制造行业主要分两大类：流程型与离散型。
流程型主要是采用物理或化学的方法对原材料进行混合、分离、粉碎、加热等工业生产，使原材料增值。除了启停及异常情况外，流程工业生产中的物料呈连续状态通过整个生产流程。典型的流程制造行业包括冶金、化工、石油及像我以前从事过的造纸行业。
离散型则主要是通过对原材料的物理形状进行改变或组合，使其成为产品并增值。离散型企业加工过程中物料呈离散状态，主要经物理加工和组装实现产品的工业生产。典型的离散制造行业包括械、汽车、电子、家电及像我以前从事的家具生产企业。

What are the differences in MES between process and discrete enterprises?
The manufacturing industry is divided into two main categories: process type and discrete type.
The process type mainly uses physical or chemical methods to mix, separate, crush, heat and other industrial production of raw materials to add value to raw materials. Except for start-stop and abnormal situations. The materials in process industrial production are in a continuous state through the entire production process. Typical process manufacturing industries include metallurgy, chemicals, petroleum and the paper industry, which I used to work in.
The discrete type is mainly through the physical shape of raw materials to change or combine. So that it becomes a product and adds value. In the process of discrete enterprise, the material is in a discrete state, and the industrial production of the product is mainly realized through physical processing and assembly. Typical discrete manufacturing industries include machinery, automobiles, electronics, home appliances, and furniture manufacturers like the one I used to work in.
