Abstract

With the increasing variety of product models and the growing need for flexibility in mixed model assembly lines, the number of required parts at the border of line (BoL) is increased. To efficiently utilize the limited space at the BoL, various feeding policies may be implemented. However, this leads to additional preparation and transportation costs, as parts should be repackaged in preparation areas, frequently referred to as supermarkets. Minimizing those costs require assigning each part to suitable feeding policies. These tactical decisions must be made after the facility layout is determined. However, existing models in the literature currently overlook layout and fleet size constraints and assume a greenfield situation. To address this gap, we propose a mathematical model to assign parts to feeding policies and supermarket locations. The objective is to minimize total costs, including replenishment, preparation, transportation and usage costs, while taking into account the existing layout and fleet size constraints. By incorporating these constraints in our model, we aim to provide practical solutions which closely reflect real-world circumstances.
