Spare Parts Planning

A quick and reliable supply of spare parts for successful after-market service is growing in importance. The time it takes to repair a product is heavily dependent on the availability of a part. It is a growing challenge to secure this availability as products and their parts become more complex. Maintaining optimized stock levels, without unnecessarily tying up capital is of utmost importance.


It is safe to say that the management of spare parts has earned its designation as the supreme discipline of logistics planning. Aside from quick and dependable delivery service, customers expect reliable information regarding price, availability and delivery times. Several challenges stand in the way of making these lofty service promises. Due to variable, fluctuating requests and sporadic sales, predicting demand for spare parts is no easy task. Based on this high level unpredictability, many companies tend to hoard stock in an effort to reduce repair times by increasing the availability of spare parts.
