Description:
The economic benefit of "good" data in any production environment is largely conditional on the plant’s ability to effectively forecast, plan, schedule, control and execute the production cycle. Good data alone will not capture the maximum achievable benefit given that bad exogenous1 information translates into bad endogenous information and therefore may be considered as a necessary condition only for optimal economic prosperity in the value-chain. That said, how do we obtain good data to at least satisfy this necessary condition when we must consider the entire production facility as one interconnected economic system? Accurate process measurements are certainly a requirement yet we cannot always guarantee their continuous and sustained accuracy given the vast number of these instruments available in the field. One popular approach is to perform a comprehensive mass reconciliation around the entire boundary limits and internals of the manufacturing or autofacturing process in order to cross-check the production measurements using the law of conservation of mass.
