In this paper, a dispatching rule called the Weight Biased Modified RRrule is developed that minimizes the mean tardiness of weighted jobs in an m-machine job shop, i.e. Jm|ri,recrc|∑iTik where Tik denotes the tardiness of those jobs with weight greater than a specified threshold level k. It...

In this paper, a binary integer program is formulated for the optimal reassignment of planes to gates in response to day-of flight delays. This program minimizes the total walking distance of those passengers either connecting or originating at an airport whose boarding passes for affected...
