Research On The Information Tracking System Of Retired Construction Machinery Product

The remanufacturing of retired engineering machinery products had been developed into a new industry recent years gradually. The remanufacturing industry played a prominent role in relaxing the gradually severe pressure on environment resources and it had an important significance for the developing of circular economy. The retrospective study on the information of retired product was not only significant, but also necessary for the development of the remanufacturing industry. However, in the process of traceability information of engineering machinery retired product, there were the problems of affect traceability chain established such as the traceability relationship was unknown, the information was scattered and deficiency. Therefore, with different modes about the retired engineering machinery products, the corresponding traceability information chain was also different, there were the characteristic of difficult and diverse in the process of traceability information. So it was necessary to research on the retrospective mechanism. The main research contented the following parts.(1)Based on the current domestic and foreign research on the division of the remanufacturing mode, the article took the large hydraulic excavator for example. From perspective of three remanufacturing mode, it studied the retired engineering machinery products and constructs the main frame of retired engineering machinery products, it analyzed the remanufacturing characteristics of each remanufacturing and created the corresponding information model, at last it finished building the retired product information retrospective model.(2)By the analysis and researching on two models of remanufacturing:original equipment manufacturer and manufacture union, the article studied the information retrospective rules of remanufacturing procedure. OEM mode surrounded the supply chain management in product information traceability system, the research on OEM based on the detailed analyzed the business processes and established the various stages of decommissioning product information model, and it established information retrospective model diagram of engineering retired machine. And the related research was focused on remanufacturing information sharing mechanism between enterprises and the constraint evaluation model by the method of AHP, which to calculate the evaluation index weight of information sharing. Then it used the fuzzy comprehensive evaluation method to establish expert evaluation model, and by issuing questionnaires to collect data validation evaluation rationality and applicability of the model.(3) The article focused on the functional design and achievement for the independent third party database of the independent third party remanufacturing mode. The related data was obtained through the approach of "reverse engineering", the article analyzed the requirement of the information system and function design, and at last it developed the traceability information system based on B/S.Through the study on the information traceability of the three remanufacturing modes about the engineering retired machines, the achievement of the research had a contribution to the development of whole remanufacturing industry for engineering machinery retired products.
