Research On Several Operations Management Problems In The Remanufacturing Industry Developing Process

With the increasing consideration on advancing Circle Economy,remanufacturing was paid more and more attention as one of main supporttechnologies. Remanufacturing has being in course of industrialization, butin initial phase, and in face of obstacles from respects of society,technology, policy and management etc. Considering the actual states ofChina remanufacturing, this paper researched several operationsmanagement issues which was cared by various aspects from angle of viewof remanufacturing players. Based on need analysis on trend ofdevelopment of China Remanufacturing, six operations management issueswere mainly researched, and there are:(1) risk analysis and assessment ofremanufacturing players,(2) forecasting of recovery quantity ofremanufacturing core and remanufacturing rate,(3) remanufacturingquality management methods and establishment of remanufacturing qualitymanagement system,(4) authentication mode of China remanufacturing,(5) development mode of China remanufacturing industry, and (6) subsidypolicy and performance assessment methods of remanufacturing. The sixissues constituted a regular operation process.(1) Risk analysis and assessment technologies were discussed. At first,the risks in remanufacturing process were recognized as equipment risk,technology risk, management risk manipulation risk and environment risk.Then the weight of risk elements were researched using analyticalhierarchy process based on the establishment of judgment matrixes ofcriterion layer using Delphi method. The research supplies reference to riskmanagement and decision constitution and can be helpful to recognize andevade risks for remanufacturing players.(2) Forecasting technology of recovery quantity of remanufacturingcore was researched. Concepts and assessment methods of remanufacturingrate were advanced and discussed, as well as the forecasting method ofwhich. The support vector machine (SVM) was used in forecasting ofrecovery quantity of remanufacturing core based on advancing of conceptof time sequence space. The result shows that SVM can bring less inaccuracy relative to polynomial and artificial neural network (ANN) inquantity forecasting. Considering the actual states of Chinaremanufacturing, the concepts of remanufacturing rate were put forward,including Quantity Remanufacturing Rate (QRR), Weight RemanufacturingRate (WRR), Value Remanufacturing Rate (VRR), Quantity-ProportionRemanufacturing Rate (QPRR) and Value-Proportion RemanufacturingRate (VPRR), also the application conditions and assessment methods ofthem were discussed. The feasibility of remanufacturing rate forecastingusing Markov Chain was analyzed at last. The researches can be helpful tothe constitution of remanufacturing production planning.(3) Remanufacturing quality management methods was discussed andremanufacturing quality management system was put forward. Firstly, theversions of remanufacturing quality management were discussed based onanalysis of particularity of which. Then SVM was introduced toremanufacturing quality control and result shows well. Theremanufacturing quality management system was established using processmethod based on frame of ISO9000, which includes management process, core process and support process.(4) Authentication mode of China remanufacturing was investigated.Based on the international current eight authentication modes, theauthentication mode of China remanufacturing was advanced, i.e. operationmode adopts form of evaluation by the second side in conjunction withauthentication by the third side, and process mode adopts form of productauthentication in conjunction with system authentication. The base jobs ofremanufacturing authentication was put forward based on analysis onremanufacturing product authentication, remanufacturer qualificationauthentication and management system authentication. Also the productioncontrol and process control of remanufacturing product authentication wasdiscussed. At last, the control requirements were advanced based onanalysis on risk points in different phases of remanufacturing productauthentication, the phases are requisition phase, type approval test phase,practical inspection phase and subsequent supervision phase.(5) Development mode of China remanufacturing industry wasadvanced. In response to development regularity of correlative industry, development mode of China remanufacturing industry was advanced basedon analysis of remanufacturing industry of developed countries anddevelopment phase and trend of China remanufacturing industry. Theconclusion is that China remanufacturing industry should adopt thedevelopment mode of assemble with corresponding manufacturing industryand large-scale. The development suggestions were debated and thenotions of construction of industry development support system werediscussed from seven aspects.(6) Subsidy policy and performance assessment methods ofremanufacturing were discussed. The subsidy policies in two situationswere discussed based on breakeven chart, the profit status and subsidymagnitudes were put forward subsequently. These will be helpful in policyconstitution for correlative departments. Also, the performance assessmentmethods were studied. The integrated assessment indexing system ofremanufacturing was advanced and based on which the applicability ofseveral performance assessment methods in development ofremanufacturing industry were discussed. These provided theoretical basis and operation guide for remanufacturer to develop self-assessment and forthe authorities concerned to evaluate the performance of remanufacturers.Several operations management issues especially cared byremanufacturing players in the course of industrialization of Chinaremanufacturing were studied based on analysis on actual demands andtrend of development. It introduced new thoughts and methods into thedeveloping remanufacturing operations management of Chinaremanufacturing players. It will be helpful for business decision-making,constituting remanufacturing production planning, establishingremanufacturing quality management system, proceeding remanufacturingauthentication, striving for policy support, and performance assessment.The effectivity of these methods was checked by empirical study. It hasscientific and significant application significance and which will promotethe development of remanufacturing operations management, improvequality of remanufacturing product, enhance the competitive power ofremanufacturers, and shorten the development gap of remanufacturingindustry between our country and developed countries.
