基于定性模拟的供应链成员企业行为

A Study on Behavior of Supply Chain Entities using Qualitative Simulation

供应链成员企业的行为在外部环境变化和成员企业之间相互作用的影响下,在整体层次上会呈现出一定的规律性和确定性。用定性模拟的方法对供应链成员企业的行为规律进行了研究。结合QSIM算法和因果推理方法,对供应链成员企业行为进行了定性模拟,设计了环境变量和决策变量与成员企业行为之间相互作用的表达方法,给出了定性模拟的模拟规则和模拟机制,得出了不同类型供应链成员企业的行为变化特征。

The change of external environment and the interaction among supply chain entities influence the behavior of supply chain entities. The behavior of the entities presents definite regularity and certainty at holistic level, and is studied by qualitative simulation method. The QSIM arithmetic and causal reasoning is used in qualitative simulation. The representation of the interaction among environment variables, decision variables and entities behavior was developed with the qualitative simulation rule and mechanism. The behavior characteristic of different kinds of entities was obtained by simulation.
