Abstract
Most traditional cell formation problem (CFP) procedures disregard any changes in demand and part mix variation. However, in today’s business environment, the life cycle of goods is short, and demand volumes and product mix can frequently vary. In this article, a mathematical model for production planning in a dynamic virtual environment is proposed which includes an extensive coverage of the important manufacturing features, including a consideration of multi-period planning horizons with demand and part mix variation, machine capacity, the main constraints are demand satisfaction in all over period, machine availability, machine time-capacity, and availability of workers. VCMS combines the robustness and flexibility of process orientation with the advantages of product orientation, which is expected to appreciate throughput time performance. To validate and verify the proposed model, computational results are presented by solving a number of numerical examples, with a linearized formulation.
