Application module: Schedule | ISO/WD 10303-1437 |
ISO 10303 is an International Standard for the computer-interpretable representation of product information and for the exchange of product data. The objective is to provide a neutral mechanism capable of describing products throughout their life cycle. This mechanism is suitable not only for neutral file exchange, but also as a basis for implementing and sharing product databases, and as a basis for archiving.
This part of ISO 10303 specifies an application module for the representation of a data model that identifies activities, dependencies, durations and milestones associated with products described in a work breakdown structure. This includes the information necessary to produce Workflow Diagrams, Network Schedules, Gantt Charts and Resource Leveling.
Within organizations and between organizations it is beneficial to be able to exchange plans and schedules. These may be at a high level where they deal with the tasks of work breakdown structure or at low and detailed level where they coordinate individual workers. This module captures information concerning schedules, resource allocation and leveling. This information is needed to manage the life cycle process of developing and using a system such that persons and organizations can coordinate their activities.
This module is constructed from several ISO/TS Application modules.
The module Activity method implementation provides the capability to associate additional information with an activity method.
The module Attribute classificaton provides the association of a value, represented by a class, to an attribute of an entity.
The module Condition evaluation identifies the evaluation of conditions that impact an activity or its execution. The module records the parameter values evaluated and the logicalresult of the evaluation.
The module Process property assignment captures the specification of a property of an activity, the representation of a property of an activity, or the use of an independent property in the definition of an activity.
The module Property assignment provides for the:
The module Resource as realized captures the recording of resources used or consumed by activities. It captures the usage or consumption of actual resources and types of resource items. It captures the relationship between the resource actually applied and realized with the corresponding resource requirement statements. It captures the relationship between the resource as realized and the corresponding resource events.
The module Resource property assignment captures the definition of a property that may be associated with a resource or related element. It captures the representation of a property that may be associated with a resource or related element; the use of an independent property in the definition of a resource, and the means to assign a property to a resource or related element. The entity property includes time intervals.
The module Scheme captures the identification of schemes that support the ordering of activities. It captures the identification of entries in a scheme, and the association of dates and times with schemes and entries in schemes. It captures the definition of relationships between entries within a scheme, including dependencies and sequencing. It captures the definition of relationships between schemes, and the definition of relationships between scheme entries and schemes that expand on entries.
The module Task specification captures the specification of a task as a sequence of instructions encoded as text. It captures the specification of a task as a structured set of instructions. It captures the association of pre-conditions to a task or a stage within a task, the association of post-conditions to a task or a stage within a task, and the assignment of a task.
The module Time interval assignment captures the association of a time interval with product or activity data.
The module Work output captures the definition and quantification of planned and recorded output, the relationship between work outputs, and the relationships between the work output and detailed descriptions of the output.
Clause 1 defines the scope of the application module and summarizes the functionality and data covered. Clause 3 lists the words defined in this part of ISO 10303 and gives pointers to words defined elsewhere. The information requirements of the application are specified in Clause 4 using terminology appropriate to the application. A graphical representation of the information requirements, referred to as the application reference model, is given in Annex C. Resource constructs are interpreted to meet the information requirements. This interpretation produces the module interpreted model (MIM). This interpretation, given in 5.1, shows the correspondence between the information requirements and the MIM. The short listing of the MIM specifies the interface to the resources and is given in 5.2. A graphical representation of the short listing of the MIM is given in Annex D.
In this International Standard, the same English language words may be used to refer to an object in the real world or concept, and as the name of an EXPRESS data type that represents this object or concept.
The following typographical convention is used to distinguish between these. If a word or phrase occurs in the same typeface as narrative text, the referent is the object or concept. If the word or phrase occurs in a bold typeface or as a hyperlink, the referent is the EXPRESS data type.
The name of an EXPRESS data type may be used to refer to the data type itself, or to an instance of the data type. The distinction between these uses is normally clear from the context. If there is a likelihood of ambiguity, either the phrase "entity data type" or "instance(s) of" is included in the text.
Double quotation marks " " denote quoted text. Single quotation marks ' ' denote particular text string values.
