This study developed a descriptive 3D city information model (CIM) using only infrastructural building modeling tools to create maps, and analyzed the model according to needs identified in interviews with public-sector actors and a bibliometric analysis. The interviews assessed the challenges of implementing CIM in the Brazilian city of Curitiba, while the literature study determined that current academic production reflects the current reality, calling attention to relevant issues. The experimental software solution successfully created 3D informational modeling of cities for passive use as well as maps to support decision making, although it did not offer advanced parametric tools for urban analysis. Still, this model provides a flexible approach to overcoming the challenges reported by interviewees, which included financial limitations and organizational culture.

In the context of the general trend to accelerate change, the actual goal of scientific research in the field of construction is to analyze and design the stages of the life cycle of a construction object. The object of the study becomes the information model of the life cycle of the building. It is studied and modeled based on the concept of real estate development and using the methods of project analysis of the construction project. The widest possibilities for obtaining and analyzing data on the state of a construction object, as well as the possibilities of systematizing information flows and information modeling of different periods of its life cycle, are realized in the approach of BIM modeling of buildings and structures. With the help of BIM-modeling tools, mandatory stages and possible phases of the life cycle of a building object can be represented as hierarchically and sequentially related information flows, in which the attributes of each stage of the life cycle are formed under the influence of the preceding stages and of special factors for the considered stage. As a result, the project documentation should reflect the decisions aimed at providing the necessary conditions and opportunities for subsequent periods of the life cycle of the construction object, as well as the most adapted for the predicted changes and transformations for all future stages and phases. The analysis of characteristics and the developed structure of simple and complex construction works allows determining for each stage and phase of the life cycle of a construction object: interconnection of information flows, composition and content of the information model of the building required for the work of specialists.

Enterprise models are created for communicating and documenting the current state of the enterprise. However, these models can also be used for supporting analysis processes and are fundamental assets in project management. But, analysis is a process made by humans, and due to enterprise models that are complex and have a large amount of elements, analysis is usually a tough process. Then modeling tools might provide support for analysis. It is possible to offer this support through the use of automated analysis methods, which are algorithms for providing specific calculations based on the elements included in the model. The results of said automated analysis methods support decision-making processes. It is also possible to execute a sequence of analysis methods by the configuration of analysis chains. This chapter presents a proposal and strategy for analyzing enterprise models by the execution of automated analysis methods and automated analysis chains. This strategy is presented using enterprise models that conform to ArchiMate as modeling language.

Summary Objectives: Several standards applied to the healthcare domain support semantic inter-operability. These standards are far from being completely adopted in health information system development, however. The objective of this paper is to provide a method and suggest the necessary tooling for reusing standard health information models, by that way supporting the development of semantically interoperable systems and components. Methods: The approach is based on the definition of UML Profiles. UML profiling is a formal modeling mechanism to specialize reference meta-models in such a way that it is possible to adapt those meta-models to specific platforms or domains. A health information model can be considered as such a meta-model. Results: The first step of the introduced method identifies the standard health information models and tasks in the software development process in which healthcare information models can be reused. Then, the selected information model is formalized as a UML Profile. That Profile is finally applied to system models, annotating them with the semantics of the information model. The approach is supported on Eclipse-based UML modeling tools. The method is integrated into a comprehensive framework for health information systems development, and the feasibility of the approach is demonstrated in the analysis, design, and implementation of a public health surveillance system, reusing HL7 RIM and DIMs specifications. Conclusions: The paper describes a method and the necessary tooling for reusing standard healthcare information models. UML offers several advantages such as tooling support, graphical notation, exchangeability, extensibility, semi-automatic code generation, etc. The approach presented is also applicable for harmonizing different standard specifications.

A semantic information model to improve reuse and communication of engineering design knowledge is presented in this paper. We consider design to be a process involving a sequence of decisions informed by the current state of information. As such, the information model developed is structured to reflect the conceptualizations of engineering design decisions with a particular emphasis on semantically capturing design rationale. Through the approach presented, knowledge reuse is achieved by communicating design rationale. A case study is presented to illustrate two key features of the approach: (1) seamless integration of separate modular domain ontologies and instance knowledge related to engineering design that are needed to support decision making and (2) the explicit documentation of design rationale through design decisions.

Abstract. Urban planning is a very complex task, especially considering the many challenges it faces, including an increasing need for housing in response to demographic growth and a need to limit abusive land artificialisation. As part of an interdisciplinary action-research project focused on experimenting with various uses of an existing City Information Model (CIM) for urban design, we are developing a new indicator to characterize urban intensity and a method to quantify it through the City Information Model (CIM) of a French eco-district. Our project is ongoing, and, in this paper, we present intermediate results on the potential of this CIM to support the automated quantification of our urban intensity indicator. We also describe the solutions currently implemented so that our experimental CIM can provide the necessary information for a more complete and automated urban intensity analysis. Finally, we shed light on key issues regarding the use of CIM, specifically CIM made up of various BIM models (of buildings lots and public spaces) for urban analysis at the district scale during the design phase. These issues include the need to generalize BIM entities and to manage property sets and nomenclatures to allow automation of analyses at the district scale, as long as there is no BIM+ data model allowing for urban analysis.

Ambiguous situations affect the progress of the project in any area. They are unpredictable in nature and require consideration of fairly new and complex factors that to varying degrees determine the effectiveness of the project. The article considers the use of situational analysis in building an information model of project management in the field of information technologies. Knowledge and the ability to aply the situational approach in the conditions of flexible methodology Scrum will provide opportunities to the project manager to change a situation radically in the project and to achieve the motivated performance of each task. The authors offer a formalized presentation of the procedure for selecting the optimal solution in project management in the implementation of a flexible Scrum methodology. The paper investigates the causal relationship between tasks, goals, situations in the project. Management decisions in the project are implemented on the basis of a study of how the task ensures the achievement of the goal. This takes into account all the features of the flexible Scrum methodology. The procedure of making the optimal decision on the basis of construction of the diagram of situations is offered. A set of solutions that help to overcome the crisis situation is established, and possible alternatives are explored. The use of situational analysis in the implementation of the flexible Scrum methodology provides a comprehensive approach to project management by synthesizing methods of expert assessments and intelligent management methods that will support decision-making in crisis situations of possible conflicts with existing constraints on financial and time resources. The result of the application of the developed information model is to increase the efficiency of the project by reducing the loss of time in the project and overspending of financial resources.
