Using Modularization in Supply Chain Network Models
The aim of this paper is to present an optimization model for the design of supply chain network with special consideration paid to the bills of materials (BOM). We consider the design of a multi-echelon supply chain network in a single period, multi-country and deterministic context for a company in the aeronautic industry. The network comprises of a number of raw material suppliers’ sites and a number of subcontractors’ sites. These elements are to be selected from a set of potential suppliers and potential subcontractors so that the overall cost is minimized. In our model, we incorporate notions such as modularization and odd products as a new way to ensure flexibility in the production assembly. Odd products are to be assigned to modules. This helps to reduce the number of products to be handled at the final assembly line. The Mixed Integer Programming (MIP) model developed finds the optimal network that minimizes total cost by determining the assignment of raw materials to suppliers, modules to subcontractors and odd products to modules. The model considers multiple sourcing where the number of parts sourced from a supplier or subcontractor must be greater than a lower bound as dictated by purchasing contracts or to keep the supplier motivated. The model determines the production level at each node as well as the quantity of products to be shipped from one node to another so that the customer demand is met. The model is formulated and computational results are presented.
