Requirements volatility: Changing requirements that impact delivery schedules and increase software rework and cost. 需求变化:变更需求将会影响交付的时间表并增加软件返工和成本。
Adverse trends would indicate inadequate design and a need for rework, with negative impact on technical, cost, and schedule baselines& and potentially on the system's operational effectiveness. 有害趋势可以表明不适当的设计和重新工作的需求,对技术、成本,以及进度基线都有负面影响&还可能对系统的操作有效性有潜在影响。
By minimizing rework, slow run-ning equipment and downtime, maximum value is added at the minimum cost. 在使减到最小的重做、慢连续设备和停工期以前,最大值增加在极小的费用。
The statistical analysis of results also indicates that construction-contract affects quality cost most in all contract patterns, and the rework cost is largest in CM model, and each construction process affects the quality cost with same magnitude. 调查结果统计分析还揭示了各种承包方式中,施工总承包对质量成本影响最大,代建制模式下返工成本最高,而建设各阶段对质量成本的影响无显著性差异。
Isolated design and manufacturing will lead to design rework, manufacturing difficulty, low productivity and high cost. 在传统生产模式中,设计与制造(或工艺)的脱节造成了设计返工多、加工难、效率低、成本高的弊病。
The tolerance design in conceptual-structure design stage can identify the product problem, lessen the design rework, shorten the design period and reduce the cost. 首次提出了基于同步公差设计的概念结构设计优化理论,其本质是自顶向下和分解重构的设计思想在公差设计中的体现。
The effects of the shortage cost, rework cost and the percentage of the defective items on the optimal production policy are illustrated by numerical examples. 最后结合算例验证了所提出的模型,并分析了缺货费用、重修费用和缺陷产品比例对最优生产策略的影响。
