New Approach to Integrated Evaluation of the Overall Level of Execution of a Technology and Product Quality on the Basis of Statistical Methods
The parameters currently used to evaluate the execution of production processes and product quality in the metallurgical industry are analyzed. A new approach is proposed to integrated evaluation and prediction of the performance of a factory with allowance for product quality, the sophistication of the technology, and order completion. A new method has also been developed for controlling production processes. This method entails calculation of the index “Probability of order completion with deviations from the specifications.” Among the advantages of the method is the possibility of predicting deviations in product quality when there are deviations from the specified process parameters. Another advantage is that the method makes it possible to correct problems in the process of completing customers’ orders.
