Item Conception et développement d’une plateforme intelligente de soins médicaux à domicile.(Université Mohamed El Bachir El Ibrahimi B.B.A., 2025) - Bengrine Abderrahmane; Hammache Riadh; Djelloul Raid; Benmessaoud Wassim; Slimane Hadjrioua; Firas BensalemDigital services play a crucial role in modernizing the healthcare sector, where efficiency, traceability, and coordination are key. In Algeria, home nursing care still faces a lack of advanced technological tools. The MediCall project aims to bridge this gap by developing an intelligent and secure digital platform dedicated to managing and booking home nursing services. The platform acts as a reliable intermediary between patients and nurses, automating the care process from the initial request to payment. It consists of three interconnected applica- tions : a web application for administration and supervision, a mobile application (Flutter) for patients and nurses, and a desktop application for medical coordinators to manage and monitor operations. The system also integrates an intelligent server powered by artificial intelligence, featuring a medical chatbot capable of providing accurate, contextualized responses — enhancing user experience and service efficiency.Item Khososi(Université Mohamed El Bachir El Ibrahimi B.B.A., 2025) M.

We specifically focus on global similarity methods, which leverage the entire network structure to estimate the likelihood of a link between two nodes. Five methods are studied and compared : Shortest Path, SimRank, Newton’s Gravitational Law Index (NGLI), Katz Index, and Common Neighbor Distance (CND). After presenting the theoretical foundations of graph theory and complex networks, we implemented these methods using Python and applied them to several real-world networks from different domains (biology, transportation, social networks, etc.). The performance of each method was evaluated using standard metrics such as precision, recall, F-measure, and accuracy. The results show that each method has its strengths depending on the network structure, and no single method consistently outperforms the others. This study thus provides valuable insights to guide the choice of link prediction techniques based on specific application contexts.Item Etude du problème d’optimisation de la distribution d’eau Cas de la ville de Bordj Bou Arréridj(Université Mohamed El Bachir El Ibrahimi B.B.A., 2025) Anfel BEN ABBES; Houda TAIAROptimizing water distribution is a crucial challenge in urban planning and infrastructure management. This work is part this strategic axis, which deals with the problem of optimizing water distribution in the city of Bordj Bou Arreridj, by reducing the energy consumption of pumps while ensuring an efficient distribution plan. This problem was modeled as a linear program composed of two objective functions and several constraints that guarantee pumping optimization while satisfying the needs of all areas of the city of Bordj. For the resolution, we used the Python programming language and the package "Pulp". The results obtained show the optimization made on the current energy bill.Item Allocation efficace des ressources hospitalières à l’aide de techniques d’optimisation Étude de cas : Hôpital Bouzidi Lakhdar(Université Mohamed El Bachir El Ibrahimi B.B.A., 2025) Silya Ouidir; Fatiha KraifaThis research addresses one of the most important operational issues, namely the question of resource allocation in emergency departments. This challenge consists in allocating resources in accordance with needs, taking into account patient severity. The main objective of this work is to improve the management of human and material resources in emergency departments. A resource allocation system has been adopted as the main mechanism in the proposed mathematical model. This model is based on integer linear programming to improve the distribution of resources while integrating the degree of severity of the patient’s condition. The resolution of the model was carried out using an intlinprog function under MATLAB software. The results obtained show a significant reduction in resource consumption, as well as a significant improvement in the organization of patient flow. To evaluate the effectiveness of the proposed methodology, real data were used, collected from the Bouzidi Lakhdar Hospital, located in the wilaya of Bordj Bou Arreridj.Item Agrinity - Smart Agriculture System(Université Mohamed El Bachir El Ibrahimi B.B.A., 2025) SAID HADDAD abdel hakim; NOUIOUA djamel eddine islemAbstract This project presents the design and implementation of a Smart Agriculture System aimed at improving agricultural efficiency through the integration of hydroponic cultivation, IoT technologies, and Operations Research (OR) methods.

Due to the combinatorial nature of feature selection, traditional meth ods often lack the scalability and adaptability required for real-world problems. In response, this thesis investigates the application of intelligent metaheuristic algorithms to feature selection in both supervised and unsupervised learning settings. First, a comparative analysis of the Equilibrium Optimizer (EO) and Henry Gas Solubility Optimization (HGSO) algorithms is conducted for supervised classification tasks. Both algorithms are adapted to a binary feature space and evaluated on benchmark datasets using classification accuracy and feature reduction as performance criteria, highlighting their respective strengths and motivat ing a hybrid approach. Consequently, this thesis proposes HGSOEO, a hybrid algorithm that integrates the complementary exploration and exploitation capabilities of HGSO and EO. The proposed HGSOEO algo rithm is evaluated on the Twitter Spam Detection dataset and demonstrates superior performance in terms of classification accuracy and the number of selected features when compared to conventional metaheuristic and classical feature selection methods. Furthermore, the application of EO is extended to feature selection for clustering tasks, where labeled data are unavailable, by employing clustering validity criteria such as the Adjusted Rand Index (ARI) to guide the selection process. Experimental results across multiple datasets confirm the effectiveness and robustness of the proposed approaches. Overall, the findings of this thesis demonstrate that intelligent metaheuristic algorithms provide efficient and scalable solutions to the feature selection problem in both supervised and unsupervised learning contexts.Item Étude empirique entre les algorithmes heuristiques et métaheuristiques pour le Problème du Voyageur de Commerce(Université Mohamed El Bachir El Ibrahimi B.B.A., 2025) Boumerta Maram; Messadek AichaThis thesis analyzes heuristic and metaheuristic methods to solve the Traveling Salesman Problem (TSP), comparing their efficiency in terms of speed, solution quality, and complexity.
