Research On Brittleness Management Of Iron And Steel Supply Chain Based On Complex System Theory

The U.S. financial crisis gradually spread worldwide and led Chinese iron and steel enterprises into great trouble. Most of these enterprises have adopted a series of adjustment measures. With the upturn of the global economy, the task for industrialization is once again ahead of Chinese iron and steel companies.The market of the iron and steel industry was hit hard by the global economic crisis. To adapt to the development of the market and maintain the competitiveness of iron and steel enterprises, one feasible way is to conduct research on the supply chain brittleness of the industry and iron industry. Through such research, we can find weak links in the supply chain and make effective prevention in actual management so as to avoid heavy losses.This thesis researches into complex system brittleness of the iron and steel supply chain. It describes the concept and features of brittleness and develops complex system brittleness theory of the iron and steel supply chain based on the complex system theory, complexity of supply chain, brittleness theory of supple chains as well as risk conduction theory. Further, it establishes the brittleness factor system of the supply chain and conducts mechanism research on the origin of complex system brittleness of the iron and steel industry supply chain and through theoretical assumption, it constructs brittleness modal of the iron and steel supply chains. This thesis obtains the following findings and conclusions:(1) Brittleness is an inherent feature of the complex system of the iron and steel supply chain. The existence of brittleness has no relation to the external environment and internal structure of the supply chain. However, the external environment and internal structure of the supply chain are no doubt related to motivation of the complex system brittleness of the iron and steel supply chain. When the complex system brittleness factors of the iron and steel industry are motivated, brittleness events will happen and eventually cause collapse of the whole complex system of the iron and steel supply chain.(2) Through research, this thesis develops the complex system brittleness system of the iron and steel supply chain and constructs the brittleness factor system of the supply chain. It analyzes main elements of 110 iron and steel enterprises and obtains twelve main brittleness factors. The twelve factors are further summarized into six main brittleness events with corresponding main brittleness factors, namely increase in cost pressure, turmoil of external environment, less competitive advantages, deficiency of profitability, deficiency of capital management and weak development potential. Based on the above, it derives the brittleness degree formula.(3) This thesis conducts mechanism research on the origin of the complex system brittleness of the iron and steel supply chain and based on theoretical assumption, it constructs original concept modal. Through test, valuation and amendment of the modal, this thesis eventually obtained the complex system brittleness structure modal of the iron and steel supply chain.(4) This thesis establishes risk prediction modal of the complex system brittleness regarding the iron and steel supply chain. It researches the statistic of the 110 enterprises and develops criteria to divide the main brittleness factors and brittleness risk of iron and steel enterprises. It provides theoretical basis for establishment of brittleness of iron and steel enterprises and can help efficiently prevent the explosion of brittleness and even prevent collapse of iron and steel enterprises.
