医疗后送是战时部队卫生工作的中心，世界各国现行的医疗后送体制都基本上构成一个庞大的排队系统。多年来，我国的研究工作者应用排队论的理论和方法，计算机模拟研究了医疗后送的问题。本文介绍一类典型的排队网络及其主要结论，并对研究医疗后送问题提出一些新见解。 Medical evacuation is the centerpiece of wartime troop health work. The current medical evacuation system in all countries in the world basically constitutes a huge queuing system. Over the years, our research workers apply the theory and method of queuing theory to study the problem of medical evacuation by computer simulation. This article introduces a typical class of queuing network and its main conclusions, and puts forward some new ideas on the study of medical evacuation.
