Dried samples were ground and different size particals screening were used

Author: Tamer EREN, Ertan GÜNER Publishing Date: 2006 E-ISSN: 2147-9364 Volume 21 Issue 1_2 ABSTRACT: In this study bicriteria identical two parallel machine scheduling problem is considered. The objective function of the problem is minimization of the weighted sum of completion time and maximum tardiness. Total completion time and maximum tardiness are widely used performance measures in scheduling literature. An integer
