This paper describes a multi-objective evolutionary approach for solving multi-objective service facility location problems with dynamic demands. In this problem, the demands of customers are changing over a given period and one service facility will be built in each period. The objective of this problem is to determine a construction plan, while optimizing the transportation costs, facility maintenance...
We consider an integrated location-inventory-routing problem where the decision marker needs to realize the integrated decisions of facility location, inventory control, and vehicle routing for a logistics distribution system owned to a chain enterprise. This distribution system consists of a center warehouse, multiple potential distribution centers (DCs) and multiple retail stores. Retailer stores...
The mining programming of accumulated bauxite should comprehensively consider the site selection and rational utilization of resources. The mixed integer programming model on optimization of site selection and rational ore blending was constructed on the basis of the theories of logistics planning, operations research, etc. Take Taipingbei mine in Pingguo bauxite as the example, the results which...
Timeliness is one of the most important objectives that reflect the quality of emergency rescue. To provide timeliness, the most obvious way is to increase the number of service facility available. Unfortunately, increasing the number of facility is generally impossible due to capital constraints. In such a case, the strategy for emergency facility location becomes a crucial issue. This artic discusses...
This paper describes a model that seeks to simultaneously optimize the location of multiple-server, congestible facilities in order to realize company's maximal total captured demand. The effective demand at each customer demand node is elastic to the travel cost to the facility, and to the congestion at that facility. We propose a greedy heuristic for the resulting problem formulation, and provide...
This paper is aimed to solve the multi-facility location problems of distribution centers by multi-objective decision method. After analyzing the requirements and characteristics of distribution time, it put forward a multi-facility location model in which the distribution cost was taken as decision objective and the distribution time was changed to a group of constrains. It designed a bi-step heuristics...
