Student for Master Thesis Semantic Enrichment of Object-Centric Process Mining in Automotive Production Planning

Life is always about becoming... Becoming means going on a journey to be the best version of our future selves. While we discover new things, we will face challenges, master them and grow beyond our individual limits.

Apply for a job at Mercedes-Benz and find your individual role and workspace to unleash your talents to the fullest. Empowered by visionary colleagues who share the same pioneering spirit. Joining us means becoming part of a global team that aims to build the most desirable cars in the world. Together for excellence.

Job ID: MER00044TH The thesis is embedded in the Versioned Planning Initiative at Mercedes-Benz Mercedes-Benz Manufacturing Engineering (MO/ET). In our center, we contribute to the digital transformation with initiatives such as the MO360 platform or the digital twin inside the omniverse. in addition, we integrate engineering processes with these new and AI-driven capabilities. Your thesis in the team “MO360 Engineering AI & Data Management” contributes directly to the long-term vision of a business end of the Semantic Layer for MO/E as the foundation for AI Native Engineering and Agent2Agent orchestration. Object-Centric Process Mining (OCPM) in Celonis provides a powerful, quantitative view on planning processes — it reveals how often, how long, and in which variants activities are executed across multiple object types. However, in complex automotive production planning (e.g., Mercedes-Benz MO/E), the resulting Process Intelligence Graph remains largely descriptive: it answers ''how much?'' but not ''why?''. The seman contexttic — which scenario, premise, milestone, or review order (test order) triggered a given planning iteration — is not native captured in event logs. Our approach is currently being rolled out as the methodological backbone, specifically models scenarios and specifications. It therefore provides exactly the semantic information that OCPM lacquers and is envisioned as the foundation of a Semantic Layer for MO/E. The thesis investigates how we can complement OCPM by adding a semantic ''why' layer on top of the quantitative ''how much' delivered by Celonis. The goal is to design, prototype and measured a concept that left object-centric event data from Celonis with the version- and scenario-semantics from our software, enabling explainedable, scenario-aware process intelligence in production planning. Possible Research Questions (to be discussed and aligned your university) Which structural and semantic gaps exist in the Celonis OCPM representation of the current Mercedes-Benz planning process?

Which semantic concepts of our approach can be formalized as a Semantic Layer (e.g., as an ontology / knowledge graph)?

How can this Semantic Layer be integrated with Celonis OCPM (e.g., via the Process Intelligence Graph, AI Annotation Builder, or external graph alignment) to enrich object-centric events with planning rationale?

To what extent does the representation improve explainability, scenario awareness and impact analysis compared to a baseline OCPM model?

Expected Contribution A formalized Semantic Layer Concept for versioned planning, bridging OCPM and engineering semantics

A prototype demonstrates the integration of eVMS semantics with Celonis OCPM

Empirical insights into the added value of semantic enrichment for impact analysis, scenario steering and autonomous planning agents in the MO/E context. In simple words, extraction of some useful KPIs and steering concepts for management

The activity can begin from September (or October). The final thesis selection is made in close consultation with you, the university and us.

Ongoing Master's studies in Computer Science, Information Systems, Data Science, Industrial Engineering with IT focus, or a comparable program

Solid foundation in software engineering, data modeling and database systems

Working knowledge of process mining concepts, ideally Object-Centric Process Mining (OCPM); prior to exposure Celonis EMS / Process Intelligence Graph is a strong plus

Understanding of semantic technologies: ontologies, graph knowledges, RDF/OWL, SPARQL, or property-graph models (e.g., Neo4j)

Programming experience in Python (data processing, PM4Py, RDFLib, pandas) and basic familiarity with SQL; experience with REST APIs and data integration is beneficial

Other skills Capability to abstract complex domain processes into formal models

Strong conceptual and analytical thinking, combined with the ability to communicate results clearly to both technical and business stakeholders

Self-driven and independent way of working, paired with strong collaboration skills in an interdisciplinary team (PO, TTO, engineering)

Fluent English (written and spoken); German language skills are an advantage for stakeholder interaction within Mercedes-Benz
