This is called deadlock. This paper presents the sufficient conditions for deadlock to exist in a FMS; it models a FMS using digraphs to calculate slack, knot, order and space; it identifies three types of circuits that are fundamental in determining if a FMS is in deadlock....
If deadlock occurs, the automaton does not arrive at the goal at all. To overcome this drawback, we address a sufficient condition for designing a family of deadlock-free sensor-based path-planning algorithms in an uncertain world. Within this family, the automaton basically goes straight to ...

Deadlock in manufacturing systems: application of its necessary and sufficient conditionsThis paper is organized as follows: Section 2 presents a short description of the construction of the simple static model of a manufacturing system; Section 3 defines the dynamics of part movements within the ...
