The system of integral indexes for estimation of economic efficiency of warm isolations of dwelling and civil buildings is resulted in the article. For the management by energysavings measures during realization of investment projects in the conditions of financial limitations effectively to apply economic-mathematical methods. Application of method of the dynamic programming at the choice of effective measures on the heatcover of barriering constructions of buildings allows to get the mixed optimum strategy of the use of the limited investments.

The Republic

The period of transition of the national economies from the socialist system to the market economy system is marked by a whole series of economic and social events, where investments represent a driving force for the country's economic development. The aim of the research is to provide scientific assistance on the widespread use of modern methods, recognized in developed industrialized countries, to elaborate and/or evaluate investment projects on the basis of which the indigenous agricultural sector will be able to survive in harsh conditions of often unfair competition from the part of Western agricultural producers. The main research methods are qualitative and quantitative analysis of economic events, comparative and statistical comparisons, dynamics and trend studies, economic and mathematical methods to justify the economic efficiency of investments, etc. As the results, obtained from the out carried researches, can be called the algorithms of calculation and performance indicators for assessing the level of economic efficiency of agrarian business investments, which for year along are successfully used in the Western European countries, but practically totally ignored within the national economy of the Republic of Moldova.

The article outlines the main features of the use of the theory of indefinite bundles in the evaluation of the cost-effectiveness of investment projects.He analysis of methods for quantifying the effectiveness of the IP under uncertainty suggests that the existing methods either eliminate the uncertainty from the IP model, which is inappropriate, since uncertainty is an integral characteristic of any forecast, or are unable to formally describe, and take into account all possible varieties of types of uncertainty.Methods based on the theory of fuzzy sets refer to the methods of evaluation and decision-making under conditions of uncertainty. Their use implies the formalization of the initial parameters and performance targets of the IP in the form of a vector of interval values (fuzzy interval), the hit in each interval of which is characterized by a certain degree of uncertainty.Also, the fuzzy-interval approach has advantages in solving the problems of forming an optimal portfolio of investment projects. To solve the problem of forming an optimal IP portfolio, a large number of models for the formation of an optimal IP portfolio have been developed, differing from each other in the form of objective functions, variable properties, used by mathematical methods, and uncertainty.

International innovation and investment activity occupy a special place in the system of modern international business. The authors propose an economic and mathematical model for assessing the sensitivity of international innovation and investment projects by the criterion of net present value. It is advised to use the obtained sensitivity indicator as an additional one in assessing the economic efficiency of international innovation and investment projects of an enterprise. The proposed model makes it possible to determine the effect of several internal parameters simultaneously on the net present value of the project.

The introduction provides a brief review of the literature on methods for assessing the effectiveness of investment projects, based on which the choice of optimal sources of financing is made. In the main part of the work, various scenarios for the implementation of an investment project are disclosed: sources of financing that are alternative to the baseline scenario are attracted. In the final part of the work, the considered scenarios are assessed and conclusions are drawn.For each enterprise, improving the financial and economic efficiency of its activities is one of the priority tasks. These tasks include the need to increase the return on capital, the choice of funding sources that have a positive effect on economic efficiency. This paper examines the ways of choosing the optimal, from the point of view of the impact on economic efficiency, instruments for financing an investment project. A practical case of project financing with an assessment of the effectiveness of the implementation of an investment project is considered. To analyze the alternatives, a financial business model was developed, which allows you to quickly make changes, update performance indicators and make decisions about the required capital structure. It is concluded that the optimal capital structure with the highest NPV indicator and that when assessing the efficiency parameters, it is necessary to make an adjustment for the possible presence in the company's capital structure of funding sources that distort the comparability of the project in relation to projects without such sources (for example, budget grants).

 The article systematized factors of investment attractiveness and investment climate in Ukraine. The expediency of supplementinganexistinglist of components of investment climate is substantiated by two additional factors. Themechanismo factionoftheproposedfactorsthatreflectthenegative effectin the developmen to freformsand innovations, aswellas the economic efficiency of construction projects on the financial result, expected from investigations, isrevealed. The trends in the developmen to finvestment activityinUkrainein 2015 - 2020, the existence of reserves for increasing the economic efficiency of investments and the need for their calculation witht hehelpof a special methodological approac hare analyzed. The methodical approach to the evaluation of investment efficiency of constructionis developed, which is based on the magnitude of the multiplier of capital investment in construction inthelong-termperiodandrefinedtheboundariesoftheretrospectivehorizon, which are necessary to determine such a multiplier. The rapid importance of aninvestment multiplier of construction isestablis hedand a methodological approach to qualitative interpretation of this indicator issubstantiated. The basis of a methodological approach is the results of a cluster analysis of aninvestment multiplier in the contex to fvarioustypesofconstructionandregions, the methodof K-medium, aswellaspostulatesofthetheoryoffuzzysets. Within the framework of the developed methodological approach, the "investment attractiveness of construction" characteristicsis presentedin the form of a fuzz yterm-shear, which combines three terms: "Lowefficiency", "averageefficiency", "highlevelofefficiency". Inaccordance with descriptiv estatistics of thereceived clusters, the parameters and type of functions of affiliation, the boundaries of clusters that directly affecttheuse of correctivea mendments to the value of the economic effectof capitalinvestment to the level of the contractor-executor of construction work are substantiated.
