A pooling strategy for flexible repair shop designs
( SciTePress , 2018 , Conference Paper)We discuss the design problem of a repair shop in a single echelon repairable multi-item spare parts supply system. The repair shop consists of several parallel multi-skilled servers, and storage facilities for the repaired ... -
A sorting based efficient heuristic for pooled repair shop designs
( Elsevier , 2020 , Article)In this paper, we address the assignment problem of skills to servers (e.g., repairmen) in a multi-server repair shop of a spare parts supply system. This type of assignment problems tends to be hard in general, due to the ... -
A model to evaluate acquisition price and quantity of used products for remanufacturing
( Elsevier , 2012 , Article)In this paper, an analytical model is proposed to evaluate optimal acquisition price and quantity policy based on the quality of returned used products that are subsequently used for remanufacturing. The model is developed ... -
Analytical models for predicting oil recovery from immiscible CO2 injection: A literature review
