The DITOPS Demo:
Move Requirement View
Loaded Move Requirements
The aircraft utilization views give us visual information about the resource utilization -- they basically show us capacity constraints. However, they provide little information about the move requirements. Most of the time constraints, like release and due date, are associated to the move requirement descriptions.
The order window provides the visualization of time constraints associated with the move requirements. Similar to the resource window, the order window has the current time and the time line in the first line. The left column buttons are the move requirement identifications. The rectangles left and right edges represent movement release and due dates respectively. The triangle inside the rectangle is the earliest arrival date -- the tip of the triangle is the earliest arrival date. The black I-beams represent the interval of time in which the movement has been actually scheduled. If the right edge of the I-beam falls outside the dark rectangle, the movement is late. As we can see in the center of the order view, several of the movements are late.
The selection mechanism also works on the order window. We have the ability of selecting a move requirement and inspecting or manipulating it. In the example, we selected the second move requirement from top and created a textual description of it.
Each line in this view represents a move requirement. The beginning of the blue rectangle is the release date of the request; the end of the blue rectangle is the due-date specified for the request. The tip of the green triangle represent the EAD or earliest arrival time; the black line represent the time interval to
scheduled to complete the entire movement. We can identify the movements that are late by lookin at the end of the black line: if it falls outside the blue rectangle, the movement is late. Notice that to complete the same movement, more than one trip can be required. The lateness of a move requirement would be equal to the lateness of the latest scheduled operation. The visualization of the movement and its constituents trips is provided in the expanded view.
