The Reparability Function: Further Steps toward the Science of Reliability

This research has multiple goals. As first I calculate the ability of working (= effectiveness) of systems and their resistance to repairs (= reparability) that are systemic features often treated in qualitative terms. I suggest the use of the Boltzmann-like entropy to derive the reparability function that relates the above mentioned properties exhibited in parallel by a system during the whole lifespan. This paper pursues a second scope. The theory of reliability has not yet progressed as a science since most of the researches are grounded upon pure statistical models. Inductive-experimental approaches are more popular than deductiverational approaches. Instead the present research derives the behavior of a system on the basis of ‘physical’ modeling and proves to be in line with the style typical of mature disciplines.
