    The flexible job-shop scheduling problem has received considerable attention in the production scheduling field. Setup operators are inseparable from the system of a small-volume and widely diverse producing. The work load balance among setup operators is important to increase the satisfaction at work. In this paper, a diversity-oriented multi-objective island based genetic algorithm is proposed to solve the FJSP considering the setup operators as a constraint. The total tardiness of each product and the difference of the setup number between setup operators are regarded as objectives and optimized using the Pareto-based method. When the proposed GA is applied to a test instance with moderate size of the problem complexity, it obtained the two exact solutions within a few seconds. Results show that the proposed algorithm, which was applied to the realistic production planning of the model enterprise, improves diversity of sub-solutions and the local search performance by the introduction of the diversity-oriented evaluation of each island, and emigration strategy among islands.

    This paper describes the optimization of flexible job-shop scheduling problem (FJSP) in small and medium-sized companies with make-to-order (MTO) manufacturing many kinds of products. Incorporating weighted tardiness and set-up worker load balance to the objective function of the problem, we develop Genetic Algorithm (GA) using island model and a study of production data in real world make-to-order manufacturing type small business. Comparing the solutions by developed GA with the values obtained by prioritizing due date alone schedule such as EDD (Earliest due date), we confirm the effectiveness of the proposed method. In addition, we conduct numerical experiments on risk, which is general in the enterprise, and countermeasures by using this technique, and confirm that it is possible to quantitatively evaluate the effects. We suggest that the proposed method has potential to contribute to the business judgment in the make-to-order type small business with products and services by incorporating other objective functions

    The present study evaluated the optimized operation management of a cold air power system at a large-scale medical facilityduring the summer, when the air-conditioning cold load reaches the annual maximum. The evaluation was conducted withrespect to energy costs, CO<sub>2</sub> emissions and robustness of the energy-supply system. Since there are a large number ofpossible solutions as to which machines and which refrigeration levels should be operated, a genetic algorithm (GA) wasused to obtain approximate, applicable solutions stochastically, to determine a daily plan of operation for the refrigerationsystem in a timely manner. According to the operation management plan obtained from the GA, over 10% of the energy costsand the CO<sub>2</sub> emissions can be reduced by improved operation. The stability of the cold air power system when a large-sizedphotovoltaic system is installed or when one of the refrigeration units breaks down can also be evaluated by using the GA. Ina medical faculty we taken up, the estimated reduction in CO<sub>2</sub> by adopting the photovoltaic system was calculated to be about16% compared to the current operation management plan. And also the stability of present energy-supply system wasvalidated except for when the vapor-absorption-type refrigerator was down.

    Heat engines emit huge amounts of exhaust which contain considerable quantities of heat and chemical energies. An increasing public awareness of global warming and oil depletion has required the development of innovative methods of recovering energy from such exhaust. A promising approach is to produce electricity from unburned fuel by using a fuel cell system. The exhaust includes cracked-light hydrocarbons, offering the possibility of applying this system to a power generator. Solid oxide fuel cells (SOFCs) can work at elevated temperatures but have poor thermal and mechanical shock resistance. In this study, we address this problem by operating the fuel cell system in a single-chamber mode, wherein no separation between fuel and oxidant gases is required. This operation provides high tolerance toward thermal cycling and breakage of the electrolyte. As a result, a twelve-cell stack exhibits stable and high performance in the exhaust from a motorcycle.

    A proton conducting, 10 mol% In3+-doped SnP2O7 was characterized by TGA, TEM measurement, and electrochemical techniques. We prepared Sn0.9In0.1P2{plus minus}xO7{plus minus}x samples with various P/(Sn+In) molar ratios from 1.7 to 2.6. Sn0.9In0.1P2O7 with a stoichiometric P/(Sn+In) molar ratio of 2.0 showed a proton conductivity of about 0.19 S cm-1 at 250oC under unhumidified conditions. When the P/(Sn+In) molar ratios were over 2.0, amorphous layer composed of phosphorus compounds were observed over the surface of Sn0.9In0.1P2O7 particles. The proton conductivity slightly increased with increasing the P/(Sn+In) molar ratios from 2.0 to 2.6. It is considered that the amorphous layer enhanced the proton conductivity by surface conduction. On the other hand, the thermal stability of this amorphous layer during heating-cooling cycle was not enough high to apply to electrochemical devises. It is important to prepare Sn0.9In0.1P2O7 with the P/(Sn+In) molar ratio of 2.0 to achieve both sufficient proton conductivity and high thermal stability.

    Single-chamber solid oxide fuel cells (SOFCs) with an anode-supported Ce0.9Gd0.1O1.95 electrolyte were operated in a mixture of butane and air at furnace temperatures of 200-300°C. The electromotive force (emf) of the cell and the voltage drop were strongly influenced by the catalytic activity of the anode for the partial oxidation of butane. The promotion of hydrogen formation by the addition of Ru to the anode caused an increase in the emf and a reduction in the voltage drop. As a result, stable power densities of 44 and 176 mW cm–2 were obtained at 200 and 300°C, respectively.

    A method that can block off electronic current through a samaria-doped ceria (SDC, Ce0.8Sm0.2O1.9) electrolyte is proposed. A thin BaCeO3-based layer 12 &micro;m thick was grown by a solid-state reaction of the electrolyte substrate and a BaO film deposited previously over the substrate surface at 1500°C. A homogeneous junction between the layer and the electrolyte was formed, thus allowing no delamination and cracking of the layer. Tolerance of this layer to CO2 was high enough to suppress decomposition into BaCO3 and CeO2. Open-circuit voltages of a hydrogen-air fuel cell with the coated SDC electrolyte were near 1 V or more in the range of 600-950°C. The resulting peak power density was higher than that of a fuel cell with an uncoated SDC electrolyte.

    We proposed a new type of solid oxide fuel cell (SOFC) operating without using an anode material, where the anode was spontaneously formed by reduction of the electrolyte surface under reducing gas conditions. A BaCe0.76Y0.20Pr0.04O3−α electrolyte most successfully met this criterion. This material showed high mixed protonic–electronic conduction, whereas the open circuit voltage (OCV) of the cell was slightly lower than the theoretical value. The resulting SOFC exhibited reasonable fuel cell performances together with a good stability to thermal and redox cyclings and high resistance to carbon deposition up to 800 °C for dry methane, ethane, and propane.

    In this research project, a bifunctional sensor to measure and purify particulate matter (PM) in diesel exhaust gas was developed in response to the growing interest in air pollutants. The carbon in the PM was burned by using the active oxygen generated during the electrolysis of water vapor in the exhaust gas. PM concentration can be estimated by detecting the current flowing through the sensor. It was also found that the carbon is burned by the electric current, which proves its self-purification potential. Furthermore, sensitivity of the proposed sensor was improved by developing a highly active electrocatalyst.

    With the growing interest in recent environmental problems, monitoring and purification technology of nitrogen oxides released into the atmosphere from diesel engines has been attracting attention. In this study, we focus on electrolysis phenomena that leads to detoxification of the nitrogen oxides. Ionic conducting ceramics were applied for the electrochemical reduction of nitrogen oxides. As a result, nitrogen oxides were reduced to harmless nitrogen by active species generated by electrolysis of water. Because the electrochemical reaction occur in the both electrodes, alternate current will become applicable instead of direct current. Simultaneous reduction of nitrogen oxides at both electrodes suggests the simplification and downsizing of the devices for sensing and purification of nitrogen oxides.
