However, the adoption and implementation of SCP initiatives in a supply chain can be a major challenge due to existence of several barriers. Therefore, this work aims to identify and evaluate barriers related to the adoption of SCP initiatives in the supply chain. A total of 15 barriers in adopting SCP initiatives are listed through literature and expert inputs. The listed barriers are then evaluated to determine their relative importance using an Analytical Hierarchy Process (AHP) technique. The usefulness of the proposed work is shown by taking the case example of a plastic manufacturing organization in India. According to the findings, the category of barriers related to 'Government support and policies' was attributed the highest importance among other barriers in adopting SCP initiatives in the supply chain. Overall, the purpose of this work is to aid managers and practitioners through important insights as well as support their decision-making in terms of managing SCP implementation issues in the supply chain, in an effective and efficient manner.

In the proposed methodology, initially, a fault tree diagram is constructed, which includes the probable criteria, and sub-criteria of the green supply chain risks, and later, using the fuzzy AHP approach, these criteria and sub-criteria were prioritized for risk assessment. A total eight risk criteria and thirty sub-criteria were identified based on relevant literature and the experts input. The research findings illustrates that the product recovery risks and process risks criteria possess highest priority and need considerable managerial responsiveness for reducing the green supply chain susceptibility and hence performance improvement. Further, a plastic manufacturer green supply chain case illustrative example is presented to show the real-world applicability of the study. The managerial implications and conclusions are also discussed in the end.

To improvement in overall performance, these factors should be formulated within a structural model to understand interacting relationships among them. In this way, DEMATEL (Decision Making Trial and Evaluation Laboratory) method is proposed for the purpose of this research for visualizing and constructing the interactions between identified factors related to GSC. Total 6 performance focused attributes has been identified and further classified into cause and effect group attributes utilizing DEMAEL method. Study results shows that supplier selection and related issue, governmental rules and regulations comes under cause group and green purchasing, design and operations, ecological benefits and resources management, green image, and green productivity forms effect group.

However, the effectiveness of Green Supply Chain (GSC) is comparatively low, as there has been a substantial amount of risk involved in managing GSC efficiently. In this contribution, therefore, we aim to identify and prioritize/rank the responses of risks in a GSC context. It would be useful for industries to focus on highly ranked responses and formulate strategies to practice them in accordance with their priority for managing the consequences of risks in GSC. The present research seeks to propose a model by using the fuzzy Analytic Hierarchy Process (AHP) and fuzzy Technique for Order Performance by Similarity to Ideal Solution (TOPSIS) methods to prioritize the responses in GSC to manage its risks under the fuzzy environment. The fuzzy AHP is useful in deciding the importance weights of the related GSC risks. While, by using the fuzzy TOPSIS, the priority/ranking of the responses in a successful accomplishment of green initiatives is determined. To illustrate the effectiveness of the proposed model, the GSCM real-world case of an Indian poly-plastic manufacturing company is presented.

Its effect could be delay in order, quality damage or may even loss in business, if managers do not account them on timely. To meet the consequences, therefore, in this paper, we attempt to focus on the operational GSC risk evaluation and management by capturing of uncertainty and evaluating the risks by means of simulation to demonstrate the delay/disturbance consequences of the risk (i.e., the loss in business). This work follows a procedure in which, initially, the various uncertainties have been identified and assessed. Later, a risk evaluation has been followed in which the Monte Carlo Simulation (MCS) results exemplify the delay/disturbance consequence of the risk is carried out. Inputs in this research are taken from a GSCM case example of an Indian poly plastic manufacturing company.

These risks and risk factors have a tendency to disrupt the typical GSC operations, and hence, reduce the success rate. To mitigate the consequences, therefore, a flexible decision modeling which could evaluate the risks in the context of GSC is needed from the industrial viewpoint. The present research work intends to propose a flexible decision model based on combined fuzzy analytic hierarchy process (AHP) and interpretive ranking process (IRP) methodology to evaluate the risks associated with implementation of GSC practices under the fuzzy surroundings. Fuzzy AHP approach estimates the priority or ranking of the identified risks by determining of their relative importance. To analyze the risks ranking obtained through the fuzzy AHP, the methodology of IRP is applied. The methodology of IRP, however, also enables the decision makers to understand the interpretive logic for dominance of one risk over the other for each pair wise comparison. The proposed flexible risk evaluation model is applied to an empirical case of Indian poly plastic manufacturing company. The model proposed in this study offers logical means to understand the significance of different risks in the strategic decision processes. It would help the managers and practitioners to interpret the influence of key strategic actions on the performance and to improve the effectiveness of the processes by building some robust and flexible strategies for managing risks in GSC.

However, the successfulaccomplishment of green supply chain (GSC) production and business activities is relatively difficult dueto involvement of different risks. These risks and their respective sources have a tendency to disturb theGSC functioning, and thereby, decline in the ecological-economic performance. Therefore, identificationof risks and their subsequent analysis in the GSC are very important to know and understand. The presentresearch analyzes the risks relevant to adoption and effective implementation of GSC practices at indus-trial viewpoint. A two-phase research approach has been proposed and used in this study. In the firstphase, six categories of risks and twenty-five specific risks, associated with the GSC, were identified. Thebasis of identification of the risks was literature and inputs received from experts from industries. Experts’opinion has been collected from the officials and managers of four Indian poly product-manufacturingcompanies. In the second phase, the fuzzy analytic hierarchy process (fuzzy AHP), a qualitative and quan-titative analysis was used to analyze the identified risks for determining of their priority of concern. Theused fuzzy AHP approach is also useful in dealing with the human subjectivity and ambiguity involved inthe process of risk analysis. In this research, an effort has been made to know the most important risk inGSC context, and the findings would be useful for industries in managing and reducing the consequencesof the risks in GSC. The analysis of the results indicates that operational category risks are the mostimportant risks in GSC. Sensitivity analysis is also conducted to examine the priority ranking stability.
