Introduction
Manufacturing resources form the basis and long-term potential of any company. The efficient use of
these resources is one of the main goals in industrial management. Comprehensive information about
available manufacturing resources is required in order to take the necessary decisions for efficient
resource usage. Since many different enterprise functions and therefore also different IT-systems are
dealing with manufacturing resources. A common, standardized model for resource description is
necessary. That standardised model should enable a company to communicate internally and
externally about manufacturing resources and furthermore enable to build up an industrial company’s
resource database. Its basis will be the definition of an information model for the description of
manufacturing resources.
A complete description of manufacturing resources is out of scope of this information model. Only
data relevant for decisions concerning the usage of manufacturing resources (e.g. within process
planning or job scheduling) will be considered. Therefore only data describing manufacturing
resources in terms of their static and dynamic capabilities and capacities to perform manufacturing
tasks are within the scope of this information model for resource usage management. There mainly
exist two different types of capabilities. On the one hand, there exist capabilities describing a
manufacturing resource which are dedicated and unique characteristics in the context of resource
management. On the other hand, there exist capabilities which are used within resource management
but represent a specific view on characteristics belonging originally to the product description of a
manufacturing resource.
EXAMPLE  some geometrical or shape properties may belong to the product description and may be needed for
the management of concerned resource.

Therefore there is a strong link to the product defining data of manufacturing resources, e.g. described
by using the ISO 10303 standard.

On the other hand, the data residing in this information model for manufacturing resource management
will mainly be used within process planning. This planning will result in the assignment of
manufacturing resources and the required technological parameters for resource utilisation and these
results will be documented by means of ISO 10303-240 On the other hand the data describing
capability and capacity of manufacturing resources will be used together with process plans as input
for scheduling tasks which will be conceptually defined in ISO 15531-4x series.

This part of ISO 15531 specifies a model of manufacturing resources that is written in EXPRESS and
makes the fullest possible use of the “Integrated Resources” in ISO 10303. The model may therefore
be used by other SC4 standards.

3.1 Terms and definitions
For the purposes of this document, the following terms and definitions apply:
3.1.1
attribute
a piece of information stating a property of an enterprise entity
NOTE – The concept provided here relates to the broad concept of entity as defined in European standard
ENV 12204? The term entity used in the definition provided by the ENV 12204 has been replaced here by
enterprise entity as in ISO 15531-1 to avoid any confusion and inconsistency with the reserved term “entity”
defined in ISO 10303-11. The usage of this concept has been limited to the area of concern of ISO 15531 in
order to enable the use of the term “enterprise entity” instead of “entity and the field of application of the term
attribute is restricted to enterprise entities.

4 ISO 15531 general
ISO 15531 specifies the characteristics for a representation of manufacturing management information
over the entire industrial process with the necessary mechanisms and definitions to enable
manufacturing management data to be shared and exchanged within the factory, with other plants or
with companies.
Exchanges are made through different computer systems and environments associated with the
complete industrial process. The standard is focused on discrete manufacturing but not limited to it.
Nevertheless any extension to industrial processes which does not belong to discrete manufacturing is
always under consideration when it does not imply any contradiction or inconsistency with the initial
objective of the standard.
The following are within the scope of ISO 15531:

 the representation of production and resources information including capacity, monitoring,
maintenance constraints and control;

NOTE - Maintenance constraints and relevant maintenance management data are taken into account from the
point of view of their impact on the flow control.

 the exchange and sharing of production information and resources information including storing,
transferring, accessing and archiving.

The following are outside the scope of ISO 15531:

 enterprise modelling;
NOTE - That means that tools, architecture and methodologies for the modelling of an enterprise in its whole
are not in the scope of ISO 15531.

 product data (representation and exchange of product information);

ISO 15531-32 : 2005 (E)
 component data (parts library: representation and exchange of computer-interpretable parts library
information);
 cutting tools (electronic representation for exchange of cutting tool data);

 technical maintenance information (technical information such as those included in devices repair,
operation and maintenance manuals).

5 Conceptual information model for resources usage management data

5.1 Structure of the schema
According to ISO 15531-31 the conceptual information model for resources usage management data is
structured into six logical modules (see figure 1). The entity resource forms the central element within
the schema. Each further description classifying or detailing a resource’s characteristics is related to
this resource. The enumeration of these six modules follows a logical order. The ascending order
corresponds to the sequences for developing an information model.

ISO 15531-32 : 2005 (E)
5.1.1 Resource hierarchy
A resource hierarchy can be represented by instantiating a resource group. A generic resource captures
generic characteristics of a resource type. A specific resource is the specialisation of a generic resource
and captures a set of characteristics which represent a resource which can or does exist. The individual
resource represents the occurrences of manufacturing resources within the business.

NOTE  See box number 1 in figure 1.

5.1.2 Structure of resource characteristic

For the purposes of resource usage management, a resource characteristic comprises information about
a resource. The attribute classification enables the assignment of a resource characteristic classification
to a resource characteristic.
A resource administration represents a characteristic describing administrative information. A resource
capability identifies a characteristic specifying a functional aspect of a manufacturing resource. A
resource constitution represents a characteristic describing the constitution of a manufacturing
resources. A resource capacity identifies a characteristic dealing with job related data.

NOTE   See box number 2 in figure 1.

5.1.3 Resource status
A resource status is assigned to each individual resource. The resource status indicates the availability
or otherwise of the resource.
NOTE   See box number 3 in figure 1.

5.1.4 Definition of resource views

A resource view is derived from a specific aggregation of resources. A resource view is assigned to a
resource and can either be represented by a resource tabular layout of article characteristics or by a
resource user defined view.
NOTE  See box number 4 in figure 1.

5.1.5 Definition of resource characteristics

A resource representation is assigned to a resource qualitative or a resource quantitative to represent
physical values of the characteristic of a manufacturing resource.

NOTE  See box number 5 in figure 1.

5.1.6 Resource configuration
A resource configuration describes the configuration of a specific manufacturing resource.

5.3 Resources usage management type definitions

5.3.1 Resource classification type

The resource_classification_type type is one means by which the value of manufacturing resource
characteristics can be classified. It enables values to be represented which relate to what a resource has
been proposed to achieve, what a resource is required to achieve and what a resource has actually
achieved.

5.4 Resources usage management entity definitions

5.4.1 resource, library_resource_assignment
and library_property_assignment

5.4.1.1 resource
The resource is the basic element for resource management. Each further detailed description,
classification or configuration of resources relates to resource. A resource can be generic, specific or
individual and may in turn comprise of a number of other resources. Each resource has characteristics
and can also be considered from different viewpoints.

NOTE : A resource is not related a priori to a given activity. It exist and may be managed before any
appointment to any activity (See ISO 15531-1, ISO 15531-31). That is typically the case for Human resources.

EXAMPLE 1: A Factory can be considered as a resource, which contains other resources such as milling
machines and machine operators.

EXAMPLE 2: A 5 axis machining centre can be considered to have a generic set of characteristics. Alternatively
a particular manufacturers 5 axis machining centre will have a specific set of characteristics. An actual
occurrence of a resource used within the enterprise is an individual resource
