【摘要】 不稳定性制造环境的客观存在将不可避免地影响植根于生产系统之中的选配过程的顺利进行，进而对最终的选配结果产生一定的干扰，鉴于国内外对选配的不确定性研究的欠缺，本文旨在研究不确定制造环境下的机械产品选配方法：首先采用逆序的思维方式，以选配质量最优化、选配效率最大化和选配成本最小化等目标为起点建立选配不确定性产生机理的概念模型；接着从不确定性因素的根源着手建立一系列降低选配不确定性的策略与方法，这些都为下一阶段研究恰当的选配方法来达到选配质量最优化、效率最大化以及成本最小化的多目标选配做好前期保障工作；鉴于现行研究中对总装后产品质量稳定性的欠考虑，构建了基于质量损失函数的产品质量损失成本模型(P-QLC)。不仅兼顾了装配精度与质量稳定性要求，而且在此基础上构建的自动选配系统也可在一定范围内保证较高的装配效率和较低的选配成本；最后在不确定性策略的保障基础上给出了应用该方法解决一个机械产品的选配问题，以证明该方法的可行性与有效性。更多还原

【Abstract】 The external existence of uncertain manufacturing environment influences inevitably the smooth progress of assembly process and brings some disturbance or fluctuation on final result of selective assembly, as we know, there is a great deficiencies about the abroad and domestic research on uncertain selective assembly, so this paper expatiates on methods of selective assembly in the uncertain manufacturing environment: At first, the conceptual model about the causes leading to uncertain selective assembly was built by the beginning of several selective assembling targets such as optimization of product quality, maximum of assembling efficiency, minimum of assembling cost and so on, so all of these adopt the manner of converse thinking. Secondly, a series of strategies and methods for reducing uncertainty of selective assembly were built by the begin of the root about uncertain factors which make great effect on selective assembly, all of these strategies and methods are regarded as the effective prophase guaranteeing work for the next phase research on appropriate methods of selective assembly aiming at the optimization of product quality, the maximum of assembling efficiency and the minimum of assembling cost. Thirdly, because of great limitation of the quality stability about final-assembled product in current research, the product quality lost cost (P-QLC) model is built on the basis of Taguchi-quality-lose function which focuses on the optimization of selective assembly, this model can not only give attention to the requests of assembling precision and quality stability together, but also guarantee more precision demand of assembly and less cost of selective assembly by the auto-selective-assembling system which is based on above model. Finally, in order to prove this way’s efficiency and feasibility, an example is offered to resolve the selective assembly problem about a mechanical product by applying this way, which is based on the assurance of uncertainty strategies.更多还原
