The development of our modern societies needs more and more involvement of computers in managing highly complex and (safety-)critical tasks, e.g., in telecommunication, chemical and physical process control, transportation systems, etc. It is essential to be able to produce reliable hardware and software systems, since any erroneous behaviour can have catastrophic (economical and human) consequ...

As a comparatively cost effective, clean, and safe method of transportation, international shipping offers an important means of moving goods internationally and enables other activities such as leisure cruising.1 Many factors contribute to the development of international shipping. As an example, the evolution of ship propulsion has progressed from sailing ships to steam ships powered by coal ...

In the current growth of information technology (IT), without realizing, smart cards have been brought as an ideal device for any transaction such as transportation, healthcare, ecommerce, telecommunication, banking and many other applications. Smart card improved the quality of services in terms of security and customization for users. Recognition of aspects which affect on smart card usage is...

During the last 30 years, Turkey has undergone profound economic and social transformations, including fundamental shifts from the state-oriented economy to the market-oriented economy; large scale modernization investments in telecommunication and transportation services; and the low-intensity ongoing armed-conflict concentrated in the country’s Southeastern Region. For such a period, using th...

The global economy changed considerably in recent years with important consequences for central banking. During the last half of the previous century the world economy was characterised by a process of liberalisation, deregulation and eventually globalisation, i.e. a process through which an increasingly free flow of ideas, people, goods, services and capital leads to the integration of economi...

Dramatic advances in computer and communication technologies have greatly promoted the growth of embedded telecommunication systems. More and more critical applications, such as banking and financial services, remote patient monitoring systems, transportation, etc., are being developed. The software for these applications is becoming increasingly sophisticated and complex and this trend will ac...

Drinking water for human health and well-being is crucial. Accidental and intentional water contamination can pose great danger to consumers. Optimal design of a system that can quickly detect the presence of contamination in a water distribution network is very challenging for technical and operational reasons. However, on the one hand improvement in chemical and biological sensor technology h...

Many reactive control systems consist of a large number of similar interacting objects; these objects can be often grouped into classes. Such interacting process classes appear in telecommunication, transportation and avionics domains. In this paper, we propose a modeling and simulation technique for interacting process classes. Our modeling style uses well-known UML notations to capture behavi...

Many real world systems (electric power, transportation, telecommunication, etc) are multistate systems composed of multistate components in which system reliability can be computed in terms reliabilities of its components. Such systems may be regarded as flow networks whose arcs (components) have independent, discrete, and multi-valued random capacities. An arc can, at different conditions, be...

The purpose of this paper is to formally describe new optimization models for distributed telecommunication networks. Modern distributed networks put more focus on the processing of information and less on the actual transportation of data than we are traditionally used to in telecommunications. This paper introduces new approaches for modelling decision support at operational, tactical and str...
