This paper presents an experimental study for evaluating the decision support value of queueing network (QN) based simulation models for information system design performance. For illustration, queueing network simulation models have been extracted corressponding to three annotated design alternatives of a selected case study. The design alternatives are produced using logical requirements of the selected system. The performance of each alternative is then predicted using quantifiable parameters considering the dynamics of the system such as service time, waiting time and number of entities waiting in the system. In particular, results have shown that the first alternative performs better than the other two in terms of the selected parameters. In general, the case study revealed that QN-based simulation models are capable to distinguish the performance of design alternatives in terms of selected parameters and under given assumptions. This also means that the use of simulation may lead to better designed information systems.

A metrics-based approach to the testing process and testability of object-oriented software systems Yurga, Tolga; Doğru, Ali Hikmet; Department of Information Systems (2009) This dissertation investigates the factors that affect testability and testing cost of object- oriented software systems. Developing a software program which eases the testing process by increasing testability is crucial. Also, to assess whether or not the testing effort and cost consumed or planned is adequate or not is another critical matter this dissertation aims to answer by composing a new way to evaluate the links between software design parameters and testing effort via source-based metrics. An auto...
A method for decentralized business process modeling Türetken, Oktay; Demirörs, Onur; Department of Information Systems (2007) This thesis study proposes a method for organizations to perform business process modeling in a decentralized and concurrent manner. The Plural method is based on the idea that organizations’ processes can be modeled by individuals actually performing the processes. Instead of having a central and devoted group of people to understand, analyze, model and improve processes, individuals are held responsible to model and improve their own processes concurrently. These individual models are then integrated to f...
A performance study on real-time IP multicasting Demirci, T; Bilgen, Semih (2003-07-03) In this paper we investigate the performance of Internet Group Management Protocol version 3 (IGMPv3) and Real Time Transport Protocol (RTP) for various scenarios. For this purpose, a network simulator is developed using C++. As it is important to evaluate protocol performances under realistic conditions, the simulation models and network traffic models that are used in the simulations are developed to reflect real life behavior. The simulation models are verified and the performance results obtained are co...
A new algorithm and computation approach for economic dispatch with prohibited operating zones in power systems Cetinkaya, N; Urkmez, A; Erkmen, İsmet; Yalcinoz, T (2005-01-01) This paper presents a new algorithm and computation approach to solve the economic load dispatch (ELD) in electrical power systems. We applied a new power formula to solve the LLD problem. If production units cost Curves are represented property then ELD becomes More Correct. In this respect we assumed that production units have prohibited operating zones. Cost curves of the production units are generally accepted as piece-wise quadratic function. The power production is cheaper since we do not use the prod...
A finite field framework for modeling, analysis and control of finite state automata Reger, Johann; Schmidt, Klaus Verner (Informa UK Limited, 2004-09-01) In this paper, we address the modeling, analysis and control of finite state automata, which represent a standard class of discrete event systems. As opposed to graph theoretical methods, we consider an algebraic framework that resides on the finite field F-2 which is defined on a set of two elements with the operations addition and multiplication, both carried out modulo 2. The key characteristic of the model is its functional completeness in the sense that it is capable of describing most of the finite st...
