Digitization offers significant opportunities for the formulated product industry to transform the way it works and develop new methods of business. R&D is one area of operation that is challenging to take advantage of these technologies due to its high level of domain specialisation and creativity but the benefits could be significant. Recent developments of base level technologies such as artificial intelligence (AI)/machine learning (ML), robotics and high performance computing (HPC), to name a few, present disruptive and transformative technologies which could offer new insights, discovery methods and enhanced chemical control when combined in a digital ecosystem of connectivity, distributive services and decentralisation. At the fundamental level, research in these technologies has shown that new physical and chemical insights can be gained, which in turn can augment experimental R&D approaches through physics-based chemical simulation, data driven models and hybrid approaches. In all of these cases, high quality data is required to build and validate models in addition to the skills and expertise to exploit such methods. In this article we give an overview of some of the digital technology demonstrators we have developed for formulated product R&D. We discuss the challenges in building and deploying these demonstrators.<br>

Chapter 9 turns to further epistemic barriers for decision makers: the problems of (nonmoral) ignorance and (nonmoral) uncertainty. The concepts of “ignorance” and “uncertainty” are elucidated, the problem of uncertainty is defined, and it is argued that the problem of ignorance should be treated as a special case of the problem of uncertainty. The three salient attempts to solve the problem are the Pragmatic, Austere, and Hybrid approaches. Combined solutions to the problem of error and the problem of uncertainty are explored, and it is argued that the only feasible approaches marry the Austere Response to the problem of error with the Hybrid Response to the problem of uncertainty in a two-tier system. The top-tier code provides the correct theoretical account of right and wrong, while the lower-tier rules provide associated decision-guides. Consistency requires that different normative terms be used by the top-tier rules and by the lower-tier rules.
