Decision Making using Vroom-Yetton-Jago Model with a Practical Application

Testing the Incremental Validity of the Vroom±Jago Versus Vroom±Yetton Models of Participation in Decision Making

In three samples of manager-reported decisions the Vroom±Jago model's predictions were supported. Decisions that more closely ®t the recommended decision method were rated as higher in e€ectiveness. The model was also found to account for more variance in decision e€ectiveness than the prior Vroom± Yetton model. It was also found that the Vroom±Jago model's greater precision in situational asse...

An AHP-Delphi Multi-Criteria Decision Making Model with Application to Environmental Decision-Making

Fuzzy Management of Participation in Organizations

The Fuzzy Model for Management of Participation in Organizations (FMPO), pretends to be an evolution of the Normative Vroom-Yetton Model (NVYM). It adopts the same decision processes for group problems (AI, AII, CI, CII and GII), and several of the problem attributes defined by Vroom and Jago in the NVYM. However, there are important differences between NVYM and FMPO philosophies. While the for...

Ranking Decision Making Units, using Non-radial Model, applying Bootstrap

Data envelopment analysis (DEA) is a mathematical programming method in Operations Research that can be used to distinguish between efficient and inefficient decision making units (DMUs). However, the conventional DEA models do not have the ability to rank the efficient DMUs. This article suggests bootstrapping method for ranking measures of technical efficiency as calculated via non-radial mod...

Statistics in practical decision making

This issue is devoted to statistics applied to decision making problems. The issue begins from consideration of methodological possibilities to construct regressions with meaningful and interpretable coefficients for individual predictors and shares of their importance. Ewa Nowakowska explores properties of the so-called Shapley value regression developed for adjusting regression coefficients w...
