摘　　要： 本文旨在提出以模糊集合论研究贸易中的价格问题的新方法.文中提出并讨论了标准模糊价格、一个模糊价格在λ-水平的弹性与确定度、模糊成交价以及模糊成交价的期待值等概念、定理2.1指出,若模糊出价与模糊售价都是标准的,则模糊成交价亦然.定理2.2与定理2.3在模糊成交价与模糊出价及模糊售价之间就弹性与确定度作了比较.定理2.4证明了标准模糊成交价的期待值是唯一的并且稳定的. It is the goal of this paper to present some new methods to investigate the problems in trade through the fuzzy sets theory. The conceptions of standard fuzzy price, elasticity and certainness of a fuzzy price at λ -level, fuzzy price of transaction and its expectant value are discussed. Theorem 2.1 points out that the fuzzy price of transaction will be standard if the fuzzy price quoted and the fuzzy price asking are sc. Theorems 2.2 and 2.3 make some comparisons in elasticity and certainness between fuzzy price of transaction and fuzzy price quoted and fuzzy price asking. Theorem 2.4 proves that the expectant value of a standard fuzzy price of transaction is unigue and stable.
