Starting from the characteristics of production, we can see that the mechanical manufacturing industry has the main characteristics of discrete-based, process-assisted, assembly-focused. Taking equipment manufacturing as an example, the mode of production is generally composed of individual parts and final products, which is a typical discrete industry. Although the automobile manufacturing industry, such as die casting, surface treatment and other processes belong to the category of process, but most of the process is still characterized by discrete. Based on the above industry characteristics, the machinery industry has the following characteristics in the course of production and operation.

 

 

1, the production planning and production tasks management tasks are arduous.

 

 

Typical discrete machinery manufacturing enterprises are mainly engaged in single-piece and small-batch production, and the process of products is often changed. It is difficult to predict when the order will arrive because the production is mainly organized according to the order. Therefore, a good production planning system is needed for the purchase and production workshop planning.

 

 

 

2, the level of automation is relatively low.

 

 

Because of discrete processing, the quality and productivity of products depend largely on the technical level of workers. Automation is mainly at the unit level, such as CNC machine tools, flexible manufacturing systems and so on.

 

 

3, the process is simple and clear, the process is flexible, and the coordination of manufacturing resources is difficult.

 

 

The product structure of machinery industry is clear and definite. The product structure of a mechanical manufacturing enterprise can be described by the concept of number. The final product must be composed of fixed number of parts or components. These relations are very clear and fixed. Order oriented machinery manufacturing industry is characterized by multiple varieties and small batch. Therefore, the layout of production equipment in the machinery manufacturing industry is generally not according to the product but according to the process, the process of each product may be different, and there are more than one machine tool that can carry out the same processing technology. Therefore, it is necessary to schedule the processed materials, and intermediate goods need to be transported.
