Performance evaluation of multi-input–single-output (MISO) production process using transfer function and fuzzy logic: Case study of a brewery

Abstract

This work reports an improved and novel new method of evaluating the performance of multi input single output (MISO) processes, as exemplified by a brewery. This new method involves the combination of transfer function modeling and fuzzy logic and was used in evaluating the six years performance of a brewery. Of the six years, the period 2010–2011 with a performance rating λ of 0.810 which corresponds to the linguistic variable ‘Good’ recorded the best performance while the period 2008–2009 with a performance rating λ of 0.381 which corresponds to the linguistic variable ‘Fair’ recorded the worst performance. The result of this study is expected to open new ways of improving maintenance effectiveness, utilization of raw materials and efficiency of multi input single output (MISO) production processes.
