2. FACTS
Crew cost is one of major cost components in
airline industries
It is usually the second largest after fuel cost
It is more controllable than fuel cost
Savings in crew costs can be achieved through
better scheduling
3. FACTORS DETERMINE CREW UNIT COST
Benefits, work, and
rules driven by
contract cycle or
labours agitation
Hub and Spoke structure
creates extremely many
possible pairings
4. CREW SUPPLY CHAIN
Deciding
where the
fleet goes
Counting
the amount
of crew to
operate the
fleet
Hiring
people with
right quality
and quantity
Making
sure the
crew
readiness
to operate
the fleet
Giving
appropriate
task
Controlling
crew
movement
5. CREW SCHEDULING
Crew Pairing
“sequence of flight legs own by the same aircraft type,
starting and ending at the same station, called the crew base.”
The objective is to use the minimum number of resources (crew)
to schedule (cover) the complete timetable.
Crew Assignment
“the created pairings are assigned, together with other kinds of
activities, to actual crew, in compliance with the qualifications
and previously assigned activities, referred to as pre-
assignments, of the crew”
The objective is to find feasible assignments that minimize
costs without overriding crew’s quality of life.
7. ASSIGNED LINES METHOD
Simplicity
Equality between junior
and senior crew member
Low job satisfaction
Susceptible to intervention
Too many intervention
may cause inefficiency
Advantage Disadvantage
8. BID LINES METHOD
High job satisfaction if
preferred pairing is
awarded
Simplicity
Offer a transparent and
easy process to bid and
to award
Preferred pairing may
conflict with crew
members predetermined
activities
Too many reallocation
assignment
These inefficiencies also
force airlines to hire more
crew members.
Advantage Disadvantage
9. PREFERENTIAL BIDDING METHOD
High job satisfaction
Flexible pairing
Efficient
Complicated
Difficult to award all
pairing
It may take many hours
and multiple runs to
achieve the optimal
solution
Advantage Disadvantage
10. CONSTRAINT
Personnel Constraint
Time constrain
Flight time
Flight duty time
Rest time
Personnel activities
Medical check
Recurrent license
Personnel rights
Leg/flight Constraint
Qualification
Rating
Language proficiency
Company’s Standard
Standard service
Standard complement
Seniority
each flight must consist of
several crew generation to
ensure regeneration
11. RECOMMENDATIONS
In order to perform an efficient crew rotation, crew
supply chain needed to manage as an integrated supply
chain.
Every crew scheduling method has advantages and
disadvantages, thus every airlines must deeply
understand their own crew requirement to choose the
right method.
Optimizer tools are needed to set the most efficient
schedule.
Irregular operation procedure should be made to protect
optimum plan and to keep fairness among crew.
12. NOTES
Hi Readers,
Firstly, I’d like to say thanks for reading this, hope this could help
you, and I’m sorry if there is a mistake (Nobody’s perfect anyway
). If you have a question or want to discuss about this don’t
hesitate to contact my mail at lwidayanto@yahoo.com,
widayanto1986@yahoo.co.id, or widayanto86@gmail.com
I’m compiling this from many resources like airline magazine,
wikipedia, books, people’s research, articles, etc. I’d read so
many resources and it’s making me forget the “real” resources
:p. So, I’d like to say thanks to everybody who helps me making
this but unfortunately I couldn’t mention it one by one because of
that matter.
Thanks once again
