| Abstract |
As a typical sustainable product-service system, the aero-engine overhaul service aims to recover the functionality to fulfil certain flight hours and thrust requirements. How to configure the overhaul service with various sub-services is a key issue in industry. In this paper, a use-oriented aero-engine overhaul service configuration approach is proposed with two methods: overhaul service configuration and part repair service configuration. The overhaul service configuration method decomposes the overhaul service into various sub-services and creates a hierarchical service tree model, taking the cost and energy consumption into consideration. Based on the sub-service filtering and selection rule, the bill of exchange service comes with the bill of discard service. The part repair service configuration method matches each part repair procedure service with a proper service provider. Some non-dominated bills of repair services are obtained by minimizing the repair service cost, finishing time deviation and energy consumption. Considering the multi-objective character of the overhaul service configuration problem, these two methods result in some Pareto solutions to fulfil the service requirements. Through implementing the approach as a prototype, a case study is shown to illustrate the use-oriented aero-engine overhaul service configuration approach and verify its feasibility. A bridge between the flight hours and thrust requirements and the overhaul service configuration results is built when the cost and energy consumption are minimized. The study contributes to the shift of aero-engine overhaul services from the add-on services to sustainable use-oriented product-service systems. (C) 2016 Elsevier Ltd. All rights reserved. |
