4 Information requirements

This clause specifies the information requirements for the Condition evaluation 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 Condition_evaluation_arm schema and identifies the necessary external references.

EXPRESS specification:

*)
SCHEMA Condition_evaluation_arm;
(*

4.1 Required AM ARMs

The following EXPRESS interface statements specify the elements imported from the ARMs of other application modules.

EXPRESS specification:

*)
USE FROM Classification_assignment_arm;    --  ISO/TS 10303-1114

USE FROM Condition_arm;    --  ISO/TS 10303-1253
(*

NOTE 1   The schemas referenced above are specified in the following part of ISO 10303:

Classification_assignment_arm ISO/TS 10303-1114
Condition_arm ISO/TS 10303-1253

NOTE 2   See Annex C, Figures C.1and C.2 for a graphical representation of this schema.

4.2 ARM type definitions

This subclause specifies the ARM types for this application module. The ARM types and definitions are specified below.

4.2.1 condition_assignment_classification_item   EXPRESS-G

The condition_assignment_classification_item type is an extension of the classification_item type. It adds the data types Condition_evaluation, Condition_evaluation_assignment, Condition_evaluation_parameter and Related_condition_parameter 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:

*)
TYPE condition_assignment_classification_item = EXTENSIBLE GENERIC_ENTITY SELECT BASED_ON classification_item WITH
   (Condition_evaluation,
    Condition_evaluation_assignment,
    Condition_evaluation_parameter,
    Related_condition_parameter);
END_TYPE;
(*

4.2.2 condition_evaluation_item   EXPRESS-G

The condition_evaluation_item type is an extensible list of alternate data types. Additional alternate data types are specified in select data types that extend the condition_evaluation_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.

EXPRESS specification:

*)
TYPE condition_evaluation_item = EXTENSIBLE GENERIC_ENTITY SELECT;
END_TYPE;
(*

4.2.3 condition_evaluation_parameter_item   EXPRESS-G

The condition_evaluation_parameter_item type is an extensible list of alternate data types. Additional alternate data types are specified in select data types that extend the condition_evaluation_parameter_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.

EXPRESS specification:

*)
TYPE condition_evaluation_parameter_item = EXTENSIBLE GENERIC_ENTITY SELECT;
END_TYPE;
(*

4.3 ARM entity definitions

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.

4.3.1 Condition_evaluation   EXPRESS-GMapping table

A Condition_evaluation is a record of the evaluation of a Condition and the subsequent result.

EXAMPLE    A Condition is "If the measured value of oil pressure from gauge 3 on a car is less than 2 bar then check the oil level" When the condition is evaluated it is recorded by an instance of Condition_evaluation. The measured value of oil pressure from gauge 3 on car with VIN 12345678 is 1.9 bar. Therefore the result of the evaluated the condition is true.

EXPRESS specification:

*)
ENTITY Condition_evaluation;
  name : STRING;
  description : OPTIONAL STRING;
  result : LOGICAL;
  condition : Condition;
END_ENTITY;
(*

Attribute definitions:

name: the words by which the Condition_evaluation is known.

description: the text that provides further information about the Condition_evaluation. The value of the attribute need not be specified.

result: the indication whether the Condition evaluates to True, False or Unknown.

condition: the Condition that has been evaluated.

4.3.2 Condition_evaluation_assignment   EXPRESS-GMapping table

A Condition_evaluation_assignment is a relationship that identifies the statement or relationship to which the Condition_evaluation applies.

EXAMPLE    The Condition_evaluation (instance 87) is assigned to the activity of checking the oil level on car VIN 12345678.

EXPRESS specification:

*)
ENTITY Condition_evaluation_assignment;
  assigned_condition_evaluation : Condition_evaluation;
  item : condition_evaluation_item;
END_ENTITY;
(*

Attribute definitions:

assigned_condition_evaluation: the Condition_evaluation that is being assigned.

item: the product or activity data to which the Condition_evaluation has been assigned.

4.3.3 Condition_evaluation_parameter   EXPRESS-GMapping table

A Condition_evaluation_parameter is an identification of the product or activity data used in the evaluation of the Condition identified by the Condition_evaluation.

EXAMPLE    The measured value of oil pressure from gauge 3 on car with VIN 12345678 (value = 1.9 bar).

NOTE    The product or activity data is defined in condition_evaluation_parameter_item. The contents of this select type are defined in application modules that use this module.

EXPRESS specification:

*)
ENTITY Condition_evaluation_parameter;
  name : STRING;
  description : OPTIONAL STRING;
  condition_evaluation : Condition_evaluation;
  evaluation_parameter : condition_evaluation_parameter_item;
END_ENTITY;
(*

Attribute definitions:

name: the words by which a Condition_evaluation_parameter is known.

description: the text that provides further information about the Condition_evaluation_parameter. The value of the attribute need not be specified.

condition_evaluation: the Condition_evaluation for which the parameter was an input.

evaluation_parameter: the product or activity data which acted as a parameter to the Condition_evaluation.

4.3.4 Related_condition_parameter   EXPRESS-GMapping table

A Related_condition_parameter is a relationship between a Condition_parameter and a Condition_evaluation_parameter.

This relationship is used to record the relationship between the parameters used to define a condition and the parameters used to evaluate it.

EXAMPLE    The value of oil pressure (1.9 bar) used in Condition_evaluation (instance 87) was a measured value of the parameter used to define condition 29 (oil pressure on gauge 3).

EXPRESS specification:

*)
ENTITY Related_condition_parameter;
  name : STRING;
  description : OPTIONAL STRING;
  conditon_evaluation_parameter : Condition_evaluation_parameter;
  condition_parameter : Condition_parameter;
END_ENTITY;
(*

Attribute definitions:

name: the words by which the Related_condition_parameter is known.

description: the text that provides further information about the Related_condition_parameter. The value of the attribute need not be specified.

conditon_evaluation_parameter: the Condition_evaluation_parameter being related.

condition_parameter: the Condition_parameter being related.
