Purpose: The purpose of this paper is to examine the efficacy of diversification-based learning (DBL) in expediting the performance of simulated annealing (SA) in hub location problems. Design/methodology/approach: This study proposes a novel diversification-based learning simulated annealing...

In this paper, a multi-item inventory control model is developed for perishable items in which production (or supply) is instantaneous with no lead time. Demand is uniform and deterministic and shortages are not allowed. The model is solved analytically for minimizing the total inventory cost,...
