What is a model?
A model is representation of a process. Usually, a mathematical modeling takes the form of a set of equations describing a number of variables, and we distinguish between continuous in space; time and discrete models, whose variables vary discontinuously.In practice models are formulated as differential equations,both ordinary and partial. In formulating continuous models, there are three main ways of prescribing governing equations.The classical procedure is to formulate exact conservation laws.The laws of mass. momentum and energy in fluid mechanics are obvious examples

Procedure of Modeling
Problem identification Mathematical modeling begins with identification of a problem.There is something we don't understand, a phenomenon that requires explanation, and we begin by trying to identify a plausible mechanism.Some times this is quite straight forward.For example, consider the exasperating effect on the motorist of traffic jams on motor ways.You drive along until quite suddenly you hit slow moving wall of traffic.You then move at a snail's pace until all of a sudden the road is clear and you can drive freely. To formulate a model we require laws....

FULL-SERVICE CARRIER (FSC)
A full-service carrier (FSC) is defined in this study as an airline company developed from the former state-owned flag carrier, through the market deregulation process,into an airline company with the following elements describing its business model
 * • Core business: Passenger, Cargo, Maintenance.
 * • Hub-and-spoke network: This has as its major objective the full coverage of as many demand categories as possible (in terms of city-pairs) through the optimization of connectivity in the hub. This item will be presented in-depth, in
 * • Global player: Domestic, international and intercontinental markets are covered with short-, medium- and long-haul flights from the hubs to almost every continent.
 * • Alliances development: No individual airline has developed a truly global network.Thus the network is virtually enlarged by interlining with partner carriers and become part of multi-HS systems.
 * • Vertical product differentiation: This is affected through in-flight and ground service, electronic services (Internet check-in) and travel rules to cover all possible market segments.
 * • Customer relationship management (CRM): Every FSC has a loyalty program to retain the most frequent flyer's. The frequent flyer's programs(FFP) have became part of a broader strategy called CRM. The general purpose of CRM is to enable carriers to better manage their customers through the introduction of reliable processes and procedures for interacting with those customers. The final aim of the CRM is to enhance the passengers buying and traveling experience in order to personalize the carriers services. In this perspective, the CRM is an extra tool to differentiate the airline product.
 * • Yield management and pricing: To support product differentiation, pricing and yield management is sophisticated, with the aim of maximizing the network revenues.This item will be presented in-depth.
 * • Multi-channel sales: Sales channels are divided into indirect off-line (intermediate travel agencies) or indirect on-line (web intermediate electronic-agents);direct on-line: the passenger buys the tickets directly via the airline’s Internet site; direct off-line: the passenger buys the tickets directly via the airline’s call centre, the airlines city office (CTO), or the airline’s airport office (ATO). The FSC cover all of these channels.
 * • Distribution system: The complexity of the distribution system described above is technologically supported by external companies called Global Distribution Systems (GDSs). Among the most diffused GDSs are: Galileo, Amadeus,WorldSpan, Sabre.
