If an error is found, the specification will be decorated on the system printed label at the end of the test. According to the area where the defect is located, modifying the wire beam may be difficult. For example, to replace single -rooted wires, the thread beam and other fixed components of the entire affected area must be removed.

Use the tools created specifically for this purpose to modify, and repair the defect without affecting the quality of other components. After repairing the drawing, the wiring test process of restoring all functions.

After the test shows that the wiring can perform all the functions, the label that confirms this fact and puts it on the wiring. Packaging wiring is also an artificial process. The method of completing the deployment, the type of box for transportation, and the number of wires stored in the box are determined by the specifications with the customer (automobile manufacturer).

The chart in Figure 9 highlights the logistics process of dynamic loading, and outlines how manual and automatic processes are combined in wiring production.

4 Wire Bidding Process Optimization Case Study

The case study aims to determine the main factor of the dynamic assembly line productivity in the production of wire beam. To this end, the theoretical structure of the following assembly line is defined in the Witness Horizon software:

13 construction segments: 10 assembly sections, 2 testing sections, and 1 packaging section;

Nine buffers: 5 buffers are used to store meta devices, 1 buffer is used to store the cable before testing, and 1 buffer is used for each test section to store the line beam that is not passed. The buffer area is used to place the wiring beam before the packaging;

Install the conveyor belt under the assembly board to ensure that the beam branch is transported from one segment to another;

The assembly line is provided by 19 operators.

It simulates 8 hours a day, 5 days a week, that is, a single -shift system of 2400 minutes, as shown in the figure below:

After the simulation, it is noticed that the free time of each segment gradually increases after the work section 4, and the percentage of 97.56% in the last section reaches 97.56%.

This fact will affect productivity and cause the production process to be blocked, as shown in the figure below:

In order to optimize the assembly process, three assumptions have been considered:

The first assumption is to eliminate the free time of all sections
