In this paper, we use integer programming (IP) to compute minimal forecast horizons for the classical dynamic lot-sizing problem (DLS). As a solution approach for computing forecast horizons, integer programming has been largely ignored by the research community. It is our belief that the...

Omnichannel firms regularly share information between their multiple channels (e.g., online vs. physical store), i.e., horizontal information sharing, to improve their operational and financial performance. As information often tends to be error-prone -- when it is collected, transmitted, or...

Anchoring and Insufficient Adjustment (AIA) bias has been observed in many newsvendor experiments, although a mathematical explanation for this behavior has previously eluded researchers. We show that risk aversion coupled with an implicit shortage cost, both of which are well-known components...

Many firms use ranking systems for the employee performance evaluation process, where they reward with higher wages to top performers and lower wages to low performers. However, in some firms, payoffs of an employee depend on the final outcomes of the assigned tasks and not on the relative...

Limited information about the demand for some of the resources needed to produce goods and services (e.g., incomplete and imperfect bills of materials) forces firms to use heuristics when planning resource capacity. We examine the performance of five heuristics: two drawn from practice, two that...
