Introduction:

The ultimate measure of the reliability of equipment is the cost to maintain it.   Maintenance cost typically includes the cost of labor and parts to perform repairs.   In many cases, it is also reasonable to assign a cost to down time.  For example, while equipment is undergoing repairs, other costs may be incurred such as lost production, idle employees, etc.  Maintenance costs can be sobering when realistic down time costs are combined with the costs of parts and labor.  CSR's WinR-DP™ software tool can be used to estimate maintenance costs by machine as well as identifying the failure modes that contribute most to maintenance costs.

Benefits:

• Understand the costs to maintain equipment,
• Identify failure modes that contribute most to maintenance costs,
• Identify opportunities to reduce cost, and
• Develop a realistic view of the value versus cost of spares inventories.

Capabilities:

• Develop reliability model directly from maintenance records,
• Develop maintenance cost model from maintenance records, and
• Analyze maintenance costs including cost sensitivities.
