“…Due to specific system construction and specific process procedure it seems to us that another than common methods are to be applied. Following session is the example of such approach [1,2]. The assessment of real operation profile impact on system failure is the difference from previous approaches.…”

“…The goal of this paper is also to verify the suggested solution in relation to some functional elements which might be influenced by the mission profile. Since the system fulfils a required function in a very specific manner we focus on the mission profile impact [1,2].…”

Complex mechatronic systems sometimes do work in difficult and adverse environment. Such environment may affect the system’s performance and also dependability characteristics. Since we use complex systems with one shot items we need to know basic characteristics of such a system. The paper deals with advanced mathematical methods used for field data assessment in order to prove presumed impact of mission profile and system real operation profile onto system reliability. Thank to the collected data set it is assumed that operation of the system is actually a kind of time series. The paper presents identification of the time series model, its parameters´ estimation and prediction of system characteristics – like reliability/survivability function of the system for instance. Since the model of the time series has not been known, correlations with other system can be further determined and mission duration estimated. This estimation helps to organize support and operation of the system.
