Abstract (EN):
The paper presents a method for the analysis and design of industrial production
systems based on a joint assessment of the cost and the quality of service. The
operation of a production system is seen as the accomplishment of a sequence of
missions, each one corresponding to the cost-effective production and delivery of
a specified quantity of products within a specified time frame. The paper shows
that the probability of successfully accomplishing a mission is a non-linear
function of the cumulative production downtime and that this time cannot be
obtained using conventionalMarkov based techniques. The paper also introduces
an analytical model and a procedure that allows the density function of the
downtime to be obtained and shows how, using these tools, the production costs
and the quality of service may be assessed and related to the internal design of
the shop floor. The method seems to be particularly valuable in the analysis
of production systems integrated in just-in-time supply chains, in which the
reliability of the deliveries is an outstanding requirement.
