ISA 95

ISA-95 defines a hierarchical model for integrating enterprise and control systems in manufacturing, using levels like Enterprise, Site, and Area to structure information and activities. The Enterprise level represents the entire organization, while a Site is a specific physical location within the Enterprise. An Area is a defined section within a Site, focused on specific manufacturing activities. Here's a more detailed breakdown:

• Enterprise

  • Site

    • Area

      • Line

        • Cell

• Enterprise:The top level of the ISA-95 hierarchy, representing the entire company or organization. It encompasses all sites and their associated areas.

• Site:A physical location where manufacturing operations take place, like a factory or plant. A site can contain multiple areas.

• Area:A specific section within a site where a particular type of manufacturing activity occurs. Examples include areas for different processes, products, or functions.

This hierarchical structure allows for a clear and organized flow of information and activities from the top-level business functions down to the shop floor, facilitating better communication and coordination between different levels of the organization.
