Shortening cycle times in multi-product, capacitated production environments through quality level improvements and setup reduction

► We optimize production cycle times by investing in setup time and defect rate reductions. ► We determine optimal levels of setup time, defect rate reductions, and l investments required. ► The problem is constrained by demand requirements, budget limitations, and manufacturing and warehousing capacity. ► We provide a convex geometric programming heuristic to find approximate solutions to non-linear models. ► We empirically determine the important factors for product-specific and joint-product quality improvements.
