The second method is to formulate the problem with fuzzy times as a multi objective linear programming model and use the weighted additive method to unite the objective functions as a single objective function with a defined weights and then solve the problem classical linear programming we found the shortest path in both the methods are same and minimum time in the first method equal to the optimal solution for second method , and in addition minimum fuzzy time in the second method Is obtained.

Abstract: تعد مشكلة النقل من المشكلات الاساسية التي تعالجها البرمجة الخطية وتحليل هذه المشكلات له اهمية كبيرة في اختزال التكاليف العالية للنقل وكذلك اختزال الوقت والجهد اللازم لذلك. وتعتمد عملية التحليل بصورة اساسية على ايجاد حل اساسي ابتدائي مقبول (Starting Basic | Transportation problem is one of the basic subjects that are quired by liner programming and the process of analyzing the transportation problems has great importance to reduce the high cost of transportation and the time and effort needed to submit. the analyzing process basically depends on finding a fundamental solution Elementary acceptable (Starting Basic Feasible Solution), to be the firm ground to proceed to another solutions until we reach the optimal solution, which represents the true measure of process Decision making.However (Starting Basic Feasible Solution), is better (cheaper) the number of iterations that required to reach the best solution will be less. therefore in this study we have to review the traditional ways of finding a fundamental solution which is (row Minimum, Modified row Minimum, column Minimum, Modified column Minimum, the north West corner, least cost, Russell's approximation method, and Vogel's approximation method). In addition to review four new methods two of them are published (Zidan's method and average method). and the other two methods are founded by the researcher as a result of his search & study (the first and second suggested method SM.1 and SM.2).to know the efficiency of these methods we should be tested, therefore we will use the simulation in trial side of the research to generate (100) of random transportation problems and solve it by the above methods for a comparison between these methods depending on the results that we gain from solutions. Based on the results of the comparison relied on the method that gave the best results in finding Basic Solution to be used in the application side of research, which is the process of constructing three transportation models to transfer of the distribution network for petroleum products, white available in stores alkhoznip and refineries (processing centers) to be distributed to counties of Iraq (demand centers) by tanker trucks (tankers) and put this models in a transportation schedules to solve it by the beast basic method and to be improved until we reach the optimally

Abstract: تعتبر مشكلة النقل احد الاساليب الرياضية المهمة التي تساهم في عملية اتخاذ القرار المناسب في نقل السلع من مصدر انتاجها او تجهيزها الى مراكز طلبها المتعددة باقل التكاليف الممكنة, وضمن حدود العرض والطلب في كافة المنشات الصناعية, الاقتصادية والانتاجية. وفي ه | The problem of transportation is one of the important sports methods that contribute to the decision - making process in the transfer of goods from the source of production or processing to the centers of multiple demand at the lowest possible costs, and within the supply and demand in all industrial, economic and productivity. In this thesis, a model was presented for the problem of unbalanced transportation within budget constraints and demand for specific periods with a lower limit and an upper limit. This model was solved using the Interval point method to find the optimal solution to the problem of transportation with budgetary constraints. Which contributed to the selection of suitable solution for administrative and economic decision makers according to their potential and financial availability, as well as the use of the zero - point method to solve the linear model of the problem of transportation proved to be efficient and easy to apply. The simplex programming method was used to solve the transportation problem For. This method has proven to transportation larger volumes and lower transportation costs for Lower and Upper demand but exceeded the budget allocated by the company to transportation the product. The total transportation cost of the black oil (fuel oil) in the way of the Interval point method to the lower limit (187700000) and the cost of the upper limit (247600000) and did not exceed the budget allocated for transportation from the company (225500000), but reduced the cost of transportation to (22557808) (9,705.47) tons. The general linear programming method (Simplex) was the lower limit cost (180280000) and the cost of the upper limit (240000000) and the total cost of transportation was (233097.76) exceeded the budget allocated for transport by the company by (7597.76) and quantities transferred (10004.09) tons.

In view of the importance of markove's chains in explaining, and analyzing many of the phenomenae through succession, our research incentive has therefore came to represent markov chains applications on the DNA and considering the conditional transitional probabilities of these chains elements for its great importance in finding the hereditary genetics from DNA compositions. Markov chains has been implemented for the probable alignment of the first, second, third, fourth, and fifth orders. Three means depending on these alignments have been used. Experimentation on four of DNA chains was carried out for human growth hormone and relied on DNA succession for comparison between the three ways that nominate the chain of the greater probability to represent the gene.In addition, a program was created to code and translate the three models of the ORF for the DNA succession and the chains for the three models which start with the start code and end with the stop code. The program was written by Visual basic language to carry out these operations and to yeild sequence alignment between the human growth hormone gene and other chains.The program implemented DNA chains in which the nucleotide number is less than 3000 bases examplified by the human growth's hormone, mouse and chicken growth hormone.As well, entrotoxins produced by E.coli, salmonella , shigella representing prokaryotes were also included one of the most significant conclusion reached is that markov assessment method of calculated weights by means of Chi Square is the best mean for identifying genes from DNA sequences.

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
