ANALYSIS OF THE ECONOMIC AND ENVIRONMENTAL PERFORMANCE OF DUAL SOURCING BASED ON A SINGLE-PERIOD INVENTORY MODEL
Traditionally supply chain management decisions are based on the economic performance of the involved parties which can be expressed by financial and non-financial measures, such as costs or profit and customer service. Recently, also the environmental performance has become more important for companies due to environmental regulations imposed by authorities and due to customer pressure. Based on that, companies have to reconsider and re-evaluate strategies, such as outsourcing and offshoring, and must search for new supply chain strategies that are at the same time cost-efficient and environmentally friendly. One possibility in this respect is to use dual sourcing instead of single offshore sourcing. In order to analyse the impact of dual sourcing on the economic and environmental performance of a company, we develop a single-period dual sourcing model based on the newsvendor framework. It turns out that dual sourcing helps to reduce the transport carbon emissions while improving economic performance of the company. Further, we investigate how regulations on transport (carbon emission taxes or emission trading for transport) affect the decisionmaking and the performance of the company. The environmental performance can be further improved when regulations are imposed, whereby the impact on the expected profit can be positive or negative depending on the regulatory measure.
