Abstract

The implementation of sustainability principles is becoming fundamental for companies, also for creating added value in the production processes. Production managers should not consider only the economic-financial aspects in their decisions, but also the environmental and social implications to extend the benefits to all current and future world populations. This vision requires to develop and apply sustainability-oriented methodologies to compare alternative production strategies. This paper contributes to addressing this problem by proposing a methodology that allows comparing different production strategies by considering their sustainable impact, starting with the definition of their processes. An aggregated sustainability index has been designed for this purpose. Thus, the paper contributes to the literature on the evaluation of sustainability through the development of a methodology, which can be used by the practitioners as a decision support tool to identify the most sustainable production strategy according to the objective of the company and the specific production process considered. Then, the proposed methodology has been applied to compare two different production strategies, i. e., AM-based remanufacturing and the production of new components. A simulation model has been implemented to reproduce the behaviour of the two competing production strategies. Although the results depend on the utilized data, this application showed that it is possible to distinguish different areas of convenience for each strategy. Moreover, findings revealed that the sustainability of the production strategies is strictly connected to the adopted technology and the importance given to the economic, environmental and social aspects by the company.
