The p-median (PMP) has the objective of minimizing total distance, a customer/patient needs to travel in order to get a service. Various algorithms have been developed to solve the problem and in this paper, an alternative approach of Genetic Algorithm based heuristics is used to solve the problem in minimizing the travelled distance for a patient to get(More)
In this paper, an inventory replenishment model for deteriorating items is developed. Demand for the item varies with time over a finite planning horizon, during which shortages are allowed and are completely back-ordered. The objective is to determine a replenishment policy that minimizes the total inventory cost. A search procedure based on Genetic(More)
The Maximal Covering Location Problem (MCLP) has the objective of maximizing the total demand volume covered by a facility within a maximum allowable travel distance, S. In this paper, three sets of data 30-node, 324-node and 818-node networks with no existing facilities are analyzed as the capacitated model of MCLP (CMCLP) and first solved by the(More)
In this paper, the integrated Production, Inventory and Distribution Routing Problem (PIDRP) is modelled as a one-to-many distribution system, in which a single warehouse or production facility is responsible for restocking a geographically dispersed customers whose demands are deterministic and time-varying. The demand can be satisfied from either(More)
