The return of a product is often one of a series of transactions that a consumer undertakes in search of a good. Recognizing this, we analyze returns as part of a product search process: Upon returning a product, consumers may immediately purchase an alternative one, which they may later replace...

Problem definition: We consider two competing electronic waste (e-waste) recovery channels, each of which consists of a collector and a recycler. Collectors obtain donated e-waste and sell the collected items to recyclers or in the secondary market, while recyclers process e-waste and sell the...

Motivated by emerging practice in the cut flower industry, we consider a periodic-review inventory system for a perishable product with a lifetime of two periods. There are two separate customer demands for the new product with two-period remaining lifetime and the old product with one-period...

We study the competition between two remanufacturers in the acquisition of used products and the sales of remanufactured products. One firm has a market advantage; we consider two separate cases where either firm could have an acquisition advantage. The problem is formulated as a simultaneous...

Circular Economy (CE) aims to maintain the value of products, components, materials, and resources in the economy for as long as possible. Current end of life (EoL) product circularity decision-making methods are focused on technical and economic factors neglecting other crucial areas such as...

The false hair industry represents a case of growing demand and depleting natural resources, in addition to a significant environmental impact of synthetic alternatives. Despite the growth of the false hair industry, there is a lack of research to date regarding the complete life cycle of false...

New generations of high-technology products are frequently launched before the previous model is sold out. Customers have an incentive to end the use of their old product and purchase a new one with the latest technological innovations. The unsold old models become less attractive, while the...

Introducing proprietary parts to gain a competitive edge is a well-known, yet poorly understood strategy original equipment manufacturers (OEMs) adopt. In this paper, we consider an OEM which sells new products and competes with an independent remanufacturer (IR) selling remanufactured products....

Unlike consumer durable goods, high technology products have shorter life cycles. Many companies launch new items at a fast rate of innovation. As a result, the latest products often compete in the same market with earlier-generation products. In addition to brand-new products, used products...

With the fast development and frequent changes of the engineering products, natural resources are arbitrary exploited and the environment is used without repayment, which causes many problems of great magnitude such as zoology damaged all over the globe, resource waste and depletion,...
