The object of research is intelligent decision making support systems. Processing different types intelligence from a variety information sources requires significant computational operations with strict time constraints. It leads to the search for new scientific approaches processing various geospatial increase efficiency special purpose This work solves problem developing methodological appro...

We study how to estimate real time queue lengths at signalized intersections using intersection travel times collected from mobile traffic sensors. The estimation is based on the observation that critical pattern changes of intersection travel times or delays, such as the discontinuities (i.e., sudden and dramatic increases in travel times) and non-smoothness (i.e., changes of slopes of travel ...

Nowadays, with the increasing pressure of the competitive business environment and demand for diverse products, manufacturers are force to seek for solutions that reduce production costs and rise product quality. Cellular manufacturing system (CMS), as a means to this end, has been a point of attraction to both researchers and practitioners. Limitations of cell formation problem (CFP), as one o...

Queuing theory is the one of the classical mathematical tool for study waiting lines or queues. In queuing theory a mathematical model is constructed to find various queue characteristics like average waiting time, mean queue length and number of the customers etc. Infact, waiting for service in queues has become an integral part of our daily life. Queues are often undesirable as they cost time...

Based on queuing theory we develop analytical approximations for the average packet transfer time of a store-and-forward and a cutthrough buffer insertion ring with two client traffic priorities. These types of rings are architectural alternatives for resilient packet rings (RPR) which transport data (e.g., IP) packets over optical media. We use the approximations for a delay comparison of both...

Purpose Each production process in construction is closely connected with the question of costs and deadlines. In every project an investor or customer, as well as the construction company, has to meet the planned completion date and the estimated costs associated with the construction. In practice, determining the duration of construction at minimum costs is still not based on the reliable cal...

AbsmcfA closed-form decomposition approximation for finding the data performance in voicddata queuing systems is presented. The approximation is based on Courtois’ decompositiodaggregation techniques and is applied to Senet hybrid multiplexing, movable boundary frame allocation schemes. The approximation is applied to both infinite and finite buffer systems. In the former case the app...

In this paper we consider the optimal trade-off between average transmission power and average queueing delay for a single user transmitting data over a wireless fading channel. In particular we study the behavior of this trade-off in the regime of asymptotically large power and small delay. Our focus is on channels which require infinite power to minimize the average delay. For such channels, ...

The network delay has a huge impact to the quality of a networked control system. This paper investigates modelling the network delay incurred by control system packets traversing a Mobile Ad Hoc Network from a plant to a controller using the queuing theory. Control systems can become unstable if information is lost or delayed so in this paper we compare voice traffic modelling with control pac...
