Conference Paper
This paper addresses the problem of supervised classification of time event logs of two classes: positive and negative population. The key idea of this paper to explain classification is to determine some process model that fits well the positive event logs and poorly the negative ones. More specifically, we introduce formal definitions of event lo...
Article
The problem of determining the optimal process model of an event log of traces of events with temporal information is presented. A formal description of the event log and relevant complexity measures are detailed. Then the process model and its replayability score that measures model fitness with respect to the event log are defined. Two process mo...
Conference Paper
Full-text available
Considering the globally aging population, one of the main challenges the healthcare system would have to face is to help elderly people stay at home in good health conditions and as long as possible. Recent advances in technologies answer this need with Smart Homes and Ambient Assisted Living programs. Data collected by the sensors are labeled and...
Conference Paper
Full-text available
With the global population growing older and more vulnerable, healthcare systems are considering new approaches to maintain people autonomous in their own homes. Recent advances in pervasive computing technologies have opened up new opportunities to unobtrusively monitor human behavior at home. Sensors data related to the activities of daily living...
Conference Paper
Comparison of cancer treatment protocols against patient history is important to assess the efficiency of chemotherapy protocols. However, manual identification of protocols is not possible when considering a large population of patients. This paper proposes a new method called ATLAS (Analysis of Treatment Lines using Alignment of Sequences) to tac...
Poster
Full-text available
Event logs are a widespread type of data structure carrying information of time and ordering of events. As the complexity increases when time-dependent processes are considered, human understanding of predictive models is a lever for acceptability and practical deployment. We present here a new binary classification algorithm, created for event log...

Les aidants de patients atteints de maladies chroniques subissent un épuisement quotidien dans leur vie. Bien que les soins de répit semblent une perspective prometteuse, aucune analyse quantitative n'a été fournie pour démontrer son impact sur les aidants. Cet article présente un état de l'art sur les services de répit ainsi que l'épuisement des a...
Conference Paper
Respite care is a new service to decrease burnout risk of caregivers. Hospitalization related to caregivers burnout are costly and should be avoided. Pre-identification of caregivers with severe burnout is crucial to better manage respite care services through smart admission policies and health resources management. In this article we propose a mi...

Data has become highly valuable for many of companies and organizations. With the development of advanced data science methods and computer power, extraction of intelligible knowledge using predictive models has become helpful in decision-making. In healthcare, opportunities are numerous and Machine Learning applications may help to better understa...
Article
Hospitalizations via the emergency services of the elderly represent on average 41% of the stays. The family physician is aware of the deleterious effects of using emergency rooms and know that intensive use contributes to the disorganization of these services. The provision of a telephone line, enabling doctors to have direct access to a geriatric...

Article
Home Health-Care (HHC) is a concept slowly expanding over time, introduced to reduce pressure on inpatient hospital beds by providing care to patients at home. Nowadays, HHC centers are able to undertake more technical complex care such as (but not limited to) end-of-life care, chemotherapy and rehabilitation. This article accomplishes two main obj...
Conference Paper
This paper presents a method to automatically create stochastic simulation models of clinical pathways from raw databases. We introduce an automatic procedure to convert a process model, discovered with process mining, into an actionable simulation model. The concept of state charts is used and enriched to incorporate the distinctive features of he...
Conference Paper
The analysis of clinical pathways from event logs provides new insights about care processes. In this paper, we propose a new methodology to automatically perform simulation analysis of patients' clinical pathways based on a national hospital database.

Conference Paper
This paper addresses the performance evaluation and verification of territorial healthcare information systems. For this purpose, we propose a new class of timed Petri nets, called THIS nets (Territorial Healthcare Information Systems), which formally describes patient care-pathways, relevant information flows and their interactions. THIS nets are...
Conference Paper
Health systems around the world have been continuously subject to many questions about their performance. In order to improve the functioning of such systems, Health Information Systems (HIS) and Technologies (HIT) are deployed to support patient care pathways and ensure information exchange between health structures, actors of patient care. The ai...

This paper presents a simulation-optimization approach based on mathematical programming representation of event dynamics for capacity planning and appointment scheduling in blood collection systems. The mathematical model is formulated as a multi-criteria mixed integer programming (MIP) which corresponds to the stochastic counterpart approximating...
Article
In this paper, we propose a two-step bloodmobile collection planning framework. The first step is the annual planning to determine weeks of collection at each mobile site in order to ensure regional self-sufficiency of blood supply. The second step is the detailed weekly planning to determine days of collections at each mobile site and to form corr...

Excessive waiting time in Emergency Departments (ED) can be both a cause of frustration and more importantly, a health concern for patients. Waiting time arises when the demand for work goes beyond the facility's service capacity. ED service capacity mainly depends on human resources and on beds available for patients. In this paper, we focus on hu...
Article
This paper addresses the problem of joint facility location and capacity planning of hierarchical service networks in order to determine when and where to open/close service units, their capacity and the demand-to-facility allocation. We propose a new hierarchical service network model in which both the facilities and customers have nested hierarch...

Bonjour, j'espère que ce dépôt tardif n'est pas rédhibitoire. Il s'agit d'un travail assez avancé qui présente des originalités sur la modélisation de la robustesse et l'intégration des tournées dans la charge de travail. La méthode de résolution tire bénéfice de ces modèles et a un potentiel de généralisation.
Article
Full-text available
In this paper, we propose a new modeling methodology named MedPRO for addressing organization problems of health care systems. It is based on a metamodel with three different views: process view (care pathways of patients), resource view (activities of relevant resources), and organization view (dependence and organization of resources). The result...
