Supportability Analysis (SA)


HEI�s logisticians apply an iterative analytical process by which the logistics support necessary for a new (or modified) system is identified and evaluated. The SA will constitute the application of selected quantitative methods to:

  • Aid in the initial determination and establishment of supportability criteria as an input to design
  • Aid in the evaluation of various design alternatives
  • Aid in the identification, provisioning, and procurement of the various elements of maintenance and support
  • Aid in final assessment of the system support infrastructure throughout the utilization phase.

The SA as part of the part of the overall system engineering analysis effort, is applied during the early phase in the life cycle and often includes the maintenance task analysis (MTA), Level of repair analysis (LORA), FMECA/FTA, reliability-centered maintenance (RCM) analysis, transportation analysis, life-cycle cost analysis (LCCA), and logistics modeling.

HEI's Supportability Engineers perform the following steps in its SA approach:
1.  Defining the the problem and analysis goals.
2.  Defining metrics, variables and data needs.
3.  Selecting appropriate techniques and modeling requirements
4.  Making recommendations, trade-offs  and break-even points
5.  Running model and running sensitivity analysis
6.  Utilizing R&M data data base.
