INTECH JULY/AUGUST 2019 25 FACTORY AUTOMATION could comprise a series of digital twins based on phys- iochemistry, such as an in tegrated process/energy/reli- ability digital twin, operator training simulation twins, and dynamic real-time optimization twins (for process/utility systems). l Integrated control and safety. This could constitute a digi- tal copy of the live plant and its automation algorithms through the "twin" function of an integrated control and safety system, thereby allowing engineers to conduct fun- damental process control tests at an engineering worksta- tion, as well as any proposed adjustments, before they are applied on the live plant. l Instruments and devices. This could constitute highly in telligent devices, such as pumps, flowmeters, and trans- mitters, or chemical analyzers that provide total insight into their ongoing performance as well as an ability to adapt to changing duty requirements throughout the mea- surement device life cycle. l Operator processes. This could comprise a copy of opera- tor work processes to be executed, which could be tracked and manipulated in real time. The digital twin promises to be a fantastic tool for strategy execution by ensuring field and line employees have the in- formation they need to understand the bottom-line impact of their day-to-day choices. Strategy execution is also sup- ported because a digital twin can facilitate information flows across organizational boundaries and minimize second- guessing of decisions. A key challenge of the digital twin is that it needs to exist within a strong governance framework. This includes well- defined business processes, along with clarity about the de cision rights and actions for which people are responsible. One area that needs to be considered is the necessary guidance from subject-matter experts and their associated analytical insights. These can be third parties, but often these experts are in-house yet remote from the operational loca- tion. Currently, these insights are obtained when there is a problem or when structured inputs are sent on a regular ba- sis, such as in a weekly meeting or a quarterly service review. As the energy and chemical industries move away from buying inputs to buying outcomes-as-a-service (XaaS) at both point and holistic solution levels, the digital twin will become increasingly important (figure 5). The digital twin serves as the single basis from which all outcomes are de rived. The regularity of the inputs has been replaced with a digital twin predicting when service is optimal, consider- ing current and future operation, and providing the time and best path for all stakeholders as decisions are made. This brings agility and convergence in understanding and action YEARS www.buerklin.com 1.5+ million articles from 500+ renowned manufacturers Our services: n 75,000+ articles in stock in Munich, Germany n 500,000+ additional articles readily available n Delivery promise: Same day shipping for all orders received by 6pm n Online Shop: buerklin.com n Industry-focus line cards of well-known and reliable manufacturers n eProcurement solutions: OCI, API, electronic catalogs, EDI n Large teams of multilingual inside sales and field sales in Germany n Sales representatives in Italy, France, United Kingdom, Ireland, Scandinavia, Eastern Europe, Brazil and the Middle East A key challenge of the digital twin is that it needs to exist within a strong governance framework.
