PERA Enterprise Integration Website

The purpose of this website is to provide practical assistance in the planning, implementing, operating, and upgrading of Enterprise Control and Information Systems.

It includes:

• The Purdue Reference Model for Computer Integrated Manufacturing, (or Purdue Model)
  which incorporates the three basic components of any enterprise:

• Production Facilities (pink).
• Humans and Organization (magenta), and
• Control and Information Systems (blue)

These are shortened to Facilities, People and Systems as shown in the "PERA Pie" Diagram (at upper right).

• The Purdue Model addresses all Lifecycle Phases of the enterprise, including:
• Enterprise Definition
• Conceptual Engineering
• Preliminary Engineering
• Detail Engineering
• Construction
• Operations
• Decommissioning
• Enterprise Dissolution

After Decommissioning, instead of Enterprise Dissolution, the Owner may choose to renovate or upgrade the facility. In this case the lifecycle will "circle back" to Construction, Engineering or even Enterprise Definition.

These Lifecycle Phases may sometimes be called by different names or combined in different ways (e.g., Master Planning, Implementation, Operations, and Refurbishment or Renovation). In this case, the PERA Lifecycle phases may be easily "mapped" to other names. However, the concepts remain the same.

The PERA Master Planning Methodology
which provides a structured way to plan:
• A New Enterprise,
• An Enterprise Program, or
• A Unique Enterprise Project (e.g., a new production process or country).

It is used at the beginning of the enterprise, program, or project, typically during the Study and/or Conceptual Engineering phases. It may also be repeated and/or renewed at various points during the enterprise life cycle, including during Operations Phase or when major revamps or additions are undertaken.

• A PERA Master Plan addresses fundamental decisions including:

  Objectives Opportunities To-Be Facilities, Systems, and People Transition Plan including Training Implementation Plan

  Policies Standards As-Is Facilities, Systems, and People Projects including cost/benefits Periodic review and renewal

• Together, the Purdue Model and Master Planning address Control and Information Systems including:


• Logical Enterprise Architecture including major systems and data flows between them.


• Physical Enterprise Architecture including devices and the networks that connect them


• The full lifecycle of an Enterprise from Enterprise Definition to Enterprise Decommissioning.


• Different Enterprises including continuous process industries, discrete manufacturing, or service providers.
   Each industry sector contains multiple:
•     |_Principal Roles in that Industry including Owner/Operator, Vendor, EPC, and Service Providers,
          which themselves contain multiple:
•          |_Professional Roles in that Organization such as Control Engineer or Plant Manager.
  

The Navigation bar at the left selects "Topics" including PERA Introduction, Standards, Project Management, Cybersecurity, etc.

These Topics have been updated and expanded as part of the PERA+ Upgrade, and some Topics, including Cybersecurity, Risk Management, AI and Robotics, are new additions.
