The DNA contained in every living cell not only stores the genetic information; it functions in a complex molecular network that can condense, transcribe, replicate and repair genes. The essential role played by the sequence dependent structure and deformability of DNA in these basic processes of life, has received increasing attention over the past years. The present work aims at better unders...

Industrial and academic interest converge on scheduling flow shops with sequence- time-dependent maintenance. We posit that anticipatory, integrated of operational maintenance tasks leads to superior performance purely ‘wait-then-fix’ handling the tasks. Motivated by an industrial problem (sequence dependent) setup times, maximum separation constraints, a combination time- dependent tasks, this...

in this paper, three-stage assembly flowshop scheduling is considered with respect to minimizing bi-objectives, namely mean flow time and mean tardiness. this problem is a model of production systems, which several production operations are done simultaneously and independently, and then produced components are collected and transferred to an assembly stage for the final operation. in this mode...
