Summary, in English

Downtimes in a manufacturing cell, line or individual machines are characterized by a stochastic behavior that their frequency and their duration display. A method is presented here for analyzing this dynamic behavior from a cost perspective. An important element of the method is statistical analysis of downtimes, including empirical distribution functions pertaining to downtimes of specific types. For demonstrating this, use is made here of genuine downtime data obtained from the Swedish company Alfa Laval.
