A Retrial Queue with a Constant Retrial Rate,Server Downs and Impatient Customers

ABSTRACT

In this paper, we consider a retrial queueing system consisting of a waiting line of infinite capacity in front of a single server subject to breakdowns. A customer upon arrival may join the queue (waiting line) or go to the retrial orbit (another queue) to retry for service after a random time. Only the customer at the head of the retrial orbit is allowed to retry for service. Upon retrial, the customer enters the service if the server is idle; otherwise, it may go back to the retrial orbit or leave the system (become impatient). All the interarrival times, service times, server up times, server down times and retrial times are exponential, and all the necessary independence conditions in these variables are assumed. For this system, we provide sufficient conditions under which, for any given number of customers in the orbit, the stationary probability of the number of customers in the waiting line decays geometrically. We also provide explicitly an expression for the decay parameter.     

民事再审之诉：是否会“水土不服”？

民事再审之诉是大陆法系国家普遍采取的纠正错误判决、裁定的救济手段。我国目前的民事再审制度存在申请再审难等问题,借鉴这一制度有助于改善我国目前的再审问题,但在引进这一制度时必须考虑我国目前的法制环境、立法现状、传统法律文化等诸多因素可能造成的影响,从而克服“水土不服”的问题,真正为我国所吸收。     

论民事再审程序提起的主体

针对民事再审程序提起主体的若干争议问题 ,本文认为人民法院对本院已经发生法律效力的判决、裁定 ,其提起再审程序的主体既不是本院院长 ,也不是审判委员会 ,而是“本法院”。法律应当规定地方人民检察院对同级人民法院已经发生法律效力的判决、裁定 ,发现有法定抗诉情形的 ,有权直接向同级人民法院提出抗诉 ,而没有必要提请上级人民检察院提出抗诉。当事人作为提起民事再审程序的主体地位应当得到肯定和保障     

对我国发回重审制度的思考

文章认为我国的发回重审制度在设置和具体运行过程中,明显带有司法行政化色彩和干涉司法独立的倾向,严重影响司法公正和效率,没有达到发回重审制度的目的。在比较评析国外重新审理制度规定基础上,提出了重构我国发回重审制度的设想。
