By applying the fixed point theorem, we derive some new criteria for the existence of multiple positive periodic solutions for two kinds of   -dimension periodic impulsive functional differential equations with multiple delays and two parameters: ), a.e., , , , , , and ), a.e., , , , , , As an application, we study some special cases of the previous systems, which have been studied extensively in the literature.
