چکیده
|
The presence of undesirable and non-discretionary factors in general multi-stage systems is one of the challenges of evaluating these systems. This challenge is multiplied when these factors are present in the system at the same time. In this article, a new model is presented for evaluating General multi-stage series systems with these factors. The general idea of this model is how to choose the contraction and expansion parameters, Finally the results are examined with a numerical example.
