Supply chains are starting to be more and more powerful in reaction to transforming company atmosphere as well as innovation. This has produced issues in coping with the flow of resources as well as produced increased probability of interruption. As such this particular analysis evaluates the effect of dynamism on interruption orientations, financial performance, and resilience.

In this paper, we develop a hybrid model that combines scenario analysis technique and cumulant based PPF approach. It can take into account various sources of uncertainty in the power system and their correlations. The proposed approach is performed on IEEE-118 bus test system, indicating good performance in comparison with Monte Carlo approach.

For advanced research reactor designs that have a high core power with downward coolant flow in the core, it is important to analyze a unique postulated pipe break scenario under sub-atmospheric pressures. In order to benchmark the capability of thermal–hydraulic codes such as TRACE to predict flow behavior under these conditions, we must first compare TRACE analyses to reference experimental data for air–water flow near atmospheric pressure and temperature conditions.

The paper presents a novel method for power loss allocation of power systems to demands. This loss allocation technique is based on the contribution of individual demands to the branch power loss of power grids. Results of power flow analysis, precise power system modeling and superposition theorem are deployed in this proposed method.
