Design optimization of cutting parameters when turning hardened AISI 4140 steel (63 HRC) with Al2O3+TiCN mixed ceramic tool
(Elsevier Sci Ltd, 2007)Due to their high hardness and wear resistance, Al2O3-based ceramics are one of the most suitable cutting tool materials for machining hardened steels. However, their high degree of brittleness usually leads to inconsistent ... -
A multicriteria flowshop scheduling problem with setup times
(Elsevier Science Sa, 2007)Most of research in production scheduling is concerned with the minimization of a single criterion. However, scheduling problems often involve more than one aspect and therefore require multicriteria analysis. In this ... -
Minimizing total tardiness in a scheduling problem with a learning effect
(Elsevier Science Inc, 2007)Minimizing of total tardiness is one of the most studied topics on single machine problems. Researchers develop a number of optimizing and heuristic methods to solve this NP-hard problem. In this paper, the problem of ... -
