Production planning and cell formation in dynamic virtual cellular manufacturing systems with worker flexibility

Most traditional cell formation problem procedures ignore any changes in demand and part mix variation. However, in today´s business environment, products life cycles are short, and demand volumes and product mix can vary frequently. In this paper, a new mathematical model for production planning in a dynamic virtual cellular manufacturing system is developed under conditions of multi period planning horizons, with demand and part mix variation and worker flexibility. To validate and verify the proposed model, two examples are solved by LINGO software package.
