Here, we consider single vendor-buyer model with multi-product and multi-customer and multi-facility location-production-distribution problem. It is assumed that the players of the supply chain are coordinated by sharing information. Vendor manufactures produce different products at different plants with limited capacities and then distribute the products to the consumers according to determini...

This paper deals with the facility location problems with balancing on allocation clients to servers. Two bi-objective models are considered, in which one objective is the traditional p-median or p-maxian objective and the second is to minimize the maximum demand volume allocated to any facility. An edge deletion method with time complexity O(n) is presented for the balanced 2-median problem on...

Collaborative spatial decision-making environments in which group members individually and collectively pursue solutions to ill-structured problems have a unique set of cartographic visualization requirements. In this paper we restrict our focus to the domain of facility location problems and describe several new map types that are designed to support the process of making comparisons among alt...

A reliable model for Location-Allocation (LA) is proposed based on 0-1 mixed integer programming model presented by Baumol-Wolfe. A heuristic algorithm (HA) based on wavelet analysis is used to solve LA problem, which incorporates different customers’ demands into a minimum wrap-net. It indicates that customers are allocated to one facility or one cluster if they satisfy that the distance is ne...

This paper studies a reliable facility location problem with facility protection that aims to hedge against random facility disruptions by both strategically protecting some facilities and using backup facilities for the demands. An Integer Programming model is proposed for this problem, in which the failure probabilities of facilities are site-specific. A solution approach combining Lagrangian...

— We treat a discrete uncapacitated facility location problem where the installation cost per facility is a gênerai nonlinear function of the number of established facilities. Assuming a convexity proper ty, Mirchandani and Jagannathan developed a heur is tic solution procedure for this problem. Hère, we show how to modify their algorithm in order to get and prove exact solutions and, at the sa...

In this study, we discuss the capacitated facility location-allocation problem with uncertain parameters in which the uncertainty is characterized by given finite numbers of scenarios. In this model, the objective function minimizes the total expected costs of transportation and opening facilities subject to the robustness constraint. To tackle the problem efficiently and effectively, an effici...
