document: A fractional-flow model of serial manufacturing systems with rework and its reachability and controllability properties A dynamic fractional-flow model of a serial manufacturing system incorporating rework is considered . Using some results on reachability and controllability of positive linear systems the ability of serial manufacturing systems with rework to `` move in space '' , that is their reachability and controllability properties , are studied . These properties are important not only for optimising the performance of the manufacturing system , possibly off-line , but also to improve its functioning by using feedback control online
