The purpose at this study was to investigate how component factors at SCM affect the performance at textile and apparel firms in a competitive market. For the methodology at this study, the questionnaire was developed based upon the literature review. 150 questionnaires were distributed to the CEOs, CMOs, and experts who operate SCM in textile and apparel firms. The returned usable 85 were analyzed by SPSS10.0 with multiple regression analysis and Cronbach's Alpha for internal consistency and reliability. The performance at the textile and apparel firms that adopted SCM was affected by information system, partnership, and business environment in a descending order. For details, the performance of the textile and apparel firms that adopted SCM was affected by computerization, information sharing, CEO's concern, alliance, and support in a descending order.

We consider a reverse supply chain with a production facility and a recovery facility, and address the joint control of production and disposal decisions for sustainable operations. Demands are satisfied from on-hand inventory of serviceable products, replenished via manufacturing or remanufacturing. Sold products may be returned after usage and each returned product is disposed of or accepted for recovery. Accepted returned products are converted into serviceable products after remanufacturing process. Formulating the model as a Markov decision process, we characterized the structure of the optimal production and disposal policy as two monotone switching curves under a special condition. Three types of heuristic policies are presented and their performance is numerically compared.

Real-time supply chain environments based on RFID will be an important topic in future society; Nevertheless, adopting RFID in real industry SCM is still in its infancy. The aim of this paper is to develop the physical framework of a fully adopting RFID system from manufacturing to recycle phase and measure the effect. So, we built a simulation station with fully appling RFID and analyzed benefits with mathematic model. Then, specifying the advantages and improvement scheme for real industry limitations were suggested. This work concluded that fully appling RFID in SCM gives improvement of quality and service to both production and consumer.

This paper studies the effect of information quality level and customer demand on performance measures in a supply chain. The information quality level compares 2 types, the information levels of a customer demand and a lead time. The customer demand process follows a general auto-correlated AR(1) process without seasonality. In the AR(1) process, ${\sigma}$ indicates the degree of demand fluctuation and ${\rho}$ means the trend of customer demand. ANOVA tests using a 5% significance level are performed in SPSS to examine significant performance changes among various cases.

Future war needs a lot of changes for military organization. In this circumstance, it is importance the role of the Military Equipment Command Separation (MECS). In case of Korea Marine Corps, in spite of being MECS, Marine Corps has formed supply chain depended on Amy and Navy even it. Thus we proposed a new SCM of Marine Corps with Sense and Response concept. There are many problems and arguments to implement of new SCM. Therefore it is essential solving the problems but we don't know core problems and right solving directions. So, In this study, we present core problems deduction and selection of solving direction using TP(Thinking Process).

This study presents the empirical results of comparing several demand forecasting methods for Supply Chain Management(SCM). Adaptive exponential smoothing using change detection statistics (Jun) is compared with Trigg and Leach's adaptive methods and SAS time series forecasting systems using weekly SCM demand data. The results show that Jun's method is superior to others in terms of one-step-ahead forecast error and eight-step-ahead forecast error. Based on the results, we conclude that the forecasting performance of SCM solution can be improved by the proposed adaptive forecasting method.

This paper presents a production planning methodology for semiconductor manufacturing supply chain network with volatilities caused by uncertainties such as unstable demand and price. In order to take volatilities into account, we develop two approaches; 1) stochastic model with consideration of various cases and 2) deterministic model considering replanning cost, and propose efficient solution methods. Computational experiments show that the performance of the proposed method is superior to that of deterministic approach using various scenarios.

Until now, the traditional production models and logistics have developed a broader strategic approach called supply chain. However, there are some obstacles to apply industry practice because of unrealistic assumptions. The most serious of them is that they assume the lead times are integer multiples of the planning time grid. This assumption makes it difficult to express the processing and transportation lags correctly. Thus, in this paper, we propose a new methodology for the integrated production/distribution model having non-integer time lags using the concept of dynamic production function. In case that the time lags are integer or non-integer, the dynamic production function reflects well the situation under given environments. Experiments show that the proposed model can express the real system more accurately than the prior model can.
