Purdue Enterprise Reference Architecture

PERA Reference model: Decision-making and control hierarchy, 1992

Purdue Enterprise Reference Architecture (PERA) is an 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 Equipment organization.

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 TOVIE 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]
