Decomposition/aggregation-based dynamic programming optimization of partially homogeneous unreliable transfer lines

摘要: The general problem of buffers sizing for mean work in process/inventory minimization a particular class single part unreliable manufacturing flow lines, subjected to constant rate demand finished parts, is analyzed. Two variants the are considered: average process when there fixed requirement on parts availability buffer next last; an aggregate measure and backlog complete line considered. A fluid model production employed. control policies interest suboptimal, strictly decentralized, unambiguously parameterized by size levels. Optimization policy parameters based analysis structural properties associated dynamic program. latter built around approximate, decomposition based, levels dependent theoretical expression performance measure. nature related approximations discussed numerical results programming procedure reported. Scalability computations demonstrated. suggest that optimal, both form balancing just time internal principle, place.
