Contents for MRP JIT in MPC JIT Example JIT Application Non-repetitive JIT JIT Software Managerial Implications
JIT in MPC: Major Elements • Zero-x: inventory, transaction, disturbance,… • Mainly suitable for high volume, repetitive manufacturing • Physical Changes: SMED, improved quality, TPM, Poka-yoke, continual improvement, worker involvement
JIT in MPC • JIT Orientation includes several action plans: -Reduction of set-up and lot size -No defects in production -Continual improvement -Worker involvement -Cellular manufacturing • Impact on MPC: JIT can eliminate standard shop floor reporting systems, reduce costs of detailed shop scheduling, reduce WIP and Lead Time, support better vendor scheduling • Hidden Factory: One factory makes product and the other factory processes transactions on papers and computer systems • Ex) Ordering, execution and confirmation of materials moving from on location to next, costs of receiving, shipping, expediting, data entry and processing, accounting and error follow up • Logistical Transactions, Balancing Transactions, Quality Transactions, Change Transactions,…
JIT in MPC • We need a factory having large bandwidth( flexible to volume and variety change)
JIT Applications • Inventory is like water, as it goes down, the problem becomes visible
