CrossFlow: Cross-Organizational Workflow Management in Dynamic Virtual Enterprises

Abstract: In this report, we present the approach to cross-organizational workflow management of the CrossFlow project. CrossFlow is a European research project aiming at the support of cross-organizational workflows in dynamic virtual enterprises. The cooperation in these virtual enterprises is based on dynamic service outsourcing specified in electronic contracts. Service enactment is performed by dynamically linking the workflow management infrastructures of the involved organizations. Extended service enactment support is provided in the form of cross-organizational transaction management and process control, advanced quality of service monitoring, and support for high-level flexibility in service enactment. CrossFlow technology is realized on top of a commercial workflow management platform and applied in two real-world scenarios in the contexts of a logistics and an insurance company.

Machine Learning Testing: Survey, Landscapes and Horizons

Abstract: This paper provides a comprehensive survey of Machine Learning Testing (ML testing) research. It covers 138 papers on testing properties (e.g., correctness, robustness, and fairness), testing components (e.g., the data, learning program, and framework), testing workflow (e.g., test generation and test evaluation), and application scenarios (e.g., autonomous driving, machine translation). The paper also analyses trends concerning datasets, research trends, and research focus, concluding with research challenges and promising research directions in machine learning testing.

Three Good Reasons for Using a Petri-Net-Based Workflow Management System

Abstract: Currently, the Dutch Customs Department is building a nationwide information system to handle all kinds of declarations related to the import and export of goods. For this purpose the Petri-net-based Workflow Management System (WFMS) named COSA has been selected. During the selection process, it turned out that there are several reasons for insisting on a Petri-net-based WFMS. The three main reasons for selecting a Petri-net-based WFMS are discussed in this paper. In our opinion these reasons are also relevant for many other projects involved in the selection or implementation of a WFMS.

Surface-Based 3D Modeling of Geological Structures

Abstract: Building a 3D geological model from field and subsurface data is a typical task in geological studies involving natural resource evaluation and hazard assessment. However, there is quite often a gap between research papers presenting case studies or specific innovations in 3D modeling and the objectives of a typical class in 3D structural modeling, as more and more is implemented at universities. In this paper, we present general procedures and guidelines to effectively build a structural model made of faults and horizons from typical sparse data. Then we describe a typical 3D structural modeling workflow based on triangulated surfaces. Our goal is not to replace software user guides, but to provide key concepts, principles, and procedures to be applied during geomodeling tasks, with a specific focus on quality control.
