priority queues have a great importance in the study of computer communication networks in which different types of traffic require different quality of service standards. the discrete-time non-preemptive priority queuing model with priority jumps is proposed in this paper. on the basis of probability generating functions mean system contents and mean queuing delay characteristics are obtained....

This paper proposes a control method for the multi-agent pickup and delivery problem (MAPD problem) by extending priority inheritance with backtracking (PIBT) to make it applicable more general environments. PIBT is an effective algorithm that introduces each agent, at timestep, agents, in descending order of priority, decide their next neighboring locations timestep through communications only...

Abstract The good of those who are worse off matters more to the overall than better does. But being one’s fellows is not itself bad; nor inequality do differences in well-being matter when lower an absolute sense. Instead, relatively worse-off weighs heavily better-off does, virtue fact that former off. This paper articulates and defends view just described.
