Purpose: We aim to examine the capacitated multi-item lot sizing problem which is a typical example of a large bucket model, where many different items can be produced on the same machine in one time period. We propose a new approach to determine the production sequence and lot sizes that...

This paper considers the dynamic lot sizing problem of H. M. Wagner and T. M. Whitin with the assumption that the total cost of n setups is a concave nondecreasing function of n. Such setup costs could arise from the worker learning in setups and/or technological improvements in setup methods....

This paper considers a dairy industry problem on integrated planning and scheduling a Mixed Integer Linear Programming (MILP) formulation is introduced to integrate tactical and operational decisions with uncertain demand and a heuristic approach is proposed to decompose time buckets of the...

This paper focuses on a novel approach to cold chain management of perishable products. We extend the classical and frequently applied Economic Order Quantity model (EOQ) for its application in multi-echelon supply chains for highly perishable products. Literature shows that order-level...
