A production model to reduce Batch dispersion and optimize traceability

Traceability is a needed strategic service in any production context. It can be used to improve security, control quality, manage complex chains, minimize recalls, limit incurred risk and reassure consumers. In this paper the problem of minimizing the quantity of recall and the number of batches constituting a given finished product is treated, when products are characterized by a 4-level “disassembling and assembling” bill of material. A mathematical Mixed Integer Linear Programming model (MILP) is proposed and the results of experiments obtained with CPLEX software are presented.
