讲座主要内容
Present bias, especially without self-awareness, causes significant loss of utility in operational decisions. This loss arises from poor task choice and procrastination. This work considers the effect of present bias in a simple scheduling system that requires decisions about project timing and sequencing. We design algorithms that enable optimization of revenue less cost under present bias for both naive and sophisticated (i.e., self-aware) decision makers. We describe managerial insights about the relative performance of time-consistent, naive, and sophisticated decision makers, and how to mitigate the effects of present bias. Both theoretical and computational results support these insights. [Hall and Liu, POM 32 (2023) 1743-1759.]. Additionally, project management is responsible for almost 30% of the world's economic activity, with an annual value of $27 trillion. We show that the traditional explanation for project lateness, i.e. Parkinson's Law, is insufficient and present bias is a better explanation. We therefore design and test an incentive scheme to mitigate the effect of present bias. [Shi, Hall and Cui, OR 71 (2023).]
