| Based on the module and commonality of the product family, the problem of mixed streamline assembly balance and sequence, which faces to the product family assembling, is studied. On the basis of the cluster analysis to the product family assembling process, the organization form of mixed-mode assembly line which faces to the product family is Proposed; in view of organization form characteristic of mixed-mode assembly line which faces to the product family, its balance design method and the model is proposed; the sequencing model is built on the balance foundation of mixed model assembly line; The application of the method in this text with a case is stated finally. This article is about a content which has important social and economic efficiency.Firstly, aiming at the modular constitution characteristic of product family and product platform, analyzing the similarity and the difference of the module by clustering arithmetic, it propose the organization form of mixed-model assembly line which faces to the product family. to maximize the production efficiency, The assembly line design must conform to the product structure. Therefore, it must fully know and the use the modulation constitution characteristic of product family, and manifest to the user response thought in the assembly process by mapping analysis among the product race, the module and the craft.According to the organization form of mixed-model assembly line which faces to the product family, its balance influence factor is analyzed. It Points out that both load balanced condition between each modular assembly unit and reducing unused time on each modular assembly unit to achieve the balanced goal of both load balanced and the most superior unused time. Its balance question mathematical model has been established on this foundation. its balance question mathematical model has been established on this foundation, and the rhythm time of each modular assembly unit is determined finally. Regarding the balance result, the appraisal target and the assessment method is given out correspondingly in the article.After the mixed-model assembly line achieved the balance, the sequencing problem is a key which whether the decision assembles effectively carries on. it built sequencing model by the goal that balance the module consumption speed of each modular assembly unit on the mixed-model assembly line. mixed-model assembly line... |
