What is mes structure?

As an AI language model, I don't have access to specific context regarding "mes structure". However, based on my general knowledge, here is some information about MES (Manufacturing Execution Systems) structure:

MES is a computerized system that is used in manufacturing plants to manage and monitor production activities in real-time. The structure of an MES system is typically composed of three main layers:

1. Database Layer: It is the bottom layer of the MES structure that stores all the data related to the production process. This data could include information about the products being manufactured, raw materials used, production schedule, etc.

2. Control Layer: It is the middle layer of the MES structure that is responsible for managing and controlling the manufacturing process. This could include functions like scheduling, routing, dispatching, etc.

3. Execution Layer: It is the top layer of the MES structure that is responsible for executing the manufacturing process. This could include functions like production monitoring, inventory tracking, quality control, etc.

In summary, an MES structure consists of a database layer to store production data, a control layer to manage and control production processes, and an execution layer to execute the manufacturing process.
