1. From the distribution network shown in Figure 3, form Table 3.

4. Similarly, increase the BN, and read the RE of BN. Then, check for the appearance of this RE in the SE row. If it appears one time, then fill these RE and BN values as the present row and present column elements of the variables BNM and BRNM. Then increase the column number by one and repeat step 4. If it does not appears or appears more than one time in the SE row, then fill the corresponding RE and BN values as present row and present column elements. Then identify this row as a section. Then increase the row number by one and set the column number to one and repeat the step 4.

The above steps are repeated until the BN value reaches the last branch number. At the end, the BNM and BRNM are obtained as follows:
