Project title: Development of eXplainable AI Framework for Process Predictive Monitoring (2022. 06. 01 ~ 2025. 02. 28)

프로세스 예측 모니터링용 eXplainable AI 프레임워크 개발

  • The project’s application domain is process mining, ie, the application of data science techniques to event logs collected from information systems during the execution of business processes. The objective of process mining is to improve the efficiency and effectiveness of business processes. Within process mining, this project focuses on predictive process monitoring (PPM), which deals with the application of machine learning techniques for the prediction of aspects of interests of the future process execution, based on the historic data collected about the process execution. Within PPM, the specific focus of the project of this project is to develop new methods for (i) supporting the explainability of predictions in PPM applications and (ii) providing support to the automated generation and fine-tuning of PPM models, ie, AutoML forPPM. This research project consists of a total of three parts (years), from (1) design of the XAI framework for process prediction monitoring, (2) development of algorithms, (3) evaluation of practicality and reliability through expert panel evaluation, and implementation of integration with commercial process mining tools.

Project title : Development of a platform for process mining in port logistics (2019.05 ~ )

-빅데이터 기반 컨테이너 터미널 혼잡도·수출입 물동량 예측 시스템을 활용한 항만물류 최적화 서비스 개발

  • Company : Ulsan Port Authority
  • The objective of this project is to develop a platform for process mining in port logistics. While, in fact, process mining has been extensively applied in domains such as health care and public administration, applications of process mining in logistics and, particularly, port logistics, remain limited. This implies that the logistic industry is lagging behind on the potential savings and operational improvements normally accrued by the application of process mining techniques in real world settings. Therefore, a thorough analysis of the potential of process mining applied to the analysis of port logistics data is needed. This platform aims at identifying critical aspects concerning event log collection and analysis in (port) logistics, critical use cases of process mining in different reference business processes in (port) logistics, and demonstrating the effectiveness of different process mining techniques using real world port logistics data publicly available and, possibly, collected from Ulsan Port Authority (UPA). As far as process mining techniques are concerned, the focus will be mainly on predictive process monitoring techniques, an emerging branch of process mining that aims at adapting data mining techniques for predicting aspects of interests in business processes using event log data.

Project title : Blockchain-based System Engineering (2018.01 ~ 2019.12)

  • UNIST Research Find (Excellent research idea discovery project)
  • Although blockcain is recognised as a potentially disruptive technology for all industries, deployment of blockchain-based solutions outside finance and, specifically, cryptocurrencies and related applications, is still largely experimental. This is particularly true when blockchain is seen as a tool for engineering information exchange among a set of collaborating parties, or a “business network”. Many emerging applications are showing that there are a variety of design choices available while (re-)engineering a system using blockchain, such as the size and content of blocks, consensus rules to create new blocks, or the nature and shape of the smart contracts to be embedded in blocks. However, a scientific approach to exhaustively identify these design choices and guide designers during implementations is currently lacking.
    This project aims at filling this gap, by devising a methodology for reengineering systems using the blockchain technology. This methodology will comprise an analysis of the blockchain-based system design space, ie., the set of design choices available to designers, and a set of guidelines to support designers of a system during implementation.

Project title : Blockchain Platform with Business Models towards Cross-domain Interoperability (2018.06 ~ 2020.02)

-크로스 도메인 호환성을 위한 블록체인 플랫폼 및 비즈니스 개발

 

  • IBRC POSTECH (대학ICT연구센터육성지원사업)
  • The Intelligent Enterprise Lab at UNIST, chaired by Prof Marco Comuzzi, conducts research in the areas of enterprise systems, business process management and blockchain-based systems design. The Lab has received a seed funding from UNIST for the year 2018 to develop a methodology for blockchain-based system design using case studies of real blockchain-based application development in the UNIST campus. The expertise developed within this seed funding research will constitute fundamental background knowledge for the research to be conducted in this project. In particular, the developed methodology will be extended to the case of interoperability of multiple blockchains. The Lab research in business process management also contributes to build important background knowledge for this project. Prof Comuzzi has a strong track record at UNIST and his previous research in the area of cross-organisational business process management modelling and enactment. This project represents an opportunity to transfer this knowledge into the context of blcockhain-based system interoperability design and enactment.

  • Company : TAE SUNG ENVIRONMENT INSTITUTE
  • The project objectives of this project are to be compressed into the following three. (1) Establish a big data integration platform related to odor. (2) Development of artificial intelligence for odor analysis. (3) Design of Ulsan Metropolitan City Odor Monitoring Service System based on Artificial Intelligence. Among them, the pure research goal excluding the platform and the design part of the system is related to the second business objective ‘deodorization artificial intelligence development’. Specifically, it is necessary to develop a high-performance odor recognition artificial intelligence model by identifying and solving various problems arising in the data collection-processing-analysis stage through the repeated experiment process of applying and testing various algorithms on odor data. It is a goal.
