Voitsehovskiy V. Cargo flows management of a network air carrier on the logistics principles

The thesis is devoted to the issues of increasing the efficiency of cargo flows management of network air carriers on the principles of logistics, taking into account the individual approach to the rational organization of cargo transportation processes under external environment uncertainty, which allows to improve the accuracy and speed of decision making. In order to take into account information uncertainty and risks of demand reduction for carrier’s services in real time mode, a two-stage model of cargo flow management of a network carrier consisting of a nonlinear dynamic model of traffic flows and a mathematical model of operational management in the short-term time segment was formed. Models are interconnected through the use of the same input information about the external environment, in which the airline operates, about the airline itself and the exchange of information, which for the same model is output and for the other one is input. The models differ in detailing the use of information and in detailing the description of the transport process. To create a cargo flows management system for a network carrier, the method of forming integrated cargo delivery systems based on logistics principles, taking into account all components of the air transportation logistics chain on the airline network, factor influences on cargo flow and the dependency of the flight load capacity on the tariff, was improved. For the purpose of maximizing revenue at maximum loading, additional cargo flow management, continuous tonnage demand control, the use of market instruments for assessing statistics on the market and comparing it with own data, the comprehensive use of the entire network in accordance with the cargo flows management tools, the author’s approach to cargo flows management on the network of airlines was proposed. As a result of the classification of a network air carrier’s cargo flows, the existence of cargo flows available for servicing, the existing restrictions for cargo flow servicing, as well as the factors that should be taken into account when servicing cargo flows were identified. The software implementation of the task of cargo delivery by a network air carrier allowed establishing peculiarities of applying offered scientific results. vangrb solver was used to solve the problem, which in turn uses the Gurobi Optimization package. The modeling results confirmed the adequacy of the proposed models. The offered practical recommendations for the implementation of the cargo flows management system of a network air carrier enable the effective use of the models, methods and approaches offered in the thesis in practice.
