Manufacturing Resource Planning (MRP II)

Manufacturing Resource Planning II (MRP II) is an extension and enhancement of the original Material Requirements Planning (MRP) system that emerged in the 1980s. MRP II takes a more comprehensive approach to production planning and control by integrating additional functionalities beyond materials management. It incorporates various manufacturing processes, resource management, and enterprise-wide planning to optimize production Efficiency, resource utilization, and overall business performance.

Key Features of Manufacturing Resource Planning II (MRP II)

  1. Materials Management: MRP II continues to include materials management features from Material Requirements Planning (MRP I), such as Bill of Materials (BOM) management and material planning.
  2. Capacity Scheduling: MRP II takes capacity scheduling to a more advanced level, considering machine capacities, labor availability, and other resources.
  3. Shop Floor Control: MRP II focuses on real-time monitoring and control of shop floor activities to ensure production schedules are met.
  4. Master Production Schedule (MPS): The MPS is an essential component of MRP II, providing a detailed schedule of what, how much, and when to produce based on customer orders and forecasts.
  5. Financial Integration: MRP II integrates production scheduling with financial management, allowing cost analysis, budgeting, and financial reporting.
  6. Human Resources Management: MRP II incorporates human resources data to optimize workforce planning and utilization in line with production needs.
  7. Demand Management: MRP II considers demand forecasting and management to better align production with market demand fluctuations.

Operation of Manufacturing Resource Planning II (MRP II)

  1. Bill of Materials (BOM) Management: MRP II maintains accurate and up-to-date BOMs for all products, ensuring that the right components and materials are considered.
  2. Master Production Schedule (MPS): The MPS is created based on customer orders, sales forecasts, and production capacity, considering both material and resource constraints.
  3. Capacity Scheduling: MRP II analyzes available capacities for resources and aligns production schedules accordingly.
  4. Material and Resource Planning: MRP II calculates material and resource requirements based on the MPS, inventory levels, and Lead Times.
  5. Shop Floor Control: MRP II closely monitors production activities on the shop floor, enabling real-time adjustments to maintain schedule adherence.

Benefits of Manufacturing Resource Planning II (MRP II)

  1. Improved Resource Utilization: MRP II optimizes the use of machines, labor, and other resources, leading to better resource utilization.
  2. Enhanced Production Scheduling: With advanced capacity scheduling and real-time monitoring, MRP II enables efficient production scheduling and execution.
  3. Cost Optimization: By integrating with financial management, MRP II enables better cost analysis and control, contributing to cost optimization.

Challenges of Manufacturing Resource Planning II (MRP II)

  1. Complex Implementation: Implementing MRP II can be challenging due to the complexity of integrating multiple functionalities and departments.
  2. Data Accuracy and Integration: MRP II relies on accurate data from various departments, necessitating seamless data integration and sharing.


Manufacturing Resource Planning II (MRP II) is an advanced manufacturing planning and control system that extends the capabilities of MRP I. By integrating materials management, capacity scheduling, shop floor control, human resources management, and financial analysis, MRP II offers a comprehensive solution to optimize production Efficiency, resource utilization, and overall business performance. While implementing MRP II can be complex, its benefits in improved resource utilization, production scheduling, and cost optimization make it a valuable tool for manufacturing companies seeking to achieve operational excellence and competitiveness.
