The Research On Performance Of Supply Chain And Its Improvements In Aeronautic Weapon Manufacturing

Aeronautic weapon, taking airplane for example, is a special high-tech commodity on the demand of war. Aeronautic weapon is characterized by a long-period researching cycle, big investment, high risk, vast research units involved, uncertain environment and extensive influencing factors and so on. During the process of manufacturing, the supply chain is like a community which consists of numbers of enterprises closely connected to aeronautic weapon manufacturing and shares mutual benefits.In China, there are major problems existing in the supply chain of the aeronautic weapon manufacturing, including low enthusiasm in the market development, lack of innovation spirit, lack of an efficient restriction, lack of incentive mechanism and evaluation system to evaluate management and performance. In aeronautic weapon production manufacturing, there are several pairs of conflicts between investment and efficiency, partial interests and overall interests, scientific research and manufacturing, type and pre-research, innovation and tracking, and between results and conversion. We have neglected to make an overall plan from the point of view that aeronautic weapon's supply chain should achieve the goal of shortening the cycles in making orders and of realizing the benefits of all groups.The improvemen(?) of the performance in the supply chain is inevitably crucial to enhance competitive power in aeronautic weapon manufacturing. The basic measure to deal with the problems mentioned above is to evaluate supply chain and its performance systematically and objectively from the angle of treating the aeronautic weapon supply chain as a whole operating mechanism. And then specific managing methods to improve the performance of the supply chain are expected to be found, so as to sustain the improvement of the aeronautic weapon manufacturing's supply chain.In this essay, by using the theory of system dynamics and its analytic procedure, the performance of the supply chain in the aeronautic weapon manufacturing is evaluated and certain management policies are brought forward. The research contents are as follows:1. Through the theoretical analysis and practical investigation, the formation mechanism and operating mechanism of the supply chain in the aeronautic weapon manufacturing is thoroughly studied. Based on such a research, theories on the operating mechanism of the supply chain in aeronautic weapon manufacturing are generalized.2. Innovational research about assessment methods is done, and the dynamic assessment method based on the theory of system dynamics is put forward. By analyzing the classification of the evaluation index in evaluation index system, concepts such as target variables, conduct variables and correlation variables are promoted in performance evaluation. And the performance evaluation index system in aeronautic weapon manufacturing is established.3. Based on dynamic feedback complexity analysis technology in the system dynamics and the rate-variable fundamental in-tree modeling method, the evaluation index model which is based on the rate-variable fundamental in-tree modeling method is built up and the analysis of the structure model of the evaluation index system is done by the analysis technology of X-0-1 determinant feedback fundamental modeling and branch vector determinant feedback loop.4. Study is done on the simulation of the modified strategy in the supply chain of the aeronautic weapon manufacturing. On the base of the simulation technology, the performance of the supply chain in aeronautic weapon manufacturing and actual cases of the management strategy will be deeply examined. By studying the simulation of the model, the system behaviour of performance evaluation in the supply chain of aeronautic weapon manufacturing is analyzed quantitatively.Major innovation points are included:1. Through the analysis on the formation mechanism and operating mechanism of the supply chain in the aeronautic weapon manufacturing, theories on the operating mechanism of the supply chain in aeronautic weapon manufacturing are generalized. Based on the theory of system science, this research attempts to establish multi-subject and multi-subsystem performance evaluation which aims to evaluate each link in the supply chain, such as main engine plants, arms industry department and contractors who supply spare parts, and to promote concepts such as target variables, conduct variables and correalation variables in performance evaluation. In the meanwhile, the performance evaluation index system in the aeronautic weapon manufacturing is established.2. The rate-variable fundamental in-tree modeling in the supply chain of the aeronautic weapon manufacturing is formed. And the operating system in the supply chain of the aeronautic weapon manufacturing is also constructed, so do the 14 flow digits and 14 differential equation sets in the performance evaluation system. Thus the mathematical description of the supply chain in the aeronautic weap(?)n manufacturing is realized.3. Balanced Scorecard will be used to evaluate performance in multi-angle perspectives. When the evaluation index system is set up, several issues should be involved, which include the decomposition of the overall goal in the supply chain, of main actions taken to realize the goal and of subjects' behaviour and goals in supply chain. By analyzing behaviour and goals of subjects and ways to achieve the overall goal, evaluation index system is expected to come into being. By using such a method, old evaluation measures could be pale in comparison, because it won't able to effectively point out disadvantages that happens when evaluation indexes interact with each other. Moreover, this research is expected to pave the way for establishing the system dynamics model and simulating equation in evaluation index system.4. Analyses on the causes of the overall performance in the supply chain of the aeronautic weapon manufacturing are brought up and related improvements are proposed.
