AP233 Module Sets

The following identifies and describes the Module Sets for AP233, the STEP Systems Engineering Project.

Draft

• Text-based Requirements [ TBR ] - a data model that describes requirements as text strings with traceability, allocation, weighting and risk identified with each requirement.

• Property-based Requirements [ PBR] - a data model that describes requirements as structured and quantified formalisms that maybe decomposed from text-based requirements; can include tables, spreadsheets, graphs, charts, pictures and equations.

• Structural Models - a data model that describes how a system is built; defines the static relationships among
• 
  the subsystems, components, or parts that actually constitute the system; describes what is designed, built and maintained; contains specifications for design, manufacture, and maintenance and information about actual manufactured parts and their verification and maintenance

• Behavioral Models - a data model that describes how a system performs; includes functions, inputs, outputs and control operators which define the ordering of functions; the model describes Functional Flow Block Diagrams, Finite State Machines, Causal Chain, Data Flow Diagrams and Sequence Diagrams.

• Data Representation - "a consistent set of “presentation mechanisms” and “advanced schematics product model definition”, which is designed to present the computer sensible model data (defined in representation model space) onto a human understandable schematic diagram (presentation space), conforming to conventional and/or future draughting standards" [ from Intelligent Sematics PWI RDD ]

• Risk Analysis - a data model that identifies risk(s), describes their status, specifies relationships, likelihood, consequence, impact approach strategy and contingencies.

• Cost Models - a data model that describes direct, indirect, fixed, variable, material, administrative, finance, and contingency costs; provides linkage to system product structure(s)

• Scheduling - a data model that identifies activities, dependencies, durations and milestones associated with products described in the WBS; includes WorkFlow Diagrams, Network Schedules, Gantt Charts and Resource Leveling. [ work with PLCS ]

• Work Breakdown Structure - a data model that represents the structure used to represent the pieces of work necessary to complete a project.  [ work with PLCS ]
• 
   
• PDM - a data model that extends the STEP PDM Schema and PDM Modules to electro-mechanical, system engineering, product life-cycle and other non-physical domains.  [ work with PLCS and PDM ]
• 
   
• Security - a data model that describes project, organization, country and user defined security levels as well as user authentication and intellectual property.  [ work with PLCS and PDM ]
• 
   
• Organizational Structure - a data model that provides relationships, functional roles, skill qualification and documentation that defines an organizational structure.  [ work with PLCS ]
• 
   
• Validation and Verification Model - a data model that describes the plan, infrastructure and status of validation and verification processes.
• 
   
• Allocation Model - a data model that describes structures necessary to allocate requirements, schedule, costs, risks and other functions associated with a body of work.

• AP Interface Models - a data model that describes the interfaces between domain specific data models such as mechanical, electronic, structural analysis, thermal analysis, manufacturing, etc. [ work with other STEP AP groups ]
