Research On Some Key Problems Of Vulnerability In Manufacturing Supply Chain

With the development of economic globalization and constantly fine of socialdivision of labor, manufacturing was facing pressures and challenges from variousaspects, as it won many development opportunities at the same time. In the fiercecompetitive environment, many enterprises united with each other to organize theproduction and participate in the competition in the form of supply chain. Practice hadproved, this way of production and competition was conducive to the development ofthe specialization of production and the rise of a wider range of cooperation. Therefore,the research content about the supply chain had been brought to the attention of thebusiness community and academia.However, with the expanding of geographical scope and field of cooperation, thesize of the supply chain system was also gradually expanding, which increased theprobability that the supply chain was influenced by internal, external, and many otherfactors to a certain extent, bring serious impacts to normal production of supply chain,and made the supply chain reveal a certain vulnerability. With the appearance of allsorts of surprises of supply chain, the issues of vulnerability in supply chain causedextensive concern of the business community and academia.On the basis of the analysis of the actual situation and related research field statusquo of manufacturing supply chain, this paper put forward the different analysis angelsof the vulnerability in supply chain, established a targeted analysis model, and designedthe quantifiable analysis methods, which put forward a new research idea for researchof the vulnerability in supply chain. The main research content of this paper is asfollows:①Through the analysis and summarization of supply chain and its vulnerability inwhich both different scholars and research institutions at home and abroad study, therelated concept of supply chain, system vulnerability and the vulnerability inmanufacturing supply chain were cleared firstly. On this basis, the influence factors ofmanufacturing supply were analyzed, and the manufacturing supply chain riskenvironment and risk structure were specified, which laid foundation for the analysis ofthe vulnerability manufacturing supply chain’s influence factors.②On the basis of the research status and practical problems of the vulnerability inmanufacturing supply chain, the author put forward the clear thesis topic, then designed the detailed research thinking and guided the paper to launch a series of studies. Then,the overall framework of this paper was set up, which designed the research contents ofthe vulnerability in manufacturing supply chain based on three different perspective, putforward the topology network analysis to improve the weighted network nodecontraction method, R-A-WNN supplier quality evaluation and the analysis of thesupplier collaborative efficiency based on the immune clone algorithm. In the light ofthe characteristics of each specific question,these three methods considered theimportant influence part on calculation of the production，in order to make the resultmore accord with objective reality.③The topology of network organization in manufacturing supply chain wasresearched, and a weighted analysis model about the node importance was builtaccording to topology of the manufacturing supply chain. In the model, the importancedegree of network structure of the supply chain topology nodes was analyzed by nodecontraction method. Then, through the analysis of the change degree of supply chainnetwork topology condensation before and after the node contraction, the structuralimportance of a node could be quantified. In order to make the calculation result accordwith objective reality, a calculation method for the analysis of the interaction betweenthe supply units was proposed in the model, which transformed the weighting of nodesinto the impact on the surrounding environment of the node. Finally, an example wasused to verify the validity of the research methods.④Supplier quality evaluation model of manufacturing supply chain wereresearched. Firstly, the influence factors of suppliers and their quality were analyzed,and preliminary evaluation index set of supplier quality was designed; Secondly, aimedat the difference of index evaluation’s standard and index’s character, a hybridquantitative method was put forward; And then, the basic network model of the supplierquality evaluation based on wavelet neural network (WNN) was built, whose networkparameters were also synchronously optimized by the use of ant colony algorithmmodel(ACO); Finally, the feasibility and practicality of this evaluation model wereverified through an application example.⑤Supply chain vulnerability analysis model based on collaborative efficiency inmanufacturing supply chain were researched. Based on the analysis and research ofsupply chain collaborative problem, organization structure characteristics andparticipation subject characteristics of manufacturing supply chain collaboration weresummarized, and then the organization model of multi-layer structure was constructed; What’s more, interaction effect between subject and object and complexity ofproduction object in the supply chain manufacturing process were further detailingresearched, and measures of interaction effect between subject and object, calculation ofproduction object’s complexity were given. On this basis, analysis model ofcollaborative efficiency in manufacturing supply chain was built, and in order to solve it,an improved immune clone algorithm was designed.
