The fast development of computer technique is promoting the revolution in military affairs. Modeling and simulation technique based on computer technique has been applied extensively in the field of national defence. Effective applications have been achieved through modeling and simulation in the field of integrated supportability engineering. The paper investigates the current development of modeling and simulation and describes its research status in the integrated supportability engineering. Advanced modeling technique and simulation technique are introduced and foreign models in the field of integrated supportability engineering are also roughly analyzed. In the end the paper presents the demerits of our modeling and simulation in the integrated supportability engineering and puts forward some advice as well.
