A Web-Based Visual Planning and Scheduling System for Steelmaking and Continuous Casting

This paper presents a B/S architecture system for automatic planning and visualized result scheduling in the context of steelmaking and continuous casting workshop in iron and steel enterprise. The system under study is based on a real world industrial application. The automatic planning module which adopts the heuristic algorithm is characterized by several constrains such as manufacture continuity, production goods supply, changeable technological route, equipment capability, dynamic job processing time. This module is designed to help planner making plan automatically with aims of averaging productivity, minimizing the total stop time during the production and increasing the practicability of the result. The result scheduling module supplies the function of visual plan inquiry and adjustment with the skills of AJAX and VML, which is conducted to make the planning real-time and easily. Commonality is fully considered during the design, so this system applies to different iron and steel enterprises.
