industry where good tactical direction is the key to long term sucess and

endurance. The air hose industry is a premier illustration of a market where cutthroat

competitory activity is the position quo. Airlines that survive in this environment do so

through the apprehension and continued betterment of the manner in which tactical

direction undertakings are addressed. Success is dependent upon making all of these

undertakings good including demand prediction, logistical scheduling, selling and

production. The cardinal point to retrieve is that since American Airlines is a tactical

entity, its cardinal country of concentration is equilibrium care. A continual enterprise

must be made to fit supply closely to demand, particularly awaited demand. If

it is non likely that production can be amended to more closely match demand, so

publicity should be used to affect demand.

American Airlines dedicates big sums of clip and resources to the types of

installations necessary to back up the tactical direction undertakings noted supra. This

study is an effort to exemplify the types of information system demands of

each undertaking in the tactical direction sequence, every bit good as describe some of the

systems and methods used by American Airlines. In add-on, this study offers some

off the shelf options, where they exist, which could manage many of the same

demands, albeit on a smaller graduated table. Since demand prediction is one of the key

drivers of production, i.e. how many merchandises a house should provide, this will be the

first direction undertaking to have consideration.

All houses engaged in activities as a tactical entity will, in some signifier or another,

effort to acquire a grip on expected demand for their merchandises within a certain

future clip period such as a hebdomad, month, one-fourth or twelvemonth. The chief thing to bear in

head is that this is a tactical environment and, aside from any Earth shattering new

developments or dazes to the bing environment, prognosiss for expected

demand/maximum-likelihood portion of market may be made with a just grade of

truth with small discrepancy. There are several cardinal points that are of import to this

procedure which must be considered when doing a following period prognosis of demand.

These points include, but are non limited to, intelligence refering activities of

rivals, market projections for the industry by industry insiders/analysts, and a

great trade of historical informations.

Competitive intelligence is a parametric quantity which attempts to add subjective

background to the environment in which demand prediction is carried out.

Information comes from a assortment of beginnings such as secondary information gathered

from written beginnings, direct observation, and from rivals themselves through

imperativeness releases, industry assemblages and trade diaries. This information provides

some indicant of what the competition programs to make every bit far as pricing, new merchandises,

publicities and distribution/sales. This information has a double intent since it may besides be

used within theoretical account based eventuality be aftering when direction scrutinizes

competition in an attempt to bring out developing menaces and chances.

Experienced tactical directors have the valuable ability to integrate this type of

information, which is non easy quantifiable, as a complement to the numerical

facets of demand prediction. However, this is non to state that there is no

information system demand for this input into the demand prediction procedure

merely because it is hard to absorb into an nonsubjective, quantifiable signifier. On the

contrary, a database should be set up in the context of an expert system to incorporate

information gathered on rivals. It must be readily accessible, updated and

accurate in order to help tactical direction in this procedure.

Another input point for demand calculating comes from aggregative market

projections. These types of analyses are readily accessible, largely in the signifier of

secondary information found in trade diaries and economic publications. Airlines

and transit in general comprise a big industrial group within the economic system

of the United States and, consequently, there is a big involvement in its economic hereafter.

Wall Street securities firm houses and other fiscal houses are glorious with analysts,

some of which are charged with the undertaking of tracking the air hose industry? s yesteryear

economic public presentation, every bit good as awaited hereafter projections. All of this

cognition is available from many beginnings and, once more, wise tactical directors will

take the clip to integrate it. System installations required for this type of support for

demand prediction are databases which can incorporate quantifiable economic

information. Since this input to demand prediction is quantifiable, a database with

analytical public-service corporations for ranking and analysing stored economic projections and raw

informations are used. This installation may besides be presented to direction in the pretense of a

dressed up adept system incorporating determination tabular array concepts which will let them

to set many demand calculating parametric quantities in order to do the most accurate


Arguably the most of import input into the demand calculating procedure is a house? s

existent historical information from its ain internal records beginnings. Historical gross revenues informations may

be thought of as the most reliable and accurate input into demand prediction

since it is derived by the house itself instead than geting in a 2nd manus manner from

beginnings outside of the organisation. Historical gross revenues informations is helpful non merely in

developing a demand prognosis, but is besides used as a cheque against station production

public presentation when the clip arrives to compare existent demand to the prognosis. This

information will probably come from another monolithic record maintaining database which

records gross revenues minutess from the point of sale. For American Airlines, every bit good as the

remainder of the air hose industry in general, this demand is served through a

reserve system of some sort. The reserve system must be capable of

managing questions, informations influxs and other types of processing from 1000s of

nodes. Dummy terminuss, which merely display information, will non be sufficient to fulfill

reserve system demands, and any execution will affect connexions

and terminuss designed to transport bipartisan traffic. Extra treatment of reserve

systems, including specifically what American Airlines has installed, will follow subsequently in

this paper.

After fulfilling system demands for bring forthing and managing inputs into the

demand calculating procedure, the existent prognosis derivation may be viewed as

slightly mechanical. The chief direction determination at this point is finding

which type of probabilistic instrument to utilize with which analytical public-service corporation to give the

most accurate consequences. Some tactical directors may even necessitate an expert system

that does nil more than help them in choosing the proper mathematical tool to

address the prediction procedure. There is an array of probabilistic techniques that can

fulfill this direction demand including least squares arrested development analysis,

leaden scenarios, Markov-based stochastic projections and others. Many tactical

directors may utilize a combination of these installations to get at a prognosis with which

they feel satisfied.

A cardinal point to bear in head when discoursing demand calculating for a tactical entity

is that it is cardinal to two of import facets of the house. The demand prognosis is

viewed foremost as the primogenitor of the house? s production for which it is the chief,

direct input. However, it is besides an index of the general tendency of the house? s

grosss over clip. A prognosis whose extrapolation to the following period indicates a

diminution in grosss may be an early warning of something novel in the industry or

declarative mood of a paradigm displacement toward a new epoch. This facet of troubleshooting will

be discussed more at length in a ulterior subdivision concerning demands for procedure


The demand prognosis sets the phase for the following direction undertaking & # 8211 ; logistical

scheduling and its accompanying system demands. Logistic scheduling is

the undertaking charged with roll uping proper sums of the factors of production in

the proper topographic point at the proper clip. The four factors of production ( stuff,

finance, equipment and work force ) have certain input demands which

find the sums of each factor to use to the production procedure. Each of

these inputs will ask the usage of some type of information system to help

tactical directors in allotment of these factors to production. One of the first inputs

into logistical scheduling is the supply agenda, which is the chief determiner of

the sum of merchandises or services offered by a house. For the air hose industry, supply

agendas manifest themselves in the signifier of the magnitude of flights offered to the


A demand prognosis is the chief force behind the supply agenda, but other

normative microeconomic factors play an of import function in its composing. One of

these factors, optimum graduated table of works, exerts a direct relationship against the supply

agenda and, for American Airlines, consists of the optimum terminal/gate layout at its

busiest hub metropoliss. The end of proper terminal design is to optimise the figure and

size of the composites which converge on a hub terminus throughout the twenty-four hours. A

complex consists of a group of inbound flights which land within proceedingss of each

other and take-off within proceedingss of each other. This is the really bosom of a hub and

radius system which allows a big figure of flights due to the figure of possible

connexions in the hub. Inbound riders from many metropoliss will all get at

about the same clip, disembark, and do connexions to many outbound

flights which leave within proceedingss of each other. This occurs many times throughout

the twenty-four hours and the system demand for work outing this job and optimising the

operation is available in the signifier of CADD design Stationss.

CAD/CAM design workstations may be used to work out terminal optimisation jobs

and let applied scientists to imitate the capableness of the terminus to manage certain

scenarios. This is, in fact, precisely what American Airlines did when it was seeking for

the optimal design for its $ 80 million enlargement of its chief hub in Dallas/Fort

Worth in 1983. This simulation theoretical account was used by senior direction to help them

in their determination on the best design to manage the coveted flow of traffic in the narrow

operational clip restraints necessary for the hub to work. In add-on to optimising

the terminus layout, the system was utile in optimising other related countries. The

system/model was used to find dynamic gate assignments in order to

minimize luggage handling costs and rider holds. Another by-product of the

theoretical account was a utile algorithm designed to automatically plan and update marks

for directing riders around the terminus. The functional installation was even used to

find the best layout for short-run parking in the face of expected additions in

rider traffic.

Though optimum graduated table of works through optimum terminal design is an of import

facet of American Airlines? supply agenda finding, the most of import portion

of the supply agenda lies in finding the figure of flights to and from certain

finishs. For American Airlines and most of the air hose industry, flight programming

is non a simple affair. Flight programming is one of the most of import undertakings

performed by tactical air hose directors because it is cardinal to where and how the

factors of production are allocated. The proficient system demands are countless,

and they must run into the dashing job of properly scheduling 1000s of

flights per twenty-four hours between 100s of domestic and international finishs utilizing a

fleet of over 500 aircraft. One chief demand is for a system capable of analysing

past flight offerings in hunt of forms of overbookings and empty flights in order

to set agendas to better meet forecasted demand.

Technical demands for an air hose programming system would include a information base

construction to house the organic structure of past and present agendas from which directors

could take when composing a new agenda. The job is compounded since

air hose agendas are determined months in progress. In add-on to utilizing

optimisation techniques, the system requires certain adept system installations such as

& gt ;

determination tabular array concepts to help in agenda development. Diagnostic remedial AIDSs

are used in order to descry constrictions in the proposed agendas where forms of

frequent overbookings are happening. In add-on, remedial systems capable of

offering solutions by reshuffling proposed agendas provides valuable information to

flight programming directors. Historical information is fed into the scheduling theoretical account from the

database incorporating past agendas and informations refering past parametric quantities which

influenced those agendas. The system takes this information and combines it with the

demand prognosis in order to develop a preliminary agenda. The procedure requires

diagnostic and remedial systems to optimise the agenda so that the expected

demand will be met in the most efficient mode possible.

Even with an optimum agenda in topographic point, there will ever be breaks due to

conditions and deficits of planes and crews ; therefore coercing scheduling directors to

invariably rearrange flights. Before 1991, this was a complex undertaking for American

Airlines since starters had to scan informations from many different mainframe databases

in order to acquire a grip on pull offing day-to-day flights. The agenda was invariably

being reconfigured to run into awaited external obstructions such as holds due to

inclement conditions. In 1991, nevertheless, American Airlines invested in a new system

known as Smalltalk which made agenda care easier and more efficient.

Smalltalk uses of object-oriented programming techniques in order to maintain flights

running swimmingly. The starter merely clicks on an object stand foring a flight

and, when he changes the flight, the system automatically updates other objects

( flights ) in the system in order to propagate the alteration throughout the full

system. In fact, it merely took three coders eight months to compose the plan

which contained merely two mistakes.

Once an optimum agenda has been developed through simulation and optimisation

techniques, the following measure is to set up the factors of production in order to bring forth

adequate merchandises and/or services to run into prospective demand. Since work force

costs equal over tierce of all outgos for American Airlines, it is the first

factor to have consideration. Manpower for an air hose takes on many signifiers ;

nevertheless, about all of the employees of American Airlines can be classified into one

of three different wide classs. The first class represents the aircraft crew

whose responsibility Stationss are on the aircraft: pilots, co-pilots, sailing masters and flight

applied scientists, every bit good as the cabin crew or flight attenders. The 2nd class is

referred to as care workers, and they are the people that maintain the

aircraft, which includes anything from refuelers to engine mechanics. The concluding

categorization includes all of the ramp workers such as luggage animal trainers, fining

forces and office workers. By far the most hard class to apportion within the

work force group is the aircraft crews.

Manpower demands for air hose crews are derived from the flight agenda. The

chief end for crew schedulers is to develop a agenda for the full following month

which will guarantee that all of the approaching flights for the month are decently staffed.

Flight crews at most air hoses command by senior status for the flights that they will wing in the

following month and crew schedulers develop flight bundles for them. The flight

bundles are known in the industry as bidlines. The bidlines in bend are composed of

flight sections called trip couplings, and they customarily cover a one to three twenty-four hours

clip frame. Intensifying the job for the schedulers are FAA and brotherhood work

regulations designed to minimise the hazard of accidents ensuing from crew weariness.

Therefore, the chief demand of a coevals and optimisation system is that it is

able to happen the optimum set of bidlines ( i.e. the set which yields the lowest cost )

which maximize the use of each crew member, equally distributes flying clip

among the bidlines and screens every scheduled flight.

The belongingss inherent in the crew scheduling quandary require an expert system

design. The first portion of the system uses manpower lading algorithms, the current

and old month? s agendas ( from assorted databases ) and optimisation

techniques in order to develop the set of trip couplings, which would adequately cover

all scheduled flights for the approaching month within FAA and brotherhood work guidelines.

The trip coupling procedure is made even more burdensome because American Airlines

operates several fleets of different aircraft and most pilots are trained to wing merely one

type. The undermentioned diagram illustrates the demands for a crew assignment


Beginning: & # 8220 ; Recent Progresss in Crew -Pairing Optimization Techniques at American

Airlines & # 8221 ; , Interfaces, Jan-Feb. 1991, V.21, p. 66.

The 2nd portion of the system takes trip couplings and bidlines and analyzes them

( capable to optimization techniques ) in order to constantly hunt for a solution

( agenda ) which yields the lowest cost for flight crews possible for a given flight

agenda. The system will continually runs through loops of the optimisation

modus operandi and, if the set of bidlines it determines is more optimum than the last, replaces

the former with the latter. Naturally, the faster the loop velocity of the system,

mainframe or LAN, the Oklahoman the system arrives at the optimum solution. The

following flow chart describes the subproblem loop methodological analysis.

Beginning: & # 8220 ; Recent Progresss in Crew -Pairing Optimization Techniques at American

Airlines & # 8221 ; , Interfaces, Jan-Feb. 1991, V.21, p. 67.

American Airlines every bit good as 9 other air hoses and a railway, makes usage of a system of

this design and it accounts for an one-year cost nest eggs of $ 20 million.

Scheduling for incline workers, gate crews and ticket counter forces is less

composite and besides dependant on the flight agenda. Scheduling systems for these

forces are less complex but besides involve optimisation techniques in order to

arrive at the lowest cost for labour while guaranting that reaching and going times at

each gate are as near together as possible. Manpower lading algorithms are used

to delegate more forces to cover peak times and less forces in each station for

off-peak hours during letups in the hubs. Office forces and fix crews normally

work on a regular basis assigned hours, in the absence of work stoppages and/or exigencies, and are

rather simple to agenda. It should be noted that Human Resources and Payroll

Departments need to keep a database incorporating each employee? s work record,

salary history and personal information in order to maintain path of 1000s of


The following factor of production for consideration is the equipment to be used in

production to run into forecasted demand. As mentioned above, American Airlines

operates two big fleets of aircraft, every bit good as several smaller fleets. The chief aircraft

types are the McDonnell Douglas 80 and Boeing 727. The smaller fleets are

comprised of Douglas Corporation 10, British Aerospace 146, Boeing 737, Boeing

747, Boeing 757/767 and Airbus 300 aircraft. A peculiar flight or path might impart

itself to a peculiar type of aircraft which best lucifers features of the flight. All

air hoses have an highly high capital/labor ratio which is declarative of the big

dollar outgos made for aircraft. The air hose industry is a mature, tactical

industry and, hence, lends itself to a capital intensive position giving a high

capital/labor ratio. Fleet assignment jobs lend themselves to integer additive

scheduling, which is a good manner to get at a solution.

Unfortunately, the best aircraft for a certain flight may non be available because of

care routing, flight agenda breaks due to inclement conditions or even

pilot work stoppages. Aims that must be maximized include use of the most

efficient types of aircraft and finding the mix of aircraft to give the lowest

operating costs. Other operational restraint parametric quantities the system will be required

to cover with include the fact that certain flights will necessitate to utilize certain aircraft types,

bounds on figure of aircraft staying overnight at each station and the figure of

slots available per airdrome per twenty-four hours. The determination theoretical account uses the additive scheduling

methodological analysis and agendas two or more fleets to a flight agenda at the same time in

order to guarantee the handiness of aircraft to run into demand. The flight agenda,

handiness of aircraft ( which aircraft to utilize on a peculiar flight ) and gate handiness,

every bit good as other parametric quantities, are fed into the system. It must be ensured that each

flight and its undermentioned connexion, known as a bend, are served by the same type of

aircraft. Equipment continuity is really of import to the theoretical account? s unity and a bend

can non utilize two different types of aircraft. Each aircraft must be kept path of and

counted within the system so the theoretical account will cognize whether an aircraft is available. An

aircraft can non be assigned to two different flights in different countries at the same

clip. In add-on, a proviso or accommodation variable must be made to the theoretical account

when the station is non balanced. An imbalanced station occurs when there are more

reachings than goings or there is an instability between the aircraft types used. By

utilizing determination AIDSs and proficient public-service corporations, the theoretical account will get at the optimum fleet

assignment through uninterrupted loop much the same as the crew bidline theoretical account

for flight crew scheduling described above.

The 3rd factor of production which tactical directors must develop system

demands for is in the country of finance. Aircraft and other related equipment

purchases are a big portion of the capital budgeting demand of an air hose the size

of American Airlines. An issue which is cardinal to the capital budgeting program for

aircraft is the antique determination, & # 8220 ; Should we rent or purchase our aircraft? & # 8221 ; Leasing and

purchasing both have really existent advantages and disadvantages over each other, and

hence this type of determination tends to be nonsubjective based on whichever method will

accomplish the least hurt to the bottom line. Consequently, there are several really

well-developed methods employed by fiscal and accounting directors when

measuring capital budgeting programs. These popular methods include net nowadays

value, internal rate of return, payback period and accounting rate of return.

Whether or non to set about capital budgeting is non an issue for a capital intensive

house such as American Airlines. The key job to be solved in capital budgeting

so becomes which analytical theoretical account is the best application for rating of assorted

scenarios such as which aircraft to purchase, when to purchase and whether to buy them

or rental from the maker. A capital budgeting system will has to be a proficient

and/or analytical public-service corporation in the signifier of an expert system to help tactical directors in

capital budgeting. One of the chief inputs into a capital budgeting system is the

forecasted incremental hard currency flows per clip period attributable to the prospective

undertaking. Data for this demand comes from historical gross records for the

aircraft in inquiry. A rental scenario and a bargain scenario can be run for each

prospective capital budgeting program in order to find which undertaking will most

increase the net incomes of the house. Algorithms to execute the figure crunching can be

programmed into the system without much problem since these are good developed

theoretical accounts. Again, the chief intent of capital budgeting is to move as a determination assistance to

indicate which analytical methods/models will turn out to be the most judges of a

undertaking? s viability. After measuring the undertaking, the system should help direction in

where and how to obtain the needful financess to continue with an acceptable capital


The concluding factor of production and its attendant information installation demands to

receive consideration in the study before discoursing production is the stuff

facet of the house. For an air hose, stuffs for production can include, but are non

limited to, points used in bringing of services such as aircraft parts, drinks served

on flights, in-flight repasts, office supplies and many, many more. The chief aim

is to efficaciously find the right sum of supplies and where to buy

them at the lowest cost. Another end is to minimise stuffs transporting and managing

costs through a speedy response system between air hose and providers akin to the type

endorsed in The Virtual Corporation. Inventories of aircraft fix an
