Maintenance Planning Flashcards
The chain of operations having the longest total time
The critical path
The 4 steps of the critical path method
- Write out a list of activities in the project
- Determine the logical order of the activities
- Begin constructing the diagram in a preliminary form
- Analyze each activity
What do arrows and circles mean in CPM
Arrows: A complete activity from start to finish
Circle: An event
This is necessary to ensure facilities, equipment, and systems are installed and function properly
Commissioning
Pre-Commissioning activities
Site Acceptance Tests (SAT) - Verifies proper equipment and operation on site
Factory Acceptance Tests (FAT) - Testing the equipment or system at the factory
InVEST meaning
Integrate Verify Ensure Sensible Traceable
SMART meaning
Sensible Maintainable Accurate Range Traceable
A calculated approximation using past experience or suggesting expected prices
Cost estimate
A calculated approximation of how long a job will take to complete
Time estimate
The time charged for a specific job done
Flat rate
The goal of this is to receive the right parts, quantities, delivery and price
Purchasing
Usually a guaranteed purchase price
Price quote
A price quote which means you pay that exact amount
Firm quote (time bound)
P & D meaning
Price
Delivery: Length of time necessary for the parts to arrive
Once you know the part you want, make one of these
A requisition form (staple price quote to it)
A legal offer to purchase
Purchase order (supplier fills order upon receiving this)
If the part is not in stock from the supplier, they order it from their supplier and the part is considered _______
Back ordered
Explains whats inside the package
Delivery slip (can be invoice)
Some suppliers use delivery slips as their _____
invoice
A request for payment
invoice
When you buy international parts, make sure they are
CSA approved (Canadian Standards Association)
Three types of sourcing
Sole: Only one supplier available
Multiple: More than one supplier for an item
Single: Choosing only one source even when other sources available
This is included in a cost estimate and determines who pays for shipping and who is responsible for the goods during transit
Free on Board (freight on board)
Increasing production time between overhauls is the primary purpose of this
Preventative maintenance (includes minor work done on a regular basis to prevent trouble)
Non-destructive Testing is this type of maintenance
Preventative maintenance inspection
A program of monitoring, measuring, analyzing results to predict wear rate and expected repair schedule
Predictive maintenance (a baseline is required)
These checks and maintenance are performed at regular intervals regardless of machine condition
Preventative maintenance
A method of repairing machinery once it no longer functions properly
Reactive (breakdown maintenance)
The true cause of failure
root cause
This is used in departments where a computer system has not been adopted
Resource library
three methods of accessing information
Resource library
computer
online
a software program that maintains and manages a database of information about an organizations maintenance operation
Computerized maintenance management system (CMMS)
Used for maintenance departments to operate more efficiently
The impact on safety of the machine and the product if the work is not done and the potential costs
Impact analysis
Two ways of scheduling and planning
Bar (gantt) charts, Arrow diagrams
In the arrow diagram the ___ is the starting point and ___ is its completion
Tail - starting
Head - completion
The 5 principal components in CPM
- Arrow Diagramming
- Finding the critical path
- Evaluating the resulting program
- Scheduling activities
- Reducing project time
This is a well planned, documented, and managed engineering approach to the start-up and turnover of facilities to the end user
commissioning
Stages of commissioning
Pre commissioning Setting to Work Inspections Testing Turnover
Pre-commissioning activities
Site Acceptance tests (SAT)
Factory Acceptance tests (FAT)
Setting to Work adjustments are needed ____ to energizing the system or full startup
Prior (could be factory rep start up, calibration)
Inspections are usually _____ confirmations
Visual
This is needed to on what was installed to ensure the equipment or system operates as specified and required
Testing
The project is not fully commissioned until this is completed
Turnover (Training, project closeout documentation, commissioning documents)
The first step in implementing a commissioning plan
Planning
Commissioning minimizes ________
punch lists
What should you do before estimating
have a detailed plan of what is required
An inspection of a machine should include
quantifiable data
the process used to develop a course of action
planning
a description of the work requested
work order
9 key elements
- Planning
- Mechanical completion
- P&ID checking
- Pre-commissioning
- Commissioning
- Start-up
- Initial operation
- Performance test
- Post commissioning
