Operators of long field-life systems like airplanes are faced with hazards in the supply of spare parts. If the original manufacturers or suppliers of parts end their supply, this may have large impacts on operating costs of firms needing these parts. Existing end-of-supply evaluation methods are focused mostly on the downstream supply chain, which is of interest mainly to spare part manufactur...

An optimization model is proposed to redesign the supply chain of spare part delivery under demand uncertainty in a specified planning horizon. Long term decisions involve new installations, expansions and elimination of warehouses handling multiple products. It is considered which warehouses should be used as repair work-shops to store, repair and deliver used units to customers. Tactical plan...

The change of market and the explosion of product variety have led to increased automation and the need for complex equipment. Therefore, the reliability and the maintainability of the equipment play an important role in controlling both the quantity and quality of the products. In order to ensure specified availability and reliability of production process, preventive maintenance (PM) should b...

In industrial contexts the proportion of the stock range that is devoted to spare parts is often considerable (e.g. Vereecke and Verstraeten, 1994) and small improvements in spare parts management may be translated to substantial cost savings (Eaves and Kingsman, 2004). Many research projects have considered issues related to the management of spare part inventories, but very few studies have e...

Design of BOM configuration for reducing spare parts logistic costs Muh-Cherng Wu and Yang-Kang Hsu Department of Industrial Engineering and Management, National Chiao Tung University, Hsin-Chu, Taiwan, ROC Abstract This paper proposes an approach to reduce the total operational cost of a spare part logistic system by appropriately designing the BOM (bill of material) configuration. A spare par...

We consider an inventory model for spare parts with two stockpoints, providing repairable parts for a critical component of advanced technical systems. As downtime costs for these systems are huge, ready-for-use spare parts are kept on stock, to be able to quickly respond to a breakdown of a system. We allow for lateral transshipments of parts between the stockpoints upon a demand arrival for a...

As additive manufacturing (AM) evolves to become a common method of producing final parts, further study of this computer integrated technology is necessary. The purpose of this research is to evaluate the potential impact of additive manufacturing improvements on the configuration of spare parts supply chains. This goal has been accomplished through scenario modeling of a real-life spare parts...

This work aims for image categorization by learning a representation of discriminative parts. Different from most existing part-based methods, we argue that parts are naturally shared between image categories and should be modeled as such. We motivate our approach with a quantitative and qualitative analysis by backtracking where selected parts come from. Our analysis shows that in addition to ...

Accurate estimation of spare part demand is challenging in the case intermittent or lumpy demand, characterised by infrequent occurrence and variability size. While prior research has considered effect exogenous variables on there a lack considering effects repair quality aggregated behaviour across fleets assets under influence multiple simultaneously acting drivers failure. This provides new ...
