Abstract: For reliable, failsafe monitoring of the locking of a closure device of a vehicle of a cableway is disclosed in which provision is made for an electrical connection to be established between a vehicle powerline modem on the vehicle and a station powerline modem, which is connected to the cableway controller, via a busbar in the station, with which contact is made by a current collector of the vehicle, and for the locking status of a locking unit to be transmitted from the vehicle to the cableway controller via this connection by means of powerline communication, wherein, in the event of defective locking, the vehicle is stopped in the region of a busbar in the station and the locking status is transmitted to the cableway controller again when the vehicle is at a standstill.

Abstract: A system and method for performing flexible workflow process execution in a distributed workflow management system is described. The distributed workflow management system is formed by a computer network comprising a plurality of computers. Each computer has a processor, memory and input/output facilities. A workflow process management system operates on one or more of the computers to control the computer network in executing the workflow process. The workflow process includes at least one sequence of multiple actions. A plurality of resources is coupled to respective ones of the computers to carry out the multiple actions. A plurality of state machines are stored as computer-operable code in at least one memory and include a plurality of states interconnected by arcs logically forming a directed graph. The workflow management system further includes logic for instantiating each action with one state and logic for executing the logical sequence of the action as state transitions in each state machine.
