This paper investigates problems related to supply chain risk identification and simulation‐ based risk evaluation. Accordingly, the paper is divided into two logical parts. The first part represents earlier researches about risk recognition within the sphere of supply chains. The distinction between terms “uncertainty” and “risk” is discussed. Based on the predefined supply chain functions, additional risks connected with supply chain reliability are recognized. Then, a conception of simulation‐based risk evaluation approach is discussed. Within the second part of the paper, a numerical example is provided, within which a simplified supply chain system is defined and corresponding risk evaluation is performed. Santrauka Šiame straipsnyje nagrinėjamos problemos, susijusios su tiekimo grandinės rizikos identifikavimu ir modeliavimu pagrįstu rizikos įvertinimu. Straipsnis suskaidytas į dvi logines dalis. Pirmojoje dalyje aprašomi ankstesni tiekimo grandinėse slypinčių rizikų tyrimai. Aptariami terminų neapibrėžtumas ir rizika skirtumai. Remiantis pasirinktomis tiekimo grandinės funkcijomis, nustatytos naujos rizikos, kurios veikia tiekimo grandinės patikimumą. Toliau aptariama modeliavimu pagrįsta rizikos įvertinimo koncepcija. Antroje straipsnio dalyje pateiktas skaitmeninis pavyzdys, kuriame sudaroma supaprastinta tiekimo grandinės sistema ir įvertinama su ja susijusi rizika.

By establishing a two-level symbiotic supply chain system consisting of one supplier and one manufacturer, we use Stackelberg method to analyze the optimal price and revenue model of supplier and manufacturer in the symbiotic supply chain under two power structures in which the supplier and manufacturer are dominant respectively, and analyze the influence of the degree of symbiosis and power structure on the model. Through comparative analysis, we find that: There is a relationship between the income level and the degree of symbiosis in the symbiotic supply chain. The change of power structure will affect the relative benefits of suppliers and manufacturers in the symbiotic supply chain. The manufacturer’s expected unit product revenue will affect the supply chain revenue when the manufacturer is dominant. Finally, the sensitivity analysis of relevant parameters is carried out through an example analysis, and the validity of the conclusion is verified. This paper has a guiding significance for the behavior of enterprises in the cogeneration supply chain.
