In this paper, we address the issue of ordering events by simultaneously considering three separate heuristics using fuzzy methods. Combinations of the following three heuristic orderings are employed: largest degree, saturation degree and largest enrollment. The fuzzy weight of an event is used to represent how difficult it is to schedule. The decreasingly ordered events are sequentially chose...

Compiler writers continue to search for ways to use the ever-increasing number of parallel functional units in modern microarchitectures. The most popular approach today is to build a tracebased instruction scheduler, since they are effective and can be conceptually simple to implement. DAG-based schedulers that look along multiple control paths, instead of along just one as in a trace-based sc...

Passenger railway operations are based on an extensive planning process for generating the timetable, the rolling stock circulation, and the crew duties for train drivers and conductors. In particular, crew scheduling is a complex process. After the planning process has been completed, the plans are carried out in the real-time operations. Preferably, the plans are carried out as scheduled. How...

Real world systems can be thought of as structures of activities that require resources in order to execute. Costs are reduced when resource levels are kept low, but this can lead to competition for resources that can cause poor system performance. Careful allocation of resources can improve system performance by enabling more efficient use of resources. This paper proposes that resource schedu...

Metaschedulers can distribute parts of a Bag-of-Tasks (BoT) application among various resource providers in order to speed up its execution. The expected completion time of the user application is then calculated based on the run time estimates of all applications running and waiting for resources. However, due to inaccurate run time estimates, initial schedules are not those that provide users...

Nowadays, the manufacturing industry is constantly changing. Production systems must operate in a highly dynamic environment where unexpected events could occur and create disruption, making rescheduling inevitable for companies. Rescheduling models are fundamental to robustness of production processes. This paper proposes model address caused by events, aiming achieve zero-defect (ZDM) concept...
