Abstract

Executive Summary: The software contained in this package, termed POSAT (Police Officer Standards and Training) is the prototype knowledge-base decision support system developed specifically for the Utah State Police Academy. All police officers must be certified annual for the use of radar guns. This self-study computer program is intended to reduce the cost of providing field training for hundreds of police officers each year. By installing the POSAT software at remote locations, polic officers within a certain districut need only to travel to the nearest remote testing sight to take the exam and renew their radar certification. POSAT automatically transmits the exam results to the mainframe computer located in Salt Lake City, where they can be evaluated, and notices of valid re-certification can be distributed to the officers who took the exam. POSAT was constructed from a custom designed expert system kernet using object oriented technologies and languages (C++). Ther kernet is completely event driven, and operates under rule, action, and variable objects. Each of the objects derive their knowledge from either user input, or external modules that provide the knowledge automatically (via fact bases, or remote data bases). POSAT was then implemented under the Microsoft Windows operating system. As a result, the software can administer intelligent exams and context sensitive advice through the expert system kernel, as well as take advantage of the friendly interface inherent to Windows programs, multimedia support such as digitized photos, movie clips, animation, and other forms of interactive teaching methodologies that are not available in other environments. This manual briefly describes the features in POSAT. It explains how to install the program on your computer system, and how to start and quit the program. It also includes information about the screens you will see and the appropriate responses needed to navigate the program. This manual assumes that you are familiar with the basic terminology and procedures for using Microsoft Windows version 3.1 or later. It also assumes that you have set up the Window soperating environment on your computer system.
