Spare Parts Management

Risk-based optimization of plant maintenance inventory

If you do not have that critical spare part when you need it, you may be in big trouble. On the other hand, it is impossible to keep an extra factory in the storeroom. We do not know what the future will bring, but there is an analytical way to minimize the expected costs.

Use this form to calculate the costs whether or not you buy and keep the critical spares. The calculation is based on statistical methods and is used to optimize your maintenance stores. Enter your figures and estimations, and you will be presented with a buy, or not buy, recommendation.

For the calculation we need to estimate downtime costs, the failure frequency, and the lifetime of the machinery where it will be used.
