Abstract

Microsimulation aims at mimicking a real population under scrutiny and simulating its temporal and spatial evolution. This thesis proposes first two applications related to actual problems: the creation of a synthetic population of space debris, causing potential damages to functional satellites and the forecast of the health needs of the elderlies for Belgium until 2030. Then, the observed limitations of the methods generate new methodological research questions. Hence, the impact of specific orders of the application of the sub-models for a discrete time simulation with a fixed time-step of a synthetic population is investigated and quantified. Then, we propose the calendar based approach consisting in fixing birthdays for each agent and a date of death for the dying agents. This reduces the variability of the results. These studies about the evolution of synthetic populations induced theoretical questions whose scope goes beyond the presented framework. Indeed, noticing that simulating the occurrence or not of an event is equivalent to perform a binary classification, we delved into the problem of highly unbalanced classes with unobserved variables. These achievements have been obtained by developing and comparing a feedforward neural network and a logit discrete choice model.

Abstract

This thesis investigates the influence of outsourcing on supply chain resilience within the Moroccan pharmaceutical sector, using case studies of Sanofi, Pharma 5, SOTHEMA, and Cooper Pharma through the Eisenhardt method. The research reveals that outsourcing non-core functions, such as logistics and secondary manufacturing, enhances operational efficiency and flexibility, enabling companies to concentrate on core activities. Diversified outsourcing partnerships, strong supplier relationships, and advanced technologies are identified as critical in mitigating risks and ensuring supply continuity. Regulatory compliance in outsourcing decisions is also crucial for maintaining quality and integrity. Despite limitations like the small sample size, the study provides valuable theoretical and practical insights, highlighting the importance of strategic outsourcing, robust partnerships, and technology integration in strengthening pharmaceutical supply chain resilience.

Abstract

The purpose of this master's thesis is to comprehensively investigate and analyze various risk
management strategies that contribute to enhancing supply chain resilience in logistics
companies in Luxembourg. By identifying, assessing, and addressing potential risks, the study
aims to provide insights into how businesses can navigate uncertainties and disruptions while
maintaining a robust and adaptable supply chain.

Abstract

Sales forecasting occupies an important place in manufacturing companies, especially in the B2B sector. It can help organisations optimise their supply chain management, resource allocation and target setting. There has been some development made in the different models and new techniques are derived from existing ones. However, there are still some important challenges and limitations in providing accurate forecasts. 
This thesis aims to answer three main questions about which technique and model would be adequate to be used in sales forecasting and whether external data should be included in the forecasting model and what kind of data. Furthermore, it discusses the different statistical and machine-learning model setups applied in search of the optimal outcome. The answers to these questions determine whether of this proof of concept is satisfactory or not. The conclusion determines if a statistical or machine-learning forecasting model could present an alternative or an extension to conventional judgemental forecasting. 
The Prophet model which has been developed by the Facebook engineering team turned out to be the best-performing model, whereas the artificial neural network did not perform well based on the chosen evaluation metrics. To better understand the results and put them into context, they are visualised in the BI software “Tableau”. 
Improvements in terms of accuracy and precision could still be made by extending the feature selection and taking more or different external datasets into consideration.

Abstract

À l'heure où nos zones urbaines sont confrontées à des défis sans précédent liés à la congestion du trafic, à la pollution de l'air et aux problèmes environnementaux, la mobilité douce s'avère être une approche prometteuse pour façonner un avenir urbain durable et équilibré. Connu sous le nom de mobilité active, ce concept place les citadins au centre du paysage urbain en encourageant les modes de déplacement actifs tels que la marche, le vélo et les transports publics bien planifiés. Cette approche globale va au-delà de la simple réduction de la dépendance aux véhicules motorisés et vise à améliorer la santé et le bien-être des habitants tout en renforçant les liens sociaux et en préservant l'environnement pour les générations futures.Aujourd'hui, face à la nouvelle tendance de la mobilité douce et aux nombreux nouveaux engagements de la Région wallonne, l'Idema a souhaité relever le défi de s'implanter sur le marché de la mobilité douce. L'objectif de cette étude est d'examiner le positionnement de l'Idema et de trouver des pistes d'amélioration de sa notoriété afin de proposer des solutions et des recommandations pertinentes pour leur permettre de développer une nouvelle stratégie afin de s'implanter au mieux dans ce nouveau secteur.Pour répondre à la question de recherche, une analyse théorique liée à la stratégie et aux pratiques de l'entreprise a été réalisée. Pour répondre à la question de recherche, une analyse théorique liée à la stratégie et aux pratiques de l'entreprise a été réalisée. Des entretiens avec des acteurs clés du secteur ont permis de confirmer les informations théoriques. Sur la base de l'ensemble des informations recueillies, nous avons pu formuler un certain nombre de recommandations à l'entreprise.Ce rapport est divisé en plusieurs parties. La première est une analyse de l'entreprise d'accueil et une contextualisation du projet et de la question de recherche. La seconde est une analyse interne et externe d'Idema afin de comprendre le secteur dans lequel elle opère. La troisième étape consiste en une étude du positionnement de l'entreprise. Ensuite, nous analysons comment Idema pourrait améliorer sa réputation. De plus, nous réaliserons une analyse qualitative qui apportera un éclairage supplémentaire à cette étude. Enfin, nous terminerons cette thèse par des recommandations pour l'entreprise.
