Performance modeling for evaluation and planning of Electronic Funds Transfer Systems

The electronic funds transfer (EFT) systems promote both financial benefits for the institutions that use them and potential conveniences for their customers. EFT Systems debiting and crediting individual bank accounts from points of sale (POS) terminals in different companies and providing cash on demand 24 hours a day through automatic tellers. In the EFT system, eventual workload peaks and fluctuations can cause degradation on system performance. Hence, the performance evaluation of EFT systems has an enormous importance for electronic transactions providers, since the computing resources must be efficiently used in order to ensure high availability, reliability, scalability and security. This paper presents an stochastic model for performance evaluation and planning EFT systems processing and storage infrastructure considering load variation range. A case study is presented in order to describe the adequacy of presented approach and results.
