  1. Master Production Scheduling(MPS)

  2. Production Planning and Control System Establishes overall production, workforce, and inventory levels Sales and Operations Planning (S&OP) Determines when specific products will be made, when specific customers orders will be filled, and what products inventory are available to meet new demand Master Production Scheduling(MPS) Calculates the timing and quantities of material orders needed to support the master schedule MaterialRequirements Planning (MRP) Purchasing Control Production Control (PAC)

  3. Demand Resources Strategic planning Resources Planning Sales&Operation Plan. (AggregatedProduction Plan) Forecasts Rough-cut Capacity Plan. Master ProductionScheduling (MPS) Customers Orders Detailed Capacity Requirements Plan. Material Requirements Plan Plan Execution Input /Output Control Purchasing Control Production Control PLANNING AND CONTROL SYSTEM

  4. Master Production Scheduling (MPS) Master Production Scheduling allows the firm to: • „Break down” the aggregated plans made in the SOP into productionschedule of specific products which are ordered by customer • Serve as a plan that uses actual customer orders in addition to forecast data • Serve as a source of information by which it is possible to develop much more specific capacity and resource plans. • Serve as a method to effectively translate customer orders into effectively timed production orders for the facility. • Serve as an effective tool for planning finished goods inventory levels

  5. Master Production Schedule A statement of what the company plans to produce in terms of individualproducts, quantities and planning periods MPS PURPOSE: • A schedule for production orders for MPS items • Drives the MRP calculation • Input to Rough-Cut Capacity Planning • Basis for making delivery promises to customers WHERE APPLICABLE ? In all manufacturing companies

  6. Master Production Scheduling (MPS) Master Production Schedule should take into account: • customers requirements (quantities and delivery time) • capacity and time constraints (be feasible) • production efficiency factors (minimum production batch size, inventory holding level)

  7. Master Production Scheduler Master Production Scheduling Requirements: • Demand forecasts • Customer orders • Safety stock • Orders from Final Product Warehouse Resources: • Materials • Capacity • Over time • Regular time • Subcontracting

  8. MTO MTS A MTS X Master Production Scheduling in production environments SOP – Sales and Operations Plan FAS – Final Assembly Schedule SOP, FAS SOP, FAS SOP, MPS, DRP Final Products Final Products Final Products Modules MPS MTO V Materials Materials Materials MPS Make to Stock Make to Order Assembly to Order Master Production Scheduling depends on the production environment (MTSor MTO or ATO). MPS operates at the level that has the fewest items that need to be scheduled. The subject of planning : • MTS - specific final products • ATO – modules and components to be assembled • MTO – standard components and raw materials

  10. Master Production Scheduling Product: B Lot size: 400 units On-hand: 300 units Projected available – planned inventory available at the end of the week On-hand – current inventory (initial inventory) Lot size – minimal quantity accepted MPS – Master Production Schedule

  11. Master Production Scheduling (Make to Stock environment) Product: B Lot size: 400 On-hand: 300 Projected available - inventory available at end of the week Projected available On Hand MPS Demand forcast = + -

  12. Customer orders entry Demandsources: individualcustomers orders, distributorsorders, final products warehauseorders Product: B Lot size: 400 On-hand: 300 Projected available – planned inventory available at end of the week Projected available On Hand Larger Forcast/Orders MPS = - +

  13. Available to promise Available to promise allows the firm very quickly and realistically promise delivery of products to the customer without any changes in MPS Product: B Lot size: 400 On-hand: 300 Total orders to the next MPS Available to promise Week 1 MPS (1) On Hand = - + Total orders to the next MPS Available to promise Week n MPS (n) = -
