In this thesis statics and dynamics of supply chain network with integrated environmental decision-making in the form of social responsibility activities is observed. The model consists of three tiers of decision-makers, respectively: manufacturers, retailers and consumers associated with the demand markets. For each tier, or decision maker, it is observed the multicriteria problem which includes problems of profit maximization, emissions (waste) minimization and risks minimization which are associated with the corresponding weights. Types of transactions between stakeholders in supply chain network are B2B (business-to-business) and B2C (business-to-consumer). The levels of social responsibility activities affected the risk, emission and transaction costs (reducing them), but also generated costs. Firstly, the network in equilibrium is modeled. Product transactions and levels of social responsibility activities between tiers in the network (decision makers) coincide. Then, the variational inequality formulation for the governing equilibrium conditions of certain decision makers, and the whole network in general was established. Then, (disequilibrium) dynamics associated with the continuous-time adjustment process was suggested. Projected dynamical system corresponding to the model was constructed. It is proved that the set of stationary points of the projected dynamical system coincides with the set of solutions of the variational inequality problem. There are also provided conditions under which the dynamic trajectories of the product flows, levels of social responsibility activities and prices are well-defined. Theoretical results given for the static (equilibrium) and dynamic (disequilibrium) were used to calculate numerical examples. Numerical examples show only a small number of options that can be modeled, but suggest the importance of including social responsibility in the supply chain network.
