To cope with rapidly changing enterprise environment, many business entities introduce EAI, which integrates applications by installing middleware. But existing EAI has a serious problem that is to import imddleware-dependent coding method to integrate systems, using different middlewares. In this paper, we suggest middleware independent 'Workflow Management System' which efficiently integrates applications of various middleware systems with 'Duplicate EAI Adapter', 'state chart' and 'XML' technology.

An evaluation demand and a market growth regarding evaluation and certification are increasing because the importance of information Security is gradually rising to solve the information disfunction. Therefore, it is necessary the cost-effect evaluation management of the Information Security System(ISS). In this paper, we propose the Semi-automated Evaluation Workflow Management System(Sa-EWMS) based on the Common Criteria(CC) which performs and manages evaluation work through the procedure when evaluator evaluates the Information Security System(ISS). The Sa-EWMS is solving a problem of consumption of time and effort and performing efficient evaluation, it is playing a significant role that traces workflow process of each work of the Engines and controls performance. It will be able to use useful the private evaluation enterprise which confront in an evaluation demand and a market growth.

The primary tasks of a workflow management system specify workflow models with respect to resource, control-flow, data-flow, functional, and operational perspectives, and to enact their workcases (workflow instances). In terms of enacting workflow models, the essential criterion grading the quality of the system is "how much is the system able to guarantee the correctness of workflow models' enactment?". Particularly, the workflow determinacy problem, which may be caused by the interference of the control-flow and the data-flow specifications, is the most challenging issue in guaranteeing the correctness of the system. We are able to solve the problem by either of the following two approaches-analysis of workflow model and verification of workflow enactment. In the paper, we propose a technique that guarantee the system's correctness through verifying workflow enactment. In other words, the technique is able to detect the conflicts of control-flow and data-flow enactments existing on a workflow model, which causes the system to be non-determinant in enacting workflow models. Finally, by applying the technique to the e-Chautauque workflow management system developed by the authors' research group, we prove that the technique is a feasible solution for the workflow determinacy problem.

This paper presents the core technology of Construction Business Process Automation to model and automate construction business processes. Business Process Reengineering (BPR) and Automation (BPA) have been recognized as one of the important aspects in construction business management. However, BPR requires a lot of efforts to identify, document, implement, execute, maintain, and keep track thousands of business processes to deliver a project. Moreover, existing BPA technologies used in existing Enterprise Resource Planning (ERP) systems do not lend themselves to effective scalability for construction business process management. Application of Workflow and Object Technologies would be quite effective in implementing a scalable enterprise application for construction community. This paper present the technologies and methodologies for automating construction business processes by addressing how: 1) Automated construction management tasks are developed as software components, 2) The process modeling is facilitated by dragging-and dropping task components in a network, 3) Raising business requests and instantiating corresponding process instances are delivered, and 4) Business process instances are executed by using workflow technology based on real-time simulation engine. This paper presents how the construction business process automation is achieved by using equipment reservation and cancellation processes simplified intentionally.

In programming classes, there is always a need to efficiently manage programming assignments. This is especially important as class sizes and assignment complexity grows. GitHub and GitHub Classroom makes the management of student assignments much simpler than uploading files and folders to a LMS or shared online drive. Additionally, git and GitHub are industry standard tools, so introducing students these tools in class provides them a good opportunity to start learning about how software is developed in the real-world. This study describes a workflow that uses both GitHub Pages and GitHub Classroom for more efficient classroom and assignment management. The workflow outlined in this study was used in two practical web programming classes in Spring 2023 with 46 third and fourth-year university students. GitHub Pages was used as a classroom website to distribute class announcements, assignments, lecture slides, study guides, and exams. GitHub Classroom was used as a class roster and assignment management platform. The workflow presented in this study is expected to assist other lecturers with the formidable tasks of distributing, collecting, grading, and leaving feedback on multiple students' multi-file programming assignments in practical programming classes.

Recently, many organizations such as companies or institutions have demanded induction of very large-scale workflow management system in order to process a large number of business-instances. Workflow-related vendors have focused on physical extension of workflow engines based on device-level clustering, so as to provide very large-scale workflow services. Performance improvement of workflow engine by simple physical-connection among computer systems which don't consider logical-level software architecture lead to wastes of time and cost for construction of very large-scale workflow service environment. In this paper, we propose methodology for performance improvement based on logical software architectures of workflow engine. We also evaluate scalable performance between workflow engines using the activity instance based architecture and workcase based architecture, our proposed architecture. Through analysis of this test's result, we can observe that software architectures to be applied on a workflow engine have an effect on scalable performance.

In this study, we investigate several problems of previous workflow system, and suggest an enhanced process management system that involves a substantial portion of workflow system. To overcome the differences in systems, we selected a web as platform to develop a process management system, and we investigate merit and capability of web-based process management system. We improved WFMS's ability to define various process through many behavior rules and multiple layered process structure. We suggest X-WPM system for the process management system with XML technology.

Workflow composition and management is a crucial part of Component Based Development (CBD). Workflows can be composed reusing existing workflows to improve efficiency during the various stages of software development process. Reusability of software process activities is improved by using existing workflows. This paper proposes a Workflow Composition Engine that generates workflow which consists of existing process activities and describes design of The Workflow Composition Engine. A prototype of the Workflow Composition Engine implemented is described.

Many enterprises have introduced workflow to enhance work efficiency and support effective work processes in their various work environments. Recently, Business Process Management(BPM), an extension of workflow, is spotlighted in enterprise software markets Although woklflow plays an important role in Business Process Managements, researches in workflow are mostly concentrated on temporal constraints which finds exact execution sequences for complicated jobs. On that reason, majority of workflow scheduling has concentrated on modeling of various resources which should be handled and the interest for workflow scheduling under constraints related to resources is rather unsatisfactory In this paper we presents the Transformation Template based on Concurrent Transaction Logic(CTR) which is suitable for scheduling workflows with resource allocation constraints, and the logical framework. The Transformation Template consists of a Workflow Transformation Template and a Constraint Transaction Template. Especially the Transformation Template can be conveniently used to logically represent new workflows under the existing resource allocation constraints.
