Application module: Required resource | ISO/TS 10303-1267:2004(E) © ISO |
This clause specifies the information requirements for the Required resource application module. The information requirements are specified as the Application Reference Model (ARM) of this application module.
NOTE 1 A graphical representation of the information requirements is given in Annex C.
NOTE 2 The mapping specification is specified in 5.1. It shows how the information requirements are met by using common resources and constructs defined or imported in the MIM schema of this application module.
The following EXPRESS specification begins the Required_resource_arm schema and identifies the necessary external references.
EXPRESS specification:

NOTE 1 The schemas referenced above are specified in the following part of ISO 10303:
Classification_assignment_arm ISO/TS 10303-1114 Resource_item_arm ISO/TS 10303-1268 Value_with_unit_arm ISO/TS 10303-1054
NOTE 2 See Annex C, Figures C.1and C.2 for a graphical representation of this schema.
This subclause specifies the ARM types for this application module. The ARM types and definitions are specified below.
The required_resource_classification_item type is an extension of the classification_item type. It adds the data types Required_resource, Required_resource_assignment and Required_resource_relationship to the list of alternate data types.
NOTE The list of entity data types may be extended in application modules that use the constructs of this module.
EXPRESS specification:

EXTENSIBLE
GENERIC_ENTITY
SELECT
BASED_ON
classification_item
WITH
(Required_resource,
Required_resource_assignment,
Required_resource_relationship);
END_TYPE;
(*
The required_resource_item type is an extensible list of alternate data types. Additional alternate data types are specified in select data types that extend the required_resource_item type.
NOTE This empty extensible select requires extension in a further module to ensure that entities that refer to it have at least one valid instantiation.

END_TYPE;
(*
This subclause specifies the ARM entities for this module. Each ARM application entity is an atomic element that embodies a unique application concept and contains attributes specifying the data elements of the entity. The ARM entities and definitions are specified below.
A Required_resource is an identified need for resource. The role of a required resource is determined by classification.
EXAMPLE 1 "facility", "test equipment", "supervisor" are examples of classifications of a required resource.
EXPRESS specification:

Required_resource_by_specification));
name : STRING;
description :
OPTIONAL
STRING;
required_quantity :
OPTIONAL
Value_with_unit;
END_ENTITY;
(*
Attribute definitions:
name: the words by which the required resource is known.
description: the text that provides further information about the required resource. The value of this attribute need not be specified.
required_quantity: the required quantity of the required resource. The value of this attribute need not be specified.
EXAMPLE 2 Quantity can be specified using amount or duration.
EXAMPLE 1 task, task step, activity, activity method, organization are examples of entities to which the resource requirement statement could be related.
The role of the assignment is determined by classification.EXAMPLE 2 The assignment can be classified as "required by".
NOTE An association between a required resource and actions that are needed prior to its usage.
EXAMPLE 3 A resource required by the activity "12" needs to be calibrated prior to usage. The calibration activity "21" is associated with the same required resource.using
EXAMPLE 4 A resource required by the task "123" needs to be disposed after its usage. This disposal task "456" is associated with the same required resource.
EXPRESS specification:

ENTITY Required_resource_assignment;
assigned_resource : Required_resource;
item : required_resource_item;
END_ENTITY;
(*
Attribute definitions:
assigned_resource: the required resource that is to be associated with the requiring entity.
item: the entity to which the required resource statement is assigned.
EXPRESS specification:
*)
ENTITY Required_resource_by_resource_item
SUBTYPE OF (Required_resource);
resource_item : Resource_item;
END_ENTITY;
(*
Attribute definitions:
resource_item: a reference to an item that is defined as a resource within the application context. It can refer to an actual as well as to a type of resource.
EXAMPLE Tool kit, facility, and product category are examples of resource items.
EXPRESS specification:

ENTITY Required_resource_by_specification
SUBTYPE OF (Required_resource);
END_ENTITY;
(*
EXAMPLE 1 "alternative" and "realized by" are examples of required resource relationship.
EXAMPLE 2 A Required_resource_by_specification for a power supply can be realized by a Required_resource_by_resource_item with part number "ABC-1234".
EXPRESS specification:

(*
Attribute definitions:
name: the words by which the relationship is known.
description: the text that provides further information about the relationship. The value of this attribute need not be specified.
relating: one of the instances of Required_resource that is a part of the relationship.
related: the other instance of Required_resource that is a part of the relationship. If one element of the relationship is dependent upon the other, this attribute shall be the dependent one.
