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) 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.



• 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 provides a structured way to plan:
• An Enterprise,
• An Enterprise Program, or
• An Enterprise Project.

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

• The PERA methodology is unique, in that it addresses:
• All Enterprises, including continuous process industries, discrete manufacturing, or service providers.
  Each of these contain:
• |___Principal Organizational Roles in that Industry including Owner/Operator, Vendor, EPC, and Service Providers,
  which themselves contain:
• |_____ Professional Roles in that Organization such as Control Engineer or Plant Manager.
  
  
• All Architecture Levels from plant equipment to the board room, and


• All Control and Information Systems from plant regulatory control to the Internet cloud applications.

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

All of these Topics have been updated and expanded as part of the PERA+ Upgrade, and some of them, including Cybersecurity, Risk Management, and New Technologies are new additions.

1. Promote concepts of enterprise integration including the latest work processes and tools,
2. Provide detail to explain when, how, and why to use PERA,
3. Use AI to more effectively deliver and maintain reference and educational materials.
4. Provide links to additional information, including tutorials, procedures and forms, reference systems, etc., to benefit end users.

While items 1), 2), and 3) are provided on this website for free, providers of additional information, publishers, software and service providers, may request payment.
