I am an associate professor of smart manufacturing and supply chain planning at the University of Twente, focusing on resilience of our production systems and supply chains.
I received my Ph.D. from Middle East Technical University, Turkey, in 2010. I worked as a researcher and instructor at Cankaya University, Turkish Military Academy, Eindhoven University of Technology and Erasmus University Rotterdam (part-time). I have been involved in research projects on proactive after-sales service logistics for capital goods (ProSeLo, ProSeLoNext) and proactive maintenance planning (MANTIS).
My research lies in enhancing the resilience and agility of supply chain and production systems by using data embedded in these systems and enabling predictive & and proactive planning in supply chains by combining model- and data-driven methods. My research focuses on two application areas: (i) proactive after-sales service logistics, predictive maintenance, and supply chain control towers for capital goods manufacturers, and (ii) smart, data-driven production and supply planning particularly for SMEs.
I am currently working on three project initiatives: (1) PERISCOP and smaller projects around it on AI-empowered flexible production and supply planning for SME+s, and coordinating this project and participating as a co-lead, (2) DESIRE on smart, sustainability, and resilient manufacturing with a bit broader focus with a role of co-applicant and WP-leader, and (3) OpsCenter on service control towers for after-sales service logistics and participating in this project as a co-applicant.

Predictive Real-time Integrated Smart Control of Operations and Planning (PERISCOP) for Manufacturers
PERISCOP
Dutch high‐tech manufacturers operate in competitive markets characterized by highly volatile demand and supply. Their planning and scheduling tools do not have the level of proactivity and flexibility to accommodate these dynamic changes. Artificial intelligence (AI) can provide the necessary knowledge and techniques to address the complexity of planning and scheduling processes enabling these organization to prosper in their markets dominated by volatility. However, manufacturers, particularly SMEs, do not know whether, where, and how to use AI. They typically have limited capabilities, digital infrastructure, business culture, and human resource to adopt this technology. By using AIempowered flexible and proactive planning, manufacturers can improve their customer responsiveness, reduce their costs, time to market as well as their excess material losses and costly reactive adjustments. These increase competitiveness as well as sustainability of manufacturers. Considering that Dutch high-tech industry employs hundreds of thousands of employees and creates more than hundred billions of euros of production value, these advancements are crucial for maintaining a sustainable Dutch economy and society. In PERISCOP, by particularly focusing on SMEs, we develop and enable the adoption of advanced AI-empowered decision and planning methods that makes high-tech manufacturers more proactive and flexible and we concreate modules to implement them. We employ use cases of manufacturers at different adoption levels of AI, to build, test, and demonstrate our methods. To foster a large‐scale adoption, together with manufacturers, we cocreate generic, modular solutions; clear roadmaps to transform business processes, digital infrastructure, employees' skills to adopt AI in planning and decision-making. The project has been submitted to NWA Perspectief 2021/2022 round.
Operations control centers for sustainable after-sales services (OpsCenter)
OpsCenter
By 2030, the European Union aims to halve its carbon emissions. It is therefore key that high-tech equipment has a minimum footprint, with low cost and high equipment availability. We aim to achieve this by setting the new standard of delivering after-sales services, such as maintenance services and the supply of spare parts and service engineers. To this end, we develop operations control centers in which data and domain knowledge on the equipment and the after-sales service supply chain is transformed into actions using artificial intelligence. Combined with a redesign of the after-sales service supply chain and the business models of the involved companies, we achieve minimum footprint and costs, with high equipment availability. The project has been submitted to NWA Perspectief 2020 round now it is in the last assessment round.
