The concept of lean production originated and was applied mainly to manufacture industries Even proven successful with such companies as Toyota, lean production has to be combined railway transportation production in order to bring its function into full play. The paper analyzes for applicability of lean production in railway transportation production organization, puts forward implementation methods such as transportation resource integration, station-zone organization, dispatch command optimization, railway performance evaluation index system, etc., and makes an exemplification study of lean production of Urumqi Railway Bureau in China, which testifies the applicability and efficiency of railway lean production.

Many of Korea major companies have appled as strategy of management innovation Six Sigma, Lean and Theory of Constraints. Six Sigma has mainly focused to reduce variation. Lean has mainly focused to reduce wastes and Theory of Constraints has mainly focused that bottleneck of constrains production and sales. This bottleneck is caused by constraint resources and it should be the main role of manager to explore constraint resource. Although their mainly focus are different, they are used to improve productivity and quality. In this paper, as strategy of management innovation, study on analysis and comparison plan of Six Sigma, Lean and Theory of Constraints. From the literature survey and application cases, it is suggested and discussed that how to plan of application as strategy of management innovation successfully. The suggested plan of application could be a good guideline that it could be a apply of companies.

린 건설이 건설업에서 생산성 향상을 위한 새로운 관리 방식으로 소개되어진 이후 많은 연구들이 린 건설의 성공적 실행을 위해 진행되어져 왔다. 현재 미국 내 건설회사들은 린 건설학회(LCI)에서 개발한 라스트플래너(LPS) 시스템을 현장에 적용해 보고 있으며 몇몇 현장은 성공적인 공사결과를 얻어내고 있어서 향후 린 건설의 도입 가능성을 보다 높이고 있다. 또한 그 결과로 많은 회사들이 다른 회사들이 어떻게 린 건설을 수행하고 있으며, 린 건설의 장단점은 무엇인지, 그리고 자신들의 회사에 적용 가능한 것이 무엇이 있는지에 대한 정보교환에 대한 관심이 높아지고 있다. 본 연구는 사례연구를 통해 린 건설이 얼마나 효과적이며 어느 정도까지 건설현장에 도입되어져 가고 있는지 알아보고자 함에 있었다. 하지만 이 논문에서는 4단계의 LPDS를 간략히 소개하고, 또 사례현장의 개별면담과 설문조사를 통해 얻은 결과를 비교 분석하여 소개하고자 한다. 마지막으로, 린 건설의 국내현장 도입을 위한 몇가지 제안을 .제시하고자 한다. 린 건설은 아직까지 기존의 관리체계의 틀에서 완전히 벗어나지 못하고 있으나 꾸준한 연구와 사례연구를 통해 언젠가는 새로운 공사관리 혁신의 주도 시스템으로 자리 잡을 수 있을 것이라 확신한다.

Proving the effect of lean construction has yet to be done for its staying poor basic building though there has been efforts and wants to introduce the theory and concept of lean construction in practical site. Therefore, we need to specify the methods of productivity improvement and construction process through various adaptations in the site. Also, to apply such improvement methods systematically, we need active participation of owners, contractors and supply chain members in relation to construction industry and are also require appropriate methods to adapt. At first, this study thinks over the techniques of lean construction that has been verified through studies carried before. For second, it selects the technique of lean construction with the practicality in the construction site. For third, it is aimed to make a manual of lean process management by the use of TACT and V.S.M. For fifth, it will show the method of management for repeated activity and develop a guide-line and procedure that applies the concept of work sequence and resource equalization to each phase of process management. At last, it will show methods of reflecting V.S.M. to improve and grasp the waste factor from the step of managing an activity process and develop the form to analyze the waste in construction site by mapping the value flow.

Lean 6 sigma has recently been used to describe a management system which combines lean management and 6 sigma. The marriage between Lean manufacturing and 6 sigma has proven to be a powerful tool for cutting waste and improving the organization operations. Time and quality are the most important metrics in improving any company's production and profit performance. lean 6 sigma is a management innovation for improving production efficiency, process quality, cost reduction, investment efficiency and customer's satisfaction. in this paper, Advanced cell line is builded the home appliance goods of the LCD TV final assembly line of domestic company line, training the multi-skilled man and controlling the production information system based on Lean 6 sigma.

The supply chain not only includes the manufacturer and suppliers, but also transporters, warehouses, retailers, and customers themselves. Within each organization, such as manufacturer, the supply chain includes all functions involved in filling a customer request. these functions include, but are not limited to, new product development, marketing, operation, distribution, finance, and customer service. Lean Supply chain coordination improves if all supplier of chain take actions that together increase total supply chain profits. To design of Modularity by the grouping supplier, the proposed method is to develop the most appropriate production system models in the Supply Chain Management which is necessity of the times and its importance. The objects of this study is development of model and cost analysis to the modular production system in Lean SCM. Introduction of modular production system in Lean SCM is effective in reducing the cost in processing, manufacturing, inventory holding, ordering, etc.

건설공사는 매우 다양한 요인들에 의해 영향을 받으며 생산 주체도 공정별로 다양해서 생산과정상에 많은 변이를 내재하고 있다. 그러나 현재의 공정관리는 결과위주의 관리 방식으로 작업의 상호연관성과 변이 발생을 충분히 고려하지 못하고 있어 많은 문제가 발생하고 있다. 린 건설은 현재의 공정관리방식의 한계를 인식하고 있으며 공정계획의 신뢰성 향상, 공정의 안정성 확보 건축 생산의 효용성 증진을 위한 새로운 관리기술로써 평가 되고 있다. 본 연구에서는 린 건설 이론을 기반으로 한 기법들을 실무적용가능성 측면에서 분석하여 VSM 및 TACT를 이용한 공정관리 기법의 현장적용성을 검토하였다.

Nowadays, globally high-grade companies have done their best for increasing their competitive power through a many kinds of method in incisive competition for making certain of a pacesetting position. Among the rest, Six Sigma have been the best methodology of improving process and have proven to be effective by the result of improving process in many of manufacturing business, however, it has not obtained excellent results in the transaction business. In transaction business, a $30\sim50%$ costs in total costs is generated by slow-speed working and reworking. The slow processes decrease the quality and increase the cost, which decreases customer satisfaction, and finally the income is decreased. All of them are so called wastes in processes. For this, adopting of lean six sigma methodology in process management can eliminate the wastes and reduce the variation. This study focuses on distribution with the domains like capacity, layout, amount of location, assignment of product, operation procedure and operation rule in order to improve these domains, we make a further application of eight analysis ways based on DMAIC method for improving operation of processes of distribution center as the third profit source. The goal of this study is to trace an approach that can easily adopt of Lean Six Sigma in operational management of distribution center by a kind of data, analysis method and template.

Many enterprises are looking for counterproposals to be survival through innovation activities and to be held on their continuous businesses for their business management environments nowadays. One of the innovation activities is an improvement of Loss and reinforcement of business structure through Lean, TPM. Another one is an improvement of these innovation activities and have achieved lots of outcomes (profits). But most these activities have been applied for only the industries in Automobile, Semiconductor, Aviation, Construction with large enter in Korea. And most of minor cable enterprises don't even try to import these innovation activities excluding some how the small and medium cable enterprise can import the LEAN / 6 Sigma activities effectively with some of sample in real small and medium cable company.

Today, many companies will be isolated in competition if they do not have competitive power to overcome quick change and big crisis of market. Nowadays, globally high-grade companies have done their best for increasing their competitive power through a many kinds of methods in keen competition for making of pacesetting position. This study focuses on distribution with the domains like capacity, layout, amount of location, assignment of product, operation procedure and operation rule in order to improve these domains, we make a further application of eight analysis ways based on DMAIC method for improving operation of processes of distribution center as the third profit source. The purpose of this study is to seek an approach that can easily adopt of Lean Six Sigma in operational management of distribution center by a kind of data, analysis method and template.
