By experimental data analysis, the randomchange of the reciprocal induction time as well as the induction time is in conformity to logarithmic normal distribution.
实验数据分析表明,诱导时间的倒数的随机变化规律服从对数正态分布。同样,诱导时间亦服从对数正态分布。

Based on the improving of MRP to adapt to job shop, it also add the supporting to the changed plan, which corresponding to the varied require caused by the order form's randomchange.
Therefore, the concentration of development and decentralized energy use, as well as a continuous power supply and load a randomchange, it restricted the power system structure and operation.
