A Study On Decision And Monitoring Of Supply Chain Based On Multi-stage Carbon Footprint

"Low carbon" has become a hot word with universal response ever sinceCopenhagen Climate Conference. Many world-class companies have found out thatboth cost and carbon emission can be reduced from supply chain. They voluntarilycontrolled the carbon footprint in supply chain and took on the responsibility of thesupply chain management of quantifying carbon footprint. They formed "SupplyChain Leadership Alliance coalition” to put pressure on its suppliers to require themto announce their carbon emissions data and "carbon footprint" verification. On theother hand, the consumer preference for low-carbon products is increasing. How tomeasure, reduce and monitor the supply chain carbon and promote low-carboncompetitiveness of enterprises in supply chain have been big challenges to them.Therefore, study of multi-stage supply chain decision-making and monitoring is veryuseful to help to clearly recognize the nature of the multi-stage supply chain carbonfootprint, to explore the motives of reducing carbon cooperatively hidden behind theinputs of the cost and benefit and to monitor multi-stage supply chain carbonfootprint.The main contents are as follows:(1) Construct third-stage supply chain carbon footprint structure model andcalculation modelThe paper firstly defines the concept of Multi-stage supply chain carbonfootprint and constructs the structure model and calculation model of Three-stagesupply chain carbon footprint. Then this paper studies the supply chain carbonfootprint of31manufacturing enterprises within nine manufacturing industries in thisin The Pearl River Delta. Finally, this paper presents a number of measures andproposals aiming at lessening the multi-stage carbon footprint of the supply chain.(2) Build up investment decision models of supply chain multi-carbon footprintreduction based on the evolutionary gameFirstly this paper builds up the evolutionary game model of the supplier and themanufacturer, concerning of the main bodies of supply chain multi-carbon footprintmanagement, the supply and the manufacturer and the positive external effect ofsupply chain carbon reduction investment and then finds the evolutionary stablestrategy(ESS). The results show that: the supplier’s and the manufacturer’s carbonemission reduction investment strategies are closely related to their carbon emissionreduction input-output ratio. When they range from different area, there’ll be different ESS. Therefore, the paper also analyzes the evolution results under supply chaincontract with punishment mechanism and the government intervention.Thirdly thepaper makes a confirmation of influence made by different factors to ESS of thissystem with real operating data in survey and calculates effective penalty undersupply chain contract mechanism and carbon emissions trading price to promoteinvestment of carbon reduction of the enterprises of the supply chain in survey。(3) Establish a multi-stage supply chain carbon footprint monitoring systembased on multi-stage carbon footprintFirstly, a multi-stage carbon footprint catastrophe prediction model is establishedbased on the grey calamity theory and is confirmed by real operating data in survey.And then the multi-stage supply chain carbon footprint monitoring system is built upcontaining process model and control model，using of process control theory. Finallythe monitoring system is applied to the carbon monitoring of actual operatingactivities in supply chains.
