Minimizing the total number of setup changes of a machine increases the throughput and improves the stability of a production process, and as a result enhances the product quality. In this context, we consider a new product-mix problem that minimizes the total number of setup changes while producing the required quantities of a product over a given planning horizon. For this problem, we develop a mixed integer programming model. Also, we develop an efficient heuristic algorithm to find a feasible solution of good quality within reasonable time bounds. Computational results show that the developed heuristic algorithm finds a feasible solution as good as the optimal solution in most test problems. Also, we developed a web based scheduling and monitoring system for a zinc alloy production process using the developed heuristic algorithm. By using this system, we could find a monthly zinc alloy production schedule that significantly reduces the total number of setup changes.

Purpose: The purpose of this study was to determine the quality characteristics of gluten-free frying pre-mix with insoluble dietary fiber powder (IDFP) from Chinese cabbage by-product. Methods: Frying powder mix was prepared with 0.5, 1.0, 1.5 or 2.0% IDFP. Fried powder mix only whit brown rice powder was used as a control. Spreadability, pick-up ratio and color of batter, texture, moisture and oil contents, oil absorption and sensory evaluation of fried sweet potato were determined. Results: L and a-values of batter decreased with increasing amount of IDFP, whereas b-value increased with IDFP addition. Hardness and crispiness of fried sweet potato increased with IDFP addition until 1.5%. Moisture content of fried sweet potato increased with higher IDFP addition whereas oil content and oil absorption decreased with increasing amount of IDFP. Sensory evaluation of fried sweet potato showed the best results in the 0.5% of IDFP addition group. Conclusion: Overall preference of IDFP samples was significantly higher than that of control. Based on the study, the optimal amount of IDFP for gluten-free fried powder mix was determined to be 0.5-1.5%.

The findings of this study are as follows: first, there are differences in sports marketing mix factors, depending on individual characteristics. Differences are found in gender and living standard with regard to individual characteristics and prices. second, there are differences in brand equities, according to individual characters. third, sports marketing mix factors impact brand equities. fourth, the sports marketing mix factors impact perceive quality, brand recognition, location related to brand image and products. fifth, sports marketing mix factors impact brand equities and consumer behaviors. In regards with brand equities and repeat purchases, sports marketing mix factors impact promotion, products, perceived quality and image. In satisfaction, the sports marketing mix factors impact location, price promotion and product recognition. In the intention of transmission by word of mouth, the factors impact price, products, perceive quality and image.

This paper is for applying interactive fuzzy linear programming for the problem of product mix planning, which is one of the aggregate planning problem. We developed a modified algorithm, which has two-phase approach for interactive fuzzy linear programming to get a better solution. Adding two-phase method, we expect to obtain not only the highest membership degree, but also a better utilization of each constrained resource.

Emotional consumption value orientation has played a significant role to have a direct effect on making purchase in our lives. And emotional value has been dealt within the SPA brand contexts recently. Therefore, the current study investigates how SPA brand consumers' emotional value consumption orientation has affected brand loyalty, with a focus on mediation effects of marketing mix attributes assessment. Results of this research are as follows. First, there was a significant difference between Zara and Uniqlo on the assessment of marketing mix attributes. Second, emotional consumption value orientation had significantly impact on brand loyalty for both Zara and Uniqlo. Third, multi-regression analysis was conducted to find out the mediation effect of marketing mix attributes assessment in the relationships between emotional consumption value orientation and brand loyalty. For Zara, hedonic promotional and pricing attributes of products and place show full mediation effect on brand loyalty. For Uniqlo, utilitarian, hedonic and pricing attributes have impact on brand loyalty. The current study strives to find out how emotional consumption value orientation attected the consumer evaluation process and purchase behavior in the contexts of SPA brand product purchase. Product assessments have stronger effect than place, and hedonic attributes have stronger effect on brand loyalty in comparison with utilitarian attributes. Also, hedonic attributes of product and place have stronger effect on brand loyalty in comparison with utilitarian attributes.

Different from earlier studies which investigated Chinese market from the perspective of macro strategy, this study compares importance of marketing-mix between Korean and Chinese consumers from that of basic marketing. As elements of marketing-mix for the comparison, product quality, brand, product price, atmosphere of a shopping store, advertising, and price discount are selected. The survey research was conducted to test hypotheses in major Korea and Chinese cities, Seoul, Pusan, Beijing, and Shanghai, from Jan. to Feb. 2010. A total of 315 respondents born in 1980s were interviewed individually by well-trained Chinese and Korean research assistants. Results show that the importance of the product price is higher among Chinese while the importances of the brand and the advertising are higher among Korean. It is also found that the product quality is evaluated more importantly among Chinese while the atmosphere of the shopping store is among Korean within .1 significance level. The mean difference of the importance of the price discount between both countries' consumers is not found statistically.

The purpose of this study is to investigate customer satisfaction factors that affect customer loyalty and revisit intention, and the seven factors which comprise the marketing mix that affects customer satisfaction. loyalty, and intention to revisit. The purpose of the project is to propose a research model by testing the mediated effects of customer satisfaction and loyalty using mainly factor analysis, regression analysis, and mediation analysis. First the results showed that the marketing mix 7P factors influence customer satisfaction were identified as service delivery process, product, physical basis, and promotion. The factors that influence marketing mix 7P customer loyalty were tested in the order of service delivery, physical basis, product, and distribution. Second, the factors that affect customer loyalty were artists, service, and prices whereas the factors that affect customer satisfaction were tested in the order of service, artist, cosmetics, and price. Third, the factors affecting customer revisit intention were newly derived as treatment satisfaction, professionalism, and treatment products. Fourth, the relationship between marketing mix and customer revisit intention suggested that customer satisfaction and customer loyalty has a partial sale effect. It can be suggested on the basis of these findings that the effect of makeup service with marketing mix on customer revisit intention was analyzed and a new model was derived by analyzing the mediated effect of customer satisfaction and customer loyalty.

In B2B e-Marketplace for free gifts and goods, product-mix recommendation is provided frequently by analysing customer logs and/or performing collaborative and rules-based filtering. This study proposes a new process that encompasses the genetic algorithm and key working processes of B2B e-marketplace based on the previous cooperate client order data. Efficiency and accuracy of the proposed system have been confirmed by cross-confirmation of accumulated data in the e-marketplace. The system can provide better opportunities for manufactures and suppliers to select optimized product-mix without time consuming trials and errors in their B2B e-marketplace networks.
