Quality cost system is a key element of an organization's quality program. In this paper we suggest a quality cost evaluation system for aerospace industries considering the aircraft development and manufacturing processes. To reduce the cost of poor quality, we present an extended quality cost concept and detailed quality cost categories. The extended quality cost includes prevention cost, appraisal cost, failure cost, and the cost hidden in the processes. The evaluation of this extended quality cost will be helpful in identifying critical quality issues in aerospace industries.

Quality is a critical competitive factor in today's environment because of the impact of quality on costs and delivery. Many companies regard quality as a key concept of company strategy in order to achieve the competitive edge. Measuring and reporting quality cost is the first step in quality management program. The supposition of quality cost model is that investment in prevention activities will bring rewards from reduced failure costs, and that further investment in prevention activities will show profits from reduced appraisal costs. In this study, the degree of quality cost deviation is conceptualized. This means a deviation between the ideal and present ranking in the amounts of quality cost categories. This study analysed that the effect of its deviation on quality management activity and performance variables. However, there are no difference in these variables. The major reason is that most of companies are endeavoring for quality management but operating quality cost system unsystematically. The review against a prevention and appraisal activity is necessary.

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.

The paper aims to apply a model of continuous quality improvement (CQI) to Taiwan provincial Pin Ton hospital. Tools of quality control were used both total quality management (TQM) and quality control circle (QCC) in order to approach the objective of ${\ulcorner}$higher quality, higher efficiency, lower cost${\lrcorner}$. During two years, this hospital has organized thirteen QC circles that were classified three categories according to that objective: four circles work for higher quality; the other four circles work for higher efficiency; five circles for lower cost. After implementation, several results were found from two viewpoints. From viewpoint of tangibility, one of the most outcomes is to reduce labor cost from 56 persons to 28 persons of temporary employees. From viewpoint of intangibility, the result was evaluated using radar chart to compare the difference after improvement. This paper is going to report the process of CQI for the hospital management because it is a new issue in Taiwan since 1997

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 quality control are very important to supply with a product uniformly and inexpensively. Process control is given much weight in the quality control in manufacturing system. Statistical process controls(SPC) that are used in process generally have major impact on manufacturing, product design activities, and process development potentially. Control charts in statistical process control method can be interpreted the data from quality characteristics in production process and discriminated between chance variation and assignable variation in process. In addition, control chart can be used to monitor the process output and detect when changes in the inputs are required to bring the process back to an in-control state. The models that relate the influential inputs to process outputs help determine the nature and magnitude of the adjustments required. 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.

The purpose of the study was to identify the standards of quality management in contract foodservice companies. The subject companies were selected by convenient sampling and surveyed for their standards. The questionnaire consisted of 7 categories: managements of food procurement, menu, production, personnel, equipment, information system, and solid waste. As a result of the study, 60% of the respondents appeared to use standard recipes, 51.5% of them spent 21-30% of the total cost as a labor cost, and 70% were reluctant to answer the food cost. The half of the respondents had job description and specification, 74.76% had training manuals on foodservice and computer software program, and 80.6% had a training program for solid waste management.

The House of Quality(HOQ) is used in the development stage to identify important customer attributes and corresponding engineering characteristics. The importance of each customer attribute obtained in the HOQ affects to the quality of the final product or service. Traditionally, such importance is derived based on the assumption that customer satisfaction is linearly proportional to the product performance. In this paper, we propose a nonlinear function so as to relate the product performance with the customer satisfaction according to the Kano model. A performance goal is obtained by maximizing the total customer satisfaction under a cost constraint and the importance of each customer attribute is developed from the performance goal. Therefore, the proposed approach incorporates the Kano categories and the improvement cost in determining the importance of customer attributes.

This study was performed to investigate the relationship between diet quality and food cost and identify the effects of food cost on healthy diet among Korean adult. Among the subjects of 2001 National Health and Nutrition Survey 1,641 men and 1,765 women aged from 30 to 49 years were selected and their information of dietary intakes, socio-demo-graphic information, and anthropometric data were analyzed. For the analysis, subjects were classified to quartile based on their daily food cost. Food guidelines provided by Korean Nutrition Society was regarded as a model of healthy diet. Subjects in the lowest quartile of food cost consumed inadequate amount of food from all food categories of the guidelines. Many subjects in the highest quartile not only satisfied the recommended amount of the Food Guide but also seemed to overeat high energy density foods. Even in the highest quartile, about 90% of subjects did not satisfied recommended amount of dairy products. According to the calculated cost of healthy diet, the average cost did not seem to be more expensive than the current mean food cost of the subjects, and most cost-sensitive food intake was observed in the meat fish beans eggs category. The implications of study results were: 1) all the high cost diets did not indicate the high quality of diet, 2) most practical matter of healthy diet in low income group seemed whether they could afford the expense of meat and fish, 3) nutrition education was required to most subjects for healthy diet.

To date, SCM research has mainly focused on the effects of controlled variables on SCM success and emphasized adoption strategies and critical success factors. Consequently, the effects of more uncontrolled variables such as partnership between SCM partners have been largely ignored. The purpose of this study, therefore, is to examine the effects of both controlled variables and uncontrolled variables on SCM performance through affecting RTE characteristics. The six factors examined in this study include Quality of information, partnership quality, Forecasting, Agility, Visibility, and SCM performance. In this study, SCM Performance was divided into three categories: Quality Performance, Cost Performance, Delivery Performance. All factors were examined from the perspective of part suppliers. The results of this study can be summarized as follows. First, SCM information quality positively affected SCM partnership quality, Forecasting, Agility, Visibility. Second, SCM partnership quality positively affected Forecasting, Agility. But, SCM partnership quality showed no significant effect on Visibility. Third, Forecasting had a significant impact on SCM performance. According to the detailed result of measuring SCM performance with Quality Performance, Cost Performance, Delivery Performance, although Forecasting affects Cost Performance, Delivery Performance directly, it does not affect Quality Performance directly. Fourth, Agility also had a significant impact on SCM performance. According to the detailed result of measuring SCM performance, Agility has significant impact on Quality Performance, Cost Performance, Delivery Performance. Fifth, Visibility, as expected, had a significant impact on SCM performance. According to the detailed result of measuring SCM performance, Visibility has significant impact on Quality Performance, Cost Performance, Delivery Performance.
