以正好满足产品需求为约束条件的车间最优生产计划 总被引:3,自引:1,他引:2
研究以正好满足产品需求为约束条件的预选性自动化车间(FAW)伯最优生产计划问题,首先根据实际需要建立车间生产计划的含需求约束的非线性规划模型,然后为求解方便通过引进约束将其转化成线性规划模型,由于这种模型对于一般车间来讲其规模已经很大,很难在微机上用单纯形法在可接受的时间内获得其最优解,为此,提出分别用卡马卡算法和基于卡马卡算法的关联预测法来求解车间最优生产计划问题,并编制了相应软件,最后,通过算例研究,比较了卡马卡算法,基于卡马卡算法的关联预测法和Matlab中的线性规划法,结果表明所提方法非常适合将ERP/MRPII下达给FAW的中期计划最优分解成由FAW中各FMS执行的短期计划。 相似文献

The paper is about negotiating with issues that discourage innovation. The subject is environmental deterioration, with concern directed at the impediments that keep it from being innovatively resolved. The paper is organized around three issues. (1) The dominant model of environmental concern, called environmental protection, is managed predominantly via command and control approaches. (2) Command and control, by relying on analytical segmentation to subdivide the problem into digestible bits and using formal legislation to direct it, are not up to emerging challenges in the area. (3) More robust models are available but difficult to experiment with due to impediments that discourage change. These impediments are seen in ideals associated with protection, prevention, recycling, and sustainability that tend to do more to sustain harmful practices than to seek beneficial alternatives. Being able to appreciate the underlying restrictions of entropy could help stimulate a more innovative agenda. These issues are tested via a project funded by the EPA entitled ENERGY STAR Homes. 相似文献
