The Operators Tab Graphical Representation

The Operators Tab Graphical Representation

This representation shows, for the selected workstation, as many task schedule bars as there are operators assigned to the workstation. Each of the task schedule bars represents the tasks performed by the associated operator, with the time going from bottom up. Each task (operation) is represented by a segment. An operation requiring multiple operators is represented by that many time segments (one per operator) joined with a yellow line (for instance the Operation 82 in the above graph). A precedence constraint between operations within the workstation is represented by a red arrow going from the predecessor to the successor (bottom up). Below each operator task schedule bar is the id of the operator and the total length of his schedule, i.e. the time unit when all his tasks are finished.

in some cases, the constraints make it impossible to assign a contiguous set of tasks to an operator. In that case, the operator may be experiencing idle time, which is simply represented by a gap in his schedule (For instance the green part between operation 223 and 184 in the above graph).
the cycle time of the operator (the maximum amount of time he can spend on the line) is represented by a green dashed part at the top of the task schedule. As long as the top of the green part is visible (i.e. is not obscured by a task), the operator finishes all his tasks on time. In that case, the indication at the bottom of the bar is shown in black, otherwise it is shown in red to indicate overflow of the operator cycle time.
