Optimization method of agricultural material chain operation logistics center site selection

Abstract

The invention discloses an optimization method of agricultural material chain operation logistics center site selection, belonging to the technical field of logistics center site selection optimization. The technical scheme specifically comprises: putting forward an optimization model for agricultural material chain operation logistics center site selection; converting into new single logistics center site selection, new multiple logistics center site selection and logistics center site selection with limited number; based on the analytic hierarchy process principle, calculating the weight of the target function of the optimization model for agricultural material chain operation logistics center site selection; by taking example of transportation problem solutions, synthesizing addition rules in multiple-target decision analysis, and repeatedly solving until obtaining an approximate optimal solution. The proposed model truly reflects the planning process of the agricultural material chain operation logistics center, satisfies the minimum requirements of logistics link cost and ensures that the model better conforms to reality. The model not only can calculate the optimal site of the agricultural material chain operation logistics center but also can know the throughput of a selected logistics center and realizes the optimal site selection of single logistics center or a plurality of logistics centers.

Description

technical field The invention relates to a technology for site selection optimization of a logistics distribution center, which is used for the planning, design and operation management of the logistics distribution center for chain operation of agricultural materials. Background technique Chain operation is a modern circulation mode that achieves economies of scale by implementing centralized procurement, decentralized sales, and standardized operations for several retail enterprises. The chain operation of agricultural materials is to introduce this advanced operation mode in the circulation of agricultural materials. In villages and towns, franchisees and training methods are used to find chain operators of agricultural materials, and the headquarters of the chain company distributes various brands of pesticides, fertilizers, seeds and other agricultural products. The materials are then distributed by the agricultural materials supermarket and managed by the head office. ...

Problems solved by technology

(4) Considering the cost factors such as the fixed operating cost and variable operating cost of the logistics distribution center, and aiming at the maximum benefit that the logistics distribution center can obtain, a heuristic algorithm is proposed, and it is considered that the third-party logistics enterprises can simultaneously operate in multiple locations at one time. It is uneconomical and unscientific to build a small but large number of logistics distribution centers. It is also unreasonable to build a number of reasonable construction sites through models based on a logistics forecast and build them in stages, because the regional logistics situation occurs. When changing, it is not feasible to build according to the original forecast, and re-forecasting is obviously wasteful

Since the location of the logistics distribution center is a complex system engineering, there are many factors to be considered, and most of the existing research results are considered under specific constraints. The theory is complicated and it is difficult to effectively guide the practice.
