Synergetic is an interdisciplinary area of scientific research, the task of which is to study natural phenomena and processes based on the principles of self-organization of systems (consisting of subsystems) [1]. The methodological approach of synergetic is to talk about common interests and mathematical methods for studying related nonlinear phenomena in different fields of science based on the study of complex phenomena of self-organization [2]. In this paper, based on the methods of synergetic, a new approach to the study of some logistics problems is developed [3].

One of the main tasks of logistics is the organization of transportation. The solution to this problem should be carried out by ensuring the safe and timely delivery of various goods to their destination. Synergetic provides the principles and laws of the coordinated interaction of various parts of a complex system in their oppositions to dissipative destruction, on the interaction leading to the spontaneous occurrence of systemic effects of a spatial and temporary nature.

If we consider the transportation process from the standpoint of synergetic, then the problem arises of its organization by studying all the factors influencing it. Loading and unloading time, travel time, characteristics of the roadmap topology, technical condition of transport and cargo, etc. Synergetic methods allow, from the set of factors influencing the process, to single out the main ones that determine the spontaneous regulation of the transportation process. The combination of factors characterizing the state of the transportation process according to synergetic is called the order parameter. Having determined the other parameter, it is possible to regulate the transportation process so that all the characteristics will act in concert, which ensures a stable dynamic mode of operation of the logistics center, through self-organization of its various functional parts [4–10].

Self-organization — in the most general sense means self-movement, spontaneous structuring of the system and processes.

The idea of self-organization is the disciplinary direction in mode a categorically intern science, seeking the unity of all phenomena and processes.

The main conditions of self-organization are considered 1) a significant remoteness of the system from equilibrium, which is ens1ured by its openness; 2) the openness of the system in our case means a constant inflow and outflow of cargo and information; 3) non-linear interaction between the various functional parts of the system.

The origins of synergetic. At the end of the 20th century, a new science arose. Herman Harken (Germany, Stuttgart) called this science Synergetic.

She studies the laws and principles of the combined action of complex systems. The human body as a complex system is controlled independently according to the laws of synergetic. A complex network of logistics centers can also be considered from the standpoint of synergetic in order to organize a qualitatively new state of their functioning.

If synergy in biology is understood as the joint and homogeneous functioning of organs (for example, muscles) or systems, then in a complex system of a network of logistics centers, these are many characteristics of the interaction between the various functional structures of the centers.

If synergy in medicine is understood as the combined effect of medicinal substances on the body, in which the cumulative effect exceeds the effect exerted by each component individually, then in logistics, synergism is carried out by coordinating various characteristic times of the functioning of transportation processes.

Synergetic logistics is anew area of research of the land transportation system in our republic. It is necessary to create training programs in this direction, aimed at training new personnel professionally knowledgeable in engineering synergetic methods and successfully using them in the practice of logistics centers. Today, precisely, the synergetic methodology allows us to create a conceptual basis for logistics and make a breakthrough in this area.

Human health is determined by the concerted action of all parts of a person. To study, for example, physiological processes according to the method of synergetic modelling, it is necessary to find the so-called order parameter of the system under study. Heart rhythm is a parameter of the order of the cardiovascular system. Therefore, the main task of medical engineers is to develop new medical technologies for the analysis of complex dynamic parts of the whole organism. In the first approximation in synergetic logistics, the following characteristics of the transportation process should be taken into account.

The share of the safely delivered cargo to the destination is accepted as an order parameter.

The control parameter includes the time of cargo delivery as a measure of the transport system of the logistics center.

The Figure shows a general topological model of the transportation process.

Figure. General topological model.

In this figure, the transport process is described by a parabolic curve. The coordinates of the image point on it characterize the state of transportation. When the control parameter changes, this point shifts along a parabolic trajectory.

As can be seen from this figure, as the value of the control parameter increases, the point shifts to the right, which is accompanied by a decrease in the value of the order parameter. Upon reaching the zero value of the order parameter, the system is destroyed i. e. in our case, the center of Logistics ceases to function.

Conclusion

Application of synergetic methods to solving some problems of the transportation process allows us to find the main characteristics of the stable functioning of the logistics centers and the transport system. It is shown that the share of successfully cargo delivery critically depends on the ratio of the characteristic timed of the functioning of the center’s transport system.
