We relax some assumptions of the traditional scheduling problem and suggest an adapted meta-heuristic algorithm to optimize efficient utilization of resources and quick response to demands simultaneously. We intend to bridge the existing gap between theory and real industrial scheduling assumptions (e.g., hot metal rolling industry, chemical and pharmaceutical industries). We adapt and evalua...

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 ...

often in modeling the engineering optimization design problems, the value of objective function(s) is not clearly defined in terms of design variables. instead it is obtained by some numerical analysis such as fe structural analysis, fluid mechanic analysis, and thermodynamic analysis, etc. yet, the numerical analyses are considerably time consuming to obtain the final value of objective functi...

this article addresses a single row facility layout problem where the objective is to optimize the arrangement of some rectangular facilities with different dimensions on a line. regarding the np-hard nature of the considered problem, a hybrid meta-heuristic algorithm based on simulated annealing has been proposed to obtain a near optimal solution. a number of test problems are randomly generat...

The recent years have witnessed phenomenal growth of interest in solving many-objective optimization problems. Many-objective Optimization Problems (MaOPs) are the Multi-objective Optimization Problems (MOPs) with typically more than three objectives. For instance, the designing of an electric motor involves satisfying at least seven objectives simultaneously. These include the size or weight o...

conclusions the current meta-analysis showed an association between frequency of gg genotype of pnpla3 and the risk of development of chc in various populations throughout the world. results five hospital-based case-control studies were included in the final analysis. the overall frequency of pnpla3 gene polymorphisms was 20.4% (205/1005) in chc and 10.23% (53/518) in controls. the summary odds...

objective(s):this study aims to investigate the relationship between human papillomavirus (hpv) and breast cancer using meta- analysis. materials and methods: relevant studies were identified reviewing the national and international databases. we also increased the search sensitivity by investigating the references as well as interview with research centers and experts. finally, quality assessm...
