REPO

and must be exited using an

     END_REPO

command. At this menu level, several commands are available to specify preferences for performing the repositioning, display the selected values, and perform the repositioning. These commands are:

     DO_REPO

     WEIGHT_CONN, WT, :SC(1), :SC(2), ..., :SC(n)

     BOUNDS_CONN, UB, LB, :SC(1), :SC(2), ..., :SC(n)

     SELECT_CONN, :SC(1), :SC(2), ..., :SC(n)

     DESIRE_VALUE, DES, :SC(1), :SC(2), ..., :SC(n)

     TUG_DCHANGE, WFMUL, WDMUL, :TS(1), :TS(2), ..., :TS(n)

     SHOW_SYS

The DO_REPO command instructs MOSES to find new line lengths and tug forces so that the system will be in equilibrium at the current position, subject to the controls specified with the other commands. This problem will not always have a solution as specified and it is up to the user to check that he finds the results suitable for his purpose.

This command changes only those connectors selected by the latest SELECT_CONN command, and will keep the tensions (tug forces) between the upper and lower bounds as specified for each connector using BOUNDS_CONN. Here, UB is the upper bound, while LB is the lower bound, both in bforce units. The equilibrium solution keeps the force in each connector as close as possible to the desired value, DES (bforce), defined with DESIRE_VALUE. The command WEIGHT_CONN is used to specify the relative desirability of changing a given connector. With this command, WT is the relative weight factor to be used for the specified connectors. For all these commands, :SC(n) and :TS(n) refers to a selection criteria containing connector names, or can refer to the connector name itself. The SHOW_SYS command will produce a report showing the selection status, current force, desired force, upper and lower bounds, and the weight value for each connector.

Normally, MOSES will change force in tugs instead of changing their direction. The command TUG_DCHANGE allows for a tug to change direction as well. Here, WFMUL and WDMUL are the relative desirability factors for changing force and direction, respectively.
