考虑了带干扰的Erlang(2)风险模型罚金函数的期望,利用建立的积分-微分方程,得出了期望的明确表达式.
The moments of the surplus before ruin and the deficit at ruin caused by a claim when the risk model is the Erlang(2) risk process perturbed by diffusion is considered. The explicit expression for the moments is obtained by using integro-differential equations.
