According to the basic concept of multistate system, the eigenvalue and evaluating index of strongly coherent multistate system(SCMS) are discussed.The reliability expression of series and parallel SCMS is offered. By introducing the evaluating index, such as s expected performance utility level, variance of s expected performance utility level and usable life index and so on, the method of dynamic reliability analysis and quantitive evaluation of SCMS is put forward in the process of comparing competing system. Through an example of a series system,its analytical method is presented of foreseting and evaluating system reliability.It can be used as reference to the reliability evaluation and analysis of complicated system.
