This paper investigate a queueing model where in customers arrive in batches according to compound Poisson process with rate λ and are served one by one in FIFO basis. All incoming customers demand the first ’essential’ service wherein only some of them demand the second ’optional’ service. The service times of both essential and optional services follow arbitrary(general)distribution with diff...

The aim of this paper is to analyze Bi-level threshold policy of M/(G1, G2)/1 with single vacation (SV) queue in a fuzzy environment. A mathematical Non linear programming (NLP) method is used to construct the membership function of the system characteristic in which the batch arrival-rate, expected group size, setup time, vacation time, service time for first essential service(FES), service ti...

We consider a randomized policy to control the M/G/1 queueing system with an unreliable server, second optional service and general startup times. The server is subject to breaking down according to a Poisson process, and the repair time obeys a general distribution. All arrived customers demand the first required service, and only some of the arrived customers demand the second optional servic...

This paper examines firms’ product policies when they sell an add-on (Internet service) to a base good (hotel rooms) under vertical differentiation (fourvs. three-star hotels). Theoretical analysis uncovers the differential roles of add-ons for vertically differentiated firms. A firm with higher base quality always sells an add-on as optional so that higher-taste consumers self-select to buy it...

There has been a precipitous decline in the number of rural communities across Canada providing local maternity care. The evidence suggests that the outcome for newborns may be worse as a result. There is also an emerging understanding of the significant physiological and psychosocial consequences for rural parturient women. Because they cannot plan for birth with any certainty, many of them ex...

This document defines mechanisms that provide an asynchronous message notification delivery service for the Network Configuration protocol (NETCONF). This is an optional capability built on top of the base NETCONF definition. This document defines the capabilities and operations necessary to support this service. Chisholm & Trevino Standards Track [Page 1] RFC 5277 NETCONF Event Notifications J...
