IE 651: Inventory Planning and Management Systems
Prerequisite: Exposure to relevant concepts at undergraduate level and instructor consent
Production flow processes; Fundamental types of systems for efficient inventory management in large integrated production flow systems; PUSH/feed forward and PULL/feedback control elements incorporated in prevalent systems in practice; MRP, MRP II, JIT Kanban, OPT, Hierarchical Planning Systems; Hybrids of push & pull systems; issues of decentralization of control; role of information and data base systems; effecting integration in supply chains.
Determinants of Lead Times in batch manufacturing; impact of setup times, batch sizes and uncertainties in demands, shop yields and material supplies; controlling bottlenecks and delays through capacity allocation policies.
Effectiveness of MRP & MRP II systems; alternatives for Master Production Scheduling processes, ordering policies , policies governing safety stocks/times and other approaches for robust performance under uncertainties; Cyclic Planning Systems; CRP; role of finite-resource forward scheduling; shop floor control over batch sizes and transfer quantities.
Approaching JIT production ; cellular manufacturing; Kanban card count and batch size decision; underlying (s, S) type control for production authorization; variants of Kanban & CONWIP type systems
