The Impact

Consumers of electronic products (e-products) increasingly purchase new product and dispose of the last-generation of fully functional product for the sake of newer models with added functionality brought on by advances in technology. This consumer behavior is referred to as technological obsolescence, rendering older versions of the product obsolete and creating e-waste. The phenomenon of technological product obsolescence and e-waste is especially prevalent in electronic products such as cell phones and video games. E-waste is very costly for the environment, as well as for electronics product manufacturers. This paper investigates the use of a Product Service System (PSS) based model to design obsolescence resistance product, hence mitigating the impact of e-waste. The approach is derived from the results of an empirical study of multiple high e-waste generating products. As part of the study, various products are analyzed and guidelines for designs are derived from the empirical data. The utility of the proposed approach is demonstrated via the conceptual design of a novel smart phone based on the PSS framework.

The Impact

AbstractWe study a DevOps software development process for a Product-Service System (PSS) using a design structure matrix (DSM) representation. We find unique features such as nested, planned iterations at differing rates which are not evident in conventional engineering development projects. We describe the impact of integrating ongoing operations into a development process and identify some of the enablers that lead to adoption of a DevOps process. We conclude by discussing the implications of our findings and raise questions for further research.

Design Factors

In competitive market environments, strategies that adding services to products for sales promotion are now moved to integrate products and services for satisfying diverse customer needs, and the number of these cases is gradually increasing. Trends of integrating products and services lead to the emergence of a product-service system (PSS). To implement and embody a PSS solution in new product development, a comprehensive design framework is allowed designers to facilitate the design factors of the PSS in complex business environments. The objective of this paper is to propose a PSS model to identify design factors for developing products and services by integrating object-oriented concepts and blueprinting in context of a business ecosystem. The proposed model is developed based on relationship between products and services matching with their design factors. The products and the services are then brought together to form a PSS. Functions and processes can be categorized to identify the design factors in different levels using the object-oriented concepts. Interaction between products and services lies on a PSS platform to form a product service system in blueprinting. To demonstrate of the effectiveness of the proposed model, we use a case study involving a smart phone.

System Context

Static structural aeroengine components are typically designed for full lifetime operation. Under this assumption, efforts to reduce weight in order to improve the performance result in structural designs that necessitate proven yet expensive manufacturing solutions to ensure high reliability. However, rapid developments in fabrication technologies such as additive manufacturing may offer viable alternatives for manufacturing and/or repair, in which case different component lifing decisions may be preferable. The research presented in this paper proposes a value-maximizing design framework that models and optimizes component lifing decisions in an aeroengine product–service system context by considering manufacturing and maintenance alternatives. To that end, a lifecycle cost model is developed as a proxy of value creation. Component lifing decisions are made to minimize net present value of lifecycle costs. The impact of manufacturing (represented by associated intial defects) and maintenance strategies (repair and/or replace) on lifing design decisions is quantified by means of failure models whose output is an input to the lifecycle cost model. It is shown that, under different conditions, it may not be prudent to design for full life but rather accept shorter life and then repair or replace the component. This is especially evident if volumetric effects on low cycle fatigue life are taken into account. It is possible that failure rates based on legacy engines do not translate necessarily to weight-optimized components. Such an analysis can play a significant supporting role in engine component design in a product–service system context.
