This work applies fuzzy sets to the integration of purchasing, manufacturing and assembling of production planning decisions with multiple suppliers, multiple components and multiple machines in remanufacturing systems. The developed fuzzy multi-objective linear programming model (FMOLP) simultaneously minimizes total costs, total $text{CO}_2$ emissions and total lead time with reference to cus...

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...

Pengendalian stok barang retur dengan proses manufaktur ulang (remanufacturing) merupakan hal penting bagi banyak perusahaan. Seringkali, kompleksitas remanufaktur seperti dalam industri kimia, membuat produk meningkat inventori. Penelitian ini mengkaji sejumlah strategi pengendalian menggunakan kerangka closed loop supply-chain remanufacturing dan simulasi sistem dinamik. Pertama-tama, penelit...

The problem of scheduling the production of new and recoverable defective items of the same product manufactured on the same facility is studied. Items are processed in batches. Each batch comprises two sub-batches processed consecutively. In the first subbatch, all the items are newly manufactured. Some of them are of the required good quality and some are defective. The defective items are re...

Project-based remanufacturing is a kind of service-driven remanufacturing mode, and production scheduling is one of the important issues for project-based remanufacturing system operation. Many uncertain factors exist in the remanufacturing system which lead to the traditional single production scheduling model and approach can not satisfy the requirements for production scheduling in the proce...

Remanufacturing is an industrial process where used products are restored to useful life. This dissertation describes how products can be designed to facilitate the remanufacturing process. It also describes how the remanufacturing processes can be improved to be more efficient. When comparing remanufacturing with other end-of-life scenarios, it is hard from an environmental perspective to dete...

Trade-in remanufacturing is a commonly adopted business practice under which firms collect used products for remanufacturing by allowing repeat customers to trade in used products for upgraded ones at a discount price. This paper studies how customer purchasing behavior and remanufacturing efficiency affect the economic and environmental values of such a business practice. We demonstrate a new ...

In this paper one of the important “end of life options” (remanufacturing) has been analysed. Among the related studies surveyed the various remanufacturing aspects, less attention has been paid to the stochastic process routing. In this regard, a remanufacturing process routing with stochastic activities is modelled as a GERT network. One of the efficient ways to analyse a remanufacturing proc...

Our daily lives and welfare rely heavily on products. Considering that climate change is caused by humans, it is important to handle and use products in a sustainable manner; remanufacturing is one such way to accomplish this. Remanufacturing is an industrial process where products are restored into useful life. However, few products are designed for remanufacturing, which sometimes makes reman...

Remanufacturing (or remarketing) is considered to have a high potential for achieving reduced production costs as well as reduced waste volume, through efficient use of resources. There are some variations of remanufacturing, including component reuse, refurbishing, retrofitting, upgrading, and even reselling as is (i.e., to second hand markets). This paper is an attempt to formally understand ...
