Multivariate Statistical Analysis Finds the Bad Actors in Out-of-Spec Batches Case StudyCHALLENGE This polymers producer had been regularly producing out-of-spec batches and could not determine the cause. SOLUTION Aspen ProMV desktop batch model was developed to identify the bad actors in the off- spec batches. BENEFITS This pilot project provided proof that Aspen ProMV can understand and resolve production problems faster to limit the losses. Aspen ProMV was able to: • Highlight the few process variables (from a total of around 80) that correlate closely to quality • Show how the company’s batch operating procedures were affecting batch quality Aspen ProMVTM found the three variables (of around 80) that correlated to quality.Off-Spec Batches Lead to Revenue Loss A large producer
