Titre : CircuSchain: A continuous improvement method for evaluating and designing supply chains based on circular economy principles Auteurs : Asiye Kurt, Mario Cortes-Cornax, Agnès Front, Van-Dat Cung, Fabien Mangione, Revue : Open Journal in Information Systems Engineering Numéro : Issue 1 Volume : 5 Date : 2025/06/4 DOI : 10.21494/ISTE.OP.2025.1298 ISSN : 2634-1468 Résumé : The Circular Economy consists in producing goods and services in a sustainable way by limiting the consumption and waste of resources and the production of waste. Pressure from laws, stakeholders and customers leads organization to review their practices and adopt the circular economy principles to improve the circularity of their supply chains. In practice, companies look for a way to make their supply chains more circular. A successful transition towards circular supply chains requires continual measurement of progress towards circularity. The main contribution of this paper is a method called CircuSChain that aims at guiding organizations in order to evaluate and design more circular supply chains. The method, formalized in the form of an intentional process model and a product meta-model, is based on the use of a generic model of circular supply chains, a serious game to simulate the structure and operating of a circular supply chain, and a circularity indicator to calculate the circularity of a supply chain. This paper extends a previous article [KUR 23] by detailing these tools used by the method as well as all the protocols used in the different strategies proposed by the method.
