A computer expert system for guiding Japanese style meal menu has been developed by using EXSYS Professional which is one of expert system developing software tools. The expert system nunderstands the situations of clients, and can guide the menu as human experts do by its software program with expert knowledge about the meal menu. In developing the expert system, the elements the clients consider when selecting menu were arranged as questions of the expert system, and the final outcome of the expert system resulted in selecting the final menu appropriate for the client demand, weather, health, etc. In hotel, the expert system can be shared by whole restaurants, and be directly a computer guider to the clients to tell the best choice of the menu. Besides, it can be used for various kinds of bangquets and events. Expert system has been developed and studied by business managers, manufactures, medical fields, and military field. But the studies for applying the expert system in the fields of foods have been scare. Through this study, therefore, the expert system is going to be applied more widely in many fields fo food events.

Accident analysis is special concern to researchers in traffic safety. Accident analysis in product safety, however, is not. The needs of product safety management alter it in the world by all manufacturers. The purpose of this study is to propose a theoretical principles for product safety management through the accident cost analyses. The accident cost is a important factor to prevent product accident and to treat some claims of customers. It is sure that this principles can help all making decisions of manufactures with expected accident cost per a product accident and with total expected accident cost.

This paper considers an Integrated one-vendor multi-buyer production-inventory model where the vendor manufactures multiple products In lot at Her associated finite production rates In the model. It is allowed for earth product to be shipped In lot to the buyers before the whole product production is not completed yet. Each product lot is dispatched to the associated buyer In a number or shipments. The buyers consume their products at fixed rates. The objective is to the production and shipment schedules in the Integrated system. which minimizes the mean total annual cost per unit time. The mean total annual cost consists or production setup cost inventory holding cost and shipment cost. For the model, an Iterative optimal solution procedure with shipment consolidation policy incorporated is derived. It is then tested through numerical experiments to show how efficient and effective He shipment consolidation policy is.

Supply chain is the link that moves products between suppliers, manufactures, wholesalers, distribution, retailers and ended consumers. Supply chain management(SCM) is a way to supervise the flow of products, materials and information as they move along the supply chain. In the recent years, Most of the companies are in a hurry the introduction of SCM to obtain international competitiveness. The goal of SCM is to optimize the supply chain, which can not only reduce inventories, but may also create a higher profit margin for finished goods by giving customers exactly what they want. There are four major decision areas (location, production, inventory, transportation) in supply chain management, and there are both strategic and operational elements in each of these decision areas. This paper is concerned with the integrated production planning problem including not only the production cost but also the transportation cost in supply chains, and an efficient algorithm using genetic algorithm and quickest path method is presented to solve the problem.

The aims of this research were to suppose the basic data to the producer for more useful manufactures production. 700 pieces of questionnaire were made and 552 pieces of questionnaire were used for this study. The results of this research are as follows ; Many consumers feel uncomfortable to using the unfinished clothing and by the point we could expect the shape retention finish has great possibilities. Just half percent of the people knew about the shape retention finish. So the producer have to do more advertisement for the shape retention finishing and functions. Generally the consumers are satisfied with the shape retention finished clothing.

The aim of this paper presents to develop a computer-aided design system for water gate on AutoCAD R2000system. The developed system has been written in AutoCAD and Visua ILISP with a personal computer, and is composed four modules which are the gate-lifter input module, guide-frame input module, template input module and upgrade module. Based on knowledge-based rules, the system is designed by considering several factors, such as width and height of a water gate, material, object of product and maximum depth of water. Employing the developed system enable the designer and manufactures of water gate to be more efficient in this field, and its potential capability for enhancement included FEM(Finite Element Method) and quotation system.

In the study, we described on the 3D solid model be made on the AutoCAD haved an effect on the deviation of form as RP manufactures the facetres. The STL file improved the deviation of form as the facetres value but the deviation of form have the difference a little as the RP system. In result, we ruled the correlation with the 3D solid model and the RP sample manufacturing, with manufacture RP sample according to facetres value in complex shape. And we developed the program which recombination the STL file that we make use of the AutoLISP.

4D printing is a method that manufactures a programmed transformable 3d printed components that can be transformed in a pre-designed environment. We propose a service-oriented web architecture for supporting 4D printing system. Service model is classified under four kinds of functions: design, sharing, application and production. We designed RESTful web APIs for these functions. Some preliminary designs about the web API architecture and data modeling is discussed.

All the systems can be used properly for the original purpose when they can make the functions required for the users be concrete. Especially in the case that many technical systems are integrated like railroad systems, physically useful systems could be built if requirements analyses applying systems engineering and the process of functional design had to be supported. This paper is intended to review and present the measures and procedures to correctly supply the systems to users by giving systems manufactures and suppliers requirements in order to supply safe systems using safety analysis techniques named FHA(Functional Hazard Analysis) and Hazop Study.

The advancement in semiconductor technology is leading toward smaller critical dimension designs and larger wafer manufactures. Due to such phenomena, semiconductor industry is in need of an accurate control of the process. Photolithography is one of the key processes where the pattern of each layer is formed. In this process, precise superposition of the current layer to the previous layer is critical. Therefore overlay parameters of the semiconductor photolithography process is targeted for this research. The complex relationship among the input parameters and the output metrologies is difficult to understand and harder yet to model. Because of the superiority in modeling multi-nonlinear relationships, neural networks is used for the simulator modeling. For training the neural networks, conjugate gradient method is employed. An experiment is performed to evaluate the performance among the proposed neural network simulator, stepwise regression model, and the currently practiced prediction model from the test site.
