Due to computer support access communication net design mode and the manner

摘要

PROBLEM TO BE SOLVED: To provide an access communication design system capable of automatically designing a less expensive access communication network by using existing equipment base on requirements under various restricting conditions. ;SOLUTION: A plurality of equipment are sorted into communication equipment and civil engineering equipment, wherein each equipment is provided with information indicating that the equipment is to be deleted before automatic design or its position is fixed and free capacity is utilized, and a designer is allowed to optionally defined as equipment layout candidate place so as to calculate access communication network constitution of a low equipment cost and necessary civil engineering equipment. Equipment information is read out at first (21), various parameters including the number of demands to be added this time, the cost of respective equipment and design plans (22), communication/ civil engineering equipment are edited if necessary (23), and it is specified whether or not each equipment is to be utilized for additional type automatic design (24). As to an equipment of which additional design mode is specified, its position is fixed and free capacity is utilized so as to reduce equipment cost to calculate an access communication network of a low equipment cost.;COPYRIGHT: (C)1999,JPO
