[Show abstract][Hide abstract] ABSTRACT: This paper addresses a mixed integer programming (MIP) formulation for the
multi-item uncapacitated lot-sizing problem that is inspired from the trailer
manufacturer. The proposed MIP model has been utilized to find out the optimum
order quantity, optimum order time, and the minimum total cost of purchasing,
ordering, and holding over the predefined planning horizon. This problem is
known as NP-hard problem. The model was presented in an optimal software form
using LINGO 13.0.
