many studies are performed by researchers about shell and tube heat exchanger but the multi-objective big bang-big crunch algorithm (mobba) technique has never been used in such studies. this paper presents application of thermal-economic multi-objective optimization of shell and tube heat exchanger using mobba. for optimal design of a shell and tube heat exchanger, it was first thermally model...

integrated production-distribution planning (pdp) is one of the most important approaches in supply chain networks. we consider a supply chain network (scn) to consist of multi suppliers, plants, distribution centers (dcs), and retailers. a bi-objective mixed integer linear programming model for integrating production-distribution designed here aim to simultaneously minimize total net costs in ...

Abstract This paper examines the idea of objective phenomenology , or a way understanding phenomenal character conscious experiences that doesn’t require one to have had kinds under consideration. My central thesis is structural facts about experience—facts characterize purely how are structured—are facts. I begin by precisifying and diagnosing what makes any given fact subjective. Then defend ...
