Energy-Based Workforce Scheduling Problem:
Mathematical Model and Solution Algorithms
Kriangchai Yaoyuenyonga and Suebsak Nanthavanijb*
ABSTRACT: A workforce scheduling problem to schedule the minimum number of workers to perform a set of
physical tasks such that their daily energy capacities are not exceeded is discussed. Firstly, a mathematical
model is formulated. Two heuristics and one exact algorithm are then explained. Based on our computational
experiment, a hybrid procedure consisting of the above mentioned algorithms is found to be very efficient
in solving this workforce scheduling problem to optimality.
