Task: Assign MoEs to Candidate Solutions
This task focuses on assigning Measures of Effectiveness (MoE) values to each of the candidate solutions.
Disciplines: System Engineering Requirements
Purpose
In order to compare the different solutions via weighted objectives analysis each candidate solution needs to be characterized by a set of normalized, dimensionless values (MoE) which take into consideration the effectiveness with regard to the previously defined assessment criteria.

      Main Description

      The Measure of Effectiveness (MoE) describes how effective a solution candidate is for a particular assessment criterion. The MoE is a normalized value computed using the utility curve and the nominal value specified for the solution candidate.

      The nominal values are typically determined from equipment specifications or derived from calculations based upon the relevant solution.

      The assignment of MoEs to each candidate solution is a prerequisite for the identification of the preferred solution.

      Steps
      Select an assessment criterion
      There will be a utility curve associated with each assessment criterion. Select an assessment criterion and perform the following steps.
      Determine the nominal values for each solution candidate
      For the subject assessment criterion, determine the nominal values for each solution candidate. This information may be taken from equipment specifications, measurements or analysis.
      Compute MoE for each solution candidate
      Convert the nominal values for each solution candidate to the associated Measure of Effectiveness by applying the utility curve for the subject criteria.
      Repeat analysis for each assessment criterion
      Repeat the previous three steps for each assessment criterion to complete the assessment.
