Abstract
With the expansion of the study about green logistics, sustainable supply chain management (SSCM) has appeared as a new concept in current economic circumstance. This paper studies the sustainability optimization of enterprise logistics network from a strategic perspective and proposes a multiobjective sustainable logistics optimization model considering three dimensions of sustainability: economy, environment, and society. In this model, the environment factor was measured with a Life Cycle Assessment (LCA) method based on Chinese Life Cycle Database (CLCD), while for social factors, Sustainability Reporting Guidelines (GRI) are utilized to quantify the social performance. Moreover, the model was solved with an adapted version of the ε-constraint method named augment constraint algorithm (AUGMENCON) through GAMS software. The numerical experiment results of a computer manufacturer supply chain show that the proposed model is able to integrate all dimensions of sustainability and simultaneously prove the capability of AUGMENCON in providing a set of trade-off solutions for the decision makers to make different decisions under different environment and social requirements.
Highlights
Sustainable supply chain management (SSCM) has been an increasingly important topic in the field of sustainability and supply chain management (SCM)
The sustainability optimization of enterprise logistics network is studied from the strategic perspective, and we mainly solved the following problems: (i) A multiobjective optimization model for logistics network considering three dimensions of sustainability is proposed
(ii) The measurement of environment impact is realized through an Life Cycle Assessment (LCA) method based on Chinese Life Cycle Database (CLCD), which is implemented through eBalance software
Summary
Sustainable supply chain management (SSCM) has been an increasingly important topic in the field of sustainability and supply chain management (SCM). Carter and Rogers [1] define SSCM as the strategic, transparent integration and achievement of an organization’s social, environmental, and economic goals in the systemic coordination of key interorganizational business processes for improving the long-term economic performance of the individual company and its supply chains. Nowadays, requirements from both government and customers urge enterprises to concern environmental protection and assume more social responsibility. This paper studies the logistics network optimization problem from the perspective of sustainability development and correspondingly proposes a multiobjective model.
