Laser direct deposition provides an attractive and cost effective means for repairing or remanufacturing high value engineering components. This study demonstrates the successful repair of defective voids in turbine airfoils based on a new semi-automated geometric reconstruction algorithm and a laser direct deposition process. A Boolean difference between the original defective model and the fi...

Remanufacturing is a concept of strategic importance that enables a significant part of the value added to a product during its initial production to be retained. It is no longer acceptable to dispose continually of strategically important materials in landfill sites or waste the energy associated with their processing. Remanufacturing is the process by which used products and assemblies are re...

The paper investigates interactions in a two-period closed-loop supply chain consisting of a single manufacturer and a single remanufacturer. In the context of recycling and remanufacturing by the remanufacturer, the manufacturer and remanufacturer choose different production strategies. By comparing the costs, profits and equilibrium quantity of supply chain members in decentralized and centra...

This study deals with joint decisions on pricing and production lot-sizing in a closed-loop supply chain consisting of manufacturing and remanufacturing operations. This study emphasizes the economic analysis of this hybrid system with substitution between the new and the remanufactured versions of the same product. We develop analytical models under a newsvendor framework bearing the following...

This paper focuses on the application of soft computing in remanufacturing system, in which end-of-life products are disassembled into basic components and then remanufactured for both economic and environmental reasons. The disassembly activities include disassembly sequencing and planning, while the remanufacturing process is composed of product design, production planning & scheduling, and i...

This paper describes an environment where two products are offered, one is remanufactured and the other is all-new. Examining the trade-offs between the customer's utility and production cost variables, the model identifies conditions under which the remanufacturing product may coexist with the all-new product. The paper concludes with some insights on why remanufacturing can be successful with...

In this paper we investigate the complexity of the economic lot-sizing problem with remanufacturing (ELSR) options. Whereas in the classical economic lot-sizing problem demand can only be satisfied by production, in the ELSR problem demand can also be satisfied by remanufacturing returned items. Although the ELSR problem can be solved efficiently for some special cases, we show that the problem...

remanufacturing is an industrial process that makes used products reusable. remanufacturing is a way to establish a closed-loop supply chain. one of the important aspects in both reverse logistics and remanufacturing is pricing of returned and remanufactured products (called cores) that it has been noticed in this paper. in addition, in this paper the researchers have tried to present a mathema...

This paper deals with the production-dependent failure rates for a hybrid manufacturing/remanufacturing system subject to random failures and repairs. The failure rate of the manufacturing machine depends on its production rate, while the failure rate of the remanufacturing machine is constant. In the proposed model, the manufacturing machine is characterized by a higher production rate. The ma...

In the last two decades, many countries have enacted product take-back legislation that holds manufacturers responsible for the collection and environmentally sound treatment of end-of-use products. In an industry regulated by such legislation, we consider a manufacturer that also sells remanufactured products under its brand name. Using a stylized model, we consider three levels of legislation...
