The purpose of this study examined the relationships between planned obsolescence and replacement purchase intention. This study also analyze the moderating effect of consumer innovativeness use on the relationship of planned obsolescence and replacement purchase intention. From total 205 survey analysis, this study finds the positive relationship planned obsolescence and replacement purchase intention. The result of analysis indicated that the functional obsolescence had positive effects on replacement purchase intention. The result of analysis indicated that the economic obsolescence had positive effects on replacement purchase intention. The result of analysis indicated that the psychological obsolescence had positive effects on replacement purchase intention. The result also shows that consumer innovativeness had a moderating effect on the relationship between planned obsolescence and replacement purchase intention. Finally, this study concluded with a discussion of the implications of the research findings and directions for future research.

This study analyzes the effects of the obsolescence assets on the asymmetry of costs. Cost asymmetry refers to a lower percentage of costs when sales fall than increases in costs when sales increase. the obsolescence asset induces various decisions, including high maintenance costs and management improvements and replacement of facilities. This study is to analyze the cost behavior according to those decisions. The analysis showed that the higher the obsolescence of assets rate, we found cost elasticity, with a greater reduction in costs when sales decrease than the increase in costs when sales increase. Second, the lower the cost will not appear as the obsolescence of assets rate increases in case that the concentration of an item of property, plant and equipment is high, and when sales decrease. The above result means that the obsolescence of assets rate acts as operating risk and thus operates resources flexibly according to changes in sales, but when the concentration of property, plant and equipment is high, the decision-making constraint make it difficult for the flexible operation.

The paper tests the embodiment hypothesis by measuring the technological obsolescence of a specific year (1990)'s technology and investigating the relationship between labor productivity and technological obsolescence. This approach is based on Salter (1969) that emphasizes the economic aspect of technology. We use the rate of economic surplus as the proxy of technological obsolescence for 10 main industries, including food processing, textiles, chemicals, non-steel metals, steels, metal products, machinery, electronics, precision machinery, and transportation equipments. The result shows that the embodiment hypothesis is not accepted for the overall manufacturing sector. However, we found the vintage effect - a positive relationship between technological obsolescence and labor productivity over time - in textiles, chemicals, non-steel metals, metal products, electronics, and transportation equipments. Therefore, the government should support R&D investment as well as capital equipments investment for the industries with large vintage effect.

The share of advanced technology in modern weapon systems are gradually increasing, and life cycle of components are shortened due to the rapid speed of technological development. On the other hand, the weapon systems have a characteristic that takes a long time in the requirement stage of weapon to the operation and maintenance stage. Due to inevitably, obsolescence of the main components for parts occurs in the acquisition phase. The obsolescence parts could cause delays in mass production schedules, and further adversely affects operational availability due to poor supply of repair parts during in the maintenance phase. However, business managers are obliged to maximize the performance while minimizing the cost of the total life cycle of the design, production, and operation stages. It is necessary to establish and implement an appropriate components and parts of life cycle management plan. In this research, we analyzed the effectiveness of parts obsolescence management through cost avoidance and total life cycle cost that can be reduced through proper parts obsolescence management.

The purpose of this study is to design the algorithm, Predictive Service Component - PSC, for forecasting and judging obsolescence of solar system that is implemented based on the micro-inverter. PSC proposed in this study is suitable for monitoring of distributed power generation systems. It provides a diagnosis functionality to detect failures and anomaly events. It also can determine the aging of PV systems. The conclusion of this study shows the research and development of this kind of integrated system using PSC will be needed more and varied in the near future.

Parts obsolescence is a component type, in which raw materials or parts that make up a weapons system, are developed and produced according to demand, but they age due to changes in technology or market conditions. The weapon system equipment currently being used by the military is having difficulty in procurement, maintenance, and operation because of the obsolescence of parts. Parts obsolescence during the life cycle of a weapons system affects not only the combat readiness of the military but also the economic loss of material, parts, and equipment manufacturers and suppliers. On the other hand, advanced technology has reduced the life span of electronic components that make up the weapons system. In addition, because of the nature of the weapons system, the obsolescence of components takes decades from development to disposal, which has a serious adverse effect on equipment readiness and life cycle costs. Therefore, it is necessary to manage systematically the parts obsolescence from development until the disposal of the weapons system equipment. This study examined the system of component control in developed countries to present a proper management plan for local situations and propose development plans for the early settlement of component control.

Engineering valuation is a specialized discipline requiring expert knowledge and judgment, which scientifically estimates the economic value of industrial properties. By industrial properties, we mean engineering structures such as mines, factories, buildings, machines, and other industrial facilities as well as facilities of public enterprises. Particular industrial properties can have longer economic life if their performance is excellent and they are still suitable for current manufacturing needs. If not, its economic life will be shorter. As speed of technological progress becomes rapid, life-cycle and development period of a product is becoming shorter. In an industry characterized by rapid development of technology, industrial properties can become obsolescent faster. Even if they are in good working order, they could be no longer suitable for manufacturing new products based on radically different technology. In our research, we apply engineering approach to estimating functional economic life by factoring in technological obsolescence in such an industry.

The purpose of this study is to investigate and analyze the obsolescence of documents according to their dates, types and locations of publication. The main results are as follows : The half-life of monographs is 12.09 years while those of articles and research papers are 9.68 and 8.93 years, respectively. Moreover, documents are most often cited by researchers within two years since their publication. Lastly, but not the least, the estimated weeding points for monographs, articles, and research papers, assuming that their weeding points have been realized when their accumulated citation rates reach 90%, are 40.15, 32.15, and 29.65 years, respectively.

The purpose of this study is concerned with the development of production for heavy industrial and militaries weapon systems in the field of industries and militaries in Korea. In managing the discontinuance and obsolescence of components and systems. Particularly, defense heavy industries are supporting the designs and production of heavy and weapon systems. Therefore, it is more realistic to manage the discontinues of components and systems, but Heavy and Militaries supports the maintenance of the weapon systems from the maintenance and repairs stage, Discontinued management are imperturbable reality and are moving to be reactive. In order to maintain and operate expensive heavy and weapon systems, it is necessary to manage the Total Life Cycle supportability of the components and systems. Proactive management should be preceded by active management rather than reactive management. In addition, the Information Systems will make you suitable management systems.
