Analysis of M/M/1/N Queueing System with Encouraged Arrivals, Feedback, Catastrophe and Retention of Reneged Customers

This paper aims to derive the analytical solution of the truncated single-channel queue: M/M/1/N at the steady state by adding the concepts of encouraging arrivals, feedback strategy, catastrophe, and retention of reneged customers. Using the iterative method obtain the probability that there are n customers in the system, the possibility of a vacuous system, and some performance effectiveness measures. Some important queueing models are exceptional cases of this system. Some numerical values are given for the additional concepts to show the effect of the (arrival rate, and catastrophe rate) on the model so that the companies implementing this model work to reduce the harmful ones.

The educational platform in university teaching, reality and challenges experienced by the learners

E-learning can be considered as the best solution to the traditional education problems faced daily, as it is continuously changing the educational system towards a more flexible and effective learning system. It contains a wide range of applications and processes, such as Web-based learning, computer-based learning, virtual classrooms, and digital collaboration. E-learning includes the delivery of contents via Internet, intranet/extranet, audio- and videotape, satellite broadcast, interactive TV, and CD-ROM. This article presents the findings from a study carried out at an University on the experiences of using Web-based learning (educational platform) as an educational form of ICT and e-learning. The reported findings focus on the students’ challenges of and their experiences with that platform. This study concluded that the majority of students expressed their dissatisfaction with the idea of distance learning through the educational platform and considered learning via the platform as ineffective as is the case in interactive education. The study also concluded that the students' opinions about the platform give the impression that it may lack some of the required technical and functional specifications, such as methods of presenting curricula, methods of evaluation and communication with the teacher.

A Recent Treatment for M/D/1 queueing Model with Encouraged Arrivals

This paper aims to derive the analytical solution of the truncated single-channel queue: M/D/1 at the steady-state by adding the concept of encouraging arrivals. Using the iterative method and the probability generating function method obtain the probability that there are n customers in the system, the possibility of a vacuous system, and some performance effectiveness measures. Some numerical values are given for the additional concept to show the effect of the (arrival rate, encouraging arrivals) on the model so that the companies implementing this model work to reduce the harmful ones.
