In order to keep and increase a competitive potential, industrial enterprises have to reduce their costs for product development as well as shorten lead time in product development processes. Moreover they have to respond to market factors and conditions such as increasing demands for functionality and individuality of products, short product life cycles, high pressure on prices and time to market. The improved functional requirement in connection with high time and cost pressure lead to high risk in product development. Technological fine improvements in connection with high time and cost pressure lead to high development risk. To cope with these challenges many enterprises have to collaborate globally. The collaborative engineering in product development is aimed to create distributed collaborative corporations and to facilitate the management of design conflicts. This paper provides a methodology for analyzing collaborative design process as well as the tools and the framework to support collaborative product development. The methodology can identify the interdependences among design tasks and teams. The tools and framework are implemented to facilitate the management of product development process.

In the paper we study the finite-time ruin probability in a general risk model with constant interest force, in which the claim sizes are pairwise quasi-asymptotically independent and arrive according to an arbitrary counting process, and the premium process is a general stochastic process. For the case that the claim-size distribution belongs to the consistent variation class, we obtain an asymptotic formula for the finite-time ruin probability, which holds uniformly for all time horizons varying in a relevant infinite interval. The obtained result also includes an asymptotic formula for the infinite-time ruin probability.

A vacation destination was conceptualized to be chosen through a three-stage process consisting of an early consideration set formation, a late consideration set formation, and a final selection stage. Choice criteria were defined as an individual's belief toward the relationships between perceived attributes, expected outcomes, and the destination. And these criteria were assumed to be divided into benefit-related dimension and perceived risk-related dimension. Through two pilot surveys, 13 items which have 4 factors were identified. used on 4 factor structures, the benefit-related dimension was identified to be consisted of three sub-dimensions, "historic/cultural", "escaped" and "naturalness". A longitudinal panel survey was used to test the differences of the importance of choice dimensions through the choice process. The importance of benefit-related dimension was decreased through the choice process as hypothesized except "naturalness" factor. And as hypothesized, the importance of perceived risk-related dimension was increased.

We consider a continuous time surplus process with investments the sizes of which are independent and identically distributed. It is assumed that an investment of the surplus to other business is made, if and only if the surplus reaches a given sufficient level. We establish an integro-differential equation for the distribution function of the surplus and solve the equation to obtain the moment generating function for the stationary distribution of the surplus. As a consequence, we obtain the first and second moments of the level of the surplus in an infinite horizon.

The purpose of this study is to verify the effect of the converted accident ratio on the contract of construction work. For doing the objective, this research analyzed the bid system and the converted accident ratio computation system in force. Additionally, we estimated what risk grades influence a successful bid of constuctin work. As a result of this study, we have recognized that the converted accident ratio scarcely has an effect on PQ process.

Purpose - This research mainly studied with the promotion of "one belt and one road "initiative's strategy and the construction of China, Japan and South Korea Free Trade Zone, China exports urgently needed industrial products to Japan and South Korea, which will not only help digest excess industrial capacity, optimize China's industrial structure, but also promote the economic development of Japan and South Korea. Research design, data, and Methodology - The study conducted a survey on 2018 year new revision of China-Korea Japan's data. Results -This study shows that In this process, multinational enterprises, as pioneers of economic development, play an irreplaceable role. However, due to the differences between laws of different countries and their own corporate culture concepts, enterprises in different countries will inevitably encounter various conflicts in the process of development. Conclusions -This requires our enterprises to have awareness of legal risk prevention in the process of development, and to study the corporate culture of relevant enterprises to truly achieve win-win cooperation.

The current facility condition monitoring has disadvantages such as a slow inspection cycle, a risk of human casualties, and the need for a lot of time and money as the size of the structure is larger, because human access is required with limited use. Drones can reduce the risk of human casualties due to their good accessibility, and can compensate for the shortcomings of the current method by enabling monitoring on a wide scale. The goal of this study is to provide the current domestic monitoring process through benchmarking according to the recent research case of the US Department of Transportation (DOT) to suggest a process suitable for the domestic situation and the direction of future improvement measures.

As a recent global trend, the majority of plant projects are delivered through EPC or EPC-turnkey contracts, where a contractor's liability is more complicated because of the mega size scale and financing method. Previous researches have been lacking a practical usability for project members for liabilities of contracts. Those were focused on solving the claims or schedule calculation issues only. The objective of the present study was to develop a validation process for LDs (liquidated damages) in contractor's liabilities with various case studies and expert judgments. As summarized in this paper, the processes and tools were developed with project life cycle process. The project preparation phase includes 3 step check lists to determine the Go or No-go for projects. In progress phase, contractors should focus on the response strategies for claims with liabilities. The study concludes that those developed processes and tools will help to manage risk of LDs for the contractors in the overseas projects.

미얀마는 아시아 국가 중 개발 가치가 높은 미개발 국가이다. 이에 미국을 비롯한 다양한 국가에서 시장 진출을 고려하고 있는 상황이다. 이러한 측면에서 부동산 개발 프로젝트의 수요는 외국인들의 유입 증가와 미얀마 경제성장에 따라 증가할 것으로 예측된다. 하지만 미얀마는 국가적 리스크를 포함해 해외 진출기업의 측면에서 위험도가 높은 국가이다. 이에 본 연구에서는 미얀마에 관한 자료분석을 실시해 리스크 유발요인을 추출한 후 전문가(법률, 금융, 기술, 현지 전문가) 심층인터뷰를 실시하였다. 이를 통해 106가지 리스크 요인을 추출하였으며, 친화도법을 활용해 3차에 걸친 그룹핑 작업을 실시하여 최종 리스크 분류 체계를 구축하였다. 그리고 AHP 기법을 활용해 각 요인별 상대적 중요도를 분석하여 제시하였다. 그 결과 해당 국가 관련 리스크, 자금 관련 리스크, 분양 관련 리스크의 중요도가 높게 나타났다. 본 연구결과는 미얀마 부동산 개발형사업의 진출기업에게 리스크관리 기준을 제공할 것으로 기대된다.

드론의 폭발적 수요 증가로 인하여 저고도 공역에서 운항하고 있는 기존 항공기 및 국가 중요시설 안전에 큰 위협을 초래하고 있다. 저고도 공역 드론 안전위협의 종류 및 정도를 판단하기 위하여 각 분야의 항공종사자를 대상으로 저고도 공역 운항시 드론으로 부터의 위협 종류 및 형태를 AHP (analysis hierachy process) 분석을 통하여 가중치를 평가하고자 한다. 드론으로부터의 위협요소 계층도 구성은 항공선진국인 유럽 항공안전기구 (EASA)에서 선행 연구된 특정 운영 위험평가 SORA(specific operation risk assessment process) 기법을 활용하여 설계하였다. 이를 바탕으로 각 항공기 운항 및 임무수행간 사전 위해요인을 식별 제거함으로써, 기존 항공기들의 저고도 안전 운항을 확보할 수 있을 것이다.
