An operation plan creation device that is configured to create an operation plan for a plurality of parts to be mounted in a device includes a setting data acquisition unit configured to acquire setting data including information on a time of start of an operation of the part and a time of a scheduled performance of inspection of the part, and information on parts that are candidates for assignment to the device, for each device, an operation plan creation unit configured to create data of the operation plan including an operation period of the part from the time of the start of the operation to the time of the scheduled performance of inspection using the setting data, and an assignability determination unit configured to determine an assignability for the part.

Operation plan creation device, operation plan creation system, operation plan creation method, and program

An apparatus for updating an operation plan of a high-temperature component based on operation performance. The apparatus includes: a display unit which displays an operation plan of multiple high-temperature components which are mounted upon a device; a storage unit which stores, for each device, at least initial setting data including information regarding operation start times of the high-temperature components and scheduled times for carrying out periodic inspections of the high-temperature components; an operation plan creation unit which, using the initial setting data, generates data of the operation plan including operation intervals of the high-temperature components from the operation start times to the scheduled times for carrying out the periodic inspections, and stores same in the storage unit for each device; and an operation plan update unit which updates the operation plan data which is displayed on the display unit, based on the high-temperature component operation performance information.

Operation plan creation device, operation plan creation method, and operation plan creation program

An operation plan preparation and evaluation device including a storage unit for storing master data related to equipment and a component, transaction data related to the equipment and the component generated when an operation plan is prepared, and an initial parameter used when the operation plan is prepared, and a control unit for preparing the operation plan based on the master data, the transaction data, and the initial parameter, in which the control unit performs a factor setting process of assigning a predetermined set value as the initial parameter, an operation plan preparation process of preparing the operation plan based on the initial parameter serving as the set value, the master data, and the transaction data, and an operation plan evaluation process of evaluating a plurality of respective operation plans prepared by repeatedly performing the operation plan preparation process while varying the initial parameter, and deriving an optimum operation plan.

Equipment maintenance component replacement prioritization planning system and method

A flaw detection image analyzer () takes in an inspection procedure command stored in a flaw detection condition database (), takes in a flaw detection image signal corresponding to a flaw detection image indicated by the taken inspection procedure command from a database () for flaw detection image signal, and displays the flaw detection image based on the flaw detection image signal on a display (), with a display range and a contrast indicated by the inspection procedure command in an arrangement pattern of image indicated by the inspection procedure command. Consequently, optimum images can be displayed sequentially with optimum arrangement pattern, optimum display range and contrast according to a flaw to be inspected when a flaw is detected by observing an ultrasonic flaw detection image.

When a three-dimensional structure is formed by welding a plurality of members, accurate welding can be performed matching the three-dimensional shape. The teaching data consisting of the three-dimensional position at each of the welding points determined on each of the welding lines at a predetermined spacing on the basis of the design data of the three-dimensional structure is stored in a memory. A laser slit light sensor (a laser slit light emitting sectionand a CD camera) is controlled by a total controllervia a camera controllerto photograph the welding point in order to obtain the image data of the welding point. An image processing apparatusprocesses the image data to determine the amount of deviation from the design data of welding points. The total controller modify the teaching data on the basis of the amount of deviation from the design data of welding points to establish the modified teaching data and controls a welding head so that it moves according to the modified teaching data.

Method of welding three-dimensional structure and apparatus for use in such method

A method and apparatus automatically repairs cracks produced in a member to be repaired. A wide field image is obtained by photographing the whole surface of a bladeor the like in a wide field view by a remote cameraand the position of cracks on the surface of the blade is obtained as a rough position information of the cracks by processing the image of wide field view. Then the cracks are photographed in a narrow field view at the predetermined spacing along the cracks based on the rough position information by a light section method. The narrow field images are processed to obtain the position, width, and depth of the crack at each predetermined spacing, which compose crack data at the series of points, and the cracks are repaired based on the crack data at the series of points.
