Abstract: A method and system for mutual exclusive control of resources. controlled by a computer, a programmable logic controller, or the like, sequentiaily available in an event driven process, in which a graph is generated in a storage device, the graph comprising nodes to which tasks included in a flow of process and critical resources are mapped, and each time a signal for beginning execution of a task is transmitted, a token is generated in the task node, and when the end of execution of the preceding task in the process flow is detected, the graph is referred to, and subsequently a signal is given for beginning execution of the immediately succeeding task nodes and the critical resource arranged in parallel with it.
