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...

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...

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...

The multi-objective flight instructor scheduling problem is an optimization problem that schedules instructors to teach a set of pilot training events. The objectives of the problem are to minimize labor cost, maximize workload consistency and maximize flight instructor satisfaction of their...

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...
