The Creation

In our research we dealt with the creation of an algorithm designed to simulate M / M / n queuing systems with endless queues. The algorithm was created in Matlab. When creating the algorithm, we proceeded according to scientific literature, according to which we transformed the formulas into the Matlab algorithm. This process also included the optimization and creation of new outputs based on the analysis of the generated data. The research output is a Matlab algorithm suitable for creating simulations of M / M / n / ∞ systems.

Traffic Conditions

In view of traffic queuing question, this article has established the dynamic queuing theory model, considered the waiting the traffic flow magnitude and the vehicles density. On this basis, through computer random simulations,we found that traffic conditions can be divided into three statuses,and found out the key conditions of formation for each status. The results can be widely promoted, and can provide advice to government

Productivity Potential

The installation of water and sewer services is an essential element of many construction projects. With an increasing number of construction projects being undertaken in metropolitan areas, delays are no longer affordable. To increase productivity in this type of construction project, workflow must be improved. This paper describes the application of lean thinking principles to improve the productivity of water and sewer service installations. To illustrate this, a case study is presented that applies these principles to water and sewer service installations performed by City of Edmonton construction crews. As well, this paper outlines a study that applies the lean thinking procedures recommended within a queuing theory model to validate the effect of the proposed improvements to productivity. Potential improvements to overall productivity will be discussed along with proposed future research.

Priority Level

Cognitive Radio Networks is an effective technology and a hot research direction which can solve the problem of deficient resource and revolutionize utilization. In order to enhance the communication efficiency, secondary users are classified by some strategy. We exploit the queuing theory model to research on the communication performance of secondary users, considering primary user as the first grade user and secondary users as other grades users. The research results indicate that the users which have lower priority level are more sensitive than those have higher priority level when primary user appears. Under Primary User Emulation Attack (PUEA), if the number of secondary users reaches 300, the waiting time would larger than 15 minutes. And if the appearance rate of PUEA reaches 4, the break-out rate would be 80%, which is much harmful for CRN.

This paper describes the methodology designed to maximize the service of medical system in hospitals. We apply the result of queuing theory to find maximum number of servers served by hospital authorities to provide oxygen. Too much waiting may be fatal to a critical patient and it may leads to increase the mortality rate than expected further a serious situation for Government and Medical authorities.
