| ============================================================================== | |
| 4. PRODUCTION ORDER MANAGEMENT | |
| ============================================================================== | |
| 4.1 Creating Production Orders | |
| Production orders are the foundation of manufacturing execution in the MES. Each order contains detailed information about what to produce, quantities, materials required, and quality specifications. | |
| To create a new production order: | |
| 1. Navigate to Production Orders → New Order | |
| 2. Enter order information: | |
| - Order Number (auto-generated if left blank) | |
| - Product Code and Description | |
| - Quantity to Produce | |
| - Due Date | |
| - Priority Level (Low, Medium, High, Critical) | |
| 3. Select the production route and work centers | |
| 4. Specify material requirements and bill of materials | |
| 5. Define quality control checkpoints | |
| 6. Assign operators and equipment | |
| 7. Save and release the order for production | |
| Order Status Workflow: | |
| Created → Released → In Progress → Completed → Closed | |
| 4.2 Material Requirements Planning | |
| The MES automatically calculates material requirements based on the bill of materials (BOM) and current inventory levels. When a production order is created, the system: | |
| 1. Explodes the BOM to determine raw material needs | |
| 2. Checks current inventory availability | |
| 3. Creates shortage reports for missing materials | |
| 4. Generates purchase requisitions if integrated with ERP | |
| 5. Reserves materials for the production order | |
| Material consumption is tracked in real-time as operators scan barcodes or enter consumption data manually. The system maintains lot traceability and automatically updates inventory levels. | |
| 4.3 Work Order Routing | |
| Production routing defines the sequence of operations required to manufacture a product. Each route consists of multiple work centers with specific: | |
| - Operation sequence numbers | |
| - Setup time requirements | |
| - Run time per unit | |
| - Required skills and certifications | |
| - Quality control points | |
| - Standard operating procedures | |
| The MES uses routing information to: | |
| - Calculate production lead times | |
| - Schedule equipment and labor | |
| - Track work-in-process inventory | |
| - Monitor operation efficiency | |
| - Enforce quality control procedures | |
| ============================================================================== | |
| 5. INVENTORY TRACKING | |
| ============================================================================== | |
| 5.1 Inventory Management Overview | |
| The MES provides comprehensive inventory tracking capabilities for raw materials, work-in-process, and finished goods. All inventory movements are tracked with full traceability including lot numbers, serial numbers, and expiration dates. | |
