Back Matter Pages The reasons for bypassing a Text portion of the text include: the subject is a special topic that will not be referenced later, the material can be skipped on first reading, or the level of mathematics is higher than the rest of the text.
In cases where a topic is self-contained, we opt to collect the material into an appendix that can be read by students at their leisure. The material in the text cannot be fully assimilated until one makes it Notes on "their own" by applying the material to specific problems. With this in mind, we have made problems an integral part of this work and have attempted to make them interesting as well as informative.

Theory of Probability and Mathematical Statistics Teoriya Imovirnostei ta Matematychna Statystyka The journal Theory of Probability and Mathematical Statistics is a peer reviewed international scientific journal published biannually. The Editor-in-Chief is Yu. Kukush Ukraine , L. Ralchenko Ukraine. The journal Theory of Probability and Mathematical Statistics has a long history dated from when it was founded at Taras Shevchenko National University of Kyiv by the prominent mathematicians of world-wide recognition Anatoliy Skorokhod and Mykhailo Yadrenko.

Allocation of scarce resources presents an increasing challenge to hospital administrators and health policy makers. Intensive care units can present bottlenecks within busy hospitals, but their expansion is costly and difficult to gauge. Although mathematical tools have been suggested for determining the proper number of intensive care beds necessary to serve a given demand, the performance of such models has not been prospectively evaluated over significant periods. The authors prospectively collected 2 years' admission, discharge, and turn-away data in a busy, urban intensive care unit. Using queuing theory, they then constructed a mathematical model of patient flow, compared predictions from the model to observed performance of the unit, and explored the sensitivity of the model to changes in unit size.

In queueing theory, the arrival process of customers is modeled as a random process, and the service times required from the server are modeled as random.

The model name is written in Kendall's notation. The model is the most elementary of queueing models  and an attractive object of study as closed-form expressions can be obtained for many metrics of interest in this model. The model can be described as a continuous time Markov chain with transition rate matrix. This is the same continuous time Markov chain as in a birth—death process. The state space diagram for this chain is as below. We assume that the queue is initially in state i and write p k t for the probability of being in state k at time t. Then .

Bed resources are the platform in which most medical and health resources in the hospital play a role and carry the core functions of the health service system. How to improve the efficiency of the use of bed resources through scientific management measures and methods and ultimately achieve the optimization of overall health resources is the focus of hospital management teams. This paper analyzes the previous research models of knowledge related to queuing theory in medical services. From the perspective of the hospital and the patient, several indicators such as the average total number of people, the utilization rate of bed resources, the patient stop rate, and the patient average waiting time are defined to measure the performance of the triage queue calling model, which makes the patient queue more reasonable. According to the actual task requirements of a hospital, a Markov queuing strategy based on Markov service is proposed. A mathematical queuing model is constructed, and the process of solving steady-state probability based on Markov theory is analyzed. Through the comparative analysis of simulation experiments, the advantages and disadvantages of the service Markov queuing model and the applicable scope are obtained.
