The dynamic analysis of the disruptions transmission in networks of closed loops formed by machines and intermediate buffers are of vital importance in most production systems. Nevertheless, little research has been done on optimization in this field up to the present. This study analyzes the disruption time transmission in a generic assembly system, which has been modelled as a network of closed loops of machines and intermediate buffers. In addition, this modelling has been used to analyze a real automobile assembly line, taking into account variables which have not been previously considered by the literature such as: working regimes of machines, their cycle times, capacities of the intermediate buffers and their minimum contents. The optimal configuration of the intermediate buffers is analyzed. Dynamic outlines of these kind of assembly systems are proposed in order to maximize the transmission of disruption times and hence, their availability. For this purpose, an algorithm for analyzing and optimizing availability in this kind of manufacturing systems has also been developed.
