3、流程，让流程在企业的运转中发挥到最佳。论文在吸收国内外相关研究成果的基础上，在对我国多品种小批量制造企业生产管理和生产管理流程现状进行分析后，引入流程优化(Process optimization)、精益流程(Lean process)和精益生产(Lean production)的思想，提出了研究多品种小批量制造企业生产管理流程精益化的课题。论文首先分析研究了多品种小批量制造企业的生产环境和生产管理模式，并且对现行模式下生产管理流程存在的问题和利弊进行了分析，结合精益流程管理，提出了生产管理流程精益化。其次论文详细分析了流程精益化的特点和要求，在此基础上从流程精益化的思路、方法、构架和实施步骤
4、等方面，详细阐述了生产管理流程精益化方案。论文最终将以上研究方案运用到 X 公司流程管理中，从组织结构优化出发，对企业核心生产管理流程进行了规划和实施，为柔性生产管理模式的建立奠定了基础。论文的研究内容在 X 公司得到了实施应用，取得了较好的应用效果。本文的研究成果为其它多品种小批量制造企业实施精益流程管理提供了参考和借鉴。关键词：多品种，小批量，流程优化，精益流程，精益生产II重庆大学硕士学位论文中文摘要ABSTRACTThere are increasingly uncertainties in manufacturing enterprise due to the trend ofglo
