Study Notes
Introduction to Operations Management
- Focus on scheduling, particularly MRP (Material Requirements Planning) and ERP (Enterprise Resource Planning).
- Reading materials include Chapters from Stevenson and Heizer & Render on Operations Management.
What is MRP?
- MRP is a methodology that converts master schedule demands for finished products into specific time-phased requirements for components and materials.
- It involves the planning and scheduling of manufacturing processes.
MRP Inputs
- Master Schedule: A timeline outlining the production schedule and delivery timelines.
- Bill of Materials (BOM): A detailed list outlining all raw materials, components, and assemblies necessary for producing one unit of a product.
- Inventory Records: Information on available materials and stock levels, tracking both independent and dependent demand.
MRP Outputs
- Planned order releases detailing the sizes and timing of necessary orders to meet production schedules.
MRP II
- An enhancement of MRP that integrates additional data such as production capacity and financials, focusing on overall resource planning.
ERP
- ERP is a comprehensive software solution that manages business processes and integrates various functions across an organization, including MRP.
Example Case Study: Wood Shutters Production
- Example involves orders for 100 and 150 shutters, due in weeks 4 and 8, respectively.
- Each shutter requires two frames and four slatted wood sections.
- Fabrication of wood sections takes one week; frames have a lead time of two weeks.
Lot-for-Lot Ordering
- Planned order releases are equal to net requirements per period, calculated based on demand and current inventory availability.
Lot-Size Ordering
- Involves ordering larger quantities (320 units for frames and 70 units for wood sections), which may lead to surplus stock.
Assembly and Lead Time Planning
- Assembly requires one week; total cumulative lead time to produce shutters is three weeks, factoring in production of frames and slatted wood sections.
Bill of Materials Example
- Detailed quantities per item required for producing one wood shutter:
- 1 wood shutter per unit
- 2 frames per shutter
- 4 slatted wood sections per shutter
Assembly Design
- Visual representation indicating the hierarchy of components and their quantities for efficient production.
