The Sojourn Time Distribution in an Infinite Server Resequencing Queue with Dependent Interarrival and Service Times

We consider an infinite server resequencing queue, where arrivals are generated by jumps of a semi-Markov process and service times depend on the jumps of this process. The stationary distribution of the sojourn time, conditioned on the state of the semi-Markov process, is obtained both for the case of hyperexponential service times and for the case of a Markovian arrival process. For the gener...

Calculating Service Fitness in Service Networks

Inspired by the biological perspective of service ecosystems, we propose to define the fitness of services in service networks. In our work, we show how to calculate the service fitness from the provider perspective using locally available information as a reflection of the position of the service in the service network. For that purpose we define a fitness corridor with upper and lower bounds ...

The potential for saving energy by more precisely calculating station dwell times on commuter rail service

This paper evaluates the effectiveness of reducing scheduled station dwell time to save energy on commuter rail lines. Most commuter rail schedules include a fixed amount of dwell time (e.g. 30-seconds) at each station. For stations with higher demand the station dwell time may be up to 1 minute. Generally the station dwell time is set high enough to meet peak period passenger boarding/alightin...

Analysis of Guaranteed Service Times of Distributed Real-Time Objects

As the demands for real-time distributed systems increase, the needs for programming tools useful in development of such application systems are becoming increasingly acute. An issue that the research community has long recognized as an important technological challenge but has not shown much progress in meeting the challenge is to guarantee response times of real-time distributed systems. Two ...
