There is provided a maintenance recommendation system that creates an estimation model of failure modes of a new model of a device only from an occurrence probability of a failure mode. Based on an estimation model for an old model, the occurrence probability of a failure mode where a component is changed from the old model is updated only on a spot of a component change, and this creates an estimation model of failure modes intended for a new model newly commercially available. Thus, the attachment of the inspection result and the failure mode of a faulty facility is learned, an estimation model of failure modes is created to support facility maintenance services for a new model newly commercially available having a small amount of data of inspection results in failure daily reports for difficulty in learning.

In a production support system, process knowledge information is updated using machine learning on the basis of implementable process information, and implementable process information is output as a production plan of a product. Accordingly, production can be carried out considering factors, such as restart cost of facilities used in each of processes, for which skilled experience and knowledge are required with respect to the production of the product, and therefore the product can be produced effectively with low cost. Further, even when limitation conditions such as production capacity or quantity of a product exist for each of processes, suitable production can be carried out that satisfies these limitation conditions.

Production support system using multiple plan candidates and different types of learning devices

An input device (12) receives a natural language or conversational statement in the form of a character string (1). A processor (14) performs a natural language analysis (2) to convert the input natural language into a command language instruction for a computer program. A morphological analysis (3) compares words of the input character string with contents of a dictionary (10) to convert the input words into preselected words indicated by the dictionary which are output as another character string. In a semantic or syntax analysis (4; FIG. 9), one of the inputted and another character strings are analyzed to generate a corresponding chained functions structure (FIGS. 2, 3). From knowledge (FIG. 5, 7) described by the plurality of chained function structures and from rules stored in knowledge memory (11), a new character string is generated. If the new character string is in command language, the command is executed (7). If the new character string is not in command language, it is reanalyzed (8, 9) to generate yet another character string. In this manner, instructions can be input by a user in any of a multiplicity of national languages in conversational format and converted into appropriate command instructions for an executed computer program.
