Each method for economic evaluation has its own characteristics. Therefore adoption of each of them in evaluation production investment project results in many problems. Hence combination & modification of them are required to perform more accurate evaluation about investment project. This paper discuss evaluation method of investment projects expansion and replacement investment on each line or individual in the production. Generally investment evaluation method has add to a few method by Subsidiary means with use a especial method. And then in this paper, a Taguchi Techniques is presented, which may be effective to the facilities appraisal or improvement. We propose a decision model to incorporates the values assigned by a group of experts on different factors in production. Using this model, SN ratio of taguchi method for each of subjective factors as well as values of weights are used in this comprehensive method for reducing production rate in production management.

Moscow is one of well-developed city about intermodal transport system by subway line. But some airports which located in suburb area have really bad transport system connecting downtown Moscow, and many people have experienced a lot of inconveniences. Russian Railways (RZD) established airport rail company in year 2005 and they have operated Aero-Express train from downtown of Moscow to major airports. Intermodal transport system was considered to the construction of Russian airport rail system, and various types of tickets and airport rail terminals are operated by RZD, and subsidiary businesses with airline companies are promoted. This study will analyze the success factors of Moscow airport rail system and introduce the success effects, and considering points for the operation of Incheon airport rail terminal in the future.

The number of domestic ice-rink is little by little increasing recently. Therefore, the demand for air-conditioning system to adjust adequately the indoor condition of ice-rink is constantly increasing. But, if air-conditioning system for ice-rink isn't designed properly, the problems such as fogging, ice surface condensation, structural deterioration, odors, generation of dew condensation on the surface of a wall occur. The solutions for these problems are to lower the relative humidify of indoor. The objectives of this paper is to apply of desiccant dehumidifier on ice-rink, solve these problems.

One of the primary factors like plate structure In ship is redundancy structure that is comparable with ocean structure and frame structure. The more component material becomes buckling collapsed locally the less structure stiffness becomes accordingly. As a result, by increasing the load distribution of any other subsidiary structure continually component member collapses, therefore the structure could be in danger of collapse. So, in order to interpret this phenomenon precisely, the study on boundary condition of the ship's Plate and post-buckling analysis must be considered. In this study, the rectangular plate is compressed by the in-plane load. Buckling ＆ Ultimate strength characteristics we applied to be the elasto-plasticity large deformation by F.E.M. On this basis, elasto-plasticity of the plain plate are investigated. This study proved elasto-plasticity behaviour of tile ship's plate In accordance with boundary condition based on the series analysis In case of the compressive load operation.

This research intends to check what value and convenience the on-line brand community members pursue and how such value and convenience affects brand affection. Researching on-line brand community members of ipod, it was found that their value and convenience is composed of 3 types, namely, functional value, emotional value and self-expression value and the concept of brand affection is composed of 3 subsidiary factors, namely, 'love', 'interest' and 'immersion.' Checking how the functional, emotional and self-expression convenience of on-line brand community members affected brand affection, the following result was found. First, functional value and convenience has significant influence on the love affection only at the level of brand affection and has no influence on the relational and immersion affection. Second, self-expression value and convenience has significant influence only on the love affection of brand like functional value and convenience. Third, it was found that emotional value has significant influence on the 3 dimensions of brand affection, namely, love affection, interest affection and immersion affection.

In this study, we have figured out exercise time and the amount of burned calories, using a three-axis acceleration sensor which we name as a health sensor. What is more, the health sensor calculates the degree of physical exercise taken during exercise. As is generally known, continuing, regular exercise is far more effective than short time exercise for sustainable health management. The health sensor is, therefore, recommended as an instrument to efficiently carry out the health management. Additionally, the health sensor was applied as an exercise subsidiary system to walking and jumping rope tests. In light of their results, the sensor system was found useful for analyzing the pattern of exercise.

Partial nitirification and denitrification process has been reported to be technically feasible and economically favorable, especially for wastewater treatment with high ammonium concentration or low Carbon/Nitrogen ratio. This research was performed to survey nitrite accumulation by nitritation in treating ADEPT effluent of piggery wastewater, which contains highly concentrated ammonia. To estimate the possibility of nitrite accumulation, DO concentration and SRT were investigated as key operational parameters. This result proved that nitritation to nitrite was steadily obtained under short sludge retention time. Oxygen limitation was proved to be just a subsidiary parameter. Energy efficiency of nitritation-denitritation process was higher than complete nitrification-denitrification because external carbon requirement for denitritation could be saved. Though the influent contained significant nonbiodegradable organic substrate, total nitrogen removal efficiency was more than 51% in nitritation-denitritation system.

In this paper, we propose a new type of tubular linear induction motor(TLIM) with two-dimensional motion. The proposed motor consists of four short primary LIMs arranged on a same circumference and a common secondary. By adopting independently energized ring-windings to the primary, we can expect the reduction of coil-end region and the freedom of alternating current supply. The secondary conductor is capable of producing anyone of rotary, linear, and helical motions by controlling the phase of supply currents in each primary winding. From the 3-D finite element analysis and the experiment, we derive the feeding conditions to increase the subsidiary rotary-force and an optimal arrangement of primary currents to reduce the number of slot.

As technique that can contribute in quality improvement in design process to overcome shortcoming of traditional quality control, call design or development department quality control activity that is achieved to reduce gun damage shuddering at circle minimizing change or side effect of product performance as off-line quality control. This paper discuss optimal process design of investment projects expansion and replacement investment on each line or individual in the production. Generally optimal plant design has add to a few method by Subsidiary means with use a especial method. And then in this paper, a Robust design is presented, which may be effective to the processes appraisal or improvement. We propose that should make a optimal plant design model for reducing field failure rate to assign by real data on different factors in plant system. Using this model, robust design of taguchi method used in this comprehensive method for reducing field failure rate in plant system.

Today, several manufacture enterprises are endeavoring constantly to receive order winners of subsidiary company product. There are tendencies to occupy competitive advantage in high position in price competition and in quality etc. But, it is not easy to keep it even if price has been cheap recently. Also, it is hard to be competitive advantage element more, because production smoothing was made much even if there is in quality. To keep or improve present competitive power, the due date rate is becoming importance. Several techniques with MRP, MRP II appeared in the 1970s by method to improve the these due date rate. These techniques have some defects to due date. Therefore, in this paper, MRP wishes to receive the due date rate that is improved more by supplementing having these defect by DBR of TOC.
