The Department of Quantitative Economics at Maastricht University School of Business and Economics is looking to fill a PhD position. Requirements In multiple domains, there can be a welfare gain when parties work together. These cooperations lead to centralized optimization problems, where the total system is optimized. Such an optimization algorithm produces a solution and provides it to the various parties in the system. However, as said, this combined solving gives a welfare benefit; this solution is overall better compared to the situation when all parties would have optimized their own situation. This gain should be divided fairly amongst the parties. There are multiple techniques to do that, based on e.g. the Shapley value or the Gini Welfare function. To use the Shapley value, the original, computational expensive, secure optimization problem must be solved multiple times, adding much (time) complexity to the procedure. However, in many cases the various parties do not want to share information, not even the information needed to come to this central optimal solution. Secure multi-party computation (MPC) is a subfield of cryptography with the goal of creating methods for parties to jointly compute a function over their inputs while keeping those inputs private. This technique can not only be used in optimization, but also in the process of dividing the welfare gain. Note that making a method secure will, in most cases, create additional complexity to the calculations. This leads to the main goal of this project: create novel, secure, fair, and efficient welfare distribution mechanisms for secure (integer) optimization problems. The project will be based on two real world use cases: Multi-fleet management: complex optimization with competing logistic suppliers; Distributed smart grid: privacy-preserving distribution of sustainable energy. Candidates need to hold a master's degree (or be close to completion) in operations research, mathematics, computer science, or similar. Strong mathematical skills are required. Good proficiency in English (both oral and written) is required. For TNO, it is required for the candidate to pass a security screening (https://english.aivd.nl/topics/security-screening ) Candidates are expected to start preferably September 1. We offer 4-year positions. We have a large and culturally diverse PhD community in our department, and welcome enthusiastic, talented new PhD students. PhD positions are paid for, with minimal teaching obligations of at most 25%.
