Abstract: 본 발명은 인터넷과 ARS(자동전화응답시스템)를 이용해 토목·건설용 철재(신품 또는 고철)를 판매, 구매 및 중개하는 방법에 관한 것이다. 기존의 토목·건설용 철재는 전국 수천 개의 철재 유통회사들과 제철·제강회사, 건설사들의 영업부서를 통해 판매, 구매할 물건들을 직접 거래하거나, 중개인(브로커)들을 통해 물품을 확보하는 영업방식을 고수해 왔다. 이 과정에서 매달 물품확보를 위해 많은 시간과 비용을 지불하는 소모적 영업이 반복되어 왔으나 필요한 물품을 적시에 확보하지 못하는 경우가 많았다. 
     본 발명은 이러한 문제를 해결하기 위해 물품(철재)을 판매자(500)와 구매자(600) 쌍방이 인터넷 웹 브라우저(300)나 ARS(100)를 이용해 판매·구매하고자 하는 물품의 상세 내역을 등록(10-1, 10-3)하고, 이를 자동검색하는 DB(데이터 베이스)엔진(200)에 의해 조건이 일치하는 판매·구매자의 연락처(전자메일 주소와 일반전화 또는 이동전화)로 즉시 자동 연락을 해서 (10-2, 10-4, 10-6, 10-8) 쌍방의 거래가 신속히 이루어지는 온라인 네트웍을 구축하는 것이다. 
     본 발명은 인터넷 웹 사이트를 제작하고, 웹 사이트 운영과 ARS 기판(board) 운영을 위한 프로그램 및 웹 사이트와 ARS 양자의 운영을 통제하는 프로그램 제작, DB 등의 소프트웨어 구축과 ARS 기판을 장착한 PC 서버(server), 서버용 전용선, ARS용 전화회선 등의 하드웨어 구축을 통해 구현한다. 
     본 발명을 통해 판매·구매희망자는 철재 확보를 위해 소모되는 시간과 비용을 최대한 줄이고 자신이 원하는 물품을 신속하게 확보할 수 있다. 
     또한 본 발명은 철재 판매·구매 뿐 아니라 조건에 맞는 물품 검색이 되었을 경우 신속한 상거래 성립을 위해 인터넷과 ARS로 등록된 자료를 즉시 일반 또는 이동전화로 자동 연락해 주는 네트웍을 필요로 하는 어떤 비즈니스 모델에도 응용할 수 있다.
