Heterogeneity in Consumers’ Usage Behavior and Environmental Impact Assessment

In this study, we have developed a framework for understanding the heterogeneity and uncertainties present in the usage phase of the product lifecycle through utilizing the capabilities of Agent Based Modeling (ABM) technique. An ABM framework has been developed to… Read More

Environmental Impacts of Industry 4.0

Industry 4.0 graphic

Smart manufacturing in an Industry 4.0 setting requires developing unique infrastructures for sensing, wired and wireless communications, cyber-space computations and information tracking. While an exponential growth in smart infrastructures may impose drastic burdens on the environment, the conventional Life Cycle… Read More

Optimal Sorting Policies in Remanufacturing Systems

Pile of electronic components.

The quality of used products returned to recovery facilities is often highly uncertain. Quality grading and sorting policies are immediate solutions that are used in remanufacturing systems to handle this source of variability in incoming products. In this study, we… Read More

Environmental Evaluation of Product Design and the Role of Consumer’s Repair Behavior

Tiny workers on a motherboard

Consumers might be willing to repair their broken devices as long as the associated repair costs do not exceed an undesirable threshold. However, in many cases the technological obsolescence actuates consumers to retire old devices and replace them with new… Read More

Business Outcomes of Repairable Products

Inside of a cell phone

Product repair is a suggested post-purchase activity toward extending the useful lifespan of a product. However, repairability has not received sufficient attention by manufacturers. Even if the product repairability is not explicitly claimed by manufacturers, it is expected by consumers,… Read More

The current status of the consumer electronics repair industry in the U.S.

Computer repair warehouse

Consumer electronics are turning into consumable devices nowadays, and consumers generally show little inclination to repair broken products due to the lack of repair infrastructures and relative high repair costs. On the other hand, technical, operational, and economic barriers impede… Read More

Integration of Product Life Cycle Data toward Remanufacturing of Waste Electrical and Electronic Equipment

Computer monitor showing usage data

The aim of this study is to incorporate the information collected from the product’s usage phase into making appropriate end-of-use and end-of-life (EOU/L) recovery decisions (e.g., reuse, remanufacturing, recycling, refurbishing, disposal) for consumer electronics. The analyses are focused on discovering… Read More

Agent Based Simulation Optimization of Waste Electrical and Electronics Equipment Recovery

Box of old printers

The profitability of Electronic waste (e-waste) recovery operations is quite challenging due to various sources of uncertainties in quantity, quality and timing of returns originating from consumers’ behavior. The cloud-based remanufacturing concept, data collection and information tracking technologies seems a… Read More

Study of Current Trade-In Programs Available for Used Consumer Electronics

Cash for phones kiosk

This study carries out an analysis of various trade-in programs available for cellphones in the United States. Product trade-in is one of the methods to recover End-of-Life (EoL) products from consumers. Currently, there is a lack of knowledge amongst consumers… Read More

Multi-purpose Disassembly Sequence Planning
