Expanding product variety and high customer service provision place an enormous burden on demand forecasting and the matching of supply with demand in a supply chain. Postponement of product differentiation has been found to be powerful means to improve supply chain performance in the presence of increasing product variety. Delaying the point of product differentiation implies that the process would not commit the work-in-process into a particular finished product until a later point. This paper reviews the recent analytical models that quantify the value of delayed product differentiation. We conclude the literature review by summarizing and synthesizing the economic evaluation of the postponement and outline directions for future research.

This paper examines how online product information changes the customers' purchase intentions from subjectivity-objectivity dichotomy perspective. Quality and Preference are proposed as product evaluation criteria and their marginal changes with product information differentiation are hypothesized. An experimental survey was conducted to 57 subjects and the hypotheses were partially supported through PLS path comparison method. The study contributes to IS research by proposing a simple and effective product evaluation framework and by abstracting the impact of product information from other factors. Finally, we suggest the utilization of product information with the optimization of the cost-benefit structure between information and purchase intention.

In this study, the product complexity is evaluated quantitatively considering the disassembly process of the product. To evaluate complexity of the product, we analyze the characteristics of the product and the disassembly process. And we determine factors, which influence on the complexity of the product in the main-disassembly and sub-disassembly. Considering each characteristics of part and subassembly. Evaluations criteria of complexity are determined. Using evaluation criteria of the complexity can be determined the complexity grade of the product, and then we show the total complexity of the product considering the disassembly process.

With the development of new technologies, virtual reality (VR) is emerging as a new consumer marketing platform. Yet, only a few studies have investigated VR in the consumption context. The current research explores how experiencing a product through VR influences consumer attitude and purchase intention for the product. Although assessing products in real life is believed to be more diagnostic than that through VR, the present research revealed that experiencing a product through VR could lead to a more positive attitude toward and higher purchase intention for the product. We also demonstrated that "enjoyment" has a mediating effect while evaluating the product through VR. To compare product experience through VR to that in real life, we employed the HTC Vive VR system to implement a VR environment. In the VR condition, participants evaluated plastic building blocks using a VR headset and a motion controller; and in the real life (reality) condition, they evaluted plastic building blocks printed using a 3D printer to make them look exactly the same as the blocks used in the VR condition. Finally, implications and suggestions are discussed.

기업이 소비자들의 안전에 위험을 미치는 제품을 판매함으로써 발생하는 '제품위험 위기(product-harm crisis)'는 신문이나 방송 등에서 즉각적으로 보도되기 때문에, 소비자들은 이를 매우 심각한 사건으로 받아들이게 된다. 이로 인하여 소비자들은 해당 기업 및 제품에 대하여 부정적인 태도를 형성하고, 나아가 낮은 구매의도 경향을 보인다. 이에 본 연구는 부정적 언론보도에 대한 기업의 대응방식과 대응시점이 매출액(<연구 1>), 나아가 소비자 반응(<연구 2>)에 미치는 효과를 실증적으로 고찰하였다. 분석결과에 의하면, 부정적 언론정보에 노출된 제품의 경우, 이러한 부정적 영향이 다른 제품군에도 전이되는 것으로 나타났다(<연구 1>). 또한, 부정적 언론정보에 노출된 제품의 경우, 반박보도(변명보도; <연구 2>)보다는 개선보도를 내는 것이 제품평가, 기업평가, 나아가 매출액 회복에 더 긍정적인 영향을 미치는 것으로 나타났다. 끝으로 대응방식과 대응시점의 상호작용결과에 의하면, 개선보도는 대응시점이 빠른 경우보다 느린 경우에 제품 및 기업평가가 더 높게 나타났으며, 반박보도(변명보도; <연구 2>)의 경우는 느린 경우보다 빠른 경우 더 높게 나타났다. 다시 말해, 부정적 언론정보에 대한 대응시점이 빠른 경우에는 반박보도(변명보도; <연구 2>)와 개선보도 간의 제품평가, 기업평가 차이는 없는 것으로 나타났다. 그러나 부정적 언론정보에 대한 대응시점이 느린 경우에는 반박보도(변명보도; <연구 2>) 보다는 개선보도가 제품평가, 기업평가에 있어 더 긍정적인 평가를 받는 것으로 나타났다.

In the process to design a product, the values of the product will be designed must be considered in respect to the multi-dimensional properties consisted of subjective and objective attributes. As same reason, methods to evaluate the design alternatives in the process must evaluate the overall attributes and relationships among its, also. In this paper, the defectivenesses of evaluation methods in the process of product design are summarized. One of the severe defectivenesses of the methods is the insufficient rationality of calculation procedure. Then, we introduce the developed quantitative evaluation method to accomodate this defectiveness and to be considered a evaluator's feeling or ambiguity when evaluating design alternatives by means of fuzzy theory, and suggest it's application steps on the process of product design to be used easily.

보안제품에 대한 평가기준은 CC 버전 3의 등장과 더불어 단일 제품평가에서 합성형 제품의 평가로 그 평가 범위가 넓어지고 있다. 이에 합성형 제품을 평가하기 위한 기준에 연구와 그 도입방안에 대한 연구가 필요시 된다. 본 논문에서는 이러한 합성형 TOE을 위한 개발 가이드에 대해 연구함으로써 CC 버전 3의 평가 기준에 적합한 한국형 합성형 제품 평가 방안을 제시하고자 한다. 구체적인 방안으로 유럽의 ITSEM 컴포넌트 지침과 TOE를 분석함으로써 합성형 제품의 평가 가이드 방안을 제시한다.

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.

When a product is designed, it is important to consider its image on consumers. In this study, we developed a technique to measure product image. Because human image of a product is very subjective and fuzzy, it is difficult to measure easily. To deal with this difficulty effectively, we used fuzzy- weighted checklist. The fuzzy-weighted checklist presents a fuzzy version of the weighted checklist technique for evaluating or comparing complex systems or subjects. In this technique, we used a pairwise comparison method to obtain the relative importance weights of image factors. Also, we used linguistic ratings to obtain the scores of image factors for a product. Then, we synthesized the scores of image factors to obtain a fuzzy composite score and its linguistic approximation. The entire procedure of this technique was written in quick Basic. As an example, this techinque is applied to car evaluation. The results show that this technique can be effectively used to the quqntitative evaluation of huamn image.

기업의 정보보호활동 예산 중 정보보호제품 구매가 가장 큰 비중을 차지하고 있다. 그러나 정보보호제품을 객관적으로 비교하기 위해 적용되어야 하는 평가요소와 평가모델이 없어 제품 선택에 어려움을 겪고 있다. 따라서 본 연구에서는 정보보호제품 고유의 품질 특성을 연구하고 그에 따른 평가 요소들을 선정한다. 선정된 평가 요소들을 분석하여 중요도에 따른 가중치를 부여한 품질 결정 모델을 제시한다. 대상은 네트워크 정보보호제품으로 제한하여 분석하였고 모든 정보보호제품으로 확대하여 적용할 수 있다.
