A systematic literature review to explore traceability and lifecycle relationship

Traceability is the ability to follow a product along its lifecycle. It ensures product safety and quality along the supply chain, managing information generated by several players. Even though regulations establish the information that has to be traced, each player generates much more product (and process) information, which could be used to add value to products, with respect to, not only traceability, but also the lifecycle approach. However, the concepts do not appear to be immediately related in scientific panorama. This paper aims to explore the relationship between traceability and lifecycle through a systematic literature review. Six industries (Software, Manufacturing, Automotive, Automation, Aircraft, and Aerospace) and seven subject areas (Software engineering; System engineering; Industry 4.0; New product development; Process management; Data Management; and Environmental sustainability) were identified through bibliometric analysis. To better explore this relationship in the context of the food industry, a content analysis on lead papers’ sample was performed to identify traceability and lifecycle definitions, methodologies and technologies and their relation. The results of the work, synthetised in a proposed research map, will be of interest to those who are approaching the subject for the first time, and for companies involved in product lifecycle management and food traceability.

Product category rules and environmental product declarations as tools to promote sustainable products: experiences from a case study of furniture production

New requirements and regulations have increased the pressure on companies to provide information on their products. This is challenging for small- and medium-sized enterprises (SMEs) since they lack both expertise and resources. In this paper, the possibilities to develop environmental product declarations (EPDs) for products with use of data-assistant tools are explored. A case study of furniture production in Norway is used to exemplify this. A database with specific environmental data for materials used in furniture has been developed. The database is used to conduct the life cycle assessment (LCA) for selected products and is the backbone of a data-assistance tool used to design and present the EPDs. Five key performance indicators are selected. The database and these KPIs ensures standardised assessments of products that enables both comparison of existing products as well as assessment of environmental performance of redesigned products and potential new products. This paper shows how this enables the SMEs to both provide environmental performance information to stakeholders as well as enables them to identify possible improvements with limited resources and competence on environmental performance and LCAs.

Design of traceability systems for product recall

A product recall is very expensive and a poorly executed recall can be devastating to a company’s reputation. It is, therefore, important to improve the traceability for supply chains to address potential recalls. This paper studies the recall dynamics in a two-stage supply chain with a manufacturer and two suppliers. It is shown that the suppliers would opt-out in improving traceability due to misalignment of incentives, leading to diminishing traceability of the whole supply chain and high product recall liabilities for the manufacturer. To address this problem, this research designs an interest-sharing mechanism by which the recall liability reduction of the manufacturer due to improved traceability can be shared with the suppliers to induce traceability improvement effort. Results show that the interest-sharing mechanism improves not only the economic benefit, but also the traceability for each party. We also provide a systematic framework to choose the design parameters, including the degree of accuracy and level of coding, for the supply chain to realise such benefits.
