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 task of diagnostics of supply chain processes with the purpose to determine reserves and prospects of efficiency increase is the most time-consuming stage of strategic planning requiring accumulation and systematization of large amount of diverse information. Alongside with this, there are not many complex methods that could allow to implement the strategic planning cycle providing at the same time objective conclusions. One of these methods is the diagnostics of supply chain processes using supply chain operations reference model (SCOR model). The article provides analysis of publications devoted to problems when using SCOR; shows the main problems of the method interpretation and its application peculiarities. Also, the article suggests a procedure of supply chain processes diagnostics with SCOR model; the stages of this procedure are supported with an example. The article reveals that consistent implementation of the described stages allows to significantly simplify the procedure of supply chains strategic analysis providing at the same time consistency and reasonability of the decisions taken.
