The
value added is an optional attribute that can be
specified on each operation of the system. This value is shown for each
operation, and the average value of all operations is shown for the system.
Value added of an operation is an estimate of
how much time that the operation is used for assembly. It is expressed as a
percentage. If no time of the operation is spent on assembly, the
value added can be specified as 0%.
Value added can be used on an operation that
has its time mode defined as Estimated time or Analyzed time. For
value added based on Estimated time, the value
is defined in the operation's
Properties dialog box. For
value added based on Analyzed time, the value is
defined using
Edit Time Analysis. See the
Time-Motion Study
User's Guide for more information.
Sometimes operations have time modes defined as Simulated time or Work
instruction. In this case, the
value added is the percentage defined in
Value Added Ratio on Estimated Time in the
Properties dialog box.
Note:
This information is only displayed in the Gantt chart when the Display value
added ration on system option is selected in
.
You can display a value added categories bar on top of the system cycle
bar. The value added categories are defined on the time
analysis of an operation. You can specify the color of each category in
(for example, green for value added, red for
nonvalue added, and so on). The total value for each
category is computed for all the operations in the system.

This information is
only displayed when the Display value added categories from Time
Analysis on system option is selected in the
