New Approaches in Measurements, Methodologies in System Analysis and Modeling of Complex Systems

The modern information society is developing rapidly and science is progressing every day, new discoveries are being made in all spheres of life, humanity is resorting to the use of advanced technologies. The primary task now is to systematize the acquired knowledge into certain «systems» – a set of interconnected elements. It should be noted that the measurement methodology is one of the most difficult problems in economic research. Systems are rapidly becoming more complex, specialists are forced to work with tasks whose conditions of external factors are unknown, and new approaches to measuring and solving these problems are emerging in order to solve them. Modern tasks require solutions even in conditions of uncertainty, analysts need high accuracy of execution and care to avoid mistakes, and the results must be reliable. Currently, measurement is a key element of system analysis and its methodology, thanks to which it becomes possible to obtain information about each element of the system.
