Abstract: In this paper it is shown the value of embedding the 1st (B) and 2nd (C) Erlang formulae in the superstructure of the M/M/r/r+d model to obtain a number of relations whose derivates in the number of servers, r, in the number of waiting positions, d, and in the intensity of traffic, as well as in arrival and service rates and offered load, can be evaluated. These derivatives are very useful in the optimal design of teletraffic as well as manufacturing and service industry congestion systems. The paper also deals with a concept of continuing engineering and management education (CEME), which essentially involves 'transfer of current research work' and 'the teaching and development of targeted courses to industrial needs'. It is stressed that stochastics in CEME, although difficult to implement, among other advantages, allow us to expand the scope of our postgraduate instruction and to enlarge the dissemination of our 'knowledge creation'.
