On the Adequacy of Performance Models in an Adaptive Border Inspection Management System

In this paper, we present an approach to validation of system performance models for a Border Inspection Management System (BIMS), which guide the tradeoff between the throughput and security requirements. System models used to analyze the operational status of an application and plan for a potentially optimized execution are diverse and increasingly complex. Yet, the practice of software engineering teaches us that optimal operational behavior can be correlated with the simplicity of design and implementation. Adaptive systems are more complex because they typically include monitoring, analysis, planning, and execution (MAPE) loop. Therefore, striving for the "simplest" model that enables appropriate adaptive control actions is a legitimate research direction.
