Network Optimization Design And Analysis Problems For Green Sustainable Operation Management

The global environmental crisis and the pressure of industrial transformation are profoundly affecting the sustainable development of modern enterprises.Operation management is the critical link of the core competitiveness of an enterprise,which determines the profitability and development of an enterprise.The network structure of different levels is an essential carrier for enterprises to implement operation management.In the process of the operation management,it has become a significant challenge for enterprises to build all-round green and sustainable competitiveness by employing the approaches of the network optimization design and analysis when taking into account the development demands of the economy,environment,and society.In the existing literature,few studies focus on the comprehensive schema of network optimization design and analysis from the perspective of green and sustainable operation management.Based on the background of green sustainable operation management,this thesis takes network optimization design and analysis as the mainline,and integrates the mathematical modeling optimization,social network analysis,and decision support system design to support the operational level,tactical level and strategical level of the network problems.The main research contents and achievements of this thesis include the following five aspects:?1?The green sustainable operation management oriented the"IE³ green house"theoretical system framework including theoretical basis,research perspectives,and research level is proposed to establish the multi-level network optimization design and analysis.The framework supports the research of the multi-level network optimization design and analysis.?2?The operational level research of the"IE³ green house"is studied by taking the closed-loop supply chain network as an example.In this study,the optimization design model of the closed-loop supply chain network including the uncertainty environment of forward and reverse logistics is constructed.The dual optimization objectives of minimizing operation costs and minimizing CO₂ emissions are proposed.The weight method and Lagrange relaxation algorithm are used to solve the proposed model.The results of numerical experiments provide management enlightenments for the closed-loop supply chain operation in an uncertain environment.?3?The tactical level research of the"IE³ green house"is carried out by employing the example of an industrial symbiosis network.In this study,the core activity,by-product reprocessing and exchange,is introduced to an optimization model of the industrial symbiotic network.The optimization objectives of minimizing operating costs,minimizing the residual amount of by-products and maximizing social employment opportunities are formulated.The Epsilon method is used to solve the multi-objective optimization model.The results of the numerical experiments provide management enlightenments for enterprises to improve the level of comprehensive utilization of resources under industrial symbiosis.?4?The strategical level research of the"IE³ green house"is proposed with the example of the green innovation cooperation network.This study collects the data of green transportation joint patent applications online,generates a green technology innovation cooperation network with enterprises,research institutions,universities,and individuals as entity nodes,and analyzes the network evolution,network structure characteristics,and cooperative leadership types.The experimental results provide suggestions for enterprises to participate in green innovation cooperation and improve the performance of green technology innovation cooperation.?5?The integration research of the"IE³ green house"is established with the example of the conceptual design for the decision support system.Through the system function description,system architecture construction and application scenarios interface design,the integration of the"IE³ green house"involved in the closed-loop chain network optimization design,industrial symbiosis network optimization design,and green innovation cooperation network analysis.The experimental results provide an information solution for enterprises to carry out multi-level network optimization design and analysis for green sustainable operation management.Taking the network as the mainline,this thesis respectively carries out the theoretical framework construction,closed-loop supply chain network design,industrial symbiosis network design,green innovation cooperation network analysis and conceptual design of decision support system under the background of green sustainable operation.Furthermore,these studies expanded in terms of uncertain environments,by-product reprocessing and exchange,and patent data collection.Through the deployment of a series of network research,this thesis studies the green sustainable practices at different levels of operation management,such as intra-enterprises,inter-enterprises and enterprise groups,and provides integrated solutions for enterprises to build comprehensive competitiveness for green sustainable operation management.
