In the team of AROBAS, IBISC, at University Evry-Paris Saclay, France, we
are offering a Master 2 research internship for up to 6 months, starting at
the beginning of February 2025. The internship will take place at the
University of Evry-Paris Saclay, at the IBISC laboratory. Evry is located
25.0 km from the center of Paris and 45 minutes from the center of Paris by
RER D. If you are interested in operational research and would like to
pursue a career in this field, do not hesitate to contact me. Details about
the internship topic and contact information for applying are below:
*Subject:* Integrated closed-loop supply chain and disassembly line
balancing optimization under time-of-use electricity pricing
*Context and missions*
With growing concerns about environmental sustainability, climate change,
and resource depletion, in recent years, companies and consumers have
increasingly focused on circular economies and practices that minimize
waste. The rise of sustainability and environmental awareness has also
fuelled the interest in closed-loop systems. A *Closed-loop supply
chain* (CLSC)
refers to a system where products, materials, or components are returned
after their useful life for reuse, recycling, remanufacturing, or proper
disposal. Unlike a traditional "open-loop" supply chain, which follows a
linear flow from production to consumption and then disposal, a closed-loop
supply chain seeks to minimize waste and maximize resource recovery by
bringing products back into the production process.
A disassembly line aims to efficiently separate a product into its
components for reuse, recycling, or proper disposal. Regarding the
*Disassembly
Line Balancing Problem, *the main objective is to *assign disassembly tasks
to workstations* in a way that minimizes the total cycle time while
ensuring that each workstation is neither overburdened nor underused*.* While
disassembly and closed-loop supply chain are distinct concepts, they are
closely connected, especially in industries where product recovery,
recycling, and remanufacturing are central to business models. By
optimizing disassembly processes, businesses can improve the overall
effectiveness of their closed-loop systems, ensuring that valuable
materials are efficiently extracted and returned to the supply
chain. Despite this strong connection between the two concepts, they have
been rarely studied in an integrated way
The disassembly industry is often energy-intensive and most previous DLBP
studies focus on only minimizing the quantity of used energy but ignore
energy cost saving under Time-of-Use (TOU) tariffs. To the best of our
knowledge, (TOU) tariffs have not been addressed in disassembly line
balancing problems. Based on all these findings, incorporating closed loop
supply chain and disassembly line balancing decisions under the TOU tariffs
will provide interesting insights to decision makers and researchers in the
field.
* The following phases will be carried out during the internship:*
· Conduct a literature review on integrated problems of closed-loop
supply chain and disassembly line balancing.
· Propose an appropriate mathematical model.
· Develop exact or approximate solution methods and validate the
proposed approaches using data.
*Profile required: *
We are looking for a candidate in M2 or in their final year of an
engineering school, specialized in Operations Research, Combinatorial
Optimization, Computer Science, Industrial Engineering, or a related field.
• Formulation of complex problems (LP, MILP).
• Strong skills in algorithms and programming (C++ or Python)
• Good proficiency in English for documentation and result communication,
French knowledge is not required.
