Fuzzy multi-objective optimization decision-making of reliability of series system

In many practical situations where reliability enhancement is involved, the decision-making is complicated because of the presence of several mutually conflicting objectives. For example, it is conflicting to reduce the cost of the system and to improve the reliability of the system at the same time. Moreover, in the decision-making of reliability, various kinds of uncertainty, i.e. experts information character, qualitative statements, vagueness, etc. are involved. In the light of these, this work presents a fuzzy multi-objective optimization decision-making method, which can be used for the optimization decisionmaking of the reliability with two or more objectives. An example is given to illustrate the method. Copyright (C) 1996 Elsevier Science Ltd.
