2 abnormal fluctuation of temperature of reactor, in the metaphase of reaction # 3 abnormal lower stirring power in the early stage of reaction, bring down various flow rates and various temperatures # 4 abnormal lower temperate of the water inlet in the early stage of reaction,

The data of 50 normal batches are selected from the examples of the practical process as a training dataset. There are other 50 batches sent to the history library Ω, so the number of

From Fig.8 we can observe clearly the asynchronous chosen batches from temperature of the reactor (variable 1). There are 10 batches (#1~#10) taken as test data from the batch process in the plant. Some problems of these batches are listed in Table 2 in the polymerization of batch process, one tries to discriminate the abnormal of them with two statistics of SPE and T2 of MPCA, or SPE and I2 of MICA, and then find whose variables

cause the fluctuation of flow rate of baffle water and lower pressure
