Evaluation of Waterside Security processes and systems by modelling and simulation

摘要

Many who are interested in the topic of Waterside Security focus primarily on the detection of threats. This may seem like a logical focal point, but the ideal starting point should be to understand the system-of-systems with which security is to be ensured so that e.g. threat detection can be analysed within the broader context. For this purpose it is necessary to have a tool that can consider all issues relating to Waterside Security, evaluate alternatives and draw conclusions before it is attempted to specify or acquire solutions to security problems. Such a tool can be used not only to otptimise a protection system, but also to point out where system shortcomings are. From there it can become evident where new solutions are required and thus where technology and development effort should be spent. A model is presented here with which it has been attempted to capture all important elements relating to the design and implementation of solutions to Waterside Security problems. The aim of the model is to create a tool which gives understanding to the relatively new field of Waterside Security rather than acting as an operational planning tool. For that purpose, the model contains elements representing (1) the environment in which the threat and the systems operate, (2) the potential threats, (3) the protection system hardware and (4) the processes by which the systems are operated. This gives a complete picture of the influence that each part has in the performance of the total system-of-systems. Performance of sub-functions such as detection, classification, tracking, interception and neutralisation can be individually analysed and system effectiveness can be compared to desired or practical benchmarks. The model is developed in a block-based modelling environment which makes provision for continuous processes (such as movement) and discrete processes (e.g. command and control). Detail will be given on the model structure, individual model elements and the user int--erface. Also simulation results will be presented for a number of different scenarios, ranging form low-level equipment performance to the response for complex combined above and below water threats.
