Power-law distribution for moral hazards in supply chain

摘要

The objectivity is to obtain the evolution law of moral hazards in supply chain, and to control it effectively. A Multi-Local-World directed networks model according to persons'' interacting rules, is constructed to specify the evolution law of topological of the moral hazards in supply chain. Using the method of complex networks, the topological structure''s evolution law is gotten. The result shown that, the Multi-Local-World directed networks model of supply chain''s moral hazards satisfies power-law distribution, is a scale-free networks, the component is decided by βi, the character of the supply chain.
