Group decision support system for employee performance evaluation using combined simple additive weighting and Borda

Abstract

Subjectivity in performance appraisal is almost inevitable. Subjectivity is defined as a perspective based on personal views or feelings about a thing. Eliminate subjectivity factors so that assessing objectively based on certain criteria is difficult to implement, whereas subjectivity causes unfair competition and giving rise to an uncompetitive environment. This research was conducted to reduce subjectivity in a performance appraisal using the Group Decision Support System with Simple Additive Weighting and Borda methods. Employee performance appraisal at PT. Krakatau Osaka Steel was the object of this research. The Group Decision Support System has selected the best employees from 59 employee samples taken by the Purposive Sampling method resulted the 7 best employees according to the assessors with a Decision Support System, these results are then reselected to become the 3 best employees provided by the Group Decision Support System. The results of Group Decision Support System were found that A2 was in the first place with a Borda score of 0.218336, followed by 2 other employees, namely A52 and A1, with a Borda score of 0.206507 and 0.205753, respectively.
