During last ten years, logistics network management has become one of the most important sources of competitive advantage regarding logistics cost and customer service in numerous business segments. The key to success in this dynamic and severe business environment is the ability to design and plan the logistics network optimally in an integrated way. Network design and planning involves many issues relating to strategic, tactical, and operational decisions. To assist a logistics designer or planner, many computer-based decision support systems (DSS) have been developed. In this paper, the issues related to design, development, and implementation of the DSS for logistics network design and planning are discussed, and an ideal framework of the DSS is proposed with some ideas on the future development. Finally, DLNET, the DSS developed by author, is briefly introduced.

With the advent of the era of the 4th Industrial Revolution, various support policies and programs are being introduced as the promotion of startups related to the 4th industry is promoted as a core policy of the government. Based on major technologies such as Artificial Intelligence(AI), Big Data, Internet of Things(IoT), Blockchain, and Automation leading the 4th industrial revolution, logistics and distribution companies are expanding the range of markets and services provided. The purpose of this study is to examine the current status of startups in the logistics field based on major technologies of the 4th Industrial Revolution, which are rapidly growing at home and abroad, and suggest implications for revitalizing logistics startups through a policy demand survey. As a result of the study, in order to foster domestic logistics startups, we propose policy support for integration of logistics startups, integrated management of information, provision of physical space, network platform, and practical education and mentoring.

The business process of global third party logistics company is defined as a network of logistics activities which involves the products that are manufactured in the developing countries, such as Vietnam, China and so on, and delivered to North or South American countries via intermediate stopover sites. The third party logistics company usually uses proprietary logistics information system to support the related logistics activities. However, each consignor sometimes may require different business process based on the customer type or characteristics of their products. Therefore, the third party logistics company need to modify their business process to reflect customer's requirements, resulting in the modification of logistic information systems and additional costs. Therefore, a flexible mechanism is required to efficiently support the various types of requirements by the owners of the products. In this paper, first, we figured out various business rules related to third party global logistics activities. Second, we grouped the identified business rules into business processes, objects, relations, dependency, policy, representations, execution, and resources and further into precondition, postcondition, and invariant based on checking point in time. Furthermore, the categorized rules are classified into inter-activity and intra-activity rules based on the execution range. Third, we proposed a rule syntax to describe the defined rules into scripts which are understood by user and information system together. When each activity is executed, the rule manager checks whether there are rules related with the activity execution. Finally, we developed a prototype rule management system to show the feasibility of our proposed methodology and to validate it with an example.

물류분야에서 RFID 기술의 응용이 확산되면서 RFID 도입 요인과 물류성과와의 관계를 분석할 필요가 있다. 기존 여러 분야의 선행연구를 통하여 RFID 도입이나 채택에 영향을 미치는 요인을 도출하고, 물류기업을 대상으로 이러한 요인이 물류성과에 미치는 영향을 실증적으로 분석하고, 그에 대한 시사점을 제시하고자 하였다. 관련 선행연구에서 물류기업이 RFID를 도입하는데 있어 CEO 지원, 기술 우위성, 거래 파트너, 상호 양립성 및 상대적 이익과 같은 요인이 물류성과에 영향을 미치는 것으로 나타났다. SCM, 물류 및 유통, 제조분야를 대상으로 한 선행연구를 기초로 연구모형 및 가설을 설정하고, 물류기업 종사자를 대상으로 RFID 도입 요인이 물류성과에 어떠한 영향을 미치는지 설문조사를 실시하였으며, 탐색적 요인분석, 신뢰성 분석, 확인적 요인분석 및 구조방정식모형 분석을 통해 가설을 검증하였다. 연구 결과, CEO 지원과 거래 파트너의 RFID 도입 요인은 물류성과에 유의한 정(+)의 영향을 미쳤으며, 상호 양립성과 상대적 이익은 유의한 영향을 미치지 못하였다. 기술 우위성은 물류성과에 통계적으로 유의한 영향을 미치지 못하는 것으로 나타났으나 p=0.052라는 것을 고려할 때, 물류성과에 유의한 영향을 미칠 수 있을 것으로 사료되며, 유의수준 0.1에서는 유의한 영향을 미치는 것으로 나타났다.

물류서비스는 경제주체간의 원활한 상품 수송을 도모하여 구매, 소비를 뒷받침하는 효율적 경제 및 시장의 필수조건이다. 특히 기업의 물류활동은 소비자에게 전달하고자하는 제품 및 서비스의 생산과 유통을 책임지는 필수 기업활동이자 기업 경쟁력의 원천이다. 그러나 국내 물류기업의 영세성 및 낮은 생산성, 물류산업체계의 비효율성, 2자 물류기업 중심으로 성장하면서 비롯된 전문 제3자 물류 전문시장의 성장 한계, 물류기업의 해외진출 미흡, 물류 전문인력 부족 등이 해결해야 할 과제이다. 따라서 본 연구는 제3자 물류업의 개념과 발전과정을 살펴보고, 국내 제3자 물류업 시장 현황을 분석하여 이를 근거로 수요측면 즉 기업측면, 공급측면, 정부의 정책적 지원측면으로 구분하여 국내 제3자 물류업의 활성화 방안을 제시하였다.

본 논문은 우리나라 항공화물 상용화주제도의 활성화를 위해 물류정책 및 제도를 알아봄으로서 일반화주의 상용화주 전환 및 확대에 필요한 제도 활용을 제안하는데 목적이 있다. 2012년에 "항공안전 및 보안에 관한 법률" 및 2011년 "상용화주 항공화물 보안기준"이 개정되었으나 그 목적이 항공안전과 보안, 항공화물의 보안통제 절차를 규정한 것이어서 상용화주제 활성화 방안은 포함되어 있지 않다. 따라서 상용화주제 활성화를 위하여 2012년 개정된 "물류정책기본법"의 물류보안 지원제도와 물류공동화 제도, 컨설팅 지원에 대한 활용방안을 제안한다.

Logistics is by no means a new subject area. The concept of logistics goes way become more complex as technology advances, and logistics requirements have increased accordingly. In 1964, when ILS philosophy formally came into being, ILS was defined in general terms and did not describe what actions an ILS program should accomplish. ILS philosophy have been developed from 1964 through 1980. In 1982, United States Department of Defense formulated a new concept, CALS. CALS is the strategy that the US defense development to management the transition to integration and automated interchange in defense system engineering, manufacturing, and logistic support. Its goal is to use the inherent features of digitized data to revolutionize the function of data -gathering, data storage and data - transfer techologies associared with the development of defense systems. The Result will be systems that are cheaper, more reliable, and easier to maintain. To define CALS's character, the purpose of this papers compare two concepts - CALS and ILS. The elements of CALS consist of standads and EDI. The elements of ILS include LCC(Life Cycle Cost), LSA(Logistics Support Analysis), LSAR(Logistics Support Analysis Rcord), Aquisition Cycle.

Generally the life-cycle cost of complex systems composed of several sub systems or equipments such as train, aircraft weapon systems is spent much more during operation and maintenance phase than development phase. The maintenance cost for maintaining the availability and extending the life span of systems comprise a large proportion of systems operation cost. The cycle of preventive maintenance affects operation and maintenance cost a lot. In this study we introduce a way minimizing life-cycle cost of systems by calculating more reliable preventive maintenance period than the results of previous study using systems reliability data considered the reliability and failure effect ratio of sub-systems or components. We can solve the preventive maintenance period problem known as NP-Hard as quick as possible by using modified genetic algorithm than using other models introduced in previous study.

The configuration such as series, parallel and k-out-of-n of a repairable system directly affects its reliability. The maintenance strategy can also affect the overall performance of the system. The objective of this work is to investigate the possible trade-off between the configuration of a repairable k-out-of-n system and its maintenance strategy. The redundancy is considered to be the design decision variables, whereas the preventive maintenance period is considered to be the maintenance decision variables. The optimization model is used to minimize the overall life cycle cost associated with the system, considering constraint on reliability. Finally, genetic algorithm is used to find the optimal values for the decision variables. The result is compared with optimal values for considering redundancy and maintenance respectively.

미국은 2000년대 초반부터 무기체계의 전투준비태세를 유지하면서 수명주기비용을 줄이기 위해서 TLCSM를 적용하였다. TLCSM이 적용되면서 획득단계 중심의 ILS 개념에서 전체 수명주기 동안 수명주기비용을 관리하는 개념인 IPS로 전환하였다. 또한 ILS를 개발하기 위한 LSAR은 IPS을 개발하기 위한 LPD로 전환하였다. 본 연구에서는 한국의 LSAR과 미국의 LPD를 비교 및 분석하여 LPD의 한국 도입 시 필요한 정책을 제안하였다.
