Small and medium sized enterprises (SMEs) play an important role in any economy as they contribute to GDP and employment. However, sustainability (right combination of economic, environmental and social) of SMEs is a major concern as they prioritise economic performance over environmental and social to remain competitive. Majority of prior research...

The advancement of sustainability trajectories is a critical challenge for most of small and medium-sized enterprises (SMEs). SMEs require specific considerations with regard to business methodologies for achieving and enhancing sustainability, since their business case is far from similar to larger counterparts. As a consequence, tools for impleme...

Minimizing a company’s operational risk by optimizing the performance of the manufacturing and distribution supply chain is a complex task that involves multiple elements, each with their own supply line constraints. Traditional approaches to optimization often assume determinism as the underlying principle. However, this paper, adopting an entropy...
