Evaluation of methods used for life-cycle assessments in discrete event simulation

The incitements from society for life-cycle assessment (LCA) and credible ecolables are ever-increasing often important for successful marketing of products. Robust assessment methods are important for, useful and trustworthy LCAs and ecolables. In order to improve the metrics of a product’s, is it important to fully understand its production system. Discrete Event Simulation (DES) are able to provide more detailed information than traditional LCA approaches. Therefore, used to combining LCA in DES have been developed during the last decade. The combined have matured and the experiences grown. This article compares six previous cases and aims to and discuss their experiences to aid future development. The results show where it is important to make good decisions throughout the modeling methodology, for example goal scope definition, trustworthy input data for sensitive parts, and communicable impact categories.
