It follows that in S12, xEMS (i) determines whether j=N.
In the case of not j=N, (S12, "No"), i.e. existence have the son bigger than i
In the case of the xEMS of System Number, in S13, xEMS (i) calculates and i is added 1
Value, the value that calculates is substituted into new i, makes process transfer to S15.
In the case of being j=N (S12, "Yes"), the most do not exist there is the son bigger than i
In the case of the xEMS of System Number, in S14, xEMS (i) substitutes into i by 1, makes process
Transfer to S15.
In S15, xEMS (i) judges that xEMS (j) forms association with other xEMS the most
Make.Herein, xEMS (i) obtains the management data of xEMS (j) from data fields 10, at xEMS
J the management data of () include the data of other xEMS in the case of, it is determined that for xEMS (j)
Form with other xEMS and cooperated.
