SCIENTIFIC AND ANALYTICAL ASPECTS OF EVALUATION AND SELECTION OF ALTERNATIVES FOR THE IMPLEMENTATION OF A DEVELOPMENT PROJECT AT THE PRE-INVESTMENT STAGE

The topic of evaluation and selection of alternatives for the implementation of development projects at the stage of pre-investment preparation is relevant in the field of construction and investment project management. In conditions when the economic situation is constantly changing, and the requirements for the efficiency and profitability of investments are increasing, it is important to pay attention to the scientific and analytical aspects of modernity, which provide a comprehensive assessment of possible project implementation options. This stage is critical for the further success of the project, not only the financial benefit depends on the correct selection of alternative options, but also compliance with investment goals, social requirements and environmental standards. This paper considers the main methods and approaches used to analyze and evaluate alternatives at the stage of pre-investment preparation. Various factors influencing the selection of the most effective options are taken into account, in particular, economic, technical, legal and environmental. The emphasis is on the fact that the process of selecting an alternative requires not only accurate calculations, but also taking into account subjective factors, such as risk assessment, social aspects and strategic goals of the developer company.Particular attention is paid to the multi-objective optimization method, which allows you to simultaneously fulfill several criteria when making decisions. This makes it possible to carry out a more effective and efficient selection of an alternative that meets the requirements of a specific project. There is also the use of computer models and software to automate the assessment and selection processes, which ensures high accuracy and speed of decision-making The study also covers individual tools that eliminate investment risks, as well as help reduce uncertainty when choosing the most effective options for implementing a development project. The methods considered help not only to make the assessment more justified, but also to reduce the time for making a decision, which is a significant factor in a rapidly changing market environment. aims to form a clear understanding of the importance of a scientific and analytical approach the process of assessing and selecting an alternative for implementing a development project, which ultimately increases the efficiency of investment activities and ensures sustainable development of the construction sector.
