UCAV (unmanned combat aerial vehicle) preliminary design process graph.
The graph contains 14 preliminary design activities. Each phase consists of an initial activity to define design several disciplines-such as aerodynamics, propulsion, stability and control (S&C), distribute a design configuration (a design concept proposed to satisfy the DR&O). Then, requirements and objectives (DR&O), followed by a couple of activities to create and mechanical and electrical, weights, and performance - each evaluate the configuration from their own perspective.
The nodes contain a minimum, mean and max weight for both duration and cost, as well as an improvement curve value. The improvement curve determines the savings in work for each successive iteration of an activity. The edges contain a binary weight and rework probability and rework impact annotations.
When an activity is performed before all activities with edges to that activity has been succesfully executed, there is a rework probability that the activity needs to be redone, the impact then indicates the percentage that needs to be redone and the improvement curve decreases this in successive iterations.
