• Field of Research: 

Cost/Quality management of overall service networks, based on telecommunication and computer networks, with emphasize on networks with quality of service guarantees.

3. Description, including main research challenges

Research objectives

4

• Investigation and development of performance and management conceptual, mathematical and simulation models, including parameters of users’ behavior, technical characteristics and the socio-economic environment;

• Investigation and modeling of dependences between cost and quality;

• Research on correspondent indicators and methods for their estimation, prediction and forecasting.

4. Progress (1/2)

5

4.1. An integrated Network Performance Model, of telecommunication network, with quality of service guarantees including human factors and technical characteristics, and allowing prediction of values of key QoS indicators, is proposed. These predictable indicators include:• Traffic Relative Cost, of the one paid erlang,

from Service Providers’ point of view;• Cost/Efficiency Ratio;• Cost/Effectiveness Ratio.

4. Progress (2/2)

6

4.2. Models and computer programs for these indicators prediction are developed and numerical results are presented. 

 

5. Outlook

7

• The name of the Taskforce has to be change to: Cost/Quality management, following the results received.

Investigation and development of:• Other overall service network Cost/Quality

indicators, models and computer programs, and comparisons among indicators;

• Overall service network QoS and QoE indicators, from users’ perspective.

6. Publications, presentations and meetings
