摘要： The present invention increases the productivity of an entire factory, even of the type that produces different types of products in different quantities using transport vehicles, by performing transport operation control. This transport operation control device is provided with: a spatial distribution measuring unit which measures the spatial distribution of products-in-process being transported by the transport vehicles; and an operation schedule calculation unit which, on the basis of the measured spatial distribution of the group of partly-finished products, calculates an operation schedule that specifies both a route and a frequency of a transport operation to be carried out by each transport vehicle of the transport vehicles, wherein the operation schedule calculation unit determines the timing with which to update the operation schedule, on the basis of changes in a productivity index that is determined from the measured spatial distribution of the products-in-process.

摘要： A mobile object control apparatus, with respect to a first mobile object and a second mobile object, predicts whether the first and second mobile objects will collide with each other at an intersection. The apparatus calculates, when the first and second mobile objects will collide with each other at the intersection, a speed of the first mobile object at which the collision can be avoided at the intersection. The processor extracts a third mobile object that is in an intersection area and has passed through the intersection, and estimates that the third mobile object has a high possibility of colliding with the first mobile object at the intersection. The intersection area is set at the intersection through which the first mobile object passes.

摘要： Provided is a conveyance-task control device that is able to appropriately control conveyance tasks between workstations. A conveyance-task control device (10) includes a task-priority calculation unit (11) and a conveyance-task determination unit (12). The task-priority calculation unit (11) calculates respective priorities of conveyance tasks on the basis of first parameters respectively indicating a degree of how much amount of products in process a plurality of conveyance subjects are conveying in corresponding ones of areas respectively including conveyance routes between a plurality of workstations. The conveyance-task determination unit (12) determines a conveyance task with a highest one of the respective priorities as a candidate for a conveyance task to be performed next.

摘要： An acquisition unit that acquires, based on a combination of failures in components of an information system, a correction subprocedure for identifying a cause of failure and correcting trouble and a reconstruction subprocedure for reconstructing the component; a generator that generates at least one candidate for a service restart procedure of the information system by connecting the correction and the reconstruction subprocedures based on a dependency relationship between the acquired correction and reconstruction subprocedures; an estimator that estimates required time of at least one candidate for the service restart procedure; and a selector that identifies the service restart procedure, of which required time satisfies desired restoration time from among the candidates for the service restart procedure and selects, from among the identified candidates for the service restart procedure that has the risk of exceeding the desired restoration time, the service restart procedure based on a high/low degree of the risk.
