This paper presents a new methodology for business process simulation modeling and analysis based on role-oriented modeling concept. The proposed methodology allows for tracking people and their roles affected by reengineering the business process. It enables one to analyze and evaluate not only work flow, but roles that are part of the flow. A simulator based on this methodology is developed to systematically construct simulation models and conduct simulations easily and efficiently.

This study evaluates the effect of structured debriefing for a business simulation game for university students. The program provides an authentic learning experience of real-world business management by allowing learners to make decisions related to R&D, marketing, production, and finance through a business simulation game, and check the results in real time. In 2022, University A and B each ran a business simulation game-based program as an extra-curricular activity. University A conducted a traditional instructor-led debriefing where the instructor explained the summarized process and results, while University B implemented a structured debriefing which had been developed based on Gibbs' and 3D models. To assess the effect of the structured debriefing compared to the traditional instructor-led debriefing, business knowledge and entrepreneurship competencies were measured three times. Repeated measures ANOVA was used to test for the differences between the two groups and to examine interaction effects between group and time. The structured debriefing group achieved statistically significantly higher academic scores than the traditional instructor-led debriefing group at the post-test and in 2 weeks. There was no statistically significant difference between the groups in terms of entrepreneurship competencies. There was no interaction effect between group and time, both in academic achievement and in entrepreneurship competencies. In conclusion, the simulation game-based program integrated with the structured debriefing session is more likely to have a stronger impact on academic achievement and its retention.

본 논문은 건설사업 프로세스를 모델링하고 자동화시키기 위해 개발된 핵심 기술을 제시한다. 비즈니스 프로세스 리엔지니어링 (Business Process Reengineering: BPR)과 비즈니스 프로세스 자동화 (Business Process Automation: BPA)는 건설사업관리에서 중요한 요소기술로 인식되어 왔다. 그러나 기존은 BPR 기법은 어떤 프로젝트를 조달하는 데 있어서 수천 개의 비즈니스 프로세스를 식별(identify), 문서화(document), 구현(implement), 실행(execute), 그리고 유지관리(maintain)하기위해 많은 노력이 필요하다. 그에 더해서 기존의 전사적 자원관리 시스템 (Enterprise Resource Planning: ERP)에 사용되어온 BPA 기술은 건설사업 프로세스 관리를 위한 효율적인 확장성 (혹은 범위성)을 제공하는 데 적합하지 않다. 워크플로와 객체기술(object technology)이 응용은 건설업계에 확장성이 있는 기업용 응용프로그램을 구축하는데 매우 효율적일 것이다. 본 논문은 건설사업 프로세스 자동화를 위한 기술들 및 방법론을 다음의 내용을 포함하여 제시한다. 1) 자동화된 건설관리 단위업무들이 캡슐화된 소프트웨어 부품으로 개발되는 방법. 2) 프로세스 모델링이 자동화된 건설관리 단위업무들을 마우스로 드래그-앤-드롭 (Dragging-and-Dropping)만하면 되도록 모델링 절차가 용이하게 된 방법. 3) 사업 요청들(business requests)을 발의하고 이러한 요철등에 상응하는프로세스 인스턴스(process instances: 프로세스 수행단계에서 실행된 프로세스)를 생성하는 방법, 그리고 4) 비즈니스 프로세스 인스턴스가 실시간 시뮬레이션 엔진(real-time simulation engine)을 기반으로 하는 워크플로 기술을 사용하여 실행되는 방법. 본 논문은 의도적으로 단순화한 건설장비 예약 및 취소 프로세스를 사례로 사용하여 어떻게 건설 사업 프로세스 자동화가 달성되었는지를 제시한다.

Organizational change projects such as Business Process Redisign (BPR) have been perceived to incur high risk due to their high management complexity, enterprise-wide impace, and steep project cost. This research intends to reduce such risk by developing a systematic process redesign methods, called Dynamic Process Modeling (DPM) method. DPM integrates the customer-oriented business process modeling technique with computerized visual simulation technique to promote better understanding of the target process and enable performance simulation of the proposed redesign alternatives prior to actual BPR implementations. For the cusstomer-oriented process modeling, we propose Dynamic-Event Process Chain (Dynamic-EPC) extending from the conceptual customer process model, Event-Process Chain (EPC). We compare DPM with four other implementation-level process modeling methods over eight criteria and demonstrate its effectiveness by applying it to the real-world hospital BPR case.

BPMS (Business Process Management Systems) is aninformation system that systematically supports designing, administrating, and improving the business processes. It can execute the business processes by assigning tasks to human or computer agents according to the predefined definitions of the processes. In this research we developed a task assignment algorithm that can maximize overall process efficiency under the limitation of agents' capacity. Since BPMS manipulates the formal and predictable business processes, we can analyze the processes using queuing theory to achieve overall process efficiency. We first transform the business processes into queuing network model in which the agents are considered as servers. After that, workloads of agents are calculated as server utilization and we can determine the task assignment policy by balancing the workloads. This will make the workloads of all agents be minimized, and the overall process efficiency is achieved in this way. Another application of the results can be capacity planning of agents in advance and business process optimization in reengineering context. We performed the simulation analysis to validate the results and also show the effectiveness of the algorithm by comparing with well known dispatching policies.

This paper presents an idea and framework to automate a full cycle business process management and re-engineering by integrating traditional business process management systems, process mining, data mining, machine learning, and simulation. We build our framework on the cloud-based platform such that various data sources can be incorporated. We design our systems to be extensible so that not only beneficial for practitioners of BPM, but also for researchers. Our framework can be used as a test bed for researchers without the complication of system integration. The automation of redesigning phase and selecting a baseline process model for deployment are the two main contributions of this study. In the redesigning phase, we deal with both the analysis of the existing process model and what-if analysis on how to improve the process at the same time, Additionally, improving a business process can be applied in a case by case basis that needs a lot of trial and error and huge data. In selecting the baseline process model, we need to compare many probable routes of business execution and calculate the most efficient one in respect to production cost and execution time. We also discuss the challenges and limitation of the framework, including the systems adoptability, technical difficulties and human factors.

Workflow Management System (WFMS) is a software system to support an efficient execution, control and management of complex business processes. Since traditional commercial systems mainly focus on automating processes, they don't have methods for enhancing the task performer's efficiency. In this paper, we propose a new method of executing business processes more efficiently in that a whole process is scheduled considering the degree of the participants' workload. The method allows managing the largest constraints among constituent resources of the process. We utilize DBR scheduling techniques to develop the method. We first consider the differences between workflow process models and DBR application models, and then develop the modified drum, buffer and rope. This leads us to develop WF-DBR (WorkFlow-DBR) that can control the proper size of the task performers' work list and arrival rate of process instances. Use of WF-DBR improves the efficiency of the whole process as well as the participants' working condition. We then carry out a set of simulation experiments and compare the effectiveness of our approach with that of scheduling techniques used in existing systems.

This paper purposes analyzing how task assignments influence on business process efficiency, and improving business process efficiency in Business Process Management (BPM) environments. For this purpose, task assignment is categorized into dynamic assignment and static assignment. Dynamic assignment binds a user to a task at process run-time, whereas static assignments assigns a task to a user at process build-time. So far, the influence of task assignment methods has not been studied. We, in this paper, analyze the business process efficiency using two different assigning rule, in terms of cycle time as a efficiency measure. The comparison result can provide a guideline for a company who wants to employ commercial BPM systems.

생산시스템의 시간과 비용 효율성을 개선하는 것은 경쟁 우위를 구축하고 경쟁적인 비즈니스 환경에서 수익성을 향상하는 중요한 수단 중 하나이다. 그 중에서도 CONWIP(constant work-in-process)과 DBR(drum-buffer-rope)방법은 생산 공정의 효율을 개선하는 데 널리 사용된다. 이 연구에서는 실제 단추 공장 생산 시스템의 시뮬레이션 모델을 개발했다. 연구 결과에 의하면, CONWIP과 DBR 생산시스템 모두 병목 공정의 대기 시간을 감소시키는 등 실제 생산시스템보다 나은 결과를 나타냈다. 시뮬레이션 모델 결과를 바탕으로 제안된 생산시스템을 적용함으로써, 실제의 제조 공정의 효율을 크게 향상시킬 수 있을 것으로 기대된다.
