Asset Management 3 Flashcards
(22 cards)
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
