Production enterprise «Novosibirsk Aircraft Repair Plant» wants to decrease helicopter’s repair cost in order to fulfill the strategy of entering domestic aircraft repair market. It is essential to develop an integrated simulation model describing organization’s processes, which should be used to explore the opportunities of the key indicator reduction. Simulation methodology and system dynamics serve as basis for the model building. Apart from theoretical considerations, the work includes primary enterprise survey, problem statement and selection of the preferred simulation system. At the first stage of model development, cognitive modeling is performed in order to specify the system’s structure and its elements’ interrelations. Next, the simulation model is built using the selected tool. A number of subsequent experimental runs of the developed model performed within scenario planning result in identification of an optimum activity scenario. Eventually the strategic course of action is designed to provide helicopter’s repair cost reduction and thus meet the goal of the enterprise.
This article explores the possibilities of modern simulation modeling in the tasks of design and supply chain modeling as systems with structural and dynamic complexity, the study of which should be carried out taking into account multiple risk factors and uncertainties, considering and evaluating the efficiency, dynamism, flexibility and adaptability of the SC based on a variety of indicators used in logistic practice. The use of simulation modeling requires the adaptation of modern managerial techniques and approaches used in logistic practice with the technique of simulation modeling . Useful management techniques based on the use of simulation techniques in the analysis and modeling of SCs are considered, as well as methods of constructing conceptual models of the SC and analysis of the SC using simulation modeling, iterative simulation and optimization procedures for integrated research and optimization of the SC. A review of the capabilities of various simulation paradigms for analyzing SCs and a review of related scientific literature are also being conducted. It is shown in particular that process simulation modeling is effective for describing the network structure and logistic processes in the SC and is actively used in reengineering projects based on SCOR-recommendations. System-dynamic models of adaptive supply chains allow you to study the complex interaction of material, information and financial flows in the SC, to analyze the stability of the SC, to coordinate the business strategy and logistics strategy of the company. Agent-based simulation modeling makes it possible to describe the behavior, processes of cooperation, coordination and inter-organizational interaction of the participants of the SC and reconfigurable network structures of the SC.
