Statistics For Inventory Control Management

Many organizations today have mastered the basics of inventory management for production raw materials, but do not realize that inventory control for maintenance supplies and equipment spare parts requires very different procedures and objectives.

Inventory decisions can impact equipment uptime. Poor warehouse controls can derail the best laid plans of the maintenance and engineering function.

Course Objectives

At the end of the course participants will be able to:

• Provides a framework for improving ROI and reducing inventory investment

• Highlights the problems found in most spares warehouse environments
• Reveals the best approach to improve inventory record accuracy
• Outlines the fundamentals of warehouse organization and management
• Identifies the correct supporting roles for the purchasing function and suppliers
• Suggests the key weaknesses of CMMS tools that must be addressed
• Improves the coordination of inventory management with maintenance management
• Provides opportunity to practice course concepts and create a personalized plan for action
