A successful product development process can not be achieved without a proper focus and prioritization. For this research, the priority is defined as the relative urgency of a system compared to other system in order to develop and launch a successful product. The process of integrated approach for prioritization using ID and Goal Programming is developed. The development of a mid-size car by an internationally reputed automotive company is described as a case study.

Building management cost increases enormously as modern buildings become complicated. Lost of building eveners or managers feel the need to cut down the cost not sacrifying Comfort building environment and building safety, The ways to achieve such goal are maintaing with a few person, proper HVAC scheduling to save energy BAS's i.e the building automation system or building maintenance system, are designed to meet the goal. In korea, imported BAS's have been installed past several years. Difficulties arised in several aspects. One is extra high cost in installing BAS's because of marginal coat. Another is long settling time because it is originated from abroad. GSC/85/30 is the first trial as a korean BAS to minimize such difficulties. Even though it is a primitive system, it is a mileston of korean BAS the technics gained from developing GSCI/85/30 can be utilized to develop higher version and is now. As modern buildings become more complicated and hugy, managers owner of buildings seek for the system to manage building properly. BAS(Building Automation System or Building management system) is designed to meet the need.

It is discussed how to assign delivery tasks to automated guided vehicles (AGVs) for multiple container cranes in automated container terminals. The primary goal of dispatching AGVs is to complete all the lading and discharging operations as early as possible, and the secondary goal is to minimize the total travel distance of AGVs. It is assumed that AGVs are not dedicated to a specific container crane but shared among multiple cranes. A mathematical formulation is developed and a heuristic algorithm is suggested to obtain a near optimal solution with a reasonable amount of computational time. The single-cycle and the dual-cycle operations in both the seaside and the landside operations are analyzed. The effects of pooling AGVs for multiple container cranes on the performance of an entire AGV system are also analyze through a numerical experiment.

This cross-level study of 77 samples from Korean 1st-tier suppliers participating in knowledge-sharing networks examined the impact of partnering(joint establishment of goal and joint problem solving system) on supplier relationship outcomes(competativeness improvement and innovative idea suggestion). The findings showed that joint establishment of goal and joint problem solving system were positively related to both supplier's competativeness improvement and its innovative idea suggestion. Whereas, joint problem solving system did account for a significant variance only in innovative idea suggestion. The findings, further, demonstrated that mutual trust moderated the relationship between joint problem solving system and supplier relationship outcomes. Implications for theory and practice are suggested.

In this study, the fuzzy programming is extended to handle various types of membership functions by transformation of the complicated fuzzy programming problems into the equivalent crisp linear programming problems with single objective. It is well-known that the fuzzy programming problem with linear membership functions (i.e., ramp type) can be easily transformed into a linear programming problem by introducing one dummy variable to minimize the worst unwanted deviation. However, until recently not many researches have been done to handle various general types of complicated linear membership functions which might be more realistic than ramp-or triangular-type functions. In order to handle these complicated membership functions, the goal dividing concept, which is based on the fuzzy set operation (i. e., intersection and union operations), has been prepared. The linear model obtained using the goal dividing concept is more efficient and single than the previous models [4, 8]. In addition, this result can be easily applied to any nonlinear membership functions by piecewise approximation since the membership function is continuous and monotone increasing or decreasing.

The values measured at different time and enumerated sequentially by homogenous interval is called time series. Its goal is to predict values in future by analysing the measured values in past. The stastical approach to time series prediction tend to be by a neural approach with difficulties in expressing the reationship among past data. In neural approach, the preblem is the acquisting of the enough training data in advance. The goal of this paper is that such problem is solved by generating another term as virtual term between terms in time series.

The purpose of this study is to empirically examine the role of supplier relationships as a means of enhancement of quality. The model for this study consists of four groups of concepts - 1) goal of quality, as 2) measures of supplier relationships, supplier assistance and buyer supplier communication, 3) the level of automation and technology, as 4) measures of performance, reliability quality and performance quality. By statistical analysis, the results are as follows. First, the goal of quality positively influences the level of automation, technology, supplier assistance and supplier communication. Second, the level of technology has a positive effect on supplier assistance and supplier communication on the level of automation. Third, the level of automation and technology positively influence the reliability quality. Fourth, supplier assistance and buyer-supplier communication has a positive effect on the reliability and performance quality. These results reveal three paths of supplier relationships in systems for the enhancement of quality.

The purpose of this study was to identify the effects of nursing simulation-based practice education on learning outcome and teaching experience in nursing students. Pretest-posttest design with nonequivalent control group was utilized to analyze the effects of nursing simulation-based practice education. The subjects were 96 students of a nursing college. All subjects participated in 6 week. The data were analyzed by the SPSS win 17.0 program. The results were as follows; There were statistically significant differences in learning outcome and teaching experience effects of nursing simulation-based practice education in nursing students. In conclusion, we required nursing simulation-based practice education and small group discussion analysis of factors are associated with goal-setting skills and self-presentation skills, goal setting skills. We required nursing simulation-based practice education training to strengthen the ability of self-directed learning program utilizing the repeated study.

The goal of this study was to contemplate the impact of visual formative elements on the satisfaction level of visitors in websites of toy-style products. To attain the goal, the visual element of motion graphics in websites of toy-style products, i. e., color, layout, illustration, and, typography, were independent variables and the satisfaction level of visitors as a dependent variable. The variables were analyzed objectively. First, it appeared that visual formative elements of motion graphics appeared in websites of toy-style products exerted statistically significant impacts on the satisfaction level of visitors. Second, the element exerting the most significant impact on the satisfaction level of visitors among the visual formative elements in websites of toy-style products were appeared as 'illustration' and 'color'. Thus, it was concluded that it is necessary to give priority in 'illustration' and 'color' to enhance the satisfaction level of visitors.

In this paper, we propose a multi-Criteria decision making approach to address the problem of finding the best possible solution in credit unions. Sensitivity analysis on the priority structure of the goals has been performed to obtain all possible solutions. The study uses the Euclidean distance method to measure distances of all possible solutions from the identified ideal solution. The possible optimum solution is determined from the minimum distance between the ideal solution and other possible solutions of the Problem.
