For the success of total six sigma innovation, it is necessary to involve the suppliers In the six sigma activities. This paper presents the deployment and support system of six sigma innovation for suppliers, with the application to an aerospace production company. The process of project selection, project implementation, financial effect verification, benefit sharing is presented. This paper will benefit the companies which are going to enhance all the companies in the supply chain via six sigma activities.

This paper has shown that Linear Induction Motor(LIM) and Rack and pinion type are efficient in selecting railway routes and systems after considering time, geo-spatial characteristics and the floating population by benchmarking domestic and overseas mountain trains. The benefit-cost analysis through the use of modeling on user's willingness to pay is conducted as a means that provides access to tourism resources. this paper concludes that the benefit-cost varies in response to changes in the amount of user's willingness to pay by age. It is expected that this paper serves as a reference data in the introduction stage of the mountain train project implemented by central or local governments with tourism resources in mountainous areas as the mountain train has turned out to be economically efficient while various potential benefits that have not been included in the benefit-cost analysis need to be quantified and remain to be studied further.

In health care, the process of resource allocation becomes a controversial process of rationing, as scarce resources are allocated between the numerous health care interventions. Especially for the last few years, decisions to define and expand the benefit package of National Health Insurance have always become the object of fierce criticism. It is partly because we have not reached a collective agreement as to what the most important criteria for spending priorities are. This paper considers the procedures and the principles which could be used to determine rationing in health care, and emphasizes the need to have explicit principles which determine patient access to care and to have an evidence base to inform rationing decisions. Also, the need to set up a public committee is suggested to take rationing decisions on behalf of government and NHS and to present them as evidence-based decisions.

A study on environmental noise hasn't fully researched yet. As society has developed and the quality of life has improved, people started to show a concern about an environmental noise. To ensure a economic feasibility of countermeasures of noise, it is necessary to apply a cost-benefit analysis on choosing optimum measurements. In this study, we addressed the estimation method of the environmental noise value and several domestic and oversea case studies. We also estimate economic value of noise reduction level which is gained from applying noise reduction measurements.

A reliability-based cost-benefit model for the risk management of oil platforms in the formulation of optimal decisions based on life-cycle consideration is proposed. The model is based on structural risk assessments and the integration of social issues and economics into the management decision process. Structural risks result from the platform's exposure to the random environmental loading associated with the offshore site where it is located. Several alternative designs of a typical platform are proposed and assessed from the cost-effectiveness viewpoint. This assessment is performed through the generation of cost/benefit relationships that are used, later on, to select the optimal design.

There are some efforts to improve the performance of electrical heat pump(EHP) and replace it with an alternative cooling equipment such as gas engine-driven heat pump(GHP), a gas cooling equipment, in order to solve the problem of summer electricity supply through reducing the summer electricity peak. This paper analyzes cost-benefit in accordance with replacement of electrical cooling system by gas cooling system using california standard test and sensitivity analysis of some scenarios.

Recently, information systems(IS) outsourcing has become a very important management strategy of implementing IS and many studies on the IS outsourcing approach had been largely performed in the organizations, but it isn't still show how to outsource the IS functions and how to decide quantitative magnitude for judgement. To offer a quantitative decision model that can help practitioners set priority and reap the most benefits from outsourcing, we show outsourcing structure including 3 factors(strategic benefit, economic benefit and technological benefit) and sub-levels which. is different from the Yang and Huang's model. Also, we compute the weight of alternatives using analytic hierarchy process to find a priority of the IS outsourcing. As a result of analysis, we suggest systematic steps and quantitative model to increase the precision of decision making.

A building and the solar are related to the privilege of solar benefit. To make step, it is required to build up an object, chase the position of object and the solar, find the shadow occurrence. On the subject of direct illuminance, an intensive emission of irradiation is proposed to directly project to the benefit area. Simultaneously on the indirect illuminance, the integration of a finite element incident to the benefit area can be multiplied by the hemisphere luminance. A caution should be paid to eliminate the occupation area of the object around on the hemispherical sky, which can help run more accurate prediction.

Recently, ESS became efficient device to stabilize electric power supply system with the development SG related technology. In fact. there are some constraints to supply ESS, because of the high cost and required space, but rapid technology development for ESS will make it more useful soon. So, through this paper, we analyzed the benefit and demand effect when the battery is applied the building based on the measured energy consumption. After that, we got the conclusion that there is a volume limit in ESS application, in a benefit view point. And we realized that there is a demand violation, and the Cost-based BEMS is the best solution to enhance the effect of ESS application.
