This paper presents a complete system model for scheduling and dispatching CORBA service requests that have hard as well as soft real-time timing requirements in a distributed environment. The model provides the methodology for expressing and enforcing time-based QoS constraints for real-time CORBA service requests. Therefore, the presented model complements the state of the art in real-time sc...

Dynamic binding, the ability to link at runtime a method call with a subprogram that depends on the class of the object, is strongly discouraged by current standards for avionics airborne systems. This is partly due to dynamic dispatching, the technique commonly used by most OO compilers to implement dynamic binding. In this paper we present some enhancements to the GNAT technology that will he...

In object-oriented programming languages, multiple dispatching provides increased expressive power over single dispatching by guiding method lookup using the values of all arguments instead of the receiver only. There have been several programming languages supporting this mechanism and they demonstrate its usefulness. However, efficient implementation of multi-methods is critical with regard t...

We present two new dispatching rules for scheduling in a job shop. These rules combine the process-time and work-content in the queue for the next operation on a job, by making use of additive and alternative approaches. An extensive and rigorous simulation study has been carried out to evaluate the performance of the proposed dispatching rules against those by the SPT rule, the WINQ rule, a ra...

In this paper, based on the analysis of the time urgency in medicine relief demand and kinds of complexity in the early period after earthquake disasters, the problem about vehicle scheduling in the medicine dispatching process is studied. A mathematical model of vehicle scheduling in the medicine dispatching process is built, which objective function is to minimize the total transportation tim...

For mobile agents to be effective in practice, they have to be securely and efficiently deployed. In this paper, we propose and discuss several route structures and methods for mobile agents that are dispatched in parallel. These schemes can protect the route information against malicious hosts and facilitate the dispatching of a large number of agents in parallel efficiently. Under noncollusio...
