AI Technical Summary

Technical Problem

The prior art has failed to effectively establish a queue network model with blocking effects and generally distributed service time in the flexible intelligent manufacturing unit system, resulting in facilities being prone to deadlocks, thereby increasing the production cost of workpieces.

Method used

Design a flexible intelligent manufacturing unit system, including feeding outlet buffer zone, feeding outlet buffer zone and robot. Each workstation has a limited capacity buffer zone and processing equipment. The task processing time is subject to general distribution, and the service rules are first come first service. The robot transport speed is constant, and the blocking mechanism is blocking after service and blocking before service to avoid deadlock. At the same time, the target optimization problem is used to construct the system facility layout optimization problem based on the process path, and the queuing network model and neural network model are approximately solved to optimize the facility layout to improve the average output rate.

Benefits of technology

It effectively reduces the production cost of workpieces, solves the problem of deadlock in facilities, improves the output efficiency of workpieces of the system, realizes the optimization of the facility layout, and ensures the efficient operation of the system.
