Lecture 21/22 - AM - Part 3 Flashcards
Two types of LOS?
Consumer LOS and Technical LOS
Describe Consumer LOS
Relatable for the consumer, more broad, ie safe, smooth, comfortable.
Describe technical LOS
Much more technical, engineering terms.
What is reactive?
unplanned, for immediate needs.
What is strategic?
performed early in lifecycle
What is emergent?
reduce the need to perform reactive repair. can see reactive repair needing to be done sometime soon.
For the equivalent uniform annual cost (EUAC), what are the variable NPV, I, n, and k?
NPV = net present value i = discount rate, presumed 4% n = service life of rehab and maintenance k = year that maintenance will be performed.
What does LTPP stand for?
Long term pavement performance.
What is the SCRIM truck?
Sideway-Force Coefficient Routine Investigation Machine. Monitors skid resistance on a network scale.
Pressures that would effect an infrastructure asset management plan?
- Safety
- Planning
- Information management
- Legislation
- Public
- Staff
- Permits
- Engineering
- Traffic
- Budget/ programming
The Zachman framework
- For enterprise architecture in a organisation
- Logical structure
- Classifying and organising models or descriptive representations of an enterprise.
- Derived from analogous structures in architecture
- Also helps in managing enterprise change.
System architecture patterns - independent systems?
Do not share any process or data.
System architecture patterns - interfaced systems?
Simply connected systems or subsystems that can exchange information across the common boundary which they share.
Systems share data but no processes.
System architecture patterns - interoperable systems?
Provide and accept services from the other systems and use the services exchanged to enable them to operate effectively together.
systems share limited processes and data.
System architecture patterns - integrated systems?
Tightly coupled interconnection of different, highly specialised devices, systems or subsystems, into a broader system providing complex functions which require close interactions between its components.
Systems share many processes and data.
Conceptual data model? (phase 1)
High level (conceptual data model) definition of the main model entities and relationships between them.
Logical Data Model? (phase 2)
More detailed design. Intermediary between conceptual and physical design.
Includes draft of the data dictionary and CRUD (create, read, update and delete) matrices.
Physical data model
Specifics that facilitate coding within a specific database management system (DBMS). (ie internal storage structures, access paths, file organisations).
Key components to complex systems?
Autonomous agents
Undefined values
Non linearity
What are autonomous agents?
Components that have their own freedom to govern themselves and/or control their own affairs.
ie stakeholders in the projects.
What are undefined values?
- known values - uncertainties
- know - underfined values
- unknown - underfined values (black swan event)
What is non linearity?
- most relationships are dynamic, non linear and hard to define.
Key components to define a complex system?
- System boundaries (scope)
- Influencing factors (in and out pressures)
- Nodes (stages in lifecycle)
- Links (between nodes)
- Feedback loops
What is the data needed for an AM plan?
- Investment costs over life of project
- Operational costs
- Benefits
- Discount rate
- Risk cost
What are the system data and functional requirements?
- Business drivers
- Information needs
- User requirements
- Consistency w/ business processes and procedures
- Functional requirements
- Data and system inputs
- System integration requirements
