Эта задача фокусируется на назначении значений измерителей эффективности (MoE) для оценки каждого из вариантов решения.

Дисциплины: System Engineering Requirements

Назначение

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.

Основное описание

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.

Шаги

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.

Update the Trade Study Report

Update the relevant section of the Trade Study report to capture the matrix of MoEs.
