Embodiment 1

[0066] A specific embodiment of the present invention discloses an automatic production line optimization method based on buffer capacity calculation, such as figure 1 shown, including the following steps:

[0067] S1. Determine the production parameters of each process of the automated production line, the bottleneck process of the key section, and collect information on the operation of the initial production line to obtain the range of production parameters of each process; the key section refers to the operation mechanism and process characteristics that are complex and at the same time non-existent Linear, time-delayed, time-varying processes.

[0068] S2. According to the process flow and factory layout of the initial production line, establish the simulation model of the automated production line, load the initial values ​​of the production parameters of each process and run it, and obtain the production efficiency evaluation index.

[0069] S3. Change the values ​​of ...

Embodiment 2

[0074] Optimizing on the basis of Example 1, the method also includes the steps:

[0075] S5. Based on the optimized value of the cache area capacity and the factors affecting the production efficiency of the production line, run the simulation model of the automated production line again to obtain the availability B of the key section;

[0076] S6. Judging whether the linear ratio of the key segment availability B to the buffer capacity is less than the rated value, if less, determine that the buffer capacity at this time is the optimal value of the buffer capacity; if not less than, adjust the buffer capacity and the key Segment process beat until the linear ratio of key segment availability B to buffer capacity is less than the rated value. Then, update the initial production line according to the factors that do not affect the production efficiency, their optimized values, and the optimal value of the buffer capacity, and further serve as the optimal production line.
