RELIABILITY ALLOCATION WITH OR WITHOUT COST CONSIDERATION

摘要

In this paper, a new approach based on the effort minimization algorithm and disjointproducts algorithm is derived. Different cost functions containing parameters can be applied to work with the concept of "choice factors". Even so, the cost factor may not take into account as a function if such data is not available. The choice factor is defined as the ratio of rate of increase of effort to reliability importance for each component. The derived effort minimization algorithm can also be applied to any system structure that has identical or non-identical components. The results show that this algorithm can be a simple and efficient tool for aiding reliability engineers during the design phase of a product.
