2. Description of the Related Art Generally, in physical distribution control, a transport destination and a transport route are set in advance according to the attributes of the transport product, and in actual operation, the transport product is transported so that the determined transport destination and transport route are protected. To be done.

However, during actual operation, a failure may occur in the transportation equipment, and the preset transportation destination or equipment on the transportation route may be physically unusable. In such a case, the operator needs to reset the transport destination and the transport route again. In the worst case, it is not possible to reset the transport destination and transport route during operation,
It may happen that the operation has to be stopped once. For this reason, there has been a problem that it cannot operate safely and efficiently.

As a prior art for solving this problem, for example, there is a transport control system disclosed in Japanese Patent Laid-Open No. 7-101552. This transfer control system, when work interference occurs in the transfer facility, controls the transfer according to the work priority between the interfered works.

However, in the physical distribution control in the transport system in which there are a plurality of transport destination candidates according to the attribute of the transported object, and there are a plurality of transport route candidates to each of the transport destination candidates, It is necessary to select the transport destination that seems to be optimal in advance from the transport destination candidates, select the transport route that seems to be optimal, from the transport route candidates, set the transport destination and the transport route, and perform the operation. is there.

Under such a condition, the initially set destination and its transport route may not be optimal due to the change of the destination by changing the attribute of the transported object or the change of availability of the transport device. In this case, it is not enough to simply carry out the transport control according to the priority of the work, and it becomes necessary to review the transport destination itself and the transport route itself. Therefore, the operator needs to adjust the optimal transport destination and the transport route each time to perform resetting, which causes a problem that the work load on the operator increases.

[0007] In actual operation, it is not known when the transportation equipment on the production facility becomes physically unusable due to a failure or the like. In addition, even if physically usable, the operator may temporarily disable it for maintenance or inspection. In addition, even if there are multiple destination candidates when transporting an item with a certain attribute, considering the subsequent work, it is a very suitable destination, or if it is not so suitable but it can not be helped There is also a transport destination that may be selected. Even when there are multiple transport routes from a certain transport source to the transport destination, it may be selected if it is a very suitable transport route in view of the subsequent work, or if it is not so suitable but it cannot be helped. There is also a transport route such as. In consideration of these, the operating conditions that change from moment to moment in actual work automatically select the most suitable transport destination and transport route for the operator at that time.
Instructing is effective for safe and efficient transportation.

The above-described transport control system of Japanese Patent Laid-Open No. 7-101552 performs transport control according to the work interference status and the work priority between the works that interfere with each other. If there are multiple transport route candidates and the transport route, and if the attributes of the transported item or the availability status of the transport device are changed during transport, then the transport destination and transport that most suit the operator's intention at that time. There was a problem that it did not have a function to re-instruct the route.
