Closed-loop Supply Chains Based on By-Product Exchange

This paper emphasized on the by-products of closed-loop supply chain (CLSC) system. The cooperation processing based on by-products exchange in CLSC is discussed with the decision-making criterion of eco-efficiency maximization. Accordingly, a pricing model is given. The sustainability of the CLSC system is discussed under the circumstances of exergoeconomics. The metric of "system negative environment effect" is introduced to measure CLSC system performance. A case study of Guangxi Guitang Group in China is analyzed at last, which shows the multi-win brought by closed-loop supply chain management (CLSCM)

Decision theory in sustainable supply chain management: a literature review

Purpose – This study aims to aid theory building, the use of decision theory (DT) concepts in sustainable supply chain management (SSCM) research is examined. Design/methodology/approach – An abductive approach considers two DT concepts, Snowden’s Cynefin framework for sense-making and Keeney’s value-focussed decision analysis, in a systematic literature review of 160 peer-reviewed papers in English. Findings – Around 60 per cent of the papers on decision-making in SSCM come from operational research (OR), which makes explicit use of DT. These are almost all normative and rationalist and focussed on structured decision contexts. Some exceptions seek to address unstructured decision contexts via Complex Adaptive Systems or Soft Systems Methodology. Meanwhile, a second set, around 16 per cent, comes from business ethics and are empirical, behavioural decision research. Although this set does not explicitly refer to DT, the empirical evidence here supports Keeney’s value-focussed analysis. Research limitations/implications – There is potential for theory building in SSCM using DT, but the research only addresses SSCM research (including corporate responsibility and ethics) and not DT in SCM or wider sustainable development research. Practical implications – Use of particular decision analysis methods for SSCM may be improved by better understanding different decision contexts. Social implications – The research shows potential synthesis with ethical DT absent from DT and SCM research. Originality/value – Empirical behavioural decision analysis for SSCM is considered alongside normative, rational analysis for the first time. Value-focussed DT appears useful for unstructured decision contexts found in SSCM. Originality/value – Empirical, behavioural decision analysis for SSCM is considered alongside normative rational analysis for the first time. Value-focussed DT appears useful for unstructured decision contexts found in SSCM

不确定需求下有价差时再造回收模式研究

当前,再制造作为一种环保节约型的生产理念和制造方式受到了许多国家的重视,成为实现可持续发展最为有效的途径之一。本文应用博弈理论,针对市场需求不确定情况下制造商废旧产品回收模式选择问题,构建了新品和再造品有价差情况下制造商和零售商的决策模型。研究表明,尽管新品与再造品有价差时,顾客对两种产品的需求存在差异,但企业再造品供给不影响其新品定价。同时,在再造闭环供应链中,制造商的收益受回收成本影响,若各种回收模式回收成本相同,制造商应选择自己回收或零售商回收,这两种模式对产品销售和制造商收益没有影响,且有利于再造品销售,而第三方回收模式较利于新品销售;若各种回收模式的回收成本有差异,制造商应尽量选择回收成本较低的回收模式

Enhancement of Industrial Energy Efficiency and Sustainability

Industrial energy efficiency has been recognized as a major contributor, in the broader set of industrial resources, to improved sustainability and circular economy. Nevertheless, the uptake of energy efficiency measures and practices is still quite low, due to the existence of several barriers. Research has broadly discussed them, together with their drivers. More recently, many researchers have highlighted the existence of several benefits, beyond mere energy savings, stemming from the adoption of such measures, for several stakeholders involved in the value chain of energy efficiency solutions. Nevertheless, a deep understanding of the relationships between the use of the energy resource and other resources in industry, together with the most important factors for the uptake of such measures—also in light of the implications on the industrial operations—is still lacking. However, such understanding could further stimulate the adoption of solutions for improved industrial energy efficiency and sustainability
