Integrated Production Planning and Quality Control for Linear Production Systems Under Uncertainties of Cycle Time and Finished Product Quality
This work considers serial production systems with several process steps and a possible quality control at final step. It deals with the problem of optimizing planned lead time when the real lead time for each process is stochastic and the finished product quality is uncertain unless it is inspected. Three analytical models are proposed aiming […]

Optimization of multi-period supply planning under stochastic lead times and a dynamic demand
Supply planning and inventory control are vital in Supply Chain (SC) optimization processes for companies that aim to produce highest-quality finished product at lowest cost and right on time. Optimization means planners’ need to reduce average stock levels and determine the optimal safety lead-times. This study deals with a multi-period production planning problem with a […]

Towards Predicting System Disruption in Industry 4.0: Machine Learning-Based Approach
Industry 4:0 is the most recent industrial revolution that aims to improve not only the productivity in the 21st century, but also the flexibility, adaptability, and resilience of the industrial systems. It enables the collection of real-time data from industrial systems, Thanks to the development of Internet of Things (IoT) technology. Hence, analyzing online collected […]

Accuracy and Localization-Aware Rescheduling for Flexible Flow Shops in Industry 4.0
Industry 4.0 revolution aims to satisfy the manufacturing systems need to deal with the unexpected customers behaviour and market variation. Thanks to Internet of Things (IoT) technology, Industry 4.0 enables to collect and analyze real-time data about Cyber Physical System (CPS) components and hence to detect and react to emergent disruptive situations as quick as […]

Genetic algorithm to optimize unloading of large containers vessel in port of Tripoli-Lebanon
The quay crane scheduling problem (QCSP) in the lebanese port (Tripoli) is discussed in this study. It consists in assigning each crane to a set of bays for a given vessel, while sequencing the unloading of these bays. In a previous study, we discussed two exacts methods whose main drawback is the difficulty to obtain […]

Proteus vs. social identity effects on virtual brainstorming
Avatars are known to influence behaviour through their individual identity cues (Proteus effect) and through their shared identity cues (Social identity effect). The aim of this study was to investigate these two processes in a crossed design, in order to examine their interaction in the context of a brainstorming task. To activate the Proteus effect, […]

Optimization of Transportation Collaborative Robots Fleet Size in Flexible Manufacturing Systems
The current economic context is uncertain and highly competitive, where companies seek to reduce their production cost and adapt production systems to market needs. Since consumer behaviour becomes more and more unpredictable within shorter and shorter product lifetime, flexible manufacturing systems are introduced to allow company to adapt their production to the market without changing […]

Packaged Bio-Waste Management Simulation Model Application: Normandy Region, France
With rapid technological development, population growth and urbanization, nations and governments are forced to face the increasingly large quantities of urban waste generation. Meanwhile, recycling and utilization of solid waste to regenerate energy, saving natural resources and reducing air and waster pollution have become big concerns to the whole world. This paper describes a decision […]

Wind Turbine Components Classification based on Failure Causes for Proactive Maintenance Simulation
Predictive, proactive and reliability-based maintenance are considered among the most widely used approaches in the field of maintenance optimization of wind turbines. Nevertheless, most existing models are designed to optimize the maintenance of a single component of a wind turbine and do not take into consideration the different dependencies that exist between components, which does […]

Modeling the scheduling of a multi products pipeline: A case study in Algeria
The scheduling of the supply chain of the oil industry plays an important role for both international and national industrials sectors in order to provide oil products having a great place in the daily life of the individual and factories. Further, the unavailability of these products may lead to the cessation of activity and significant […]

Conception et développement d’instruments pour articuler la formation et le travail
A travers deux cas, nous évoquons le rôle de la conception d’outils afin que leurs utilisateurs développent des compétences attendues dans leur activité professionnelle. Un est issu de mon travail de thèse et prolongé pendant les années qui ont suivies ; l’autre emprunte à la mise en place des FabLabs à CESI.

Towards a Fractionation-based Verification: Application on SysML Activity Diagrams
This work contributes to reduce the cost of the verification process of model-based systems, especially the ones designed as SysML activity diagrams, by relying on the concept of diagram calls defined in SysML standard. By exploiting the diagram calls concept, we propose a mechanism to transform a given diagram into its equivalent fractal (hierarchical) form. […]
