Manufacturing today is becoming increasingly competitive. If a company is to exist and successfully compete, it must pay very careful attention to production management, total quality assurance and total proactive maintenance issues. Overall machine performance, repair efficiency, system level utilization, productivity and quality of output need to be optimized as possible. To accomplish that objective, the behavior of manufacturing equipment and systems need to be monitored and measured continuously if it is possible. Then early warning of possible failure should be generated and proacted on that type of the situation to improve overall operation performance of manufacturing environment. In this paper, Proactive maintenance framework using performance-based reliability structure as enabler technology is proposed. Its paradigm enables one to maximize system through-put and product quality as well as resources in the performance domain. In the case of inadequate knowledge of the failure mechanics, this empirical modeling concept along with performance degradation knowledge can serve as an important product and process improvement tool. The real-time framework extension to proposed framework uses on-line performance information and is capable of projecting the remaining useful period.

The study aims to measure the quality of consulting services for village-building projects in rural areas. To this end, the government wanted to analyze the impact of the quality of service on residents' satisfaction and business performance in villages that are receiving consulting services. As a result of the empirical analysis of the case areas, the five-dimensional tangibles, reliability, assurance and empathy of the quality of consulting services in rural villages had a defining influence on the residents' satisfaction. And the residents' satisfaction of consulting services had a defining influence on the business performance of the village with tangibles, reliability, and assurances. The main implications presented on the basis of these results were analyzed that it was necessary to universalize the assessment of service quality, to strengthen the burden of the village on the cost of consulting services, and to induce participation through a sufficient understanding of the villagers' business.

It is very important for the manufacturers to predict the life of hydraulic system components according to the results of life tests. Since it takes too much time to test the hydraulic system components until failure, the no-failure test method is applied for the life test of them. If the shape parameter of Weibull distribution, the number of samples, the confidence level, and the assurance life are given, the no-failure test times of hydraulic system components can be calculated by given equation. Here, the procedures to obtain the no-failure test times of the hydraulic system components such as hydraulic motors and pumps, hydraulic cylinders, hydraulic valves, hydraulic accumulators, hydraulic hoses, and hydraulic filters are described briefly.

The impact of greenhouse gas (GHG) emissions is the global issue over the world. Korean government has presented various policies to induce GHG reduction for the industries with high energy consumption such as power generation and chemistry. Construction sector has produced a large amount of GHG emissions resulted in the energy consumption of heavy equipments and the use of materials. This study aims to suggest the QA (Quality Assurance) and QC (Quality Control) method to identify and quantify the GHG emissions released from heavy equipments in the railroad construction sector. Generally, the accuracy and reliability of GHG inventory is dependent on the data collection. Therefore, it is necessary to mange the detailed statements for the fuel consumption of heavy equipments and the quantity of work in the field. Also, the breakdown of GHG emission sources should be recorded from the design step of railroad infrastructures. Based on these data, the GHG reduction technologies and polices can be applied in railroad construction sector.

This study proposes a risk evaluation method based on RAM and AHP data in order to prevent subjectivity of risk assessment. The risk assessment consist of Risk Likelihood(RL) and Risk Consequence(RC) in five levels. However, risk analysis of warships is hard to make a judgment because of small quantity production(Ship), long building period, equipment changes, complexity, various kinds of equipments, etc. The proposed RAM data and AHP analysis method are used to quantify each level quantitatively. RAM(MTBF) date is used to classify the RL, and AHP analysis is used to classify the RC. These scientific and data-based method will increase objectivity as well as efficiency of risk evaluation.
