Cost/Schedule Risk Analysis of Engineering Development Phase for Army User Equipment of GPS.

Abstract

The NAVSTAR GPS is a space-based radio navigation system that will permit users to determine accurately their three-dimensional position and velocity in real time. The GPS will consist of a space segment (satellites), control segment (ground monitors and control stations), and user segment (manpack, vehicular, airborne, and shipborne navigation sets). The network analysis program 'Advanced SOLVNET' was selected as the vehicle for performing the cost analysis of the Army user equipment Phase II effort. SOLVNET networks consist of (1) arcs, representing activities, and (2) nodes, representing the events (milestones) and logic of the project activity sequence. SOLVNET nodes consist of input and output rules. When the proper input rule conditions are realized, the node is said to be satisfied and its output arcs are initiated according to its output rule.
