Abstract

PurposeThe purpose of the paper is to analyze reliability characteristics of batch service queuing system with a single server model that envisages Poisson input process and exponential service times under first come, first served (FCFS) queue discipline.Design/methodology/approachWith the help of renewal theory and stochastic processes, a model has been designed to discuss the reliability and its characteristics.FindingsThe instantaneous and steady-state availability along with the maintenance model of the systems subject to generalized M/Mb/1 queuing model is derived, and a few particular cases for availability are obtained as well. For supporting the developed model, a case study on electrical distribution system (EDS) has been illustrated, which also includes a comparison for the system subject to M/Mb/1 queuing model and the system without any queue (delay).Originality/valueIt is a quite realistic model that may aid to remove congestion in the system while repairing.

批量服务排队系统的可用性和维护建模

目的分析考虑泊松输入过程和指数服务时间的单服务器批服务排队系统在先到先得(FCFS)队列规则下的可靠性特性。设计/方法/途径借助于更新理论和随机过程，设计了一个模型来讨论可靠性及其特性。结果导出了广义M/Mb/1排队模型下系统的瞬时可用性和稳态可用性及其维护模型，并得到了可用性的一些特殊情况。为了支持所建立的模型，本文以配电系统(EDS)为例进行了分析，并对采用M/Mb/1排队模式的配电系统与不采用排队(延迟)模式的配电系统进行了比较。原创性/价值这是一个非常现实的模型，可以帮助在修复时消除系统中的拥塞。

期刊介绍： In today''s competitive business and industrial environment, it is essential to have an academic journal offering the most current theoretical knowledge on quality and reliability to ensure that top management is fully conversant with new thinking, techniques and developments in the field. The International Journal of Quality & Reliability Management (IJQRM) deals with all aspects of business improvements and with all aspects of manufacturing and services, from the training of (senior) managers, to innovations in organising and processing to raise standards of product and service quality. It is this unique blend of theoretical knowledge and managerial relevance that makes IJQRM a valuable resource for managers striving for higher standards.Coverage includes: -Reliability, availability & maintenance -Gauging, calibration & measurement -Life cycle costing & sustainability -Reliability Management of Systems -Service Quality -Green Marketing -Product liability -Product testing techniques & systems -Quality function deployment -Reliability & quality education & training -Productivity improvement -Performance improvement -(Regulatory) standards for quality & Quality Awards -Statistical process control -System modelling -Teamwork -Quality data & datamining
