Abstract
We consider the item assortment problem of a vending machine. Our goal is to determine the optimal assortment of items and the optimal replenishment cycle time of the vending machine. We model the problem as mathematical programming problems. We formulate this problem as an integer linear programming problem to get tight lower bounds and apply the column generation method for its linear relaxation problem. We also propose two algorithms to get upper bounds, one based on tabu search and the other on multiple start local search. Our numerical experiments on a real world instance and randomly generated instances show that our methods generate good solutions within a reasonable computational time.
