Abstract: A scheduling system and method for moving plural objects through a multipath system described as a freight railway scheduling system. The achievable movement plan can be used to assist in the control of, or to automatically control, the movement of trains through the system.

Abstract: A fault detection and redundancy management system for a dual redundancy based network architecture in which the principal control components (master units) are configured and programmed to repetitively carry out intra- and inter-unit performance tests as an a priori requirement for network command capability. These performance tests are carried out in a prescribed sequence to define the fault detection and reconfiguration procedure. The procedure is designed to preclude the cascading of faults. As a first step in this procedure, each processor in a master unit performs a thorough self-test of its own functional capability. Secondly, if a processor has determined that it has passed all of these internal procedures, it must then successfully inform a designated "chief" processor via an interprocessor handshake. This interprocessor handshake is effected by causing each processor in the master unit to set a flag in a shared memory during a prescribed time interval.
