1.2 SCOPE

This recommended practice describes commonly used practices for the opportunity identification, justification, project management, implementation and maintenance of advanced control system applications in refinery services. This practice is not intended to specify the use or selection of any particular technique over another, nor is intended to describe specific applications. It may be used as the basis for defining the work processes and common actions required to define, implement and maintain advanced control system applications.

The practices described in this document are applicable to all advanced control system applications. Users who are experienced in advanced control may have developed their own equivalent practices. This document is not intended to supersede user practices that have been found to be acceptable or to require that the practices described in this document be followed if they are not appropriate to the circumstance.

Selection of a specific hardware platform, software platform or application software is not within the scope of this recommended practice.
