| Summary: | <p>Scheduling workers in a trucking system for stripping and loading trucks is a
difficult and time consuming task that involves determining the optimal number of
workers. Once the number has been determined the operations manager has to assign
different trucks to the workers and has to determine the schedule of the workers. In the
thesis,we develop a mathematical model to solve the scheduling problem, with attention
focused on minimizing the number of workers required on a particular shift and on finding
the feasible assignments of workers to trucks and vice-versa. We show that this is a set
partitioning problem with an additional feasibility constraint which can be solved using the
column generation technique. An inherent characteristic of this problem that makes it
different from other set partitioning problems is that the arrival time and scheduled
departure tin1e is different for different trucks. We illustrate the model and the proposed
algorithmic approach by generating a schedule based on real data obtained from a trucking
company.</p> === Master of Science |
