In the event of failure of the product, level of repair analysis (LORA) is used to determine (1) whether the defective component should be discarded or repaired and (2) where this repair is made. In the literature, these repair operations are made with the aim of minimizing the total life cycle cost of the product. In this paper, we develop a multi-objective decision model that minimizes both the repair time (affected by lead times) and the repair costs. Our proposed model also considers the movement of the defective components to be performed by multiple transportation modes such as highway, railway, and airway. We use the epsilon constraint method to generate the Pareto frontier and analyze the trade-off between total repair costs and total repair time. We demonstrate the approach on an example problem.

A New Multi-Echelon Repair Network Model with Multiple Upstream Locations for Level of Repair Analysis Problem Bicakci, Ismail; İÇ, YUSUF TANSEL; Karasakal, Esra; DENGİZ, BERNA (2021-10-01) Level of repair analysis (LORA) determines (1) the best decision during a malfunction of each product component; (2) the location in the repair network to perform the decision and (3) the quantity of required resources in each facility. Capital goods have long life cycles and their total life cycle costs are extremely high. LORA, which can be done repeatedly during the life cycle of the product, both at design and product support phase, plays an important role in minimising the total life cycle costs of cap...
A Stray Magnetic Flux-Based Robust Diagnosis Method for Detection and Location of Interturn Short Circuit Fault in PMSM Gurusamy, Vigneshwaran; Bostancı, Emine; Li, Chen; Qi, Yuan; Akin, Bilal (Institute of Electrical and Electronics Engineers (IEEE), 2021-01-01) © 1963-2012 IEEE.Early diagnosis of interturn short circuit (ITSC) fault is essential to prevent catastrophic electrical machine failures. Along with the detection, locating the faulty winding at its incipient stage is also critical to reduce the outage duration and operation losses. This article proposes a practical method to detect the ITSC fault and locate the faulty winding in permanent magnet synchronous motors (PMSMs) through stray magnetic flux monitoring. It is shown that relying on the fundamental ...
A linear programming approach to quaity improvement project and product mix selection under inspection error and rework Şarbak, Nedret; Köksal, Gülser; Department of Industrial Engineering (2006) In this study, the effect of inspection error on the product mix and quality projects selection in a manufacturing environment where rework and inspection errors exist is examined. It is assumed that the products (items) for which rework is necessary are reprocessed at a separate work center and 100% inspection is performed for the products both after rework and processing operations. Markov chain approach is used to compute yield and rework rates. In addition, nominal-the-best type of a quality loss functi...
Analysis of Three Indoor Localization Technologies for Supporting Operations and Maintenance Field Tasks Taneja, Saurabh; Akçamete Güngör, Aslı; Akinci, Burcu; Garrett, James H.; Soibelman, Lucio; East, E. William (American Society of Civil Engineers (ASCE), 2012-11-01) Locating building components that need to be worked on during maintenance tasks is critical for timely repair of the component and mitigation of the damage. The process of locating a component or a person in a facility is called indoor localization. The objective of this research study is to analyze the feasibility of three indoor localization technologies for supporting operations and maintenance (O&M) field tasks; namely, wireless local area network (WLAN), radio frequency identification (RFID) tags, and ...
Analyzing the effects of inventory cost setting rules in a disassembly and recovery environment Akcali, Elif; Bayındır, Zeynep Pelin (Informa UK Limited, 2008-01-01) In this study we consider a disassembly and recovery facility receiving end-of-life products and facing demand for a specific part that is disassembled from the product and then recovered. The disassembly and recovery operations can be either performed before hand, or upon customer arrival. In the latter case, a discount on the selling price is applied to compensate the customer for waiting for the completion of the disassembly and recovery operations. One of the dificulties faced in planning for such a sys...
