Object-oriented model of the market conditions: development principles and purpose

The article discusses the problem of developing a model of market conditions asa way to improve the efficiency of management tasks decision. In the beginning the significance of modelling conjuncture for solvingenterprise tasks is substantiated. The main reason is that for the optimal solutions a manager should have complete information on theproblem. However, market information required to solve managerial tasks is unknown. The main reason for its absence is the complexityof its collection. As without this information a manager has risks of taking the wrong decision, it is important to help collect suchdata. The model of market conditions allows systematizing information about the market, which a firm needs and which the firm alreadyhas, thus increasing the efficiency of data collection on the market and solutions of managerial problems in general. Then the modernexperience of creating models of the commodity markets by Russian scientists is studied. Most scientists offer to divide the marketsituation into conjuncture-making factors - the driving forces of development conditions that determine the situation on the market.Researchers are developing various classification factors, the most advanced of which are proposed by S. Svetunkov. According to him,there are 11 attributes for classification of conjuncture-making factors: cycles, duration of exposure, belonging to the market, belongingto the sides of the market mechanism, predictability, controllability, impact orientation, strength of links, origin nature, nature of information,type of dynamics. The other ways of modelling market are also proposed in the theory of microeconomics and the theory ofmarketing, but the proposed variations do not allow simulating the market in sufficient detail for model-based solutions of managerialtasks. The next step was formulation of several requirements, which must correspond to the model and selecting methodology, whichallows creating a model that satisfies the requirements. This methodology is object-oriented design. This specific way of modelling iscurrently used only for programming information systems, however, its set of principles, rules and tools is versatile enough to simulateeconomic processes and phenomena, including market condition. In the conclusion of the article general information is provided on theobject-oriented design: types of used models (object model, consisting of state, behaviour and identity, and interacting with each otherbased on the relationship of client-service type and classes model, reflecting the overall structure and behaviour of a set of homogeneousobjects), principles of modelling (abstraction, encapsulation, hierarchy, modularity), the terms and other.
