مطالعه در انتخاب محل مرکز تدارکات اضطراری چند هدفه بر اساس AHP

Due to the particularity of location selection in logistics center, a multi-objective location selection model is given based on AHP theory, and the interrupt delay constraint is applied on the basis of considering the environment, economy and technical factor, the time minimization objective is priority to cost minimization objective. Finally, the feasibility and effectiveness of this model are verified by MATLAB simulation results.

Recently, the disasters occur frequently, it is necessary to establish an effective emergency logistics system. The emergency logistics centers (ELC) should be established in a suitable place, which play a role of distribution center, therefore the location selection is paid more and more attention.The traditional location selection is taking the cost minimization as objective [1], however, due to the particularity of emergency logistics, the time minimization is taken as the objective, and then the cost minimization is considered on this basis, and a multi-objective location selection model is given

In this paper, the construction process of AHP is analyzed, and the influence factors of the ELC are established, on the basis of reasonable assumption, a location selection model with the time minimization constraint is given by using the combination of AHP and objective optimization. The concept of time delay is applied, the optimal scheme is calculated by MATLAB simulation, and the feasibility of this method is proved, which provides a stable basic condition for the establishment of whole ELC
