Control unit having an inference function

A control apparatus having an inference function comprising:

• a plurality of sensor means for detecting the status of respective units of a machine;
• setting means for setting operating conditions of said machine;
• input means for inputting situations of problems and causes of the problems when the problems occur in said machine or in a product produced by said machine;
• inference means including storage means storing data to various solutions for said problems, said inference means including means for providing a priority order for said problems;
• and means for providing a priority order for causes according to the situations of the problems;
• means for providing a priority order for said solutions;
• the status of respective units of said machine being detected by said sensor means and the status information being stored in said storage means, means for inferring a solution which is most suitable;
• and
• means for changing the operating conditions of said machine set by said setting means in accordance with the solution inferred by said inference means.
