مدل سازي دو هدفه براي مسيله توزيع مواد سوختي در شبكه با انبار توزيع چندگانه

Bi-objective modeling for a fuel distribution problem in a multi-distribution warehouse centers

افزايش چشم‌گير جابه‌جايي مواد خطرناك نگراتي هاي را در مورد صدمات به انسان و طبيعت به‌وجود آورده است، بنابراين كاهش ريسك به‌عنوان معياري مهم در محاسبات در نظر گرفته مي‌شود. به‌طور خاص در اين مقاله يك مدل دو هدفه خطي مختلط عدد صحيح براي مسيله توزيع مواد سوختي در شبكه با انبار توزيع چندگانه ارايه مي‌گردد، به‌نحوي كه مجموع هزينه انتقال و تاسيس انبار و مجموع ريسك براي انتقال مواد سوختي از انبار توزيع به نقاط تقاضا حداقل مي‌شود. براي صحه‌گذاري مدل رياضي، يك مثال عددي حل مي شود و نتايج حاصل ارايه مي‌گردد.

Since hazardous material transportation has been dramatically increased in terms of quantity, their incident impacts are getting to be known as a serious concern. Therefore, transport risk is usually considered as a main factor in hazardous material transportation and management. In this paper, a bi-objective mathematical model is developed for solving the fuel distribution problem, in which routing and location problems are solved simultaneously. While the problem is formulated as a mix-integer programming (MIP) model, distribution centers are considered as candidates, in which its main aims are to select the best set of establishing centers and find the best routes for carrying fuels from selected distribution centers to gas stations. The proposed model is eventually validated using the experimental data. Finally, the associated results are analyzed and the conclusion is provided.
