The cost of building a new system is usually quite high and without a proper design, a mismatch might occur between the proposed system and the actual system delivered. One aspect that is important to be investigated prior to the system implementation is its performance. A simulation program could be built to obtain the performance characteristics of the new system, but constructing such a prog...

Telecommunications carriers suffer large-scale outages that impact hundreds of thousands of subscribers by the improper deployment or operation of otherwise faulttolerant designs. This paper gives examples of such outages in telecommunications signaling, transmission, and power systems. In spite of seven years industry tracking of largescale outages at the national level, the survivability of t...

Numbers of software quality measurement system have been implemented over the past few years, but none of them focuses on telecommunication industry. Software quality measurement system for telecommunication industry was a system that could calculate the quality value of the measured software that totally focused in telecommunication industry. Before designing a system, quality factors, quality...

At this time, telecommunication networks are present everywhere. These networks are not only rather complex, but they are also made up of different components. That is the reason telecommunication network management (TNM) is so relevant. This paper deals with two important aspects of telecommunication network management: managed objects and expert system rules. Definition of objects is based on...

The Intelligent Transportation System (ITS) provides wireless and mobile communication between vehicles and infrastructure to improve the safety of transportation and make the journey more enjoyable. This system consists of many fixed and mobile nodes (Vehicles, Trains, Vessels, Air planes), Wireless and Wired Telecommunication Technologies to exchange information between mobile nodes or betwee...

the hierarchical hub location problem is encountered three-level network that is applied in production-distribution system, education system, emergency medical services, telecommunication network, etc. this paper addresses the hierarchical hub covering problem with single assignment accounting for mandatory dispersion of central hubs restriction as a special case. this formulation with incorpor...
