Opis:: Characteristic that is hard to obtain in the calculation in product development. The sensory characteristic is often had such as sound quality, visual sensation and tactile sensation. The evaluation method for visualizing the determination of the customer is being established by applying Taguchi-methods and so on. The fact is still got many corresponds with the method of Try & Error as numbers of cases are small in order to optimize the properties. Therefore, the study was conducted of the method for optimization of sound quality by using the innovative tool using Taguchi-methods that newly developed. The research results are summarized as follows. (1) Sensory characteristic tuning method by using Taguchi-methods was calculated the values to be optimized in a few studies, and the result was equal to or greater than the result of specialists is carried out. (2) Commonly, the sensory characteristic of optimization is conducted with the method of Try & Error; moreover, it could be confirmed that leading to improvement of productivity by using this method even though it takes time to perform so as to optimize under changing in physical condition and environment.

Opis:: Recently Taguchi methods are used to decide optimum processing conditions with narrow dispersion for robust design. On the other hand, innovative development with short-term, low cost, labor and energy saving is also required in the world. In this study, the software for development of a product with optimum condition using Taguchi methods is developed and evaluated. There are two trials in the software using Taguchi methods. First trial investigates rough functions regarding all levers of all control factors, then important control factors and meaningless control factors were sorted with the several comments for the second trial. At that time, maximum, intermediate and minimum values for each lever of each of the control factors should be used for pursuit of all possibilities. In the first trial, the relationship between each level value of each of the control factor and the desired property is also decided by the function, then the optimum combination using each level of each of the control factors were calculated for the second trial by using the function. The second trial is confirmed for the best combination using the estimated optimum level values. For example of an application, the optimum design for the paper craft “airplane” was investigated for evaluating this software in the experiment. It is concluded from the result that: (1) The proposed software was useful for developing with short-term and lower cost, (2) This tool could quickly and exactly decide the optimum design condition and (3) The paper craft “airplane“ with most long flying length is manufactured by using the developed software.

Opis:: As swift development with low cost was required for the manufacturing in industry, CAE simulation was used to predict the result of the design process, and Taguchi methods was used to decide optimum conditions for minimizing the dispersion.In this study, the perfectly design system without trial production using CAE and Taguchi methods was developed and evaluated. Software for original Taguchi methods and software for productivity management were firstly created, these softwares were combined with established CAE, and software package was developed for estimating the optimum combination of design parameters. Then the quality and the functionality were advanced to gain the optimum condition for the maximum profit considering the function of the grading of products, the delinquent charge and the loss function in the quality engineering based on the developed software. The research results are summarized as follows. (1) Perfectly design system without trial production using Taguchi methods was developed for calculations of the grading products, adding the delinquent charge and the loss function. (2) The evaluation with Kami-copter contributes to the profit evaluation of the grading; the delinquent charge and the loss function with high dimensional accuracy and is evaluated effective on industry.

Opis:: This paper contains a mountain pass theorem for continuous mappings, defined on a complete metric space and taking values in a real Banach space, ordered by a closed convex cone. We use the concept of critical point introduced by Degiovanni, Lucchetti and Ribarska, and we furnish a variant of their result, allowing for a localization both of the critical point and of the critical value.

Opis:: In line with the ambition of ship-owners to preserve capital and reduce operational costs, the selection of an optimum, safe and secure route for an envisaged voyage has always been a challenge for ship-owners, masters, and engineers. Due to the many complexities and parameters that affect the selection of an optimal route, the topic has become very interesting to many researchers. Each of the parameters affecting the process of route selection has its own values and weights, and these values change depending on specific situations and objectives. This sensitivity to context increases the difficulty selecting the optimum route. In this research, the optimization of a tanker-sized VLCC voyage for predefined and different routes is addressed in order to identify the optimum route. To reduce the number of variable parameters, major values have been assigned to the ship profile and sea conditions. The time domain analysis and the solution of equations of motion are then performed. The proposed route is designed by using a Bezier curve, and this route is then optimized with the objective of decreasing fuel consumption using the Fletcher-Powell method. The resulting optimized route shows a 3.7% savings in fuel consumption.
