Performance evaluation of man-portable devices based on the cloud center of gravity

Abstract In order to accurately assess the performance of man-portable devices, a method evaluating devices based on cloud center gravity evaluation is proposed. Firstly, index system was constructed by analyzing factors affecting devices. Then, using judgment method, device model established and weighted deviation applied determine results. Finally, examples, we verify feasibility effectiveness method. The research work provides ideas references for scientific assessment equipment, further theoretical basis modification development this type equipment.
