The Human Resources Assignment with Multiple Sites Problem

Abstract

Human resources assignment is the process of creating an employee's assignment in order to meet the demand of a set of tasks over time horizon. Many research works have been developed for similar problems in many field areas like health-caring, manufacturing, transportation… However in our study, we approach a general case where tasks do not have a specific daily or weekly pattern. Employees can be assigned to more than one task per day and taking in consideration multiple sites. The objective of our study is to find a feasible solution that respect different constraints relative to labor regulations and a constraint relative to multiple sites, balance the workload over employees and minimize overload hours. We propose a mixed integer programming model and a key performance indicator based heuristic to solve this problem. The results of the heuristic are very promising.
