The scheduling literature reveals that majority of the studied problems are for deterministic case where all parameters jobs known in advance and fixed. However, some real-world environments, assumption fixed is not valid since job uncertain. An uncertain parameter can be modelled as a random variable within interval with lower upper bounds, called bounded. objective this paper to review invest...

<p style='text-indent:20px;'>This paper considers single-machine scheduling problems with variable processing times, in which the actual time of a job is function its additional resources, starting time, and position sequence. Four arising from two criteria (a cost total resource consumption cost) are investigated. Under linear convex functions, we provide unified approaches consequently ...

Workspace analysis is one of the most important issues in the robotic parallel manipulator design. ‎However, ‎the unidirectional constraint imposed by cables causes this analysis more challenging in the cabledriven redundant parallel manipulators. Controllable workspace is one of the general workspace in the cabledriven redundant parallel manipulators due to the dependency on geometry parameter...
