Allocation method of the system reliability based on the production cost and maintenance cost

Reliability allocation is the engineering decision problem of the harmony and management between the material resources and human resources, and has correlation with the production cost and maintenance cost, so reliability allocation must consider the production cost and maintenance cost. The paper gives the functional relation formulas of the system reliability and production cost, the system reliability and maintenance cost are presented, establishes the fuzzy optimization allocation model of the system reliability based on the production cost and maintenance cost, and gives the engineering example of the method application. The example shows that the method is scientific and reasonable, and has important value of engineering application.
