A Hybrid Algorithm Forset Covering Problem 1

چکیده
In this paper we propose a hybrid algorithm for the set covering problem (SCP), which combines L-class enumeration, genetic algorithm (GA) and Lagrangean heuristic. The lexicographical enumeration of L-classes in the linear relaxation of SCP ensures optimality of the resulting solution. Both heuristics are used for obtaining the initial approximate solution. The linear subproblems in L-class enumeration are also tested by means of Lagrangean relaxation. The results of computation experiments appear to be promising.

Hub Covering Location Problem Considering Queuing and Capacity Constraints
In this paper, a hub covering location problem is considered. Hubs, which are the most congested part of a network, are modeled as M/M/C queuing system and located in placeswhere the entrance flows are more than a predetermined value.A fuzzy constraint is considered in order to limit the transportation time between all origin-destination pairs in the network.On modeling, a nonlinear mathematica...
متن کاملEfficient Solution Procedure to Develop Maximal Covering Location Problem Under Uncertainty (Using GA and Simulation)
In this paper, we present the stochastic version of Maximal Covering Location Problem which optimizes both location and allocation decisions, concurrently. It’s assumed that traveling time between customers and distribution centers (DCs) is uncertain and described by normal distribution function and if this time is less than coverage time, the customer can be allocated to DC. In classical mod...

متن کاملDynamic Hub Covering Problem with Flexible Covering Radius
Abstract One of the basic assumptions in hub covering problems is considering the covering radius as an exogenous parameter which cannot be controlled by the decision maker. Practically and in many real world cases with a negligible increase in costs, to increase the covering radii, it is possible to save the costs of establishing additional hub nodes. Change in problem parameters during the pl...
