The phenomena are balking can be said to have been observed when a customer who has arrived into queuing system decides not join it. Reverse is particular type of wherein the probability that will balk goes down as size up and vice versa. Such behavior in investment firms (insurance company, Mutual Fund Company, banks etc.). As number customers firm up, it creates trust among potential investor...
This paper presents an analysis for an queueing system with customer behaviour, balking and reneging. Arriving customers balk with a probability and renege (leave the queue after entering) according to some distribution. Balking means that customers do not enter in the system, when queue is too long. Reneging means that a customer enter in the system, wait for some time and leave the system wit...
We use sample path arguments to derive convexity properties of an M/M/S queue with impatient customers that balk and renege. First, assuming that the balking probability and reneging rate are increasing and concave in the total number of customers in the system (head-count), we prove that the expected head-count is convex decreasing in the capacity (service rate). Second, with linear reneging a...
In order to investigate supply chain coordination and decision under customer balking stochastic demand, the article considers a two-echelon consisting of one manufacturer with risk-neutral retailer develops two models in centralized decentralized system three contracts are designed coordinate optimal price strategies obtained. The results show that revenue cost-sharing contract can price-depen...
We consider an M/PH/1 queue with workload-dependent balking. An arriving customer joins the queue and stays until served if and only if the system workload is no more than a fixed level at the time of his arrival. We begin by considering a fluid model where the buffer content changes at a rate determined by an external stochastic process with finite state space. We derive systems of first-order...
In this paper, we study an M/M/2 queueing system with balking and two heterogeneous servers, Server 1 and Server 2. Customers arrive according to a Poisson process and form a single waiting line. Two parallel servers provide heterogeneous exponential service to customers on a firstcome first-served basis. It is assumed that Server 1 is perfectly reliable and Server 2 is subject to breakdowns. F...
Consider a single-server queue with a renewal arrival process and generally distributed processing times in which each customer independently reneges if service has not begun within a generally distributed amount of time. We establish that both the workload and queue-length processes in this system can be approximated by a regulated Ornstein-Uhlenbeck (ROU) process when the arrival rate is clos...
1.2. Priorities with Delays (PD) If the objective function is FS(π), i.e., involves only the SL, then according to intuition we may want to impose a delay slightly smaller than the AWT for certain call types, to increase their chance of abandonment before the AWT in case they have to wait, which would in turn improve the quality of service to the remaining customers in terms of SL and average w...
This paper studies the customers’ equilibrium balking behavior in some single-server Markovian queues with two-stage working vacations. That is, the server starts taking two successive working vacations when the system becomes empty, during which he provides low-rate service but maintains different service rates in the two-stage vacations. Based on different precision levels of system informati...
Epidemiological studies can be used to identify risk factors for livestock welfare concerns but have not been conducted in the cow-calf sector for this purpose. The objectives of this study were to investigate the relationships of 1) herd-level management, facilities, and producer perspectives with cattle health and behavior and stockperson handling and 2) stockperson handling on cattle behavio...
