Abstract: بعد التطور الكبير الذي حصل في مجال الحاسبات والاهتمام المتزايد باسلوب المحاكاة ومن خلال دراستنا وبحثنا في اساليب وطرائق بحوث العمليات كان الزاما علينا دراسة وتطبيق احدا اساليب بحوث العمليات المعروفة والتي نشعر بان لها فائدة عظيمة في خدمة قطاعات واسعة في ا | After the great development happened in computers field, the increasing interest in the simulation method, and through our study and research in methods and techniques of operations researches, it was necessary to study and apply one of the known operations researches methods, which we feel that it has a great benefit in serving many sectors in the society, and that is the simulation method.So we decided to merge between simulation and an other method which is not less important than it, which is Reliability.In the last years, the great and increasing interest in studying reliability method was due to the rapid technical development and using complex electronic systems, and relating between it and simulation method is an important thing, so we tried in this research to build a simulation model suitable for the system to measure its reliability and for two different study cases.The fist case is when it is possible to build a mathematical model (primary) for the system. Before starting with forming of reliability system, we must first specify the type of the system that we are going to work on. We chose surplus system to be our study system, because of its capability to provide many choices, in addition to that it permits increasing the reliability spite of external environmental pressures. Because of our many objectives that we wish to achieve in this stage of increasing the reliability, reducing the total cost and total weight of the designed system, we used multi - objective models. And for achieving desired objectives, we formed the model as a case of programming of nonlinear mixed integer numbers. After we had built the mathematical model for the system, we have now a model with three objective functions (reliability - cost - weight) and one condition of size. But when these objectives became unclear in their objective nature, it is possible to reform the case within the fuzzy theory, so we have in this case a reliability system with fuzzy objectives. To solve models like this, it had been made a computer program with Q - Basic language to find the results using FAGP and FNLP methods with the assistance of Monte - Carlo simulation method to find the perfect reliability for the surplus system.As for the second case when it is impossible to build a pre - model for the system, and this is what happens when we have a complex systems and nets, in which the normal methods becomes useless for the total reliability of the system, so we use the simulation method (flow method) and in a direct way to find the reliability.The flow method is applied to Al - Quds electric power distribution station, in which it had been made a computer program with Q - Basic language to find the total reliability for the station and lost power in the year, in addition to determine the number of breakdowns in the specified period, and we tried using simulation to improve the reliability of the station by adding a spare parts

Abstract: نظرا لاهمية نظرية الالعاب وخاصة نظريات احتكار القلة في دراسة واقع التنافس بين الشركات او الحكومات وغيرها، قام الباحث بربط القياس الاقتصادي بهذه النظريات لتشمل كافة السياسات المتعددة المستعملة من تلك الشركات بعد ان كانت تعتمد على الكمية والسعر فقط وتم تطب | Due to the importance of the theory of games especially theories of oligopoly in the study of the reality of competition aming companies or governments and others the researcher linked theories of oligopoly to Econometrics to include all the policies used by companies after these theories were based on price and quantity only the researcher applied these theories to data taken from Pepsi Cola and Coca - Cola In Baghdad Steps of the solution where stated for the models proposed and solutions where found to be balance points is for the two companies according to the principle of Nash.The theory of Cournot is based on the assumption that the total amount sold is fixed and is shared among the parties of monopoly (Companies). Aggregate supply is supposed to be determined and the price is set and supply meets demand. It also assumes that the relationship between price and quantity is linear : Quantity is inversely proportional to the price. the researcher has developed a proposed model for the expansion of the model to include all the policies used by oligopoly companies such as advertising and others.The model of von Staklberg is applied when there is a market leader and the rest of the companies are subsidiaries It takes the same relationship between price and quantity in the theory of Cournot that is the second company determines. the quantity that it wants to produce which will be restricted to the first company. This will be the first company the leader, and the second company to be its subsidiary. The researcher also to included all the policies used by oligopoly companies after linking the model to theories of econometrics.The Bertrand model depends mainly on determining the prices not quantities, as in the models of Cournot and von Staklberg. It is supposed that the price of competing companies in some way affects the price of a single company. The researcher also included all the policies used by oligopoly companies after the model was based on the price, quantity and sale price of the competing company only by linking the model to theories of econometrics
