Title: Project as a System and its Management
Abstract: The contribution aims to describe project as a system, to define project control goal and strategy, control variables and their relationships. Three common control variables represented by the project triangle, are extended by two other important variables - project risk and quality. The control system consists of two components: social one - project manager and project team - and technical one - project dynamic simulation model as a decision making support of project manager in project milestones. In the project planning phase, the project baseline with planned controlled variables is created. In milestones after project launch, the actual values of these variables are measured. If the actual values deviate from planned ones, corrective actions are proposed and new baseline for the following control interval is created. Project plan takes into account the actual project progress and optimum corrective actions are determined by simulation, respecting control strategy and availability of resources. The contribution presents list of references to articles dealing with project as a system and its simulation. In most cases, they refer to the project control using the Earned Value Management method and its derivatives. Using of the dynamic simulation model for project monitoring and control, suggested in this contribution, presents a novel approach. The proposed model can serve as departure point to future research of authors and for development of appropriate and applicable tool.

Title: Bitcoin System
Abstract: Cryptocurrency systems are purely digital and decentralized systems that use cryptographic principles to confirm transactions. Bitcoin is the first and also the most widespread cryptocurrency. The aim of this article is to introduce Bitcoin system using a language understandable also to readers without computer science education. This article captures the Bitcoin system from three perspectives: internal structure, network and users. Emphasis is placed on brief and clear definitions (system components) and their mutual relationships.  A new system view of the stated terms constitutes author’s own contribution.

Title: Methods for Project Tracking in Creative Environment
Abstract: The objective of this paper is to design new alternative methods for project tracking in creative industry environment. One of the research method is system dynamics modelling. A dynamics model accepts problems which were identified based on qualitative research and assessed using the system thinking method. A system dynamics model contains a project reference mode which correctly and provably expresses the planned and actual project development in terms of scope and budget. Reference mode of the project was discovered on the basis of Earned Value Management method modification. System dynamics modelling suitability is demonstrated on a case study of a creative project called “Water for Everyone”. If the project is behind schedule, the simulation explains why it happened and forecasts further project development. Managers can use the modelling process to evaluate the impact of their decisions on the next stages of the project life cycle and adopt new management practices using scenarios. The published research is valuable for key stakeholders as it is practically focused on ascertaining essential information about the project progress.

Title: Systems Approach to Scientific Investigation in Informatics
Abstract: The level of informatics development is causally linked to the level of scientific development in the area. Successful scientific work is based not only on the investigative style of thinking, but it also means to think in context and to see the whole setting of the solved research problem - to be able to apply system approaches. System approaches include System Dynamics; a community practicing system dynamics has become the strongest school of system approach with many members of the academic environment as well as from real life practice. The aim of the article is to show the possibilities of system dynamics models as appropriate tools to support system approach to scientific research in informatics. The multidisciplinary and quantitative concepts that are typical of System Dynamics are, according to the authors, suitable for systemic solution of the complex problems of current IT practice. Conducted research and examining the principles of system dynamics including the stages of creation of its models confirm these author's arguments.

Title: Transcendental Dimension of the Reality and Systems
Abstract: Transcend (origin Latin transcendere = climb) means go beyond or exceed the limits of something abstract, esp. be beyond the range or grasp of human experience, reason, belief etc. Also be above and independence of, esp. of God exist apart from the limitations of the material universe. Surpass, excel or exceed in a special quality or attribute. Adjective transcendent denotes what is surpassing or excelling others of this kind, supreme beyond the range of human experience, reason, belief etc. In scholastic philosophy higher than included in any of ten Aristotle´s categories, in Kantian philosophy something not realizable in experience, in mathematics a transcendental expression is e.g. a non-algebraic function. Adjective transcendental chiefly in Kantian philosophy means presupposed in and necessary to experience, in modern sense superrational, superhuman, supernatural, metaphysical, vague, obscure; esp. in Emersonian thought regarding the divine as the guiding principle in humankind. Transcendentalism is the transcendental philosophy or thought, a system of this, esp. an exalted or visional language, a transcendent quality of character. These features are studied in context of the systems engineering.

Title: System Approach in RIPRAN Method
Abstract: The article describes reasons, principles for design, structure and using of RIPRAN method (Risk Project Analysis) for risk project analysis. The RIPRAN method is used to identify, quantify risks, and design proposals that reduce risk in the project to increase the likelihood of successful completion of the project. The method uses a system and process approach to risk analysis and respects international ISO standards that recommend how to perform a high quality risk analysis of the project. The method has been incorporated into the national standard of the Czech Republic among the recommended knowledge for certified project managers. The third version of the method is available. The method is included in teaching at many universities in the Czech Republic, trained by a number of training firms and used by firms to analyse the risks of corporate projects or by various risk analysis institutions for projects funded by the EU structural funds. The aim of the article is to inform about the RIPRAN method. At the same time, the paper points out that the method describes the procedure for risk analysis of the project and presents the benefits of RIPRAN application. The description of a system approach application when designing the RIPRAN method serves as an example of a system approach to risk engineering.
