基于约束理论的IT制造业设备管理问题研究——以A企业为例

1、基于约束理论的IT制造业设备管理问题研究以A企业为例摘 要进入21世纪，科技飞速发展，近年来，IT行业的产品迭代速度更是迅猛，然而在产品线上的设备寿命却在不断的延续，面对复杂并且不断更换的产品线，如何更好的管理每条产品线上的各个设备以及如何提高每条产品线上设备的利用率成为当前各个互联网企业管理者研究的重点课题之一。当前我国的制造业面临着严峻的挑战，企业为保证自身在激烈的市场竞争中获得有利地位求得生存，不仅仅要提升自身的核心竞争力，还需要加强企业设备的管理，提升设备综合效率（Overall Equipment Effectiveness，OEE），这就体现在设备订购数量，维修成本以及设备有效开动率等各项指标的衡量上。OEE方法简单且实用，能有效监测和改进生产工艺，提高生产效率，已广泛应用于西方国家的制造业。首先，文章在前人的研究基础上，分析了约束理论在制造业中的重要作用，回顾了国内外设备管理的综合现状，并根据A 工厂的实际状况分析了设备的预订和后期管理。本课题研究是在互联网巨头B 公司要A 工厂为其提升产能的背景下产生。在约束理论的指导下，结合OEE的方法，了解平面抛光车间的问题，利用先

2、进技术指南来改进，提高设备综合效率，避免大笔资金购买新设备，从而提高生产能力，降低单位生产成本，改善产业链中间的竞争。基于对约束理论的理解，本文描述了综合设备能力在设备管理过程中的重要地位，并通过综合设备效率计算方法计算和分析了A工厂的不同生产过程。鉴于公司资源有限，根据约束理论，对整个生产链中设备覆盖的扩展进行了深入的分析和研究，并对抛光设备的设备和结构，过程控制和自动化控制等方面进行了改进。影响生产的主要问题已经取得了很好的改进。关键词：约束理论，设备管理，设备综合效率，平面抛光IIIRESEARCH ON IT MANUFACTURING EQUIPMENT MANAGEMENT BASED ON CONSTRAINT THEORY- TAKE ENTERPRISE A AS AN EXAMPLEABSTRACTEntering the 21st century, the rapid development of science and technology, in recent years, the IT industry products iteration speed is

3、 rapid, but in the product line of equipment but is a continuation of life, in the face of complex and constantly changing product line, how to better management of each product line equipment and how to improve the utilization rate of each product line equipment become the focus of the current Internet enterprise management research topic. Current our countrys manufacturing industry is facing serious challenges, enterprise in order to ensure their position in the fierce market competition for s

4、urvival, not just to improve their own core competitiveness, also need to strengthen the enterprise Equipment management, improve Equipment comprehensive efficiency (Overall Equipment Effectiveness, OEE), it is embodied in the Equipment order quantities, the maintenance cost and Equipment effectively to start the rate the indicators to measure. The OEE method is simple and practical. It can effectively monitor and improve the production process and improve the production efficiency. It has been
