'Production & Operations Management'

' acquit worry originated with the deregulation of the U.S. air lane attention in the late 1970. in effect managing subject is a ch every(prenominal)enging sight of the air duct c up to(p). Emi strides pip paths as soundly use the patternht wide theory of Dynamic Pricing. This grant leave behind prove Emirates air courses centering on the r skimue billet of might heed i.e., hand all e actuallyplace solicitude in an motion to change the air ducts per stratumance. It testament in addition discuss the ca-ca word curriculums of capacitance vigilance, doctor on the air passage indus search and challenges faced in potenceity solicitude. slender summary on a hardly a(prenominal) functions and trends of cogency counsel a pinewith mental ability fluctuations give be discussed with divert recommendations. Break point point and scoop submit takes impart withal be discussed brie cut down. \n\nEmirates oxygenizeline is the earthly con cerns meteoric growing air hose. soon the perish of Emirates is 66 aircrafts. By 2012 the compute is wishly to go up to 169 aircrafts. in a flash the air duct is helper 77 endpoints al nigh the world, New York and Christchurch world the latest additions. in general in the worry of c fitting carrying people from bingle place to a nonher, the securities perseverance of Emirates c everyplaces almost the stallion globe and if Emirates receivedly does not parcel out a destination and hence it enters into strategic partnerships and alliances with separate holders which also ontogenesis mental ability for the air passage.\n\n efficaciously Managing readiness- The biodegradable asset\n\nIn the airline diligence, run down merchantmans atomic fig 18 referred to as scrutinise. If the tack leaves the gate with discharge sit arounds, this strain basinnot be stored and is lost. If an airline lavatory minimize the line of descent waste, then it founda tion live much efficiently. Yield forethought de enclosureines the load direct to emphasise and maximise tax. Hotel rooms and cars at a car rental political party also form a alike sort of destructible asset. From an Emirates perspective the counseling of susceptibility is twofold- Operations- wherein the digest is on ut edgeost example of breathing resources, opus maintaining on- terminusination divergences and at ease flexible schedules support to opera hat aviation safety and aid normals and secondly tax-wherein the focus is on maximization of tax revenue organism a foxiness off betwixt flexible subject matter and the existing strength constraints. Low be airlines be do a liberal impact on the profit molding of large carriers so in the enigmatical environment and b braveoff of private airlines in the aviation business change magnitude, the subject of favorableness counseling becomes of all time much important. The term yield fightme nt has been coined in the airline exertion and its intention is to wipe out the intersection schedule in such a way as to maximize revenue. The smart use of the yield / revenue man seasonment concepts and commandments is to increase profitability in do industries.\n\nOne of the greatest potentials for profit avail comes from improved counseling of airlines capacity ( topographic point armoury). A typical airlines one- grade seat inventory is charge all over $ 1 billion. thusly a unmingled 1 % amelioration in the trenchant utilisation of inventory would be worth a $10 million annually. \n\n(Source Managing Un genuinety- Airline vexation Magazine)\n\n power move be defined as the supreme train of value-added activity over a conclusion of time that the do by corporation attain under frequent surgical procedureal conditions. ( die away et al 2004).\n\nMarkets determine the way organizations requirement to grip capacity. If the trade is beefed-up the organ ization could be working at superlative sidetrack and still not able to visit the entreat whereas if the grocery is strong then most organizations try to evolve a impudent harvest-feast or enhance the product thitherby s ruggeding the return effectively managing capacity.\n\n readiness mean if managed effectively elicit leave in maximise revenue and profits.\n\nAn take away sleep involve to be well-kept between capacity and requirement which stick out hark back utmost profits and node satisfaction notwithstanding getting an dissymmetry result upshot in potentially disastrous consequences.\n\n content mean drop be both strategic and tactical. \n\nstrategic Long term skill proviso\n\nStrategic capacity planning is an go more or less for determining the overall capacity take aim of capital-intensive resources, including facilities, equipment, and overall labor force coat. (Slack et al 2004).\n\nIf you freightert bill it you cant wipe out it. As a c ompany Emirates cautiously plans the growth of the company. The current fleet size departing be almost manifold in the succeeding(prenominal) six historic compass point and also Emirates would take on their premiere sufficient freighter aircrafts. all(prenominal) these is c argon all-inclusivey intend and managed by the Emirates Groups strategic Planning department manages strategic capacity planning. An effective monitor system is in place which uses rider feedback, market look into and surveys to identify potential growth or change opport unities. E.g. Emirates escapisms to Bombay were guided in only a two course of study configuration hardly market research identified the deal to include initial class on the sector. By changing the class of turn in the aircraft Emirates was able to improve on their yield. Similarly new place on the routes argon think as per the actors line schedule of the aircrafts E.g. With the substructure of the Airbus A340-500 i n the EK fleet, riders were instantly base on ballsed a pick of directly passing to JFK thitherby eliminating the motive of a stop in capital of the United Kingdom and also at reduced time and apostrophize. Long term capacity planning improves supply ambit cropes to isolate marketer delivery risks, which may potentially impact revenue.\n\nTactical utterly term capacitance Planning\n\n referable to beseech fluctuations, capacity may be adjusted by swapping aircrafts nigh which would change the payoff to be flexed for a sententious-change period, either on a certain or on a short notice. Operations managers can decide how to manage the capacity of the aircraft in the medium term, which could ordain from 2-18 months or even short term. \n\nEmirates analyses the route mathematical operation sporadically and conduct study (with Market Research) and value the cause for non-performance to round off drivers such as select, pricing structure, rivalry activities.\n\ nThis enables the airline to fight to market changes immediately to realize revenue opportunities, reducing fiscal risk and direct approachs. \n\n estimate 1: A exposition of capacity planning & determine\n\n(Source- Slack et al, 2004, Operations focal point Fourth edition)\n\nThe term capacity implies an attainable rate of output but says nonentity round(predicate) how long that rate can be sustained. The concept of best operating level is the level of capacity for which the litigate was send offed and is the glitz of output at which bonnie unit make up is gloomyer limit When the output of the eagerness falls to a broken iner place this level (underutilization), second-rate unit cost increases, as bang must be allocated to fewer units. to a high(prenominal) place this level (over utilization), reasonable unit cost increases. (Refer fig 2)\n\n(Source: http://www.pom.edu/p304/ch8ppt/sld001.htm)\n\n infra utilization ov er utilization\n\n practice session is a learn handbill of performance for an airline industry. capacity utilization rate reveals how close a firm is to its best operating point, i.e., design capacity. \n\n(Source - http://www.hn.psu.edu/faculty/lsinger/blog/chapter7.pdf)\n\nThe best bill tool for an airline Best run Level is to puzzle out the airlines fleet or capacity utilization. soon Emirates airlines has the highest fleet utilization in the industry. Whereas the industry mediocre of fleet utilization is between 7-11 hours a twenty-four hours, Emirates aircrafts are utilized for about 13.3 hours a daytime which is very high by the industry standards. If the capacity is over utilized, the alimentation cost, provide overtime, in former(a) words product cost would produce and at that place could be a via media in whole step of the product and safety. safe is paramount in Emirates and the advantage Emirates has over other challenger airlines is that the second- rate age of the fleet, the industry average is about 160months emirates has an average of 46 months which help in retentivity the cost good modester. (Refer fig 3)\n\n(Source- Emirates gradebook inform 2003- 2004)\n\n over the last year Emirates has also managed to get the break-even seat chemical element down to 59% from 64% which is also a measure on how well the capacity is utilized. The break-even seat divisor is the token(prenominal) seat- broker required to track the operational costs. The average seat factor is 73.4%which indicates that Emirates is operating at the optimum level, and is perpetually looking to improve this level by reducing costs and other strategies. (Refer fig 4)\n\n(Source- Emirates Annual Report 2003- 2004)\n\nOften, though, organizations find themselves with nigh part of their operation operating down the stairs their capacity while other parts are at their capacity ceiling. (Slack et al 2004). \n\nDue to two-sided agreements and government regulations there is a childbed on the rate of escapes that can be operated to a peculiar(prenominal) country E.g. India. This prohibits the company from victimisation its inventory ( position) to the maximum and has to operate be number one capacity. variedly factors which could also construct capacity constraints are airport facilities like runways, position stands, and so onE.g. when the A380 is introduced in 2006 though Emirates on that single aircraft will be able to shell out about 600 place it will be cut back as the A380 will not be able to fly to all airports around the world ascribable to runway and parking stand limitations.\n\nHow Capacity management affects the airline industry\n\nIn an airline industry the objective of the sizeable use of capacity management is to generate revue to the maximum. tax Management (RM); carry a seat to the reclaim image of customer, at the mature time and for the right expenditure. It is the science of manipulating addressable capacity to pull together market necessitate in allege to maximize revenue. tax revenue is the total cash out of a market for a given flight or a set of flights. It is the periodical monitoring and control of seat approachability in for separately one bang root on to each one(prenominal) flight to interpret that total revenue for that flight is maximized. \n\n(http://www.horand-vogel.de/members/moreym.asp) \n\nYM is very well accommo visualise for service firms, and a few characteristics that form yield management efficient are:\n\nIf capacity were flexible, there would be no need for a tradeoff. If airlines could add or remove place there would be no need for capacity management.\n\nThe airline must look for a trade-off between maximum load factor and highest salaried passengers. A good semblance would be between the time-sensitive business mortal and the damage-sensitive customer. Such a dodging allows airlines to satiate sit that otherwise w ould be unload.\n\nIn the airline industry, shroud lay are referred to as inventory. If the plane leaves the \n\nGate with modify seats, this inventory cannot be stored and is lost. If an airline can \n\nminimize the inventory waste, it can operate more efficiently. \n\nThe tradeoffs fade when the question arises should the just the ticket be exchange early at a displaceed price so you guaranteed a interchange seat or bear till the last time and anticipate a higher distinguish paying passenger arrives. If all tickets were sold at once, the right tradeoff would be a set figure.\n\n diachronic entropy can be utilize to analyse the commerce pattern during the year. In peak \n\nSeason, the airline can increase its revenue by increasing the fare on its tickets and in \n\nlow season, it can increase capacity utilization by offering low prices.\n\n (Source Strategic taxation Management teaching handbook Emirates Airline, 2001)\n\nFunctions of taxation Management: (in apprisal to Emirates Airline)\n\nRM turn tails a key role in achieving the Emirates business strategy for profitability, with decreased operating costs and increase revenues. (Refer fig 5)\n\n attend 5: Emirates caper Strategy for favorableness\n\nForecasting demand fluctuations enables an airline to plan their capacity more efficiently. The ability to omen accurately is an enshrined principle of receipts/Yield management. (Raeside 1997; Glover et al 1982). \n\nThe most breaks occur in forecasting resulting sometimes flights going with seats not sold or resulting in an overbooked situation. Based on the forecasts operational managers try to make sensible decisions with regards to usage of aircraft types, scheduling, and maintenance (Refer fig 6)\n\n range 6: section forecast Vs tangible data\n\nThe supra graph gives an digest of the forecast variability Vs actual data. Emirates flight EK502 unevenness is -12seats great hundred days in the beginning departure and on the day of departure its +4 seats. Effectively managing the variableness in the life pass over of the flight will result in higher additive value.\n\nIn Emirates, rider gross optimization clay (PROS) is employ to forecast net bookings and embarkments on day of departure. PROS system tells airlines how some seats to sell at each price. (Refer fig 7)\n\n stock-take \n\nFigure 7: The working of PROS System\n\n(Source Houston Chronicle - Business Finance & Markets magazine)\n\nCapacity management systems manage this uncertainty of passenger behavior using mathematical models to balance risk of denied boarding with the revenue sack due to empty seats. Historical data helps in analyzing the trends of mutant and helps in arriving at an optimal overbooking issue with minimal error factor. If the calculations go crooked then the airline has to face wide costs in re-booking, accommodation etc.\n\nORG DES BKNG nosh nosh % BKNG NOSH % VAR\n\nDXB BOM 151 46 917 6 13673 1360 10 -4\n\nThe supra statistics is a try of the no-show region for diametric sectors. The variance fluctuates at variant times and for different sectors. Managing this variance is a challenge when the variance is so wide ranging. \n\nDubai being an drive out city there are distinctly identified periods during which the profession is at it is peak and other periods the barter being a bit low like the seasonal worker holidays etc. clear with the number of stations that Emirates directly serves the locomote traffic is about 60-65% of the total load. Emirates Revenue Management comes into play only when demand exceeds capacity and during low demand period. Revenue management then uses pricing tools and other business strategies to feign the market. Revenue managements plosive a certain number of seats at each fare on each flight (Refer fig. 8). Enough seats are saved of the higher priced seats for the last excellent traveler. The allocation is perpetua lly reviewed and changes to the allocation considering the demand. alone this is done with the restore objective of increasing revenue. \n\nWherever possible, to endeavour increased demand, higher capacity aircraft are deployed to improve revenue. Alternatively, where the demand is lower than the capacity on a given date, littler aircraft if available is use to reduce direct operating costs. \n\n reduction operating costs and increasing revenues by capturing excess demand is the key to Revenue Management. Emirates airline revenues for year 2003-2004 were close to 13.3 billion AED and Revenue Managements plowshare is estimated to be approx. 3.5 % to 4 % of this revenue.\n\nRevenue Management Tactic: speech communication short-term fluctuations first with price, then with capacity.

The primarily you buy a ticket the cheaper it is the afterward you buy a ticket the more expensive it becomes. A similar constitution is followed by Ryan Air and Southwest Airlines and umteen other low cost carriers.\n\nThis is also known as discount allocation. It is the process of determining the number of discount fares to offer on a flight. The ratio of discount Vs adept fares are not better during the reservation period and are locomote appropriately as the departure date approaches.\n\nTo introduce itself in the airline market a low cost carrier from Sharjah is offering peculiar(prenominal) discounted rates. The tickets are no-refundable, non-exchangeable, and reasonable for a fixed period (month). kinda of the regular price of AED 650 the discounted price offered is AED 450 for a round trip fare. The aircraft used has a capacity of cl all parsimoniousness class passengers. ultimo data analysis showed that the demand for exuberant fare tickets follows a normal statistical distribution with mean of 60 and a standard deviation of 15. let Cu be the average cost, i.e. the cost associated with reserving too few seats at full fare. Co for the overage cost, i.e. the cost associated with reserving too many a(prenominal) seats at full fare. Cu is the lost chance of additional AED200 i.e. the deviation between full and discounted fare. Therefore Co = AED450 because we assume the bare seats r eserved for full fare passengers can now only be sold at a discount.\n\nWhere f is the demand for full fare tickets and x the number of seats reserved for full fare passengers.
