In this paper, we analyze the impact of two forms of commonly used threshold-based incentive schemes on the observed sales variability. The first form of the incentive comprises an additional marginal payment on crossing a specified sales threshold and the second form of the incentive scheme...

Lean global supply chains have exhibited considerable improvements in inventory levels, lead times, and service levels in recent decades. Still, global disruptions such as pandemics have exposed the hidden vulnerabilities of these supply chains. This study extends the previous literature by...

We consider a two-echelon supply chain with a manufacturer supplying to multiple downstream retailers engaged in differentiated Cournot competition. Each retailer has private information about uncertain demand. The manufacturer is the Stackelberg leader who sets the contract terms with the...

Propagation of disruptions across networks is a feature of the modern economy. An example of disruption propagation is in airline networks where disruptions, like hurricanes, cause delays which propagate through the network. Modeling the propagation of delays in airlines is difficult due to the...

Early infant diagnosis (EID) programs in many resource-limited settings are aimed at diagnosing infants born to HIV positive mothers. Due to the complexity of the diagnostic technology, EID programs are often highly centralized with few laboratories testing blood samples from a large network of...

This work bridges the gap between the discrete and the continuous fractional programming literature by solving a class of 0-1 fractional programs as continuous fractional programs. Specifically, we consider 0-1 linear fractional programs under cardinality-type constraints and provide a...
