Analytics for Cyber-Physical Service Systems
Motivation
 Cyber-Physical Systems address connection of physical and digital word through influence and control
 Due to declining hardware costs (i.e., sensor technology) and advanced connectivity capabilities, more and more
products become Cyber-Physical Systems
 Massive increase of data volume generated by Cyber-Physical Systems along complete value chain of a product
 RQ: How can Analytics enhance Cyber-Physical Systems considering the complete value chain?
Approach
 Identification of problems regarding the general design and
architecture of Cyber-Physical Service Systems
 Development of analytics method(s) to overcome these problems
 Verification of organizational impacts of developed analytics
method(s)
First Results
 Feasibility of applying advanced analytics methods for condition
monitoring of non-observable components in a sealing use case

Privacy- and confidentiality-preserving analytics across company borders:
Meta and Transfer Learning in smart service systems
Challenge
 Data in smart service systems is distributed throughout entities and an exchange of data is not
possible due to confidentiality issues
A: comprehensive analyses can not be performed  No holistic insights
 Entities often face similar analytics challenges or possess similar data
B: an exchange of analytical knowledge or models is prevented due to confidentiality issues and
its complexity  Re-invention of the wheel
Method / Approach
 A: Perform comprehensive analyses through meta machine learning to derive holistic insights in
settings, where data about one common context that needs to be analyzed is distributed across
entities
 B: Reuse models by applying transfer machine learning in settings, where multiple entities
possess similar data and face similar analytical problems
Benefit
 A: Through meta machine learning and a “directed stacking” approach, we enable privacy- and
confidentiality-preserving analytics across company borders
 B: Through transfer machine learning, we enable a privacy- and confidentiality-preserving
transfer of analytical knowledge in form of models

Ensuring Validity of Predictive Services over Time
Motivation
 Various industries rely on predictive services based on data streams
for (better) service offerings
 Over time, context or data may change and false decisions might be
taken based on predictive service
 RQ: How can we design efficient and effective tools which ensure the
long-term validity of predictive services?
Approach
 Collection of research papers that are dealing with changing data
streams on real use cases
 Identification of algorithmic options and challenges in operation
 Semi-structured expert interviews with machine learning practitioners to
identify solution strategies in practice
First Results
 Taxonomy with design options for creating valid predictive services over time and classification of existing research
approaches into this taxonomy

Designing Systems for Automated and Data-Driven Field Service Planning:
Leveraging Machine Learning and Operations Research for Service Operations
18
Motivation
 Service operations in the context of industrial maintenance (i.e. the scheduling of maintenance,
repair, and overhaul) is surprisingly difficult. In practice, planning performance largely depends on the
ability of service providers to manage complexity and uncertainty during three planning phases (see
below).
 Companies need to detect, specify, and prioritize service demand before technicians can be
assigned—all tasks currently conducted manually by domain experts based on their tacit knowledge.
 Emerging technologies (i.e. cyber-physical systems) and changing customer demand (i.e. asset
outsourcing) are driving the adoption of new maintenance policies (i.e. prediction-based) and
contracts (i.e. performance-based). Understanding how these phenomena can reduce the
dependence on tacit knowledge and change how services are delivered is the focus of this research.
Approach
1. Data-Driven Demand Estimation: Data from cyber-physical systems can be used to remotely
approximate the service demand of managed machinery by modelling common deterioration patterns
(e.g. wear out or fatigue) and detecting abnormal behaviour of individual machinery.
2. Data-Driven Planning Preparation: Detected service demand can be translated into specified work
orders (e.g. required service duration, skills, or expected costs) by analysing historic work orders,
technician reports, and information available on asset usage & context.
3. Automated Work Order Prioritization and Planning: Anticipatory planning can help solution
providers (i.e. performance-based contracts) objectively prioritize and plan work orders.

System-Oriented Service Delivery in Service Systems
Motivation
 provider-oriented service delivery in service systems
(= service delivery such that provider costs are minimal)
 customers have delivery-dependent costs (e.g. due to delayed service delivery)
that are not taken into account during provider’s delivery resource allocation
 provider-centric delivery decision making leads to an inefficient allocation of
delivery resources from a system’s viewpoint
Approach
 system-oriented service delivery that minimizes total system costs
(= sum of provider‘s delivery and customers‘ consequential costs)
 mechanism to enforce benefit and loss sharing among participants
Results
 cost-minimal service delivery from a system perspective
 prevent individual losses through loss/benefit sharing
 Pareto-improvement over provider-oriented service delivery
 additional value allows for business model innovation

Vertical Integration Analytics – A Milling Use Case
Motivation
 Nowadays, advanced analyses (like Machine Learning) are usually not performed across company borders. However,
this promises new insights, business models and potential for cooperation.
 Use case:
 Tool life in Milling operations varies for theoretically identical processes. Can this be explained by combining data
from tool producer and customer?
 How can benefit be realized when respecting the intellectual property of tool producer and customer?
