Application of workflow technology for workshop scheduling

This paper attempts to solve the complexity of scheduling problems and meet the requirement of the ever-changing manufacturing environment. In this paper, a new Workflow-Based Scheduling System (WBSS) is proposed. The integration of Workflow Management System (WfMS) and rule-based scheduler provides us an effective way of generating a task-sheet according to the states of system and the scheduled objects. First, the definition of workflow model for scheduling is proposed, and following are the architecture and mechanism of the proposed WBSS. At last, an application is given to show how the established system works.

烟用丝束计量系统的研制

针对滤棒生产过程中,丝束的使用管理缺乏科学性、时效性等问题,研制了一套烟用丝束计量系统。系统通过设计超低台面精密电子秤,实时采集丝束箱质量信息;利用智能滤棒产量信号接收器累计滤棒数量;将丝束质量和滤棒产量传送至现场显示记录终端,计算并存储丝束出棒率及滤棒平均质量等各工艺参数;最后,利用Zig Bee无线传输技术将实时采集和处理的生产信息发送至集中管控计算机;同时,集中管控计算机也可以向车间显示记录终端发送各种生产指令。实验结果表明,该系统实时性好,可靠性高,使用方便,具有很高的推广价值。
