“…Through upgrading, a remanufactured core could be of higher quality than its new and original version (Khan et al, 2018). The challenge from a reverse logistics point of view is to design the upgradability into the product (Aziz et al, 2016). For the flow of our argument, we follow the BSI assumption "that remanufacture applies to like-for-like products".…”

Purpose Remanufacturing is the only end-of-life (EOL) treatment process that results in as-new functional and aesthetic quality and warranty. However, applying mental model theory, the purpose of this paper is to argue that the conception of remanufacturing as an EOL process activates an operational mental model (OMM) that connects to resource reuse, environmental concern and cost savings and is thus opposed to a strategic mental model (SMM) that associates remanufacturing with quality improvements and potential price increases. Design/methodology/approach The authors support the argument by empirically assessing consumers’ multi-attribute decision process for cars with remanufactured or new engines among 202 car buyers in China. The authors conduct a conjoint analysis and use the results as input to simulate market shares for various markets on which these cars compete. Findings The results suggest that consumers on average attribute reduced utility to remanufactured engines, thus in line with the OMM. However, the authors identify a segment accounting for about 30 per cent of the market with preference for remanufactured engines. The fact that this segment has reduced environmental concern supports the SMM idea that remanufactured products can be bought for their quality. Research limitations/implications A single-country (China) single-brand (Volkswagen) study is used to support the conceptualised mental models. While this strengthens the internal validity of the results, future research could improve the external validity by using more representative sampling in a wider array of empirical contexts. Moreover, future work could test the theory more explicitly. Practical implications By selling cars with remanufactured engines to customers with a SMM that values the at least equal performance of remanufactured products, firms can enhance their profit from remanufactured products. In addition, promoting SMM enables sustainable business models for the sharing economy. Originality/value As a community, the authors need to more effectively reflect on shaping mental models that disconnect remanufacturing from analogies that convey inferior quality and performance associations. Firms can overcome reduced utility perceptions not only by providing discounts, i.e. sharing the economic benefits of remanufacturing, but even more by increasing the warranty, thus sharing remanufacturing’s performance benefit and reducing consumers’ risk, a mechanism widely acknowledged in product diffusion but neglected in remanufacturing so far.

“…Diego-Mas et al (2016) propose a genetic algorithm and neural network–based model to design the appearance of environmentally sustainable products while Tang et al (2016) propose a framework for product design optimization that integrates the design stages in the life-cycle analysis for additive manufacturing in order to minimize the product environmental impact. Finally, Aziz et al (2016) provide a literature review on the use of optimization in design, and more particularly, for upgradable products.…”

Design is a process through which customer needs are transformed into product or service specifications, and then used to develop a model or prototype. The prototype is tested, and modifications are brought to it before the production process starts. Moreover, the design process may be divided into different stages, starting from the definition of the customer needs, going through the conceptual design phase and ending up with the detailed design. In this article, we address the conceptual design phase, where the customer needs are assumed to be known. The proposed approach considers, based on customer needs, primary and secondary design criteria. Each design criterion has a set of predetermined possible values (options) from which the designer may select. Making the best selection of all the design features while satisfying the customer needs in terms of cost, quality (customer preference) and environmental performance is a combinatorial problem and therefore a decision-making framework would be helpful for the designers. In this article, the design criteria are evaluated using fuzzy technique for order preference by similarities to ideal solution based on cost, quality and environmental sustainability. A multiobjective and a single-objective binary programming models are then developed and solved, and their optimal solutions are obtained. The multiobjective solutions provide the decision makers with the possible trade-offs, whereas the single-objective model solution can be used as a final decision-making tool. The proposed approach is implemented in a user-friendly software developed by the authors. A case study is conducted using a baby car seat for which three main and six secondary design criteria are considered. The obtained results show the effectiveness of the approach used.

“…This trend in the railway industry is aligned with the vision of a remanufacturing value chain involving several stakeholders, as outlined in Subsection 2.1. Many authors have built models or tools to define the optimal modular structure of a product to be upgraded [217,16,246,248,158]. Product design for upgradability may also support the diffusion of new Circular Economy business models based on the "product-service system" idea, aiming at selling the product use instead of the physical product and offering product upgradability options to customers throughout the product life-cycle [228,216].…”
