crew scheduling
TRANSCRIPT
CREW SCHEDULING “a perspective to manage crew cost”
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
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
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
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.

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
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
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
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
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.
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 [email protected], [email protected], or [email protected]
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
