Consumable spare parts play an important role during regular and periodic maintenance activities depending on equipment criticality of a manufacturing firm. Usually, these spare parts are consumed together on a regular basis to different equipment with a high percentage of commonality. Complete or partial shutdown of maintenance activity may happen if there is shortages in any of these common p...

Link restoration and path restoration are the two major techniques used for telecom network restoration in DCS (Digital Cross-connect System) mesh networks. For rerouting to be possible, su cient spare capacity must exist in the links of the chosen alternate paths. Path restoration results in lower additional cost compared to link restoration. Tra c splitting can be used to further reduce the a...

This paper analyzes the value of different sources installed base information for spare part demand forecasting and inventory control. The is defined as set products (or machines) in use where installed. Information on number still use, age products, their parts, well reliability may indicate when a will fail trigger new part. current literature unclear which this adds most – should thus be col...

In the Industry 4.0 scenario, additive manufacturing (AM) technologies play a fundamental role in automotive field, even more traditional sectors such as restoration of vintage cars. Car manufacturers and restorers benefit from digital production workflow to reproduce spare parts that are no longer available on market, starting with original components, if they damaged. This review focuses this...

In this paper, a new model has been presented to determine the number of spare transformers and their locations for distribution stations. The number of spare transformers must be so that they need minimum investment. Furthermore, they must be sufficient for replacing with transformers that have been damaged. For this reason, in this paper a new purpose function has been presented to maximize p...
