The inventory management computer 6 of the inventory central management center 5 stores the inventory information transmitted from each ready-mixed concrete manufacturing factory in the customer database sequentially, and the inventory central management center 5 uses the cement of the customer as necessary. It is possible to confirm the scheduled out-of-stock date by displaying the status.

Further, the computer can analyze the stock amount and the use status to estimate the scheduled out-of-stock date and output the order schedule information to a display device or the like for confirmation. In this way, if the scheduled date of the cement out-of-stock at the ready-mixed concrete manufacturing plant 4 is known early, it is transmitted to the cement manufacturing plant 3 as manufacturing / delivery information. There is an advantage that it can be set up in detail and more efficient production and delivery become possible.

As described above, the cement order information and the stock information are automatically transmitted from the stock amount monitoring device 7 of the ready-mixed concrete manufacturing plant 4 to the stock central control center 5. Labor saving without requiring a person in charge of inventory management. Also,
The cement company 1 centrally manages the cement stock of the ready-mixed concrete manufacturing plant 4 at the centralized inventory control center 5, so that there is no need for an abrupt order and no need to hold extra stock, and production and delivery are planned. As a result, the efficiency can be improved, and the cost can be reduced. In addition, the cement company 1 can develop a new business of expanding sales of cement on condition that the cement company manages the cement inventory of the ready-mixed concrete production plant 4.

Further, in the ready-mixed concrete manufacturing plant 4, the amount of cement used is not always constant every day, and is greatly varied depending on the amount of work. At this time, if the amount of cement used is known in advance, these data are input in advance to the inventory monitoring computer 7 and transmitted to the inventory management computer 6 of the inventory central management center 5 together with the inventory information. If the information can be viewed by access from the inventory management computer 6 side, if the prediction is made in consideration of these data at the time of the prediction of the cement replenishment date, a more realistic prediction is performed. be able to.

In the above embodiment, the cement silo 8 was used.
Although the inventory amount is detected by the level meter 9, the inventory amount may be calculated from the cement usage amount.
