  • At present, company has to produce a product that consumer like with a competitive price, a good quality, and a fitting time to supply. Process control and qualify control are very important to supply with a product uniformly and inexpensively In this paper, the characteristic of product quality is monitored by control chart during the machining process and construction of quality control cycle is considered to divide into two types in this case that different assignable causes lead to shifts having different magnitudes. Then we are intended to find a process shift magnitude which has economical quality cost policy and are considered to quality cost functions to find a process shift magnitude. Those costs are categorized into the well-known categories of prevention, appraisal, and internal failure and external failure. This paper ends with numerical examples that demonstrate the usefulness of the model.

  • This paper considers an Integrated one-vendor multi-buyer production-inventory model where the vendor manufactures multiple products In lot at Her associated finite production rates In the model. It is allowed for earth product to be shipped In lot to the buyers before the whole product production is not completed yet. Each product lot is dispatched to the associated buyer In a number or shipments. The buyers consume their products at fixed rates. The objective is to the production and shipment schedules in the Integrated system. which minimizes the mean total annual cost per unit time. The mean total annual cost consists or production setup cost inventory holding cost and shipment cost. For the model, an Iterative optimal solution procedure with shipment consolidation policy incorporated is derived. It is then tested through numerical experiments to show how efficient and effective He shipment consolidation policy is.

  • A novel mixed-integer linear programming model for the short-term scheduling of a sequential multipurpose batch plant is addressed. First, a time slot domain to each unit is introduced. By assigning each time slot to a product, we obtain the production sequence that minimizes makespan. For multiple-unit assignment problem where a few parallel units with the same function exist, production paths are defined for the distinction of the same stage with a different unit. As a second issue, the model adapted for sequence dependent changeover is presented. For a time slot of a unit, if a product is assigned to the time slot and a different product is assigned to the adjacent time slot, the changeover time considering this situation is included. The performance of the proposed models are illustrated through two examples.

  • Current studies on products of analytic functionals have been based on applying convolution products in D' and the Fourier exchange formula. There are very few results directly computed from the ultradistribution space Z'. The goal of this paper is to introduce a definition for the product of analytic functionals and construct a new multiplier space $F(N_m)$ for $\delta^{(m)}(s)$ in a one or multiple dimension space, where Nm may contain functions without compact support. Several examples of the products are presented using the Cauchy integral formula and the multiplier space, including the fractional derivative of the delta function $\delta^{(\alpha)}(s)$ for $\alpha>0$.

  • This paper reviewed the relationship between innovation(organization innovation, personnel innovation, product innovation, process innovation) and firm performance in small business. Based on the responses from 218 firms, the results of multiple regression analysis showed that personnel innovation, product innovation, and process innovation effect positively on all firm performance(sales, profit, market share, customer satisfaction), and organization innovation effects positively only on market share and customer satisfaction. The results of hierarchical regression analysis showed that technical innovation(product innovation, process innovation) effects more positively on sales, profit and customer satisfaction than administrative innovation(organization innovation, personnel innovation).

  • Consumer's demand level for products and goods selection power is considerably improved. The pressure of loss compensation is also being accelerated by products which bring damage on property. The producer prevents the loss from causing poor products and considering the quality cost allotment in these circumstances. That is to say, producer should be concerned with the strategy of product liability prevention instead of passive defence policy. This paper intends to estabilish the optimum quality cost in considering product liability, and present the correlation of quality cost elements and multiple regression analysis. It can utilized in qualitycost and budget planning.

  • This paper reviewed the relationship between social capital(interaction, trust, shared vision) and innovation(product innovation, process innovation), and the moderating effect of CEO's entrepreneurship in small businesses of Convergence Federation. Based on the responses from 252 responses, the results of multiple regression analysis showed that interaction and shared vision effect positively on product innovation and process innovation, but trust effects positively only on process innovation. The results of moderating analysis showed that entrepreneurship effects positively on the relationship between trust and product innovation, and the relationship between shared vision and process innovation.

  • Tablet product design problem was structured as constrained optimization problem and subsequently solved by multiple regression analysis and Lagrangian method of optimization. Aluminum flufenamate was the drug chosen and microcrystalline cellulose nad starch were the binder and disintegrant, respectivley. The effect of the binder and disintegrant concentration on tablet hardness, friability, volume, in vitro release rate, and urinary excretion rate of drug in human subjects was recorded. Since a reasonably rapid release rate of drug is generally an important objective in the design of solid dosage form, optimization of this parameter was employed in studying the applicability of constrained optimization to a pharmaceutical product design problem. In addition to finding optimal sitivity analysis studies to such problems was also illustratd. It would appear that prediction of the in vivo t$_{50%}$ response from a knowledge of the incitro t$_{50%}$ response can be made fairly accurately for the tablet system used in this study.

  • In this paper, we propose two-stage multichannel architecture for oyster product management system, called cloud stage and agent stage. There are two communication channels at each stage. In cloud stage, the embedded system in the smart scale communicates with the server through two channels, Ethernet or 3G/LTE mobile communication. In agent stage, PCs and smart phones called agents communicate with the server also through Internet and 3G/LTE mobile communication. Compared with previous system in which the amount of the oyster produced in oyster workplaces could be monitored only at the console of only one oyster main server, developed system makes it possible to monitor the amount of produced oyster at several PCs (or smart phones). In addition to the amount of oysters produced at all oyster workplaces the environment of oyster workplaces such as temperature and humidity can be monitored on agents to judge the freshness. Two-stage architecture with multiple channels makes it possible to monitor the amount of oyster product and environment of the oyster workplace at any place in real time.

  • The purpose of study were 1) to find whether brand loyalty is reasonable measurement for market segmentation or not, 2) to know consumers' purchasing behavior by marketsegmentation, 3) to draw preference jean product. Objects were 462 high school students who live in Seoul and random sampling referred from "Korean school guide book". The questionnaires were selected from the previous studies and various bibliographies. For statistic analysis, percentage, average, ANOVA, x2-test, Duncantest, paired t-test, and multiple regression were used by SAS package. The results of this study were as follows. 1) Consumers were classified into affective brand loyalty group, familiar brand loyalty group, habitual brand loyalty group, brand interest but no brand loyalty group, and no brand loyalty group. 2) There were notable differences in clothes purchasing behavior variable through market segments' purchasing (requency, price. 3) The most Prefered jean Product is 80,000 won, domestic well-known brand, baggy style and preferable jean product shows different when it classified brand loyalty.d loyalty.
