This report examines the issue of designing an efficient production system by increasing several types of flexibility. Increasing manufacturing flexibility is a key strategy for efficiently improving market responsiveness in the face of uncertain market demand for final products. The manufacturing system comprises multiple plants, of which individual plants have multiple manufacturing lines that are designed to produce limited types of products in accordance with their size and materials. Imbalance in the workload occurs among plants as well as among manufacturing lines because of fluctuations in market demand for final products. Thereby, idleness of some manufacturing lines and longer lead times in some manufacturing lines occur as a result of the high workload. We clarify how these types of flexibility affect manufacturing performance by improving only one type of flexibility or by improving multiple types of flexibility simultaneously. The average lead time and the imbalance in workload are adopted as measures of manufacturing performance. Three types of manufacturing flexibility are interrelated: machine flexibility, routing flexibility, and process flexibility. Machine flexibility refers to the various types of operations that a machine can perform without requiring the prohibitive effort of switching from one order to another. Routing flexibility is the capability of processing a given set of part types using more than one line (alternative line) in the plant. Process flexibility results from being able to build different types of final products at the same plant.

본 연구의 목적은 공급사슬유연성(운영유연성, 물류유연성)과 경쟁우위전략(저원가, 고품질, 납기신속성)간의 관계를 실증적으로 규명하는 것이다. 이를 위해 공급사슬유연성(운영유연성, 물류유연성)과 경쟁우위전략(저원가, 고품질, 납기신속성) 간의 관계에 대한 모형을 구축하였다. 관련된 자료를 수집하기 위해 구미에 위치한 제조 기업에 종사하는 종업원들에게 500부의 설문지를 배포하였다. 수집된 자료들은 SPSS 18.0을 사용하여 기술적 분석, 신뢰성 분석, 요인분석, 상관관계분석, 다중회귀분석 등의 통계적 기법을 활용하였다. 연구결과 운영유연성은 저원가, 고품질전략에 긍정적인 영향을 미치는 것으로 확인되었으며, 물류유연성은 납기신속성 전략에 긍정적인 영향을 미치나, 운영 유연성은 납기신속성에, 물류유연성은 저원가, 고품질 전략에 유의한 영향을 미치지 못하는 것으로 확인되었다. 따라서 기업은 적용하는 공급사슬유연성과 경쟁우위전략과 적절한 조화를 통해 기업전략을 극대화 할 수 있을 것으로 기대된다.

This paper explores a rational investment decision model in sequential capital allocation process under capital rationing. A method is proposed for measuring the new investment decision factor which is the flexibility that describes the future availability of invested funds. This flexibility is important in sequential decision process. Also presented is a multiobjective (MO) decision model into which flexibility is incorporated with the profit and risk factors. The effectiveness of this criterion is compared with the expected present value and the mean-semivariance criteria through a simulation model.

Flexibility is a competitive weapon in the changing environment. In order to pursue the flexibility, Korean manufacturing companies must define the flexibility dimension clearly, build the appropriate manufacturing infrastructures and measure the right flexibility performance indicators. This paper found out as follows. First, Korean manufacturing companies' flexibility strategy groups were formed three types. They are flexibility superior group, middle flexibility group and flexibility inferior group. Second, when different types of flexibility strategy group measured their performances, the degree of importance of flexibility performance indicators were different among groups. Third, when different types of flexibility strategy group were pursued, the different manufacturing methods such as product/process design technology, analysis technology, production system management technology and non technological factors were used. Lastly, when different types of flexibility strategy group were pursued, the actual flexibility performances were different among groups.

The purpose of this study is to investigate the conception and developmental process of stretching in sports physical therapy. This study is to find conception of stretching, feature and effect, principles and fundamental rule, consideration of enforcement and developmental process in order to use the basic material which is very helpful in the every field and the scene of sports needing stretching. Flexibility is the ability to move muscles and joints through their full ranges of motion. Flexibility is developed by stretching. About player who insufficiency of flexibility, patient and disabled person who restrict of range of motion, older adult who reduce of flexibility, promote of flexibility for upgrading stability and efficiency of body on the based of scientific principles is completed by stretching. The method of stretching has been developed with passive stretching, CR, PNF stretching, PIC stretching, MET stretching in the order. The effects that we can get through stretching are as follows : 1. Enhance physical fitness. 2. Optimize learning, practice and performance of many types of skilled movement. 3. Increase mental and physical relaxation. 4. Promote development of body awareness. 5. Reduce risk of joint sprain or muscle strain. 6. Reduce risk of back problem. 7 Reduce muscular soreness. 8. Reduce the severity of painful menstruation for female athletes. 9. Reduce muscular tension. 10. Advance recognition of body.

This paper is designed to characterize the concept of flexibility of mind and analyze relationship between flexibility of mind and divergent thinking in view of mathematical problem solving. This study shows that flexibility of mind is characterized by two constructs, ability to overcome fixed mind in stage of problem understanding and ability to shift a viewpoint in stage of problem solving process, Through the analysis of writing test, we come to the conclusion that students who overcome fixed mind surpass others in divergent thinking and so do students who are able to shift a viewpoint.

As productions and deliveries of multiple products to multiple marketplaces have been increasingly popular, supply chain flexibility, which refers to an ability to deal with demand and capacity uncertainty, becomes an important issue in supply chain management. However, logistics costs have been largely neglected in the literature on supply chain flexibility structure. In this paper, we propose mathematical models to investigate the impact of the logistics costs on the optimal flexibility structure. We also conduct a simulation study and observe that logistics costs have a significant impact on the decision on supply chain flexibility structure. Such conclusion is also supported by the case study of a global car manufacturer, Honda Motors.

Recent demographic changes have increased the heterogeneity of user groups in the housing market. Smaller households(e.g. elderly, single parent) have non-traditional spatial requirements that cannot be accommodated within the conventional house layout. This has created renewed interest in Demountable/Flexible housing systems. However, the process by which designers decide which project or user groups are most suited for the use of these systems is quite often complex, uncertain and dynamic, since the decisions involve natural processes and human values that are apparently random. This study is a proposal on the design process model for the flexibility of apartment.

In sequential capital allocation processes, the information on the future availability (flexibility) of invested funds provides a decision maker with additional insight into the characteristics of alternatives. The investment decision with consideration of flexibility and profitability results in more wealth accumulation than the decision without considering flexibility does in sequential investment processes. To utilize the information on the flexibility under certainty, the PV/FI decision model is developed.

This paper presents a new approach to managing dynamic business process changes based on business process change patterns. We identify and categorize business process change patterns that occur recurrently in a dynamic business environment. Several issues regarding management of process versions are discussed, and a pattern-based version management method for handling process changes more flexibly is explained in detail. We propose a mechanism for abstract process execution with runtime encapsulation of a business process, which can maximize the flexibility of process execution using multiple process versions. In addition, we propose a concept of process promotion and demotion that can dynamically choose an actual version of the process at run-time. With our pattern-based process change management and versioning approach, it is expected that the flexibility and efficiency of BPM systems can be enhanced significantly.
