In this paper, a study on multi-objective optimization of the cylindrical grinding process is presented. The experimental material used in X12M steel. two output parameters considered are surface roughness and removal rate (MRR). cutting mode including speed, feed rate, depth have been selected as input process. Experimental matrix by Taguchi method has to design with 27 experiments. Analysis r...

nowadays, the environmental impact of transportation project and, especially air pollution impacts, are major concerns in evaluating transportation projects. based on this concern, beside definition of traditional objective functions like total travel time and total investment cost, different type of environmental related function is considered as objective function in urban network design. in ...

This paper introduces a multi-factory scheduling problem with heterogeneous factories and parallel machines. problem, as major part of supply chain planning, includes the finding suitable factory for each job assigned jobs at factory, simultaneously. For first time, this studies multi-objective in production network which has its customers demands can be satisfied by itself or other factories. ...

The objectives of flood control, power generation, water supply and ecology for reservoir operation are neither completely coordinated nor opposed, its optimal decision-making is very complicated. This study proposed a method multi-objective optimization multi-attribute decision making (MODRO). correlation analysis was used to analyze the competitive relationship among extracted objectives, mod...

the present paper aims to investigate the effects of modularity and the layout of subsystems and parts of a complex system on its maintainability. for this purpose, four objective functions have been considered simultaneously: i) maximizing the level of accordance between system design and optimum modularity design,ii) maximizing the level of accessibility and the maintenance space required,iii...
