When components fail on equipment they usually require a replacement part. When those parts are not availability and can have significant costs in loss of productivity and place expensive demands on your logistic system to expedite the delivery of the part. There is a trade off between the risk in having no parts available and the stocking levels of your parts stores. A parts analysis will be able to optimise your stocking levels commensurate with your tolerable risk.
The initial purchase price of equipment can be insignificant with the sustainment costs. One sustainment cost which must be predicted and managed is spare parts. A spare parts analysis will help inform the quantity of your initial parts purchase, but also allow you to (in conjunction with an aging analysis) predict the parts costs into the future.
Acuitas can help you conduct a spare parts analysis to support your equipment regardless of its life cycle stage.
