Abstract

A cell control apparatus controls a plurality of manufacturing cells each including a manufacturing machine. The cell control apparatus comprises an operation extraction part configured to extract a transferable operation which can be performed by a manufacturing cell having operation time to spare among operations of a manufacturing cell having delay in operation. The cell control apparatus commands the manufacturing cell having delay in operation to stop at least a part of operations in the transferable operation and commands the manufacturing cell having the operation time to spare to perform the at least the part of the operations.

Claims

1. A manufacturing management apparatus which is connected to a production planning apparatus for setting a manufacturing plan of a product and controls a plurality of manufacturing cells each including a manufacturing machine, the manufacturing plan including a number of products and a predetermined deadline, the manufacturing management apparatus comprising:

a plan reception part configured to receive the manufacturing plan of the product from the production planning apparatus;

an operation distribution part configured to set operating plan information including an operation content of a manufacturing cell on the basis of the manufacturing plan;

an operating information acquisition part configured to acquire operating result information which is information of the manufacturing cell when the manufacturing cell is operated;

a progress evaluation part configured to identify the manufacturing cell having delay in operation and the manufacturing cell having operation time to spare with respect to the number of products and the deadline set in the manufacturing plan by comparing the operating plan information and the operating result information; and

an operation command part configured to transmit an operation command to the manufacturing cell;

wherein

the plurality of manufacturing cells include a manufacturing machine having a wheel so as to be able to transfer from one manufacturing cell to another manufacturing cell,

the manufacturing management apparatus further comprises a machine extraction part configured to extract the manufacturing machine which can be transferred from the manufacturing cell having the operation time to spare to the manufacturing cell having the delay in operation, and

the operation command part transmits a command to transfer the extracted manufacturing machine from the manufacturing cell having the operation time to spare to the manufacturing cell having the delay in operation and further transmits a command to cause the transferred manufacturing machine to perform a part of the operations of the manufacturing cell having the delay in operation.

2. The manufacturing management apparatus according to claim 1, wherein the operation command part transmits an operation program from which the part of the operations is removed to the manufacturing machine having been arranged in the manufacturing cell having the delay in operation before a manufacturing machine is transferred and transmits an operation program for performing the part of the operations to the transferred manufacturing machine.
