Reliability and sensitivity analysis for a banking company transmission system

Abstract

This article studies a case of the banking company in Taiwan to measure the service performance by adopting reliability analysis. The service performance focuses on sending transaction data from one source (headquarters) to multiple sinks (bank branches) for a banking company transmission system. A stochastic flow network consisting of edges (transmission lines) and nodes (Internet data center or bank branches) is constructed to model such a computer system. The service-level agreement is a contract that requirements should be promised by the Internet service provider. Also, the bank needs to satisfy the customers’ requirements through the banking company transmission system. System reliability, which is defined as the probability of demand satisfaction, is studied as a key performance indicator for measuring service level of the banking company transmission system. Subsequently, sensitivity analysis is adopted to investigate the key transmission line that affects the system reliability most significantly. The system supervisor can make a decision for banking company transmission system to enhance the important edges for improving system reliability.
