CSDT - Crew Station Design Tool

CSDT

Alion's Crew Station Design Tool (CSDT) allows designers to visualize and optimize their choices of controls and displays, and the position of those elements in a workstation.

CSDT

CSDT automatically determines the optimum arrangement of controls and displays based upon sound human engineering and ergonomics principles. In order to accomplish this, CSDT uses the task network modeling software Micro Saint® Sharp and communicates with the human figure (anthropometric) software Tecnomatix Jack® from Siemens PLM Software, Inc.

Using the results of a task analysis as its foundation, CSDT helps designers select the most appropriate control for a task and builds a task network model of the activities performed in their desired workstation. Once executed, the task network model identifies operator-task conflicts and provides frequency-of-use data for each control and display.

CSDT uses this data to place the selected controls and displays in Micro Saint Sharp’s Animator3D. Finally, the suggested arrangement and the data acquired from the task network model are used to generate and execute a three-dimensional human figure model in Jack. Jack simulates the physical behavior of humans interacting in the workstation and allows designers to visualize the feasibility of certain tasks (i.e., can a human see and actuate a control within the specified environment).

When the designer has finished viewing the Jack model, he or she can return to any part of CSDT to make adjustments in their design.
