By analyzing five in-depth case studies of suppliers in newly emerging Vietnam's motorcycle industry, this paper explores the differences in patterns and processes of capability improvement of suppliers who participate in different kinds of supplier-assembler network with different structures. The paper finds the correlation between the kinds of suppliers' capabilities improved and the structure of networks they participate in. While suppliers in arm-length networks can improve more upstream capabilities (structure design, process desist), suppliers in embedded networks can improve more downstream capabilities (process design, process setup, process maintenance and delivery control). Two capability improvement patterns of firms in newly emerging economy are indicated. The first pattern is asymmetrical improvement, either upstream or downstream capabilities, by participating in either arm-length or embedded networks. This pattern obstructs the suppliers to meet the requirements of new buyers rho come from different kinds of network. The second pattern is symmetrical improvement by joining both arm-length and embedded networks.

With the growing interest in pet dogs and pet dog's wear I used this study to compare and analyze the pattern used by each supplier and developed a new pattern for pet dogs' wear which is appropriate for pet dogs' body lines and movement. Test subjects were 91 pet dogs in Busan and after comparing 3 patterns from different suppliers, I developed the pattern reflecting pet dogs' body shapes and movement. Results are as follows; 1) As a result of analyzing measurements, it was found that pet dogs motion in walking on four feet, is different from that of people on two feet. For center measurements, their waist to bust length is longer than their waist to back length. The result of analysis shows that bust circumference impacts most other measurement results and it seems that better results are achieved if the bust line is taken into consideration when measuring bust back length, bust front length, neck base circumference, front leg arc, the length between lateral shoulder etc. 2) As a result of comparing suppliers' patterns, it was discovered that each supplier has different sizes for the same patterns and those sizes are not standardized across the board. Even if the same size of pattern was actually used in the production of pet dogs' wear by the individual companies, there were many variations in size for each item. 3) To develop a more standard pattern of pet dogs' wear, I collected and analyzed 3 patterns from each supplier and designed a new pattern, revising it three times. After test-wearing of the experimental pattern and the studied patterns, and comparing and analyzing the results, the studied pattern had similarly better estimation than the experimental one.

The purpose of this paper is to study the pattern of interactive learning in strategic networks. Interactive learning is defined as the exchange and sharing of knowledge resources conducive to innovation between an innovator firm, its suppliers, and/or its customers. The strength of internal knowledge resources can either hamper or facilitate levels of interactive learning. We assume that more complex innovative activities urge firms to co-ordinate and exchange information between users and producers, which implies a higher level of interactive learning. To test our theoretical claims, we estimated the level of interactive learning of firms in strategic networks with: (1) their customers, (2) their suppliers. Theses analyses allow a comparison of the antecedents of interactive learning of firms participating in strategic networks. Our findings suggest that interactive learning with customers is positively affected by company's capabilities and value-created activities, and with supplies is positively affected by value-created activities and technology innovation centers.

We analyze a transaction mechanism so-called the revenue sharing transaction model and its dynamics in a supply chain with two competing suppliers and a monopolistic retailer when the demand pattern is uncertain and the back-order is allowed in case. We assume that the products by the suppliers are substitutable each other with a certain degree even though their retail prices are different. It is proved that a supplier and the retailer in the supply chain have some room for enjoying the possibility of their increased profits comparing with the present ones by adopting the suggested revenue sharing scheme. Furthermore, such a transaction model is beneficial even to the customers by offering a lower retail price than before. On the contrary, we observe that another supplier which sticks to an existing transaction scheme is supposed to suffer some decrease in its profit as a result.

In this paper, we deal with an inventory model of a multi-stage, serial supply chain system where a single product type and nonstationary customer demand pattern are considered. The retailer and suppliers place their orders according to an echelon-stock based replenishment control policy. We assume that the suppliers can access online information on the demand history and use this information when making their replenishment decisions. Using a reinforcement learning technique, the inventory control parameters are designed to adaptively change as the customer demand pattern is altered, in order to maintain a given target service level. Through a simulation based experiment, we verified that our approach is good for maintaining the target service level.

The efficiency of a supply chain can be extremely affected by its design which includes determining the flow pattern of material from suppliers to costumers, selecting the suppliers, and defining the opened facilities in network. In this paper, a multi-objective multi-echelon multi-product supply chain design model is proposed in which several suppliers, several manufacturers, several distribution centers as different stages of supply chain cooperate with each other to satisfy various costumers' demands. The multi-objectives of this model which considered simultaneously are 1-minimize the total cost of supply chain including production cost, transportation cost, shortage cost, and costs of opening a facility, 2-minimize the transportation time from suppliers to costumers, and 3-maximize the service level of the system by minimizing the maximum level of shortages. To configure this model a graph theoretic approach is used by considering channels among each two facilities as links and each facility as the nodes in this configuration. Based on complexity of the proposed model a multi-objective Pareto-based vibration damping optimization (VDO) algorithm is applied to solve the model and finally non-dominated sorting genetic algorithm (NSGA-II) is also applied to evaluate the performance of MOVDO. The results indicated the effectiveness of the proposed MOVDO to solve the model.

The purpose of this study is to survey and analyze the general conditions of infants' apparel brands in Korea, review the sizes and specifications of each brand, analyze the differences and correlations among brands, and thereby, present the reasonable sizes and specifications for infants' apparels in consideration of domestic and foreign specifications and infants' health conditions. for this purpose, 13 brands manufacturing the apparels for the infants aged from 0 to 4 were sampled, and their design directors and outside pattern suppliers were surveyed through direct interviews. The collected data were processed for frequencies, mean, median and mode. The results of this study can be summarized as follows; 1. The sample infants' apparel brands were mostly launched as national brands in 1990's, while their target ages were diverse : 0 $\sim$ 72 months, 0 $\sim$ 36 months, 0 $\sim$ 48 months, 0 $\sim$ 60 months, 12 $\sim$ 24 months, etc. 2. More brands were restructuring the pattern suppliers' sizes and specifications rather than developing them directly, which suggests that most of infants' brands depend much on pattern suppliers. 3. Infants' apparel brands were presenting the 'space suites' sized from #60 to #90 because consumers prefer those space suites distinct in their upper and lower parts and convenient for their toddlers aged 36 months or older. The brands were setting the sizes for 6 parts: total length, breast, sleeve length, hip, hip height, leg. 4. The sizes for infants' one-pieces were #70, #75, #80, #85, #90, #95, #100, #110 and #120, while their subsizes were determined for 4 parts: total length, breast, sleeve length, hip.

The purposes of this study were to investigate the difference of the SCM activities in the general characteristics of fashion enterprises and to inquire out the general characteristics affecting the introduction of SCM. The characteristics of apparel manufactures were also compared through the cluster analysis of the SCM activity levels of apparel manufactures. Through questionnaire survey, a total af 214 data - 123 from 64 apparel manufacturers, 46 from 40 fabric suppliers and 45 from 4 retailers - were used for analysis. The analysis on the relation between the SCM activity levels and the general characteristics of fashion enterprises showed that the SCM activities were affected by product assortment pattern and SCM introduction level for fabric suppliers, production method, product assortment pattern, business type and SCM introduction level for apparel manufacturers, and SCM introduction level for retailers. The cluster characteristics related to the SCM activity levels of apparel manufacturers showed that the clusters with higher level were tending to doing business internationally and trying to manufacture in a small lot in variety. The higher level clusters also revealed relatively low in the occupation ratio of fashion goods and high in quick response ratio compared to the lower level clusters.
