This paper theoretically analyzes the influence of weapon reltability on maintenance and support cost ( M&S cost) in multi-theater deployments. Based on the M&S data of typical on-board equipment, it analyzes in depth the M&S cost in a three-theater deployment scenario with PRICE software and the influence of reliability on M&S cost. The result shows that under the same hardware parameter index, the M&S cost in multi-theater deployments is much higher than that in one-theater deployments and that the cost of equipment Mean Time Between Failures ( MTBF) is also more sensitive than that in one-theater deployments, particularly when the MTBF is relatively low. As a result, the requirement for equipment reliability is higher in multi-theater deployments. 展开更多
