Abstract

To recommend proper usage of a facility for quality maintenance to suppress the generation of manufacturing quality errors.SOLUTION: A facility diagnostic apparatus according to the present invention has a processor and a storage device. The storage device stores usage information defining a plurality of usages of each part of a facility manufacturing a product, weight information indicating a degree of influence given to manufacturing quality of the product by a deterioration state of each part when each usage is applied, target quality information indicating a target value of the manufacturing quality. The processor estimates the deterioration state of each part based on the state of each part, specifies the degree of influence corresponding to usage applied to the facility, estimates the manufacturing quality of the product based on the estimated deterioration state of each part and the specified degree of influence corresponding to the usage applied to the facility, and, based on a result of comparison between the estimated manufacturing quality and the target value of the manufacturing quality, selects the usage applied to the facility so that the manufacturing quality satisfies the target value.SELECTED DRAWING: Figure 1
