Abstract

An efficient allocation of space in Work-in-Progress (WIP) areas is a key factor for a smooth flow in production, as inadequate planning can lead to bottlenecks, machine idle time and delays. This is especially critical in situations of a high occupation rate as well as limited space. We present an optimization approach for pallet-like production processes illustrated by the working flow in a plant. Our approach is based on mixed-integer linear programming (MILP) and the model allocates order blocks to lanes of varying sizes, while considering the production plan of machines before and after the WIP areas, coupling possibilities of lanes as well as different sequence requirements on lanes. The allocation is optimized according to plant-specific needs, including suitability of the lanes for the orders, lanes kept free for potential changes and blocks of the same order being assigned near each other. We illustrate our approach using synthetic data to mimic the production process of a real plant.
