A Comparison of Heuristics for Assigning Individual Employees to Labor Tour Schedules

The labor tour scheduling literature has focused on the development of schedules, and with a few exceptions, employees were assumed to have identical cost and productivity. Even the few exceptions in the literature that solved tour problems considered employees within a work group to have identical cost and productivity. In this paper we evaluated heuristics for assigning individual employees – who differed in cost and productivity – to labor tour schedules. Our results showed that considering productivity levels when assigning individuals to tours increased profitability. We found that a simple managerial heuristic of assigning individuals in descending order of their productivity to cost ratio was both fast and effective over a broad range of service environmental scenarios.
