【摘要】：近年来，我国信息系统工程建设中存在着的以下几方面的问题：信息系统工程的质量达不到用户要求，信息系统工程超出计划交付时间，信息系统工程费用超出预算。究其原因尽管在信息系统工程建设过程中引入了监理机制来规避风险，但是监理工程师对质量、进度、成本实施控制的过程中，，把它们看成一个孤立的个体，没有把它们放到一个整体的系统中来加以控制，造成信息系统建设的失败。本文首先介绍了信息系统工程的概念及其生命周期，然后说明了信息系统工程监理的定义，接着从系统论、控制论的角度进行分析研究，提出监理过程中质量、进度、投资目标的控制必须围绕五大环节，即投入、转换、反馈、对比、纠偏进行。坚持主动控制与被动控制相结合，将质量、进度、投资三大目标作为一个控制整体在信息系统监理实施过程中进行控制。其次研究信息工程监理的三大目标控制的具体内容，分析了信息工程监理对工期、质量、成本在各个阶段的具体控制的流程与方法。接着运用网络技术方法对工程控制的三大目标进行了优化分析，并运用遗传算法进行了求解，为信息系统监理工程师对成本、质量、进度控制提供了具体努力的方向。最后对挣值管理进行了完善修改，监理工程师在实施的过程中，按照完善后挣值法的对工程成本、质量、工期进行合理的控制。本论文还通过一个实际的案例，对模型的可行性和实用性进行了验证。通过该案例的应用分析以及获得的最终决策结果说明本论文的模型具有一定的实用价值。
[Abstract]:In recent years, the following problems exist in the construction of information systems engineering in China: the quality of information systems engineering can not meet the requirements of users, the information systems engineering exceeds the planned delivery time, and the cost of information systems engineering exceeds the budget. The reason is that although supervision mechanism is introduced to avoid risk in the process of information system engineering construction, the supervision engineer regards them as an isolated individual in the process of controlling quality, schedule and cost. They are not controlled in a single system, resulting in the failure of information system construction. This paper first introduces the concept of information systems engineering and its life cycle, then explains the definition of information systems engineering supervision, then analyzes and studies it from the point of view of system theory and cybernetics, and puts forward the quality and progress in the process of supervision. The control of investment target must revolve around five links, namely input, conversion, feedback, contrast and correction. By combining active control with passive control, the quality, progress and investment objectives are controlled as a whole in the process of information system supervision. Secondly, the paper studies the concrete contents of the three objectives control of information engineering supervision, and analyzes the concrete control flow and method of information engineering supervision in each stage of time limit, quality and cost. Then the network technology method is used to optimize and analyze the three targets of engineering control, and the genetic algorithm is used to solve the problem, which provides a specific direction for the information system supervision engineer to control the cost, quality and schedule. Finally, the earned value management is improved and the supervision engineer controls the project cost, quality and duration according to the method of earned value. The feasibility and practicability of the model are verified by a practical case. Through the application analysis of this case and the result of final decision, it is proved that the model of this paper has certain practical value.
