Modelling Sustainability Performance in Manufacturing Companies

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Nowadays, organisations need to operate with economic, social and environmental goals in mind. Indices objectively quantify such goals; hence, an organisation can develop and compare policies based on future index values. We propose a system dynamics‐based model of a manufacturing company that frames its operations in terms of a set of easily ...
