“…for the duration and cost of project implementation. In comparison with the method of successive concessions [24,25], our method makes it possible to accept concessions not only to the components of the «ideal point» but also to change the initial data, in particular in the set of workers. The proposed solutions for this stage enable DM to act in accordance with different management strategies, which makes the proposed approach more universal and corresponds to the hypothesis of improving the quality of planning by establishing communication between responsible persons [27].…”

“…For the case when the Pareto set has a sufficiently large power, it is proposed to apply dialog methods of multicriteria optimization, including the method of successive concessions [24,25]. The use of such methods makes it possible to take into account the limitations provided by DM in a dialog mode, which significantly speeds up the decision-making process.…”

This paper reports an analysis of aspects of the project planning stage. The object of research is the decision-making processes that take place at this stage. This work considers the problem of building a hierarchy of tasks, their distribution among performers, taking into account restrictions on financial costs and duration of project implementation. Verbal and mathematical models of the task of constructing a hierarchy of tasks and other tasks that take place at the stage of project planning were constructed. Such indicators of the project implementation process efficiency were introduced as the time, cost, and cost-time efficiency. In order to be able to apply these criteria, the tasks of estimating the minimum value of the duration of the project and its minimum required cost were considered. Appropriate methods have been developed to solve them. The developed iterative method for assessing the minimum duration of project implementation is based on taking into account the possibility of simultaneous execution of various tasks. The method of estimating the minimum cost of the project is to build and solve the problem of Boolean programming. The values obtained as a result of solving these problems form an «ideal point», approaching which is enabled by the developed iterative method of constructing a hierarchy of tasks based on the method of sequential concessions. This method makes it possible to devise options for management decisions to obtain valid solutions to the problem. According to them, the decision maker can introduce a concession on the value of one or both components of the «ideal point» or change the input data to the task. The models and methods built can be used when planning projects in education, science, production, etc.
