Feature-oriented software product line engineering is to develop various products by developing product line core assets in terms of features and composing those features. However, the developed product may not behave correctly if the feature interaction problem has not be properly taken into account during the feature composition. This paper proposes techniques for identifying and modularizing undesirable feature interactions effectively. The scientific calculator product line is used for evaluating the applicability of the proposed method.

CC ver.3 is widening evaluation range extent about Security product. As a result, The security product evaluation research need more definite standard that serves to evaluate composition style product. The paper propose a development guide for composition style TOE. This research is suitable in evaluation basis of CC ver.3, and presents Korean-made composition style product estimation plan. This paper used European ITSEM component guide and TOE analysis to present estimation guide method of composition style product.

Mass customization meets various needs of customers as well as produces various products and service in low cost like mass production. However, low cost and product diversity have conflicting concepts. Therefore, in order to solve this problem, we need standardization methods. In this paper, we suggest a method for determining the product platform which is a set of common parts in a product family. To achieve the method, we used the Contradiction Analysis of TRIZ (Theory of Inventive Problem Solving), Using this approach, we found a model that obtains various products within limited resources and conditions. Also, we suggest another method that increases the flexibility of our method by Design Structure Matrix.

The higher develops the industrial techniques, the more reliability of mac hi nary, equipments and systems want the consumers. So, it is a key to succeed in the new-product development that the consumers can put reliance on the product to be made in the product design stage. This study intends to help the product designer and the system manager by presenting them better reliability prediction techniques. For this purpose, the author built some fundamental reliability system models. And then predict the system reliability by estimating the elemental component's failure rate ${\lambda}_i$, and proposed an evaluation model. And also, a system is wrong according to the component's characteristics' degradation, we must estimate the degradation failure rate (average and standard deviation). For this, the "Moment method" is used.

This paper describes an image design process for product development based on human sensibility ergonomics.. The human sensibility about product image can be measured through some statistical methods and translated into product design factors by some mathematical inference logics. This results also can be presented by 3D computer graphic tools, In order to integrate the above processess, a image design process on human sensibility database. Human sensibility database is constructed with the relational ddta of some adjective words and design factors, The next step is to extract the design information from the human sensibility dataabase by fuzzy inference algouithm. This information is used for the input data for the graphic presentation. The final product can be modified according to the customer's requirement.

The relationship between the product design and product image can be defined using human sensibility. If there is a way to grasp the product value or product design that people want most, it could be possible to make and sell user-oriented products. In human sensibility ergonomics, the categories of design factor can be broken into shape and color of the design. Although, the color is the major factor of the design, however, texture were is also an important factor for the shape. In this study, wall-papers that have various shapes of texture were used for the experiment. The purpose of this study was to conduct a sensibility estimation experiment for the product image, and to estimate the parameters of various textures for creating new textures that could be more suitable for human sensibility.

Kano model offers an effective way to understand customer requirements strategically Thus, the integration of Kano model and QFD can reflect customer requirements more effectively in designing new product. Most of previous studies on the integration have been focused customer attributes, but engineering characteristics are used at the final stage of new product design. It is proposed that how to classify engineering characteristics into Kano's elements and how to use the classified results in new product development process in this thesis. A case example is included to explain the proposed method.

The communication between members who participate in the product development project has an effect on the project time, cost, and quality. This reason requires the engineering database which is the kernel of product information. This study focuses on data and process modeling for engineering database related to electronic consumer product. First, Through the definition of engineering database, the characteristics of engineering data, mainly product data are analyzed. Second, The object and class for engineering database are defined. This results of the study can be applied with engineering database design and workflow design of PDM. It also can be used as a reference model when the company develops product with suppliers.

Although project management for new product development is a very important issue, only a few approach from project scheduling has been made. The traditional project scheduling research has focused on the project network with certainty, but the new product development project has some uncertainties in network; Some activities may not need to be peformed, and/or some precedent relationships between activities may not need to be kept. In this paper, a simulation model is introduced in order to reflect uncertainties in project network for new product development. This simulation model can be used as a project scheduling technique for product development. By repeating the simulation, the degree of the risk and the feasibility of the project can be assessed.

Today, rapid development and timeliness of introducing a new product be- comes a more influencing factor of determing its competitive power due to a shortened product cycle, while rapid improvement of manufacturing technology makes product design and manufacturing fuse together. This implies that prod- uct usability evaluation and improvement starts right from its design phase, resulting in less development time and cost. To make this possible, proper as- sessment of human reach is one of essential functions for ergonomic product us- ability evaluation, specifically in the platform of computer-aided ergonomic evaluation models or any CAD system with a built-in man model. In this study, an analytic reach prediction algorithm ensuring the posture that human naturally takes, is presented by employing the methods developed for robot kinematics. Among robot kinematic methods for solving the multi-link system, the resolved motion method was found to be effective to solve human reach as a redundant manipulator model. Also, the joint range availability was used as a performance fonction to guarantee human naturalness. The result is expected to be directly applicable to product usability evaluations.
