TIMED PETRI NETS PERSPECTIVE ON WEAVING PROCESSES

This study deals with warping and weaving focusing on the conceptual planning stage during which valid approximation based methods are needed. It introduces a decomposition method, directly derived from Timed Petri Nets (TPN) theories, to calculate the expected utilization of the processing equipment (the looms). The decomposed TPN model enables a quick calculation of the resources expected utilization at steady state thus providing a stick yard against which to verify its long run simulation based estimate.
