返工率

该方法与传统造船模式相比，可大大降低管系设计与布置中的返工率和管材浪费。

In contrast to traditional shipbuilding mode , this method can sharply lower the rate of repetition and material wasting in pipe design and arrangement period .

通过该方法来模拟造船过程，可以随时对各设备进行干涉检查和装配监测，因而能大大降低返工率，提高船舶设计及区域化建造水平。

Employing this method to simulate shipbuilding procedure can perform interference checking between devices and monitor assembly at any time . Thus it can greatly lower repetition rate and improve the efficiency of design and construction level of block shipbuilding .

而虚拟企业的组织沟通效率却好于传统企业，虚拟企业的组织沟通的时效性好，沟通返工率低，沟通的信息有用比高。

But the efficiency of organization communication of the virtual enterprise is better than the traditional enterprise as the organization communication of the virtual enterprise is good in aging , low in communication reworking rate and high in communication information usefulness rate .

在返工成本率指标上，竞争性投标总价合同与单价合同在0.05的显著性水平上存在显著性差异。

At the significance level of 0.05 , the mean values of the rate of cost overran is significantly different between lump sum through competitive bidding and unit price .
