Assessment of assignment policies of users in medico-social service sector

Abstract

This paper is focused on the assignment of users to medico-social institutions. The main goal is to study if alternative assignment policies can improve global response to users' demands and assess the performances of each alternative compared to the current practice. We formulated a mathematical model of the user assignment to medico-social structures and professionals, under constraints of resource capacity, professional's skills and user requirement covering (formulated in an individual support project). The alternative assignment policies allow respectively to partially cover the need of users, and to authorize the involvement of several structures and several professionals in the response to the request. This model is solved thanks to a mixed ILP solver, following a lexicographic approach with regard do the partial covering policy. We used real size data gathered in a cluster of institution for disabled children and teenagers. We present and compare computational results over several scenarios, highlighting the improvement provided by alternative assignment policies.
