Calculated Application Of Operations Research In The Field Of Economic Management

In recent years, with the development of Chinese economy, more and more problems on management turn up, such as impractical stochastic service, unreasonable material yummy treats, wrong location plan, unreasonable managing the human resources, which have become the barriers that restrict the enterprises to grow stronger. The operations research is widely used in the economy management system, which can make a good arrangement for the enterprises'wealth and the limited resources and provide a scientific basis for the decision-making. That is to say, the scientific methods will be found to solve those problems using the theory of operations research.In this article, operations research principles and the steps of processing question are elaborated and some examples are utilized to show the importance of the application of the operations research in the economical management. In this article, the optimized models and the algorithm from the combination of the operations research principle with stochastic service and the optimized row in economical management domain are analyzed and the simulation experiment is also carried on using VC++6.0 or Matlab6.1. The two kinds of questions are common in life. Therefore, the optimized model and the algorithm simulation have the enormous practical significance and social value in studying the two kinds of questions.With the help of the studying and application of the theory of stochastic service in the fast-food restaurant, the bank, the video on demand, and the homepage visit, different mathematical models has been established in those fields and its algorithm has been analyzed and the result has been tested. Especially, the application of the theory of lining up used in the video has been studied. According to unpopularity, the program is divided into two parts, popularity and unpopularity. The control method of video frequency based on the unpopularity has been proposed, system instantaneous shift probability has been analyzed and the band width forecast formula of the frequency flows of the different popularity video has been produced. The method of analysis is suitable for other similar stochastic service systems. The row of type problem widely exists in practice and the rectangle to optimize a row of type, which is the problem to be urgent to be solved by many professions, is mainly studied.Through the processing technology of computer graph, one or several components are put in a containing rectangle, then the containing rectangle is arranged, thus the non-rectangular components will be transformed into the question of rectangle to optimize a row of type, the optimized mathematical model will be established and the heuristic algorithm and the simulation algorithm could be utilized to solve the problem of the rectangle to optimize the row of type. The result indicates the algorithm is feasible and effective.
