Within the framework of economic constraints and demographic changes which the health care sector is confronted to, the Home Health Care (HHC) which has been created sixty years ago, has known an important growth during this last decade. The main objective of this alternative to the traditional hospitalization consists in solving the problem of hospitals' capacity saturation by allowing earlier discharge of patients from hospital or by avoiding their admission while improving or maintaining the medical, psychological and social welfare of these patients. In this thesis, we are interested in the operations management within the HHC structures. In the first part of this thesis, we develop a qualitative analysis of the operations management in the HHC context. More specifically, we identify the complexity factors that operations management has to face up within this type of structures. For each complexity factor, we discuss how it can affect the organization of the care delivery. These factors pertain to the diversity of the services proposed, the location of care delivery, the uncertainty sources, etc. Thereafter, we survey operations management based models proposed in the literature within the HHC context. Based on this literature review, we identify several emerging issues, relevant from an organizational point of view, that have not been studied in the literature and thus represent unexplored opportunities for operations management researchers. In the second part of this thesis, we are interested in the partitioning of the area where the HCC structure operates into districts. This districting approach fits the policies of improvement of the quality of care delivered to patients and the working conditions of care givers as well as costs' reduction. We begin by proposing a classification of the different criteria that may be considered in the districting problem. We then propose two mathematical formulations for the HHC districting problem for which we consider criteria such as the workload balance, compactness, compatibility and indivisibility of basic units. After that, we present a numerical analysis of the computational experiments carried out on randomly generated instances to validate these two models. We also present two possible exploitations of these models and propose two extensions to these basic formulations. After formulating the problem with a static approach, we also develop a dynamic extension which allows the integration of the different variations that can be observed within the activities of an HHC structure from period to period. We then introduce a new partitioning criterion that concerns the continuity of care evaluated on the basis of two sub-criteria. Depending on the preferences of the decision-makers concerning the sub-criteria related to the continuity of care in the districting problem, we then distinguish three scenarios for which we propose the associated mathematical formulations.
