Resumen
The subject of the given work is the development of mechanism of market interaction between the business activity subjects at the gas market. The study is relevant due to the fact that although many companies have a corresponding credit policy, the existing mechanisms of managing the enterprises? receivables do not have sufficient impact on consumers. The aim of the study is to develop a mechanism for managing receivables of gas transport companies, taking into account the effectiveness of debt recovery measures. The task of the work is to determine the criterial characteristics of receivables of gas transport companies and to assess the possibilities for debt collection. During the study, in the work have been used methods and basic provisions of financial management to assess the state of debt, fuzzy inference to determine the feasibility of using methods of influencing the debtor to recover the debt in favor of the gas transmission enterprise. The outcomes: were analyzed and classified the indexes, which define the base of consumers of the gas transport enterprise PJS "Kharkiv gas" and all of its structure departments. The list of verbal criteria of the consumers analysis includes: the frequency of purchases; total size of purchases; the balance of the debt; the expected maturity of the debt; maintenance of a debt; the profitability of debt collection in court. Based on the survey of experts, two linguistic variables were used to characterize the effectiveness of work with consumers-debtors in two directions ? "Planned costs of debt support" and "Expected revenues from the debtor". A base of rules was formed at the basis of the data and the expert survey, in which were calculated distinct indicators that can be used for future interaction with the consumer. The variables, which characterize all of the consumers-debtors, do not have a direct connection. Therefore, an additional variable was introduced to compose the aforementioned indexes ? the effectiveness of debt collection depending on the used method of influence on the debtor. The conclusion: In the given work is proposed an algorithm for determining the way the applied methods of influence on the debtor can lead to an increase in the cash flow of the gas transportation enterprise. In the future, it is possible to improve the calculations by studying and assessing the impact of decisions on the achievement of planned indexes.
