Abstract | The paper presents a new method for reliability assessment for complex aging multi-state system under stochastic demand. The system and its components can have different performance levels ranging from perfect functioning to complete failure and, so it is treated as a multi-state system. The system has some components with increasing failure rate. Demand is not constant and is treated as multilevel discrete-state continuous-time stochastic process. Straightforward Markov method applied to solve the problem will require building of the system model with great number of states and solving a corresponding system of differential equations. Lz-transform method, which is used for reliability assessment drastically simplified the solution
