Purdue Enterprise Reference Architecture (PERA), or the Purdue model, is a 1990s reference model for enterprise architecture, developed by Theodore J. Williams and members of the Industry-Purdue University Consortium for Computer Integrated Manufacturing. [1]

Overview

PERA is a reference architecture that can model the enterprise in multiple layers and in multiple stages of the architectural life cycle. Initially PERA was part of the PERA methodology, which consisted of three main building blocks: [2]

PERA has been further developed, and according to Gary Rathwell, PERA nowadays consists of the following components: [3]

  • The PERA Enterprise Life-cycle Framework or Model or Architecture...
  • Concepts of maximum and minimum lines of automation...
  • Concepts explaining the effect of recycle and time delays on the design and operation of facilities.
  • The PERA Master Planning Methodology
  • Concepts for dividing Enterprise Systems into Physical and Logical Architectures.
  • Purdue Reference Model for CIM including Generic Reference Data Flow Models.
  • Example Logical System Architectures from various industries...
  • Physical Systems Architecture Concepts including "Levels" and the "4Rs".
  • Example Physical architectures from various industries ...
  • Mapping of hardware and software products within the PERA Framework

Later in the 1990s combined insights from PERA, and other reference architectures such as GRAI Integrated Methodology, CIM-OSA, and TOVE has led to the development of the Generic Enterprise Reference Architecture and Methodology [4]

Levels for enterprise integration

Purdue Reference Model, “95” provides a model for enterprise control, which end users, integrators and vendors can share in integrating applications at key [5] layers in the enterprise:

CIMOSA, standing for "Computer Integrated Manufacturing Open System Architecture", is an enterprise modeling framework, which aims to support the enterprise integration of machines, computers and people. The framework is based on the system life cycle concept, and offers a modelling language, methodology and supporting technology to support these goals.

Computer-integrated manufacturing (CIM) is the manufacturing approach of using computers to control the entire production process. This integration allows individual processes to exchange information with each part. Manufacturing can be faster and less error-prone by the integration of computers. Typically CIM relies on closed-loop control processes based on real-time input from sensors. It is also known as flexible design and manufacturing.

Enterprise modelling is the abstract representation, description and definition of the structure, processes, information and resources of an identifiable business, government body, or other large organization.

Manufacturing execution systems (MES) are computerized systems used in manufacturing to track and document the transformation of raw materials to finished goods. MES provides information that helps manufacturing decision-makers understand how current conditions on the plant floor can be optimized to improve production output. MES works as real-time monitoring system to enable the control of multiple elements of the production process.

Enterprise control is the ability to combine control, intelligence and process management to enable business optimization that is inclusive of business and production operations. It combines the strength of both business processes and production operations processes. It is the deliberate act of synchronizing business strategy with operational execution in real-time to enable closed loop business control across an enterprise.

The history of business architecture has its origins in the 1980s. In the next decades business architecture has developed into a discipline of "cross-organizational design of the business as a whole" closely related to enterprise architecture. The concept of business architecture has been proposed as a blueprint of the enterprise, as a business strategy, and also as the representation of a business design.
