MOVABLE PLATFORM FENCE INSTALLATION CONTRACT SUPPORTING SYSTEM

摘要

PROBLEM TO BE SOLVED: To propose a reduction in initial cost for introducing and installing movable platform fences to promote the introduction of movable platform fences by a railroad company.

SOLUTION: This is a supporting system for reducing an initial cost to be imposed on a railroad company for introducing and installing movable platform fences by combining movable platform fence delivering-and-installing business with advertisement income business using the advertisement-installing spaces of movable platform fences to promote an installation contract of movable platform fences. This system computes an initial introduction and installation cost required for installing movable platform fences, examines an advertisement publication rate (an advertisement income) and computes the number-of-month (NM) required for recovering the reduced value (BG) by the advertisement publication rate and presents the results of the computation and examination.
