The object-code compatibility problem in VLIW architectures stems from their statically scheduled nature. Dynamic rescheduling (DR) [1] is a technique to solve the compatibility problem in VLIWs. DR reschedules program code pages at rst-time page faults i.e., when the code pages are accessed for the rst time during execution. Treating a page of code as the unit of rescheduling makes it suscepti...

Train rescheduling plays a vital role in railway operation. Many factors should be considered in the train rescheduling process and train class, delayed time, remaining distance and current position are the most common ones. There are usually different measures aiming at corresponding factors and combinations of the measures with different priorities compose various train rescheduling strategie...

Optimization of timetable is the need of the day for the rescheduling and routing of trains in real time. Trains are scheduled in parallel with the road transport vehicles to the same destination. As the number of trains is restricted due to single track, customers usually opt for road transport to use frequently. The air pollution increases as the density of vehicles on road transport is incre...

In this paper, we consider the problem of fast and efficient dynamic scheduling of bursts that belong to different classes of priority in wavelength-division multiplexing (WDM)based optical burst switching (OBS) networks with limited optical buffers. In OBS networks, control and data components of a burst are sent separately with a time gap to ensure that resources such as wavelengths and fiber...

Abs t rac t . We outline the formal modelling of a software system to support the scheduling and rescheduling of trains. The current (prototype) system supports only centralized rescheduling, but in practice rescheduling is done on an area basis, and a distributed system is required. Developing a distributed system involves the notions of delegability of functions to adjust schedules and distri...

This paper draws an overview of various quantitative rescheduling models that have been developed in past research in dealing with delay management of passenger railway services. In general, the quantitative models highlighted aimed to reduce or minimize the service delays experienced by passengers when service disruptions occur. In many literatures observed, the delay management problems are f...

This paper presents a linear programming (LP) based approach for the alleviation of line overloads by generation rescheduling and load shedding. The algorithm is based on solving a linearized set of optimal equations. The objective function for generation rescheduling is to minimize the linearized system operating cost while satisfying the system equality and inequality constraints. In respect ...

Unplanned and abnormal events may have a significant impact on the feasibility of plans and schedules which requires to repair them ‘on-the-fly’ to guarantee due date compliance of orders-in-progress and negotiating delivery conditions for new orders. In this work, a repair-based rescheduling approach based on the integration of intensive simulations with logical and relational reinforcement le...
