Визначено предметну галузь управління проектами редевелопменту як засобу якісного перетворення міської території. Проаналізовано напрями сучасних досліджень у редевелопменті, що дало змогу виділити їх переваги та недоліки. Визначено необхідність проектування та реалізації інформаційно-аналітичної системи (ІАС) підтримки рішень "Редевелопмент" щодо проекту редевелопменту, зважаючи на багатокритеріальність, багатоваріантність задач редевелопменту, потребу оброблення та зберігання великих масивів кількісної та якісної інформації. Розроблено інфологічну модель ІАС "Редевелопмент", яка містить множину функцій оброблення даних, обчислювальних функцій та функцій забезпечення інтерфейсу з користувачем, що передбачають використання як високорівневої мови програмування C#, так і переваг відомого інструментального засобу MATLAB, необхідні функції якого імплементовано в програму на C#. Представлено схему бази даних, що дозволило здійснювати зберігання та обмін інформацією між користувачами системи, а саме стейкхолдерами проекту: інвестором, замовником, підрядником, управляючою компанією. Базовими функціями аналітичного блоку розробленої системи є такі: автоматизація процедури експертного оцінювання характеристик проекту редевелопменту, прогнозування попиту та пропозиції щодо певного функціонального призначення проекту редевелопменту. Ключові слова: редевелопмент; функціональне призначення; інфологічна модель; об'єкт нерухомості.
The model and method of efficiency estimation for disaster relief process under hydrological emergency of natural character on the basis of fuzzy logic have been offered. It is determined that the implementation of a natural emergency can lead to disruption of the sustainable functioning of the city, region and country as a whole against the background of an constantly increasing human impact on the environment, climate change and other conditions. Natural hydrological emergencies, such as floods, levees, etc., are the most widespread in the world and affect a large number of people, especially the socially and economically disadvantaged part of urban population. An analysis of previous research in this field has been carried out and it is determined that the problem under consideration cannot be fully formulated as a classical deterministic or probabilistic mathematical programming problem. This problem is characterized by significant uncertainty about the problem input variables. Two classes of such uncertainty are identified with the sources of origin - strategic and tactical. The paper presents a formalized procedure for supporting managerial decision-making, which includes the steps of uncertainty consideration and parametric identification of a deterministic optimization model of resource support for the elimination of natural hydrological emergencies. Linguistic variables were introduced to determine the parameters of an emergency, the parameters of the affected area, the characteristics of the technical arsenal of the territorial unit of the State Emergency Service of Ukraine, as well as the life support system. The Mamdani fuzzy inference algorithm was used to evaluate the effectiveness of disaster relief process. The software implementation of this model is executed in the open source information system Scilab, namely in SciFLT subsystem. This model is the basis for further parametric identification and implementation of a deterministic model of resource support for disaster relief process that allows forming flexible management decisions. Keywords: natural emergency, fuzzy logic, flood, resourcing
The article's research subject is the information technology of construction company's material resources management. The work's purpose is to construct and implement tools for modeling construction company's material resources management information technology. The article solves the following tasks: determining the place of information technology of construction company's material resources management in the modern construction company's information ecosystem, defining the main components, and building a functional model of construction company's material resources management information technology, taking into account the shortcomings of existing models, сreation of the multicriteria optimization model of the considered information technology. The following methods are used: system analysis, structural analysis, mathematical modeling of complex systems and processes, multicriteria optimization. The following results were obtained: a structural analysis of the existing information ecosystem at the regional level construction company, the composition of which is agreed on the organizational structure elements of the enterprise and the stages of the construction life cycle; considered the functions of construction company's material resources management which are realized at various stages of a construction project life cycle; constructed the set-theoretical model of material resources management information technology; determined the functional characteristics of the considered information technology, offered the criteria of information technology efficiency according to the ITIL strategy; constructed the conceptual model of information technology of material resources management. Conclusions: for the first time, developed tools for modeling construction company's material resources management information technology, including a theoretical-multiple model of material resources management information technology; Offered the information technology's conceptual scheme which realizes specific information technology's functional characteristics. The built modeling strategy will provide an opportunity for further development and software implementation of the information technology.
