Abstract

Modern supply chains security solutions need to also solve transport security. Greenhouse gas (GHG) emissions have a direct influence on the structure and behaviour of supply chains. The more complex the supply chains, the more critical these two dimensions become. This paper introduces a mathematical model for computing the risk associated with Greenhouse emissions, within the (SCN) context. The supply model chosen is a two-stage SCN, called the Secure & Green Supply Chain Network (SGSCN). In the SGSCN a Manufacturer is directly connected to several Distribution Centres, each of them connected to one or more Customers. The objective of SGSCN is to minimize transportation costs whilst also maintaining a specified overall security level, including a specified GHG level. The applicability of the proposed model for several supply chain configurations and scenarios is illustrated and discussed.
