Query: A simulation driven optimization algorithm for scheduling sorting center
  operations   Parcel sorting operations in logistics enterprises aim to achieve a high
throughput of parcels through sorting centers. These sorting centers are
composed of large circular conveyor belts on which incoming parcels are placed,
with multiple arms known as chutes for sorting the parcels by destination,
followed by packing into roller cages and loading onto outbound trucks. Modern
sorting systems need to complement their hardware innovations with
sophisticated algorithms and software to map destinations and workforce to
specific chutes. While state of the art systems operate with fixed mappings, we
propose an optimization approach that runs before every shift, and uses
real-time forecast of destination demand and labor availability in order to
maximize throughput. We use simulation to improve the performance and
robustness of the optimization solution to stochasticity in the environment,
through closed-loop tuning of the optimization parameters.
