ABSTRACT
The article covers issues of supply chain modeling being an important step in the decision-making process. Logistics and supply chain management consider movement and transition of material flow as well as financial, information and other flows associated with it. The characteristics of a flow must be measured considering the dynamics of the flow movement. This determines the importance of simulation modeling in decision-making support system as the approach involves the implementation of modeling system algorithm functioning in a virtual time environment.
The literature analysis, on the one hand, allowed to conclude that the traditional approach to functioning process characteristics determination involving consistent problem solving on the level of supply chain element, is limited or not reflecting the specifics of real processes where the parameters variability in time is possible. On the other hand, there is lack of specific recommendations on building models based on principles of system dynamics as a simulation modeling tool which allows to consider process characteristics variability. This determines the aim of the research a part of which presents supply chain simulation model illustrating the possibilities of the approach. The results of the work can be used both in practice for industrial enterprises and for future research.

ABSTRACT
The specifics of tasks assigned to service companies require concentrating and integrating up-to-date, complete and reliable information formed by the certain rules, and also ensuring prompt provision of this information according to established accessibility order.
It is known that tasks addressed during the after-sales service of complex technical products, including the order and supply of spare parts, can be fulfilled in diverse ways and using wide range of knowledge obtained by service company employees.
Completely identical conditions of conducting after-sales service occur extremely rarely, the volume of information, that needs to be considered to form rational and reasonable decisions, steadily increases, and applied models, methods and technologies do not provide its complete and adequate account. These circumstances objectively require improvement of informational and technological basis of service company operations.
This article contains pertinent problems of informational and analytical operation maintenance of service companies, implementing the after-sales service of complex technical products.
It also proposes methodological approach to selecting the rational option for plan dedicated to improvement of informational and technological basis of these operations based on expert decision support system.
