<p>PURPOSE:To shorten the down time by a failure, a repair and an inspection. CONSTITUTION:A preventive maintenance computer 10 connected to an upper class computer 1 to control a physical distribution system compares the basic data stored in a basic data storage device 11 with the operational condition data stored in an operational condition data storage device 12. For example, the basic data are the life time of the parts, the service life can be predicted irrespective of the variance of the operational load of each equipment by comparing the operation time transmitted from the upper class computer 1 with the integrated operational condition data, and outputted from a CRT 8 and a printer 9 of a work station 7.</p> |
