The purpose of this paper is to develop a system dynamics model which allows an Original Equipment Manufacturer in the electronics industry to test different value recovery strategies in a Closed-Loop Supply Chain setting. Due to shortening product lifecycles and legislative regulations, companies face the challenge of handling products at their end-of-use or end-of-life. Accordingly, effective...

This paper describes the Contract Expression Language (CEL), currently being developed at the industry consortium Content Reference Forum. The CEL is an XMLbased language designed to express contractual agreements between different parties for the purposes of capturing and communicating contractual information, and facilitating contract execution and enforcement by machines with respect to gran...

While issues such as clean production and energy efficiency are still central in sustainable development discourse, attention is increasingly on patterns of consumption at multiple levels in society. This opens new opportunities and responsibilities for design research, as we shift from a focus on product lifecycles to people’s lifestyles. It also requires further understanding the ‘social sust...

Service information is the information that is required to support the taking of decisions and actions in a service environment. In product-service systems (PSS) this information includes both information to support the lifecycles of physical products and associated services and information to support the management of services. Service blueprinting techniques have been used for visualising and...

Insect pathogens are an excellent source of novel insecticidal agents with proven toxicity. In particular, bacteria from the genera Photorhabdus and Xenorhabdus are proving to be a genomic goldmine, encoding a multitude of insecticidal toxins. Some are highly specific in their target species, whilst others are more generalist, but all are of potential use in crop protection against insect pests...

In this paper we report on an empirical study on requirements engineering of hybrid products. Hybrid products (often also referred to as product service systems) – a combination of product, software and service elements – are an emerging trend on the market. Companies intend to offer holistic solutions for customer problems and not single products. The development of hybrid products differs fro...

This work suggests a multilevel support to software developers, who often lack knowledge and skills on how to proceed to develop secure software. In fact, developing software with such quality is a hard and complex task that involves many additional security-dedicated activities which are usually omitted in traditional software development lifecycles or integrated but not efficiently and approp...

Product service plays an essential role in day-to-day operations of nowadays manufacturing industries. However, the changing demands of the market/customers, the increasing complexity of product functionalities and the extended product lifecycles present challenges to related In-Service projects. In order to handle the increasing number of projects and to control the costs and resource consumpt...

Supplying integrated data model with multiple structures for addressing diverse requirements from different production lifecycles and control levels is the natural development of automation systems. Data processing, presentation and manipulation require well-designed computation model that consists of interrelated groups of function components or applications that can be realized in the form of...
