<p>A controller (2) is provided to a hydraulic shovel (1) operated on the market. The operation hours of the engine (32), front (15), pivot cab (13), and traveling gear (12) are measured. The data is stored in a memory of the controller (2), transferred to a base station computer (3) through satellite communication or an FD, and stored in a database (100) of the base station computer (3). The base station computer (3) reads data stored in the database (100) for each hydraulic shovel, and draws and outputs a diagram showing the distribution of the numbers of operating hydraulic shovels versus the working hours (engine working hours) of the hydraulic shovels. The number of hydraulic shovels to be replaced is predicted on the basis of the distribution diagram, the number of hydraulic shovels which may be sold is predicted, and the production plan of the hydraulic shovel is made. Thus, the number of construction machines which may be sold can be accurately predicted, and an appropriate production plan of construction machine can be made.</p> |
