Abstract:
تسعى المنظمات الخدمية الى تحقيق ميزة تنافسية من خلال اختيار مواقعها بالقرب من الزبائن بهدف تسليم الخدمات بوقت قصير وزيادة عوائدها وحصتها السوقية وتصمم ترتيبها الداخلي بالشكل الذي يمكن من تسهيل تدفق الزبائن والعاملين والموارد والمعلومات بهدف تقليل صفوف واو | Service organizations select locations in a proximity to customers to deliver services quickly, and, meanwhile, increases their revenues and market share. The layout of such organizations should facilitate the flow of customers, employees, materials, and information, to prevent the creation of waiting lines and unwarranted waiting times. The survival of service organizations is hinged, to a great degree, on the right location and layout of such organizations; hence such decisions are conceived strategic in nature. The ongoing researches are still seeking to find scientific methods to help decision makers, in making decisions about the location and layout. This research studies the problem of selecting the location of fuel stations in oil products Distribution Company, and how to prioritize the location, as this decision is still facing the obstacles of complicated procedures and assumptions of decision makers. Furthermore dealing with the decision criteria as same importance without being subjected to the degree of influence of each on the decision. Concerning the arrangement of the fuel stations, they are arranged in a way that does not match with the assumptions of any queuing models, which require one server in each service channel and its reflection on the increase of waiting line and waiting time, which complicate the crisis. The study aims to design an integrated frame work for selecting the fuel stations location and arrange approvals for construction by applying analytic hierarchy process (AHP) on a sample of the stations that received the approval of construction in the company since 2008, using Criteria (ground, environment, social, engineering, legal, and services). Also, the queuing theory and simulation are used to study the proposed layout design for the fuel pumps according to queuing model M/M/s. Also, there was estimation for the performance standards to the proposed layout (number of cars on waiting, number of cars in service, number of cars in the system. filling quantity, filling time, waiting time, total time in the system, idle time) and comparing it with the actual performance standards for sample of fuel stations. The operating of the simulation models is based on a number of assumptions that reflect the actual reality together with the queuing theory. This study is important because its knowledge contribution of with service systems in general and the fuel stations in particular. Also the study provide objective solutions to the company by shortening the procedures and the time it takes to select the location and layout design in a way that achieve optimal investment in station space and reduce the waiting line, waiting time and idle time. Thus, this study is an attempt in Iraqi services environment through coincidence between the strategic decisions of operations management in one study. The study proved the efficiency of AHP and its ability to shortening time and efforts required to make decision of selecting stations location and arrange construction issue approvals, depending on set of criteria that have been identified in this study. Also, the simulation results confirmed the proposed layout performance standards exceed the actual layout performance standards. Finally, the study recommended the need to adopt AHP in selecting the location and granting approvals for construction of stations according to multiple criteria, and to adopt the proposed layout according to the queuing theory in designing layout of the fuel stations
