This paper focuses on the scheduled situation assessment of dynamic physical systems to which testing is not applied. First, a set of modeling concepts as to physical system operation is introduced: such concepts stress the importance of the role played by system parameters, which are a number of physical, chemical, dimensional, structural, spatial properties of the physical system at hand. So, situation assessment is defined as the task of determining the current system parameter values of a given physical system. Since parameters are evolving over time owing to wear and tear phenomena, a set of assumptions as to the dynamic evolution of the values of system parameter is discussed. Then, a logical model for the accomplishment of the task of situation assessment is proposed and its cognitive plausibility is proven by means of a case study.
