Invariant Sets of Impulsive Differential Equations with Particularities in ω-Limit Set

Sufficient conditions for the existence and asymptotic stability of the invariant sets of an impulsive system of differential equations defined in the direct product of a torus and an Euclidean space are obtained.

A Synergistic Effect in Logistics Network

The objective of this study is to investigate supply chain performance with a focus on transport logistics. The expected effects and capacity of potential changes in supply chain performance should be taken into account while developing a management decision on logistics network functioning. The paper proposes an analysis and a quantitative estimation of positive/negative effects and supply chain performance caused by a change of average speed and loading/unloading time in logistics network of trucks with full load. It is shown that a combination of these two factors leads to the overall synergistic effect with increased output.
