: The purpose of the study is to develop a simulation system-dynamic model for evaluating the performance of a trading company based on the analysis of dynamics of four balanced parameters: finances, customer relationships, internal business processes, as well as staff qualification and training. Implemented at the experimental level, the simulation model allows determining the balanced contribution of these parameters with the aim to obtain the best option of a business-oriented strategy. This provides the efficiency of invested funds with the account of the analysis of planned changes in the enterprise. The system dynamics method is used as the most acceptable tool to balance all subsystems of corporate governance. [ABSTRACT FROM AUTHOR]

The paper presents an experimental simulation system-dynamic model for analyzing the efficiency of processes of discrete-event systems. The simulation results for an abstract production queuing system with failures and two service devices confirm the possibility of applying this approach to the modeling of discrete-event processes by means of system dynamics method. This approach can be used in the analysis of production efficiency in terms of forecasting of direct production costs, taking into account the data on equipment downtime, and in the studying the risk of irregular decreases in process performance.

The article presents the results of applying the system dynamics method as a tool for optimizing the interaction processes between participants in digital projects. The expediency of applying the system dynamics method for modeling key performance indicators of the target architecture in the digital economy, which allow tracking the success of an IT company in dynamics, is substantiated. A system-dynamic model for optimizing the processes of interaction between the participants of informatization projects in the IT company is developed. [ABSTRACT FROM AUTHOR]

The paper is devoted to analysis of the structure of approximation schemes for value functions in optimal control problems with the infinite time horizon. The problem peculiarity is a quality functional with an unbounded integrand, which is discounted by an exponential index. The main result is reduction of the optimal control problem to an equivalent problem with the value function that has the compact definition domain and the compact value range. This goal is reached by a series of nonlinear changes of variables and the transformations of the system dynamics and the Hamilton-Jacobi equations. The proposed method is resulted, first, in obtaining the strongly invariant calculation domains of approximation schemes and, second, in compactification of ranges for the value functions. The first property provides the opportunity to implement approximation schemes in the form of numerical finite difference schemes for the value functions in compact definition domains. The second property guarantees convergence of approximation schemes to the value functions. [ABSTRACT FROM AUTHOR]

The application of CAD/CAM technologies was a technical breakthrough in the use of automated systems for production in the most efficient way, with high quality and minimal costs. This increases the requirements for CAD/CAM research and development, application in product design, and more detailed development of process tools. The paper presents the analysis of CAD/CAM systems market dynamics for last years and the most promising applications spheres of such systems are identified. [ABSTRACT FROM AUTHOR]
