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...

Motivated by the recent success of integer programming based procedures for computing discrete forecast horizons, we consider two-product variants of the classical dynamic lot-size model. In the first variant, we impose a warehouse capacity constraint on the total ending inventory of the two...

We present structural and computational investigations of a new class of weak forecast horizons - minimal forecast horizons under the assumption that future demands are integer multiples of a given positive real number - for a specific class of dynamic lot-size (DLS) problems. Apart from being...

We develop inventory control strategies for a supplier who is selling a product to a group of human newsvendors. Recent research in newsvendor experiments using human subjects revealed significant behavioral tendencies in the decision making processes of human newsvendors. If the supplier would...

Storage assets are critical for temporal trading of commodities under volatile prices. State-of-the-art methods for managing storage such as the reoptimization heuristic (RH), which are part of commercial software, approximate a Markov decision process (MDP) assuming full information regarding...

We evaluate the impact of bundling on firms' product and pricing strategies by developing and solving a multi-stage game theoretic model to represent strategic interactions between two competing firms. Each firm is able to produce two homogeneous products and can opt to bundle them together,...

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...

This study considers a two-mode production system that allows the supply chain to utilize a fast reactive production with improved demand information before the selling season. However, the reactive production quantity is limited by the required preprocessing decision before the demand...

Service providers, in the presence of congestion and heterogeneity of customer waiting costs, often introduce a fee-based premier option using which the customers self-segment themselves. Examples of this practice are found in health care (concierge medicine), amusement parks, government...
