These days big cities are developing faster than ever, influencing the development of the whole country. There are more and more new technologies and innovations that can make people's lives more comfortable and better. However, these technologies and innovations do not appear by themselves. Small and medium-sized business make a great contribution to the development of cities, including in the field of high technologies and innovations. Important aspects of publicprivate partnership, the problems faced by small and medium-sized businesses, as well as modern measures to support small and medium-sized businesses are studied in this article on the example of the city of Moscow. Methods of ResearchThe investigation included the following stages: 1. Review of the main challenges in city governance. 2. The features of state-private partnership eco-system are carried out. 3. Description of possible advances of state-private partnership is given. 4. Conclusions.

Brief analysis of the actual problems of modern quality management and the importance of product quality are highlighted in this article. An overview of the application of information technology in quality management and existing class of information systems that are used for quality control are given. Implementation of algorithm of quality control without the use of complex IS and the assessment of economic effect of the algorithm' implementation are presented. Finally, a pathway for partial quality control automation without the usage of information systems is suggested.

The subject of this research is the process of assessment of an expected effect of projects portfolio with using of real options. The following methods are applied: real options and assessment of the investment project through the cost of the real option, discounting of cash flows, synthesis and mathematical modeling. Novelty of article is the systematization of main types of real options and formalization of computing of the expected effect of realization of portfolio of projects in conditions of risk and uncertainty with use of real options. Results of a research are: main types of real options are systematized and the formula for computing of the expected effect of realization of portfolio of projects in which it is shown that calculation of cost is being built in a portfolio or projects of real options, the additional long-term expenses related to using of these options and decrease thereof the general risk of projects and a portfolio in general allows to increase objectivity of such calculations is offered. Conclusions: in the analysis of real options, the real assets is having as basic, it is often impossible to apply settlement formulas to financial options as they significantly differ. Systematization of main types of real options allows to expand the range of the application of management decisions. Use of more objective formula of calculation of the expected effect of realization of projects portfolio with using of real options allows to increase efficiency of projects insurance in conditions of risks and uncertainty and to use additional opportunities for more effective development of a company.
