Study Notes
Distribution Requirements Planning (DRP) Overview
- DRP is a vital tool for managing inventory and distribution across multiple locations.
- DRP records are crucial for the functionality of DRP systems.
- Facilitates a connection between internal and external manufacturing planning and control (MPC) systems.
Relationships with Other Planning Systems
- Links between master production scheduling (MPS) and material requirements planning (MRP) help ensure a cohesive supply chain process.
- Consistent data formats are utilized in both DRP and MRP.
Demand Concepts
- Customer purchases are part of independent demand rather than dependent demand.
Warehouse Integration
- DRP generates data specific to each warehouse in systems with multiple facilities.
Planning Data Preparation
- DRP provides essential information for manufacturing, logistics, and sales operations planning.
Functionality of DRP
- Extends visibility in manufacturing planning and control (MPC) and summarizes detailed field information.
Calculations Using DRP Data
- Shipping Quantity: Calculation of shipping quantity is critical; in scenarios provided, the shipping quantity was determined to be 300 units.
- Lead Time: In examples, lead time was established as 3 periods, indicating delayed restocking.
- Safety Stock: Most likely safety stock value was calculated to be 150 units.
- Planned Shipments: In specific scenarios, planned shipments were consistently stated as 50 units across several periods.
Order Requirement Approaches
- Time-phased order point (TPOP) uses forecasts to determine requirements.
Data Aggregation and Efficiency
- The implosion process accumulates DRP data from multiple warehouses for central analysis, enhancing efficiency.
- Safety stock aggregation from various warehouses leads to reduced overall levels of safety stock while maintaining service levels.
Forecasting and Bias
- In DRP systems, forecast bias significantly impacts supply chain efficiency and is considered a more serious issue than forecast errors.
- Adjustments to forecasts using error add-back methods can affect future predictions, exemplified by a revised forecast of 120.
Customer Service and Cost Implications
- Increasing customer service goals generally results in higher inventory levels and customer service levels, but does not directly lead to lower total costs.
- Lowering inventory levels contributes to reduced total costs while typically lowering service levels.
Labor Cost Management
- Reducing labor cost goals often leads to higher inventory levels yet can also result in lower total costs.
Specific Situational Insights
- Changes in safety stock policies might be indicated by specific patterns in the DRP records, such as projected available balances and planned shipments.
