Initial spare parts supply of an orbital system

Condition based spare parts supply

We consider a spare parts stock point that serves an installed base of machines. Each machine contains the same critical component, whose degradation behavior is described by a Markov process. We consider condition based spare parts supply, and show that an optimal, condition based inventory policy is 20% more efficient on average than a standard, state-independent base stock policy. We further...

Reducing Costs of Spare Parts Supply Systems via Static Priorities

We study static repair priorities in a system consisting of one repair shop and one stockpoint, where spare parts of multiple repairables are kept on stock to serve an installed base of technical systems. Demands for ready-for-use parts occur according to Poisson processes, and are accompanied by returns of failed parts. The demands are met from stock if possible, and otherwise they are backord...

Redesigning Toyota’s spare parts supply chain using tabu search

In Schittekat and Sörensen (2009) we describe the development of a tabu-search based software tool to support tactical decision-making in the spare parts supply chain of Toyota Europe. For the distribution of spare parts to car dealers in Europe, Toyota operates two hubs, one in Germany and one in the Czech Republic. Car dealers requiring spare parts may place an order by telephone or the inter...
