Pidkuiko O. Information technology for situational project management based on ontologies

In the dissertation work, an actual scientific and applied task was developwed a new information technology of situational project management based on ontologies, which will contribute to increasing the efficiency of project management. The paper analyzed the necessity of applying situational management in projects, in particular in projects implemented in the field of information technologies. It has been studied that the application of situational analysis in project management, in particular in the field of information technologies, has a number of advantages. This contributes to obtaining more accurate, reliable and complete information for making management decisions in conditions of rapidly changing circumstances. An analysis of the features of the development of models based on ontologies was carried out in order to investigate the possibilities of formal description of knowledge in the form of a space of components. These components are united by the general tasks and goals of the development, which are necessary to solve the problems of situational management. In the conditions of dynamically changing circumstances, the development and implementation of information technology for situational project management based on ontologies is relevant for more effective project management. The work shows that software tools and systems of situational project management are almost non-existent today. This does not provide an opportunity to implement an operational assessment of the project's effectiveness and to make appropriate management decisions that would determine the future strategy. This leads to the need to develop new methods and software and information tools for project management. The author has developed the model of the situation in projects (based on a project in the field of information technologies based on Scrum) in the form of a set of fuzzy values of a fixed set of features, such as performance indicators, situational goals, situational influencing factors. This model provides opportunities for a formal description of the situation in real time and ensures the interconnection and consistency of decisions in accordance with the situation in the conditions of sharply changing circumstances. The work improved the graph-analytical model of situational project management, which provides the possibility of obtaining a cause-and-effect relationship between the current situation, situational goals and decisions. The author built the meta-ontology of situational project management and an ontological model of the situation in projects (on the example of an IT project based on Scrum), which contributes to the development and adoption of an operational management decision for a situation in conditions of a sudden change in circumstances. This model provides opportunities to identify parameters and essential factors that determine the situation, relationships between factors and the degree of their mutual influence. The result of the application of this research is a reduction in the time for making and making a management decision, which ensures an increase in the efficiency of the project due to the avoidance of overspending of resources. The author developed and substantiated the concept of IT situational project management based on ontologies, which, unlike the existing ones, comprehensively characterizes approaches to decision-making in a project situation, is the basis for developing methods and models for creating IT situational project management, taking into account the conditions of a sudden change in circumstances and crisis, and also provides effective project management in various industries, including information technologies. In the work, simulation modeling of situational project management is carried out based on the target scenario, which is expressed by a graph of tasks and reflects the relationship between goals, tasks, transitions and is the basis of the situational decision-making method. The simulation results are presented based on the timing diagram. The author has developed a situational decision-making method based on an efficiency index for various situations in projects, which ensures prompt management decisions in projects, in particular in the field of information technologies implemented on the basis of Scrum. Based on the concept of IT situational project management, the author investigated the formation of information flows of situational project management, which are integrated into the general project management system as an intelligent subsystem of support and decision-making.
