초록 Process measurements contain random and gross errors and the size estimation of gross errors is required for production accounting. Mixed integer programming technique had been applied to identify and estimate the gross errors simultaneously. However, the compensate model based on mixed integer programming used all measured variables or spanning tree as gross error candidates. This makes gross error estimation problem combinatorial or computationally expensive. Mixed integer programming with test statistics is proposed for computationally inexpensive gross error identification/estimation. The gross error candidates are identified by measurement test and the set of gross error candidates are formulated as integer variables to confirm and estimate the size of gross errors in mixed integer programming. The proposed method is applied to the iron and steel making plant and the results are compared with the previous methods.
