Enhanced Heavy Equipment Transport System (EHETS) Analysis of Alternatives (AoA) Sensitivity Analysis

摘要

The Army introduced the M1 Abrams Main Battle Tank (MBT) in 1979 along with the Heavy Equipment Transport System (HETS) to act as its primary transport. In response to new technologies and emerging threats on the battlefield, the M1 Abrams tank underwent numerous upgrades and is projected to exceed the carrying capacity of the current HETS. Therefore, The Research and Analysis Center (TRAC) is conducting an Analysis of Alternatives (AoA) for a new transporter, the Enhanced Heavy Equipment Transport System (EHETS). As part of this effort, TRAC performed sensitivity analysis to determine the effect of operational and maintenance variables on operational availability of the EHETS. Operational availability is a critical metric for the EHETS, and it is important to understand the impact of system design and external factors on availability. This research makes use of design of experiments (DOE) to quantify the effects of primary operational and maintenance variables which affect the operational availability of the EHETS. These variables include reliability, recovery time, parts distribution and time required to repair within an operational scenario. The research used Logistics Battle Command (LBC) simulation models dynamic maintenance feature to conduct the operational availability sensitivity analysis.
