| Abstract: | Corresponding to stochastic variable, it is a better choice to describe the market demand uncertainty of innovative products
with fuzzy variable because no historical data is available. Traditionally, possibility measure is regarded as the parallel
concept of probability measure. However, it is, in fact, the credibility measure that plays the role of probability measure!
Based on the credibility theory, this paper studies how to evaluate the safety stock of enterprise given desired product availability
when the node enterprise market demand of supply chain is described by Gauss fuzzy variable. Thereinafter, the authors discuss
the impact of required product availability and demand uncertainty on safety stock, compare the correlative issues with stochastic
demand, and get some useful results. |
