9870865Nembhard This GOALI Faculty in Industry award funds the development of a simulation model of continuous manufacturing systems during the startup phase. Engineering process control procedures based on first-order and second-order dynamic equations will be used in the model to make adjustments to the system. A statistical process control procedure based on autocorrelation will be used in the model to monitor the system. The developed simulation model will characterize the dynamic process and the noise process that leads to out-of-specification product output associated with a startup. This research investigation will take place in partnership with a leading textile manufacturer. The simulation model will be designed and validated in the context of the finishing operations for textile manufacturing. Experiments involving new policies to reduce the scrap for the startup phase will be conducted using the simulation model. If successful, the results of this research will lead to the establishment of new operational methods for the startup phase. In practical terms, one expected outcome of this research is a reduction in the amount of waste carpet associated with the startup. This research also has general implications for other continuous manufacturing systems -- such as food and beverage, chemicals and paint, and pharmaceuticals -- as the number of startups continues to increase with the shift to make-to-order production to meet customer demands. Out of this broader, long-range concern, we plan to identify related projects and continue the industry involvement fostered by this partnership.

小行星9870865 该GOALI工业学院奖资助在启动阶段开发连续制造系统的仿真模型。基于一阶和二阶动态方程的工程过程控制程序将用于模型中，以对系统进行调整。将在模型中使用基于自相关的统计过程控制程序来监测系统。所开发的仿真模型将表征动态过程和噪声过程，导致与启动相关的超出规格的产品输出。这项研究调查将与一家领先的纺织品制造商合作进行。仿真模型将在纺织制造的整理操作的背景下进行设计和验证。将使用模拟模型进行实验，涉及新的政策，以减少启动阶段的废料。 如果成功，这项研究的结果将导致建立新的业务方法的启动阶段。 实际上，这项研究的一个预期结果是减少与初创公司相关的废地毯数量。这项研究对其他连续制造系统也有普遍的影响-如食品和饮料，化学品和油漆，以及制药-随着转向按订单生产以满足客户需求，创业公司的数量不断增加。出于这一更广泛、更长远的关注，我们计划确定相关项目，并继续推动这一伙伴关系所促进的行业参与。
