Project summary

In 1996 Comprehensive Test Ban Treaty (CTBT) was open for signing that immediately posed a problem of its effective verification. As a key verification measure CTBT Protocol provides for On-Site Inspection (OSI) of a suspected event. The inspection is to be conducted by a limited number of persons within a limited time with use of a limited set of approved techniques. During the inspection the inspectors must either find features demonstrative of a clandestine nuclear test, or verify with required confidence that no such test has been conducted.

The software proposed for the development will simulate the OSI process. It can be used at various stages of the OSI preparation and conduct: personnel training, tabletop and field exercises, the provisional planning of real inspection, data management and their comprehensive analysis during real inspection.

Inspection Team Training. A test facility will be developed for the inspectors for they could examine and simulate different situations, they could encounter in the course of real inspection, play particular elements of the OSI or whole scenarios.

Development of particular inspection techniques. The questions of the applicability and efficiency of the OSI techniques in various climatic, geological and geographical conditions, and the expenditures needed, may be solved by means of computer simulation without carrying out labor-intensive and expensive field survey.

The development of integrated OSI strategy and tactics. Integrated analysis of results provided by particular OSI techniques and search for optimal strategies and tactics to be used in specific conditions will allow selecting optimal plan of the OSI conduct.

Provisional planning and optimizing strategy of inspection campaign. After CTBT Organization has received a request for inspection of a site where a suspected event took place, Technical Secretariat (TS) could use the same code to assess, for specified area, different OSI options concerning instrumentation, number of specialists in technical subgroups and so on.

Short-term OSI planning. During the inspection IT should revise its actions each day and frame a plan for the next day using data collected. Using the same program IT can model its actions and make a final optimal decision on the basis of model results.

The works under the project proposed will result in the development of the code for the OSI simulation using unit concept.

Base geoinformation system (GIS) constitutes a base, or a playground for conducting the inspection simulated – a topographical map, and implements visualization of data collected in the course of the OSI at the maps of the Inspection Area.

Module for modeling inspection activity and logistics formalizes and enters data on actions of inspectors during inspection campaign and in so doing it controls validity of the actions and maps them, keeps logistics control and accounting (time, equipment, personnel and other items required for specified actions).

The measured anomaly module models the field survey data (measured by different techniques) and inputs data to the OSI database.

The module for storing inspection data and documents organizes accounting and storage of the information gathered during the inspection in a unified database. The information from the database can be visualized in appropriate form by means of the data visualization module.

For achieving the goals the following tasks are to be solved:

1. Development of the techniques models of the first stage of the OSI for their realization in the code;
2. Creation of the simulating code implementing the models developed;
3. Development of a set of typical OSI scenarios;
4. Documentation of the code and other activities.
