Optimization device for production line

An optimization device for a production line in which multiple production devices each execute a production process, the multiple production devices including multiple component mounters each configured to mount components on a circuit board by conveying the circuit board along the production line as the production process, at least a portion of the multiple production devices excluding the component mounters each executing a periodic operation accompanied by a stop of conveyance of the circuit board at a predetermined execution frequency during successive of the production processes,

• the optimization device comprising:
• a cycle time setting section configured to set a cycle time for each production device;
• a target time setting section configured to set a target time based on the cycle time and a required time for the periodic operation in each of the multiple production devices excluding the component mounters, and
• a line design section configured to calculate the unit number of the component mounters constituting the production line based on the target time.

An optimization device for a production line in which multiple production devices each execute a production process, the multiple production devices including multiple component mounters each configured to mount components on a circuit board by conveying the circuit board along the production line as the production process, wherein, when a mounting error occurs in which the component is not properly mounted on the circuit board in the production process by the component mounter, a required time of the production process is increased by a handling time in accordance with execution of an error handling corresponding to the mounting error, the optimization device comprising:

• a memory section configured to store error information in which an error rate and the handling time are set for each type of the mounting error, based on an assumption of the mounting error occurring at a predetermined error rate;
• a cycle time setting section configured to set a cycle time in each of the production devices, and configured to add the handling time of the mounting error to the cycle time of the component mounter;
• a target time setting section configured to set a maximum time of the cycle time in each of the multiple production devices except for the component mounters as a target time, and
• a line design section configured to calculate the unit number of the component mounters constituting the production line based on the target time.
