Introduction
As a crucial part of the increasingly complex manufacturing systems, automation and control
applications which are enabled by advanced process control and optimization (APC-O) methodology
and solutions are implemented under the direction of production planning and scheduling. This task
involves initially the specific use of APC-O that will eventually enable the integration of manufacturing
operations management (MOM) with the automation and control of manufacturing process and
equipment.
Automation solutions equipped with both software and hardware components are provided by
different suppliers to accomplish APC-O functions. Due to the diversity of development environments
and the variety of demand focus, the automation solutions from various suppliers tend to be isolated
and relatively independent, which make it harder for the automation solutions to be integrated.
Consequently, various automation solution components that the customers can have access to are filled
with redundant and duplicated functions, resulting in a waste of resources and limited interoperability.
This document offers an interoperability framework for advanced process control and optimization
with the intention of maximizing both the integration and the interoperability of automation solutions.
It is not the intent of this document to suggest that there is only one way of implementing APC-O or to
force users to abandon their current way of implementing APC-O.
The target users of this document include users and providers of advanced process control and
optimization solutions, such as, project solution suppliers, automation systems integrators, production
departments of companies, process engineers, independent software testing organizations,
implementation and consulting service organizations of advanced process control and optimization
software, and relevant government and academic organizations.

5 Principle and purpose
5.1 Principle of verification and validation
This document provides a specification for both users and suppliers of the APC-O systems. The APC-O
system that conforms to the specification will satisfy the customer requirements and facilitate the
integration between different APC-O systems, as illustrated in Figure 1.
Figure 1 — Verification and validation of APC-O systems
Workflow: The workflow of an APC-O system relates to the phases of the lifecycle.
Output of lifecycle phase: Each work phase has an object.
Work phase: The lifecycle of an APC-O system consists of the following phases:
a) Requirements analysis;
b) Design;

5.2 Structures of indicators
5.2.1 General
Both the quantitative indicators and the judgement indicators are expressed in the manner of the
structure specified in ISO 22400-2. The structure identifies the descriptive element of indicator in the
left column and gives a description of each element in the right column.

ISO 15746-3:2020(E)
The aim of verification and validation is to check whether the work meets the needs of users.
a) Define the objective of V&V according to the users’ requirements.
b) Analyse the objective and make sure that the objective applies to the work in this phase.
c) Define the indicators and the checkpoints, the applicable formula and the evaluation method in
order to establish the checklist.
d) Review the indicators and the checkpoints to ensure that the checklist meets the requirements of
V&V. Update the indicators and the checkpoints if necessary.
e) Calculate the indicators, evaluate the checkpoints according to the checklist, and generate the
evaluation report.
f) Assess the evaluation report. There are three situations that indicate whether the evaluation
report fails or passes:
1) Errors have occurred during the process of indicator calculations and checkpoint evaluations,
and modification is needed.
2) The indicators and the checkpoints are not appropriate and need to be adjusted.
3) The work in this phase does not meet the requirements, and modification is needed.
5.4 Verification
The verification process for lifecycle phases complies with the general method of verification
process in 5.3.

Scope Requirement analysis phase
Evaluation method Check whether the scope of APC-O system application is consistent with
requirements of stakeholders.
EXAMPLE The object can be distribution column and absorption column.
Q1: What part of the physical plant will the APC-O system be applied to?
Answer to Q1: The APC-O system will be applied to distillation column
and absorption column in this project.
EXAMPLE The whole process includes totally five units according to the
stakeholders’ requirements, while only three out of the five units will
be applied with APC-O system. This checkpoint is to check whether the
determined three units have been correctly included.
