Dispute Performance Index gen.

[leka11]

помогите пожалуйста перевести Dispute Performance Index
под Dispute Performance здесь, вероятно, подразумечается урегулирование споров (эффективность механизмов), но как это связать с Index ???

контекст -
Using this information, we first extended our analysis by applying a well known dispute prediction model (Dispute Performance Index — DPI) to determine whether a project is prone to disputes (Diekmann and Girard, 1995). We further investigated the possible reasons for the poor project performance, including the likelihood of project disputes based on the actual data collected

еще добавлю контекста

The DPI predicts construction project performance and its sensitivity to disputes on a scale from 0% to 100% (see Figure 9). The higher the value of DPI, the less likely are contract disputes.

может быть назвать коэффициент вероятности предотвращения (избежания) споров?
