-sized employers have the option of participating in the UK government's 2012 National Employment Savings Trust scheme, which provides occupational pensions to their employees. Defined benefit pension scheme Defined contribution scheme Defined benefit pension scheme Defined contribution scheme Type defined benefit plan, the employees in a certain percentage of their salary before retirement after retirement pension, due to the employee retirement income is certain, and does not return on investment and pension plans, once the pension plan assets cannot cover liabilities, employers need to use their own assets, completion should pension in the economic downturn, poor investment environment, this kind of pension scheme will bring great burden. Therefore, most companies in the UK no longer provide occupational annuities of this kind, except that government departments adopt defined-income occupational annuities. The second kind of pension scheme for dc type, namely employees before retirement pension amount is uncertain, staff after retirement, according to the employees pay a fixed number of year, the amount of pay and pension plans investment income to determine the final amount, employee pensions and pension plans are tied to return on investment. Compared with defined-benefit plans, such plans have lower operating costs and are less burdensome for companies, most of which offer them.

Individual annuities plan is provided by the professional financial orgnaization such as insurance company, dweller buys by oneself according to his demand, individual annuities plan is capture capture affirmatory model plan more, the government undertakes duty to pay charge refund. If a resident plans to buy an insurance company individual pension plan, pay 100 pounds per month, the individual income tax rate is 20%, this resident only needs to pay 80 pounds per month to the insurance company, the remaining 20 pounds will be returned to the insurance company by the British tax office.

Essay代写：The operational advantages of drones

下面为大家整理一篇优秀的essay代写范文- The operational advantages of drones，供大家参考学习，这篇论文讨论了无人机的作战优势。随着科技的发展，如今无人机已成为战斗力倍增器的重要因素，各国争相发展无人机事业。鉴于无人机的无人性和自主性，无人机的作战优势主要体现在航程、飞行时间、安全性和成本上面。无人机技术的发展正悄然改变着未来作战的样式和手段，无人机作战将是未来军事行动的发展趋势，无人机将在未来战场中发挥越来越重要的作用。

At the beginning of the 21st century, the United States launched two wars, and drones became a magic weapon in the hands of American commanders. The number of drones purchased by the United States increased significantly. The proud achievements of uav have attracted the attention of all countries in the world. Uav has become an important factor of the multiplier of combat effectiveness, and all countries are competing to develop uav business. At present, with the rapid development of cutting-edge technologies such as artificial intelligence, additive manufacturing and electronic information, the field of military and civil uav develops rapidly. According to statistics, the annual output value of global uav system is up to 15 billion us dollars. This paper tries to analyze the combat advantages of uav.

As a rising force in the air, the function of uav depends on its two attributes: inhumanity and autonomy. Inhuman, so that the aircraft in the implementation of the mission does not need to consider the human factor; Autonomy, which enables the aircraft to perform some routine tasks skillfully to complete automatic operations, can effectively save the battlefield response time.

Unmanned aerial vehicles are lighter in weight and smaller in size due to unmanned aerial vehicles. Small unmanned aerial vehicles such as "big crow" are smaller in size and easier to carry. As there is no need to worry about human fatigue, drones can fly for a longer time. The working time of drones such as predator and global hawk is more than 24 hours, which far exceeds the flying time of manned aircraft. Since it is not necessary to consider the damage of personnel, uav can be applied in a more dangerous battlefield environment. Due to the small radiation signal and improved stealth performance, small uav can accomplish more dangerous and more concealed tasks.

Autonomy enables the uav to operate autonomously at some time, such as autonomous take-off and landing technology and autonomous anti-collision technology, making the uav safer and more reliable. In some cases, machines are more skilled, faster and more efficient than human beings. Unmanned aerial vehicles can effectively reduce training time and combat costs due to the use of automation. No manual operation is required, reducing the battlefield burden on the warfighter and making it possible for one operator to control multiple aircraft.

Given the inhumanity and autonomy of uavs, the operational advantages of uavs are mainly as follows: longer range, longer endurance, more dangerous missions and more cost saving.

The longer the uav can fly, the greater its operational radius. Take the carrier-borne uav x-47b of the us navy as an example, its operational radius is up to 1500 nautical miles, which is much higher than the 500-650 nautical miles of f-18 or f-35, so that the us aircraft carrier is beyond the range of the enemy anti-ship missile. If the aircraft carrier only has man-machine with a relatively close operational radius, the enemy anti-ship missile will pose a serious threat to the aircraft carrier.

Due to its small size, small radar reflection area and stronger stealth performance, the long-endurance uav can be used as an airborne early warning aircraft for advance deployment, advancing the airborne warning line and improving its own situational awareness. In addition, long-endurance uav can offer an important goal of their own day of air protection, uav can flight dozens of hours continuously, without rest, its maintenance and rapid, usually after 8 to 12 hours after maintenance, can continue to perform a task, and the man-machine pilots have more than 10 hours, will be physical strength, poor condition, low efficiency, therefore, the operation of the unmanned aerial vehicle rhythm is much greater than with man-machine.

In the case of interference or damage to the satellite communication of our own side, the high-altitude long-endurance uav can be used as the standby air communication and satellite relay to transmit command and control, intelligence and reconnaissance and other relevant information in real time, so as to ensure the normal implementation of combat operations.

Due to small targets, strong penetration ability and no casualties, uav can penetrate into enemy positions or even deep into the enemy, quickly adapt to the boring, dirty and dangerous battlefield environment, and use its reconnaissance equipment to carry out real-time field reconnaissance and surveillance of the enemy's important targets and main deployment. The U.S. army has developed man-unmanned teams that combine grey hawk and shadow drones with apache attack helicopters to provide forward reconnaissance missions for attack helicopters.

Drones do not need to save themselves, focus on mission completion, become the most loyal fighters, can complete the most dangerous missions. The uav can be used as a decoy to play a pioneer role for the manned aircraft. By sending signals to deceive the enemy's ground air defense system, the uav can expose the target, and the subsequent manned aircraft can strike effectively. During the gulf war, multinational forces used drones to simulate attack aircraft to induce the Iraqi army to turn on various radars. The anti-radar missiles of the multinational forces quickly attacked these turned on radars.

In addition to carrying out reconnaissance and decoy missions, uavs can also fly over enemy frontiers or even deep enough to carry out electronic interference and electronic attacks on the enemy and destroy the enemy's electronic, communication and photoelectric systems. In addition, the drone can penetrate enemy positions, provide target guidance and fire guidance, and conduct precision guided munitions for surgical strikes. Use drones to transport the injured to safety without fear of additional casualties.

Micro-drones can also carry out covert reconnaissance, and once destroyed, there is no need to worry about the ownership of the machine or cause diplomatic disputes. Similar to birds, bees and insects, the birdlike and bee-like drones being developed by the us military will not attract people's attention. They can hide in the defense depth of the enemy for a long time, regularly send information about the enemy's important targets, and carry out intelligence collection and secret destruction missions.

Compared with manned aircraft, uav has lower requirements for platform weight, performance and power, which can effectively save costs. Its price is relatively lower and cheaper. The army and Marine corps purchased more than 7,000 of these drones because of their low price.

Uav has a longer endurance, which means less aircraft are needed for reconnaissance and surveillance in all-day space and time, which reduces the cost of use, maintenance, training and other expenses of the aircraft, thus reducing the lifetime cost of the aircraft, which can be translated into corresponding cost savings.

Remote control of drones can also save costs. Although predator, reaper and other drones complete missions in various regions of the world, their operators are in the United States, and the operators do not need to travel long distances, thus greatly reducing the human cost.

The automatic operation of uav reduces the control of personnel and shortens the training time of personnel, thus achieving cost saving. Taking the x-47b carrier-borne uav as an example, it can autonomously complete accurate take-off and landing operation, which requires a lot of training and repeated practice for naval pilots. Therefore, autonomous take-off and landing technology will significantly reduce training costs and flight costs. In addition, multi-machine control technology and automatic information processing also reduce labor costs and realize cost savings.

The development of uav will become the driving force of the new round of scientific and technological revolution and industrial revolution, and promote the innovation and development of other emerging industries. The development of uav technology is quietly changing the style and means of future combat.
