Asset Management 3 Flashcards
What is New Zealand’s largest infrastructure asset
Pavement
Strategic Maintenance
performed early in pavement life
Emergent Maintenance
reduce need to perform reactive repair
Reactive
unplanned, for immediate needs
- restores the roadway to a serviceable condition
Lifecycle Programs
- Maintenance:
- Strategic
- Emergent - Reactive
Safety in AM
- keep the public safe
- cost generally increases with safety - balance
- Health and Safety can make a project unfeasible
Funding in AM
- bank loan
- company income
- government
- rates
- investment rates
- global financial market
Politics in AM
- political pressure
- public pressure
- election year
The Zachman Framework
- logical structure for classifying and organising models or “descriptive representations” of an enterprise
- derived from analogous structures in architecture
- building enterprise models help in accumulating large enterprise knowledge which is needed to accommodate change
Zachman Framework and IT
- Zachman framework is a thinking tool to understand many complex IT related issues
- helps in organising development thoughts
- also helps in developing strategies for creating flexible and agile enterprises
- by filling cells of Zachman matrix, information systems are automatically aligned with management corporate goals
System Architecture Patterns
- Independent Systems
- Interfaced Systems
- Interoperable Systems
- Integrated Systems
Independent Systems
do not share any processes or data
Interfaced Systems
- simply connected systems or subsystems that can exchange information accross the common boundary that they share
- systems share data, but no processes
Interoperable Systems
- provide and accept services from other systems and use the services exchanged to enable them to operate effectively together
- systems share limited processes, and data
Integrated systems
- tightly coupled interconnection of different, highly specialised devices into a broader system providing complex functions which require close interactions between its components
- systems share many processes and data
Phase 1
Conceptual Data Model
- may include a high level definition of the main model entities and relationships between them
- “high-level data model” synonymous with a conceptual data model
Phase 2
A Logical Data Model
- includes more detailed design and seen as intermediary between conceptual and physical design
- will include more specific information which will allow coding within a database, without necessarily including specific details that might ffacilitate coding with one particular DBM
Phase 3
Physical Data Model
- may include specifics which facilitate coding within a specific data base management system (DBMS) including for example internal storage structures, acceess paths and file organisation
Autonomous Agents in AM
- have their own freedom to govern themselves and/or control their own affairs
- e.g. stakeholders in the project
Key Components to Define a Complex system
- system boundary (scope of LOS and project)
- influencing factors (incoming and outgoing pressures)
- nodes (stages in LOS and project lifecycle)
- links (connections/communication between stages/nodes)
- feedback loops
Data needed for AM plan
- investment costs over life cycle of project
- operational costs
- benefits
- discount rate
- risk costs (consequence of failure)
Principles of Infrastructure Information Management Systems builds on key components
- hardware
- software
- data
- processes/procedures and standards
- people
