Abstract

Home Health Care (HHC) service is an alternative to the conventional hospitalization. The goal is to deliver medical, paramedical and social services to patients at their homes, which help them to improve and keep their best clinical, psychological and social conditions. Many resources contribute the HHC service delivery, including human resources (e.g., nurses, physicians, physiotherapists, etc.) and material resources (consumable and non-consumable) . Since many resources involve, there are many critical issues that should be considered explicitly. Among these, we focus on the assignment of operators to patients or visits (i.e., deciding of which operators will take care which patients) , and the routing process of these operators (i.e., deciding in which sequence each operator will visit patients assigned to him/her). In particular, many of the HHC providers pursue the continuity of care which is maintaining the same operator throughout the time of the patient in the system. However, due to operational efficiency it can not be always adopted. Our purpose is to provide different models for the assignment and routing problems with and without continuity of care and to compare these models to find the most efficient and beneficial ones in terms of workload balancing levels, total travel and service times of the operators.
