A bilevel programming model for corporate social responsibility collaboration in sustainable supply chain management
نویسنده
چکیده
This study proposes a bilevel programming model in which the supply chain (SC) director determines optimal performance levels of corporate social responsibility (CSR) and compensation for all SC actors, thus maximizing total SC profits. Given the fixed CSR performance levels, the equilibrium product flows are determined in the lower-level model, in which the profit-maximizing behavior of the individual SC actor is considered and formulated as a variational inequality. The test results show that it is possible to improve not only performance of CSR, but also the profits of both individual SC actors and the whole SC through proper SC collaboration. 2014 Elsevier Ltd.
