We then want to find a method for making decisions. There are at least 45 words in the English language that are equivalent to "method for making a decision," but the one we have settled on is policy. The term policy is very familiar to fields such as Markov decision processes and reinforcement learning, but with a much narrower interpretation than we will use. Other fields do not use the term at all. Designing effective policies will be the focus of most of this book. Even more subtle is identifying the different sources of uncertainty. It can be hard enough trying to identify potential decisions, but thinking about all the random events that might affect whatever it is that you are managing, whether it is reducing disease, managing inventories, or making investments, can seem like a hopeless challenge"--
