The system should make the best of all kinds of information sources around the enterprise, and meet the demand for agile production. This paper presents an implementation scheme of Integrated Equipment Maintenance Management Information System Based on Internet/Intranet and gives component division scheme of each tier. This scheme adopts a three-tiers mode of B/S (Browser/Server) and software programming module based on software reusing technology. This makes the system integrated and open, makes maintenance and updating convenient, and largely increases software safety and reusability.展开更多
