Of digital business models, platforms and gatekeepers - from analogous to digital business models 

Jun.-Prof. Dr. Benedikt Schnellbacher, 7/18

 

business model

1. Value offering architecture - value can be something that solve problems, satisfy something?
2. Internal value creation architecture
3. External value creation architecture
4. Financial architecture

 

business model innovation

• BMI(Business Model Innovation) comprises either innovating one core element or several of them 
• BMI can be realized with a subquent change
• …

 

Digitization - analog to digital stored information 

Digitalization - digital technologies

Digital Transformation - profound change

 

Drivers for value creation 

• Learning effects - google’s search algorithm
• Network effects - facebook(direct) and AirBnB(indirect)

 

Search Engine Market Share Worldwird - 6 2024

• Goggle 91.05
• Bing 3.74
• Yandex 1.44
• …

 

 

Two main challenges to value capturing in platform business models

1. Multihoming 

• When participants of both sides of the platform can easily switch between different platform providers

 

1. Disintermediation

• When users of a platform can easily bypass the network to connect directly
• example: Freelancing platforms
• approaches to solve it - AirBnB의 case: 유저가 결제하기 이전에 제공받는 정보를 제한

 

Five Characteristics of AI-powered networks

• made of digital connections between network nodes
• …

 

Strategic network analysis 

1. Mapping the networks - List the major networks a business is connected to (ex uber - drivers, riders/users)
2. Network value creation and capture factors
3. Mapping the company’s opportunities

 

Gatekeeping

information의 dissemination(바로 송출되지 않고, 필터링되는 것)

 

• Classic gatekeeper problem - T mobile, apple(hardware supplier), …
• Gatekeeper problem of the internet - technical infrastructure(broadband operators, hardware suppliers), software and data(search engines, social networks) google, facebook, …

General Introduction of the Institute

 

Dr.-Ing. Dominik Britz, 7/22

 

Research Focal Points

• Surface Engineering 
• Materials Engineering
• Advanced Microstructures

 

Machine Learning in Material Science 

Material Microstructure Classification에 AI 기술 사용 

 

• Consider ML in mc in holistic approach

 

Correlative Microscopy: LM + SEM + EBSD

 

Ground truth assignment - supervised learning

 -> unsupervised learning: EBSD data -> Demensional reduction(t-sne) -> Clustering(k-means)

 

PAG Segmentation

 

conclusion

• Controlling and understanding material science related aspects > optimization of ML hyperparameters

 

그래서 이걸로 뭘 할 수 있냐?

• Enhanced connectivity
• Optimized friction & wear 
• hygenic surfaces 
• security & optical design
