Table 2 and Fig. 4 summarize the related literature on obtaining passenger travel time, schedule synchronization, first and last train optimization, and energy consumption, respectively.
To provide better service after summarizing and analyzing the operational updating model, the schedule synchronization, cyclic timetable, minimal energy consumption, and timetable recovery from the disruption are considered as new aspects for the tactical and operational planning stage.
Modern operating systems provide management services (e.g., scheduling, synchronization) for such multithreaded processes.
We will cover the basics of operating systems, namely structure, concurrency, scheduling, synchronization, memory management, filesystems, security and networking.
This model allows the designer to experiment with various characteristics of real-time operating systems (RTOSs), such as scheduling, synchronization, and resource allocation.
Execution times have been continuously hampered by the variability of computer performance, specially for parallel programs which are affected by data races, thread scheduling, synchronization order, and contention of shared resources.
Achieving scalability required extensive experimentation with scheduling and synchronization methods to mitigate serialization.
The instant scheduling reduces synchronization breaks due to unexpected retrieval delays during the presentation.
The modularity and parallelism of dataflow representations make them suitable for key aspects of design exploration and optimization, such as efficient scheduling, task synchronization, memory and power management.
However, the execution of various portions of the control system on multiple physical resources represents a challenge as for the control task scheduling and synchronization perspectives.
The language allows an elegant formulation of a broad class of problems while exposing substantial parallelism, however, its non-strict semantics require fine-grain dynamic scheduling and synchronization making an efficient implementation on conventional parallel machines challenging.
