In the context of globalisation, the development of strategic planning becomes possible mainly due to effective asset management, including by concentrating resources on core activities, solving priority key tasks while minimising costs for "supporting" functions. In this regard, increasing the effectiveness of strategic planning in public administration is possible on the way of forming an economically profitable system of interactions, an important place among which is occupied by outsourcing relations. The study aims to develop practical recommendations on the use of outsourcing services to improve strategic planning in public administration. The main results of the work are that it defines the theoretical foundations for strengthening administrative and managerial processes in the public administration system, analyses various approaches to improving the public administration system, and proposes an algorithm for making a decision on the use of outsourcing in the public administration system and recommendations for assessing the practicality of transferring the functions of state bodies to outsourcing. The need to optimise the management strategy and to plan as the main direction of increasing the efficiency of the functioning of the public administration system predetermines the high degree of relevance of outsourcing of business processes and necessitates further comprehensive scientific substantiation of methods for its implementation.

Methodical approaches to the analysis of the efficiency of fixed assets use in building organizations on the basis of economic-mathematical models are offered. The sequence of calculations of analytical indicators of the main means of resources, which allows to obtain a reliable assessment of their effectiveness, is developed. The composition of factors and reserves for increasing the efficiency of the fixed assets use is revealed and specified, that will enable to raise the return on assets and profitability of building organizations fixed assets.

Introduction. When solving optimal tasks at the stage of technical and economic planning, it is necessary to establish an optimality criterion, which is mathematically written as an objective function. Minimization of the duration of the project works during its implementation within the time limit set by the investor is such a criterion in the formulation of our task. By limitations of the model, we understand such conditions, which are expressed in the limitation of resources both quantitatively and qualitatively: hence the problem of their saving, the best distribution, and effective use arises.Goal consists in the theoretical and methodological substantiation of the concept of managing the effectiveness of investment planning with the use of economic and mathematical modelingResearch methods. In the research process, general scientific and special methods of cognition were used: analysis and synthesis, theoretical generalization and formal logic, system approach, classification, statistical analysis, functional-value analysis, generalization, observation, mathematical statistics, simulation and network modeling, specification, technical and economic calculationsResults. It was found that with the help of the proposed technology «Flow» it is possible to determine: the calendar schedule of works for the optimal version of the project implementation; the calendar dates of the start and end of critical works, on which the duration of the entire project depends; actual project implementation costs. The value of the objective function shows what additional costs are necessary for the implementation of the investment project in a given period. It has been proven that the «Flow» technology allows you to determine the value of the model and, in our opinion, demonstrates the improvement of the existing solution to the tasks of project implementation within the given time and ensures the compatibility and unity of information support, and therefore allows you to receive more reliable data. The main advantages of the proposed method were evaluated: availability of raw data; a calculation algorithm that is understandable to any project participant; clarity of results; connection in a single model of the economic interests of the main participants of the project.Perspectives. Further research should be aimed at carrying out a continuous process of qualitative and quantitative assessment of the effectiveness of the project management information system and the need to create a special organizational unit - a strategic committee, which will allow the creation of mechanisms for effective management of investment projects of the territorial community, to achieve its strategic goals, and will also contribute to the implementation of strategies due to the consistent actions of the community investment development management staff.

Accordingly, innovative solutions aimed at improving sales should receive a response to gross sales revenue. The management mathematical dynamic models proposed in the work scientifically substantiate the decisions made and allow predicting the influence of the system of innovative development factors and physiological working conditions of employees on the financial condition of the enterprise.

building organizations on the basis of economic-mathematical models are offered. The phenomena, related to supply and storage of materials, their production use and impact of material supply on the financial structure of capital, occurred in the enterprise, are determined by means of the analysis of the production functions of dependence of return of fixed assets on material resources, and it was also investigated how such phenomena affect the return on fixed assets. On this basis, the recommendations how to improve the management of materials supply in order to provide the fullest use of fixed assets are developed. Based on the study of the value of the coefficients of linear models of dependence of the financial indicators of the enterprise activity on the value of material stock, the price of a unit of stock, the types of stock, on which the profitability of the enterprise significantly depends are determined, and it is also defined what economic, financial, organizational and technological regularities are covered by these dependencies. An economic interpretation of such dependencies is given and the recommendations for improving stock management and the material supply structure are developed. The qualitative analysis of dependence of the financial indicators of the enterprise activity on the value of the stock and its cost is carried out. The recommendations for improving the management of the size and the price structure of the most important material stock are developed
