This article presents a column generation algorithm to calculate new improved lower bounds to the solution of maximal covering location problems formulated as a p-median problem. This reformulation leads to instances that are difficult for column generation methods. The traditional column generation method is compared with the new approach, where the reduced cost criterion used at the column se...

This paper studies capacitated single-allocation hub covering location problem with fuzzy cover radius and travel time. Objective of hub covering problem is to find the minimum number of hubs considering the maximum allowable travel time. Computational results show that due to uncertainty, number of hubs and the allocation of non-hub nodes to hub nodes are changed. This paper proposes heuristic...

Province X in Indonesia has a significant problem with trash that been challenging to address. The Environment Agency therefore desires construct an inorganic Trash Management System. four potential locations various capacities. purpose of this research is locate treatment system's best possible site and allocate each TPS less than 30 km more over from the chosen system, respectively, ensure ov...

This paper presents a multi-objective mixed-integer non-linear programming model for congested multiple-server discrete facility location problem with uniformly distributed demands along the network edges. Regarding capacity of each and maximum waiting time threshold, developed aims to determine number locations established facilities their corresponding assigned servers such that traveling dis...

we consider the queueing maximal covering location-allocation problem (qm-clap) with an m/m/1 queueing system. we propose a new solution procedure based on decomposition of the problem into smaller sub-problems. we solve the resulting sub-problems both with a branch and bound algorithm and with the meta-heuristic grasp. we also solve the entire model with grasp. computational results for these ...
