摘要：In this paper we analyze a modified model for the so-called PLC – Product Life Cycle, the original model being proposed by N. Al. Pop (2000). This PLC is considered here from a reliability theory viewpoint: our modification lies in the fact that the PLC - curve is transformed in a probability density function which allows the application of statistical inferential procedures.
