chaire miai G-SCOP


In short:

The objective of this chair is to develop novel and self-adaptive decision making methods for data driven and ultimately self-reconfigurable network of production systems (supply chains) in the context of industry 4.0. Optimization, simulation and AI techniques will be coupled to this end.

Scientific objectives and context
Operations and supply chain management (O&SCM) involves in general some form of explanatory and predictive analytics (forecasting, simulation) and prescriptive analytics (optimization) that are often used together. Despite their adequacy to solve O&SCM problems, simulation and optimization may lack precision or speed as system complexity increases, may fail to handle complex objectives and/or constraints, and lack reactivity to cope with fast evolving environment of industrial and service systems. To overcome these downsides, we propose to develop advanced decision making tools by coupling optimization and simulation with AI techniques.

Research directions
  • O&SC applications often require (or generate) domain-specific knowledge resulting in significant amount of customization of the algorithms used. We will explore data analytics and machine learning to extract generic knowledge, which can be used to better characterize the behavior of an algorithm and to anticipate its performances.
  • Techniques based on reasoning such as constraint programming could be better suited to handle fundamental production planning problems (e.g. lot sizing), in the presence of complex objectives and additional combinatorial constraints. We will explore reasoning mechanisms to design new solution techniques that deliver fast and high quality solutions for such problems, with a quality guarantee (an optimality gap) to the decision maker. A valuable contribution for practical use is to incorporate these mechanisms into industrial information systems (e.g. a demonstrator using an open source ERP such as Odoo)
  • When a decision aid tool is deployed in industry, the initial fine-tuned parameters are rarely updated during utilization. Data analytics and learning mechanisms will be included to develop self-readjusting decision tools, which can adapt to an evolving environment.
  • Simulation is commonly used in industry for “what-if scenario analysis”. Today, these scenarios are mostly defined based on manager’s own judgment and expertise, and may not include all potentially promising scenarios. AI techniques can help in defining the scenario bases for high quality solutions and fast analyses.

Motivation and expected impact
Today’s markets are characterized by high product diversity, uncertain and volatile demand, shortened product-life-cycles and production lead times. To stay competitive, the companies need to deploy flexible manufacturing systems, robust and traceable supply chain networks, and agile, self-adapting operations planning processes. While “Industry 4.0” provides the technological background (e.g. IoT, Io(Thinking)T, smart sensors,…), the methods developed in this chair will provide the necessary decision-making tools, to this end.
