A contribution to the optimal numbering of a ring structure

Abstract

An optimal element numbering of a pipeline system containing rings is considered. In order to minimize the front width two possible cases of ring structure are analysed and solved in different manners. An example is shown of a typical one having both types of rings. By applying the automatic procedure for element numbering, the front width can be reduced by approximately 40%. The algorithm and FORTRAN 77 programme are presented, as well as input and output data for the example.
