Empirical Operations Management
This is the field of operations management that applies empirical research methods. It involves collecting and analyzing empirical data (either collected from an industry or database) to gain insights into the various aspects of operational processes. Here, the aim is to develop a regression model to understand the relationships between different variables and make evidence-based decisions to improve operational performance. It can help bridge the gap between theory and practice by providing empirical evidence based on data from the real world.
Examples of Research Questions
During the COVID-19 Pandemic, is it better to diversify/concentrate a customer base to build supply chain resilience?
How do stock markets react to supply chain disruptions such as the COVID-19 lockdown?
Behavioral Operations Management
This is a subset of empirical operations management where the focus is on understanding and influencing the behavior of individuals and groups involved in operational processes. It considers the behavioral aspects of operations, including decision-making, motivation, teamwork and coordination. For example, we can mathematically model and predict how groups make decisions and interact within operational settings. If player A in a group faces inequality aversion (a preference to avoid the inequality in profits), we can write down his utility function as
using its own profit and its partner's profit. We can then test such a model in a specific operations setting using a behavioral lab study. Based on the findings, we can develop strategies to improve performance and decision-making processes.
Examples of Research Questions
How can we effectively divide tasks in the operational process?
When can we improve forecasting performance when forecasters rely on AI?
