all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or

INTRODUCTION
This part of IEC 62264 shows activity models and data flows for manufacturing information
that enables enterprise-control system integration. The modelled activities operate between
Level 4 logistics and planning functions and Level 2 manual and automated process control
functions. The models are consistent with the object models given in IEC 62264-1 and the
Level 3 (manufacturing operations and control) definitions.
The goal of the standard is to reduce the risk, cost and errors associated with implementing
enterprise systems and manufacturing operations systems in such a way that they inter-
operate and easily integrate. The standard may also be used to reduce the effort associated
with implementing new product offerings.
This standard provides models and terminology for defining the activities of manufacturing
operations management. The models and terminology defined in this standard are:
– to emphasize the good practices of manufacturing operations;
– to be used to improve existing manufacturing operations systems;
– to be applied regardless of the degree of automation.
Some potential benefits produced when applying the standard may include
– reducing the time to reach full production levels for new products;
– enabling vendors to supply appropriate tools for manufacturing operations;
– enabling more uniform and consistent identification of manufacturing needs;
– reducing the cost of automating manufacturing processes;
– optimizing supply chains;
– improving efficiency in life-cycle engineering efforts.
It is not the intent of this part of the standard to
– suggest that there is only one way of implementing manufacturing operations;
– force users to abandon their current way of handling manufacturing operations;
– restrict development in the area of manufacturing operations;
– restrict use only to manufacturing industries.

4 Structuring concepts
4.1 Manufacturing operations management
The activities of manufacturing operations management are those activities of a
manufacturing facility that coordinate the personnel, equipment, material and energy in the
conversion of raw materials and/or parts into products. Manufacturing operations
management includes activities that may be performed by physical equipment, human effort
and information systems.
Manufacturing operations management shall encompass the activities of managing
information about the schedules, use, capability, definition, history and status of all of the
resources (personnel, equipment and material) within, and associated with, the manufacturing
facility.
NOTE 1 Resources associated with the manufacturing facility but not within it may include, among others,
government inspectors, regulatory certifications, resource coordination with other entities, outsourced activities and
processes.
The manufacturing operations management activities correspond to the activity set defined in
IEC 62264-1. These are the activities contained within the heavy dotted line shown in
Figure 1. The heavy dotted line is equivalent to the Level 3/Level 4 interface defined in IEC
62264-1. Manufacturing operations management shall be subdivided into four categories:

62264-3 © IEC:2007 – 13 –
production operations management, maintenance operations management, quality operations
management and inventory operations management, as shown in shaded areas in Figure 1.
NOTE 2 There are also other activities of a manufacturing facility, not shown in Figure 1, but described in
Annex A.
NOTE 3 The model structure does not reflect a business organizational structure within a company but is a model
of activities. Different companies assign responsibilities for activities or sub-activities to different business
organizational groups.

4.2 Functional hierarchy
IEC 62264-1 defines a functional hierarchy model. This standard specifies that each level
shall provide the functions listed below and illustrated in Figure 2.
Level 0 defines the actual physical processes.
Level 1 defines the activities involved in sensing and manipulating the physical processes.
Level 1 typically operates on time frames of seconds and faster.
Level 2 defines the activities of monitoring and controlling the physical processes. Level 2
typically operates on time frames of hours, minutes, seconds and sub-seconds.
Level 3 defines the activities of the work flow to produce the desired end-products. It
includes the activities of maintaining records and coordinating the processes.
Level 3 typically operates on time frames of days, shifts, hours, minutes and
seconds.
Level 4 defines the business-related activities needed to manage a manufacturing
organization. Manufacturing-related activities include establishing the basic plant
schedule (such as material use, delivery and shipping), determining inventory levels
and making sure that materials are delivered on time to the right place for
production. Level 3 information is critical to Level 4 activities. Level 4 typically
operates on time frames of months, weeks and days.

4.3 Manufacturing operations management elements
The shaded areas in Figure 1 represent the manufacturing operations management activities
modelled in this standard. Manufacturing operations management is the collection of
production operations management, maintenance operations management, quality operations
management, inventory operations management and other activities of a manufacturing
facility.
This standard defines four formal models: production operations management, maintenance
operations management, quality operations management and inventory operations
management. These are detailed in Clauses 6, 7, 8 and 9 and are listed below.
a) The production operations management model, which shall include the activities of
production control (3.0) that operate as Level 3 functions and the subset of the production
scheduling (2.0) that operate as Level 3 functions and as shown in Figure 1.
b) The maintenance operations management model, which shall include the activities of
maintenance management (10.0) that operate as Level 3 functions.
c) The quality operations management model, which shall include the activities of quality
assurance (6.0) that operate as Level 3 functions.
d) The inventory operations management model, which shall include the activities of
management of inventory and material including product inventory control (7.0) and
material and energy control activities (4.0) defined as operating as Level 3 functions and
as shown in Figure 1.
NOTE Other categories of operation management may exist depending on company policy or organization. They
are not formally modelled in this standard but they can make use of the generic standard model.
4.4 Criterion for defining activities below Level 4
The criterion for defining the activities to be included as a Level 3, 2, or 1 activity shall be that
the activity is directly involved in manufacturing and includes information about personnel,
equipment, or material and meets any of the following conditions.
a) The activity is critical to plant safety.
b) The activity is critical to plant reliability.
c) The activity is critical to plant efficiency.
d) The activity is critical to product quality.
e) The activity is critical to maintaining regulatory compliance.
NOTE 1 This includes such factors as safety, environmental and cGMP (current good manufacturing practices)
compliance.
EXAMPLE: Maintaining regional, government and other agency compliance.
NOTE 2 This list is a clarification of the criteria for inclusion of an activity in Level 3, 2, or 1 domain defined in
IEC 62264-1. This list supersedes the criteria defined in IEC 62264-1.
NOTE 3 There are other criteria such as company policy and organizational structure, or the nature of the
operations that could expand the scope of manufacturing operations management. See Annex B.
NOTE 4 Such activities as personnel management of salaries and job titles may be important for running a
manufacturing business, but they are not considered part of manufacturing operations management.
NOTE 5 Absolute plant efficiencies may be dependent upon factors that are outside the control of a facility (MRP
schedules, product mixes, etc.). These activities are not part of Level 3, 2, or 1.
4.5 Categories of production information
IEC 62264-1 defines the models and terminology to be used for enterprise-control system
integration. It contains a definition of three general categories of information that should be
exchanged between the business planning system (Level 4) and the manufacturing operations
system (Level 3). The result of IEC 62264-1 includes object models for the three categories.
