Material control involves the oversight and regulation of materials required in a production process. It ensures that materials are available at the right place and time, in the right quantities, and are properly accounted for. This balance is crucial to prevent production delays due to a lack of materials while avoiding the financial burden of overstocking inventories.
Historical Context
Material control has its origins in the early stages of the Industrial Revolution when mass production and assembly lines became common. The need for efficient handling and usage of materials became apparent to avoid costly downtimes and to enhance productivity. Over time, various methodologies and technologies have been developed to refine material control practices.
Types/Categories of Material Control
Material control can be categorized into several types:
- Order Control: Ensuring timely ordering and reordering of materials.
- Inventory Control: Monitoring and managing inventory levels.
- Quality Control: Maintaining the quality of materials to ensure production standards.
- Budgetary Control: Managing costs related to material acquisition and usage.
Key Events
- 1920s: Introduction of Economic Order Quantity (EOQ) model by Ford W. Harris.
- 1950s: Development of Material Requirements Planning (MRP) systems.
- 1980s: Emergence of Just-In-Time (JIT) inventory systems.
Detailed Explanations
Economic Order Quantity (EOQ): EOQ is a model used to determine the optimal order quantity that minimizes the total cost of ordering and holding inventory. The EOQ formula is:
- \( D \) = Demand rate
- \( S \) = Ordering cost
- \( H \) = Holding cost per unit per period
Material Requirements Planning (MRP): MRP systems help in scheduling material deliveries based on production schedules, ensuring materials are available as needed without overstocking.
Just-In-Time (JIT): JIT systems focus on reducing inventory levels and delivering materials just as they are needed in the production process, thus minimizing storage costs and reducing waste.

Importance
Effective material control is crucial for:
- Reducing production delays.
- Optimizing inventory levels and reducing carrying costs.
- Enhancing production efficiency and productivity.
- Ensuring quality standards are met.
- Reducing wastage and improving resource utilization.
Applicability
Material control is applicable in various industries, including manufacturing, construction, pharmaceuticals, and more, where maintaining an efficient production process is critical.
Examples
- Manufacturing Industry: A car manufacturer ensures all parts are available for assembly to avoid delays.
- Construction Industry: Proper control of building materials to ensure timely project completion and cost management.
Considerations
- Accurate forecasting of material needs.
- Timely reordering to avoid stockouts.
- Efficient storage and handling to maintain material quality.
- Implementing technology for better inventory management.
Related Terms
- Inventory Management: The process of ordering, storing, and using a company’s inventory.
- Supply Chain Management: The management of the flow of goods and services.
- Lean Manufacturing: A production practice that considers the expenditure of resources in any aspect other than the direct creation of value to be wasteful.
Comparisons
- Material Control vs. Inventory Management: While inventory management focuses on tracking and managing inventory, material control ensures materials are available for production as needed.
- Material Control vs. Supply Chain Management: Supply chain management covers the entire flow of goods from supplier to customer, whereas material control focuses specifically on materials within the production process.
Interesting Facts
- The concept of JIT was popularized by Toyota in Japan to streamline production and reduce costs.
Inspirational Stories
Toyota’s implementation of JIT revolutionized the auto industry by significantly reducing waste and improving efficiency, setting a global benchmark for production processes.

Summary
Material control is a critical aspect of production management, ensuring the availability of materials at the right place and time, in the right quantities, and maintaining proper accounting. By balancing these elements, organizations can avoid production delays, reduce costs, and improve overall efficiency. Through historical developments and various methodologies like EOQ, MRP, and JIT, material control has evolved to meet the demands of modern industries, making it indispensable for maintaining a smooth and efficient production process.
