The personnel model in ISA-95 is an abstract model that allows the definition of person and roles that individual persons can be assigned to PersonnelClasses (see Figure 22). The requirements associated with a given role may include specific training or certification. It may be related to Job Titles or skills. A single person may be associated with multiple roles. Persons may be grouped into a type of Person, to allow properties to be associated with all persons that fall into the given type. For example a Person Type of Operator type may allow, multiple operators to have the same defined qualification tests, some of which are defined by the operator role, others may be defined by safety role or a role for a specific type of equipment.

Figure 22- Personnel Overview

Figure 23illustrates personnel model which consists of specific person, ISA95Classes of personnel, and qualification of personnel. It includes an example subtype that illustrates creating customized sub type of PersonnelClass. The illustration further illustrates creating actual instance of the individual types and how multiple classes can be combined into a single instance. This figure does not illustrate how a subtype of PersonType can be created and used to classify multiple persons as being of the same type. The concept of a sub type of PersonType is allowed, but since most persons would have unique training and classification in many cases subtypes of PersonType would not exist.

The PersonnelClassPropertyType is a concrete VariableTypethat can be used directly. It is a subtype of ISA95ClassPropertyType defined in 7.5.4.

This VariableTypeindicates ISA95ClassProperties for ISA95PersonnelClass. Variablesof this VariableTypemay be associated to the qualification test specification defined in 8.1.3.1.

<TestResult> is the results associated with qualification tests for this PersonPropertyType. These test results can have any name but shall be referenced using the HasTestResult Referenceand shall be of type QualificationTestResultType or a subtype of it. In addition each <TestResult> shall have a ResultsForSpecification Reference to the instance of a QualificationTestSpecificationType that is associated to the given test result record. It is recommended that the names assigned to the object of QualificationTestSpecificationType and the <TestResult> variable follow some naming convention, to allow operators to more easily match test results to the test specification that they are for.

<PropertyName> is a placeholder for possible additional nested instances of PersonPropertyType. These instances of PersonPropertyType can have any name but shall be referenced using the HasISA95Property reference and shall be of type PersonPropertyType or a subtype of it.

<TestSpecification> is a placeholder for any test specification that this PersonPropertyType conforms to. These test specifications can have any name but shall be referenced using the TestedByQualificationTest Referenceand shall be of type QualificationTestSpecificationType or a subtype of it.

The QualificationTestSpecificationType is a concrete ObjectTypethat can be used directly. It is a subtype of ISA95TestSpecificationTypedefined in7.6.4.

This ObjectTypeindicates a qualification test specification. A qualification test specification may be associated with an ISA95PersonnelClass, an ISA95PersonnelClassProperty, an ISA95Person, or ISA95Person Property. This is typically used where a qualification test or ISA95Properly demonstrated competency is required to ensure that an ISA95Person has the correct training and/or experience for specific operations. A qualification test specification may test for one or more ISA95Properties.
