Adoption of RFID has become widespread including logistics, drug supply-chain, and healthcare. To adopt RFID, we need to evaluate performance and feasibility of RFID S/W such as EPC Information Service (EPCIS), which demands a variety of test datasets of RFID business events. This paper proposes a novel method for creating RFID business events dataset by means of the simulation of RFID infrastructure. Proposed model provides a flexible representation capability since this is based on well-known petri-net. In addition, it can also be useful when determining adoption of RFID as it supports simulation of RFID environment.

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.

Agent technology has been widely applied in today's electronic business, such as mobile agents, multi-agent information systems, etc. In particular, multi-agent systems have been applied as powerful simulation tools to study complex business networks composed of various self-interested trading firms and/or human beings. In this paper, we build an integrated model that consists of a multi-agent B2C market model and a B2B trade network model, and incorporate more reality than much of prior work. Then with this model, we carry out experimental studies on two different strategies that are common in electronic business - 'loyal' strategy (retailers try to build stable cooperation with suppiers to ensure material supply) and 'cost-saving' strategy (retailers try to reduce cost by choosing suppliers with lower wholesale price).

본 논문에서는 기업의 기존 특허 포트폴리오를 비즈니스 모델 컴포넌트의 관점에서 사업타당성 평가를 수행할 수 있는 연구개발 비즈니스 모델링 및 시뮬레이션 시스템을 제안한다. 제안 시스템은 기업이 보유하고 있는 기존 특허들의 기술적 가치를 평가하는 것이 아니라, 비즈니스 모델의 9가지 컴포넌트 관점에서 특허가 보유하고 있는 비즈니스적 특징을 분석할 수 있는 시스템이다. 평가 모델은 4가지 세부 평가모델로 구성하였으며, 시뮬레이션을 수행할 수 있는 기본 파라미터와 제어 파라미터를 제공하여서 파라미터들의 값을 조정하면서 다양한 환경에서의 평가 결과값을 실시간으로 확인할 수 있도록 구현하였다.

팬덤 문화가 확산함에 따라 굿즈 구매량이 증가하였고, 동시에 포토카드를 탑로더에 넣어 꾸미는 '탑꾸'를 SNS에 자랑하는 문화가 형성되었다. 그러나 구매 전 꾸미기 재료를 미리 조합해 볼 수 없어 실제로 재료를 조합할 때 비용적, 시간적, 자원 소모 측면에서 문제점이 발생하고 있다. 현재 가상 세계가 발전하면서 현실에서 실현하기 어려웠던 것을 시도할 수 있게 되었고, 소비자들도 가상 세계에서 활발하게 교류하고 있다. 본 논문에서는 '메타버스를 활용한 꾸미기 시뮬레이션'을 개발하여 탑로더를 꾸밀 때 발생하는 시행착오를 줄이고 비용을 절감할 방안을 제시한다.

Decision makers in the service industry must effectively cope with queuing problems, service capacity optimization, service efficiency and service quality problems. This study proposes a computer simulation-enabled MCDM framework that integrates computer simulation analysis, Taguchi method, expert opinion and multiple criteria decision making (MCDM) to assist decision makers in coping with decision problems. In this framework, Taguchi method is adopted to reduce the time required for the simulation experiment. Computer simulation analysis is adopted to obtain useful information for rapid decision-making without interrupting actual production. MCDM is used to select the optimal alternative. The illustrative result is extremely promising.

Semiconductor wafer fabrication is a business of high capital investment and fast changing nature. To be competitive, the production in a fab needs to be effectively planned and scheduled starting from the ramping up phase, so that the business goals such as on-time delivery, high output volume and effective use of capital intensive equipment can be achieved. Project executed that use conveyor in bay semiconductor A line. But conveyor capability is lacking and rundown happened in equipment. Do design without normal simulation and conveyor system failed. The comparison is peformed through simulation using .AutoMod a window 98 based discrete system simulation software, as a tool for comparing performance of proposed layouts. In this research estimate optimum conveyor capability, there is the purpose.

Purpose - This study examines how consignment and Vendor-Managed Inventory perform as supply chain collaboration programs. By using three key collaborative features, this study defines the collaboration programs and develops theoretical models of different supply chain systems. Research design, data and methodology - This study conducts sophisticated analysis on the supply chain systems by applying simulation modeling based on time-phased operations. The simulation model represents a two-stage supply chain system where a supplier sells a single item to a buyer, and it incorporates various operations. Results - In general, the simulation outcomes support that more advanced collaboration programs outperform less advanced ones. The analysis on the simulation outcomes identifies the significant value of information sharing in both collaboration programs. The specific conditions where the particular collaboration system outperforms the others are recognized. Conclusions - The outcome of this study supports that the supply chain system can improve its performance by having more collaborative features. This study provides business practitioners with guidelines to identify the circumstances that the specific collaboration program can fully exploit its advantages.
