Scenario analysis of demand in a technology market using leading indicators

Abstract: This paper proposes an approach to analyze demand scenarios in technology-driven markets where product demands are volatile, but follow a few identifiable life-cycle patterns. After analyzing a large amount of semiconductor data, we found that not only can products be clustered by life-cycle patterns, but in each cluster there exists leading indicator products that provide advanced indication of changes in demand trends. Motivated by this finding we propose a scenario analysis structure in the context of stoch… Show more

“…Compared to previous methods such as ordinal scale based approaches [4,5] that rely on unquantifiable technological attributes, the primary feature of the method is that it can capture market trends for making obsolescence forecasting. In addition, the method includes follow on steps to realize more accurate obsolescence forecasting, including a data mining based approach [8] that determines the time range of the zone of obsolescence using data mining of historical data and a leading indicator method [9] to further identify a leading indicator product among particular types of product with a certain life cycle pattern. These methods have some increase in accuracy of forecasting, but at the expense of increased complexity.…”

“…The obsolescence dates of parts can be obtained by forecasting. There have been several types of methods proposed including traditional methods such as ordinal scale based approaches, in which the life cycle stage of the product is determined from a combination of technological attributes [4,5], methods based on forecasting the product sales curve [6][7][8], and leading indicator methods, in which a leading indicator product can be further identified in each life cycle pattern of products that provides advanced indication of changes in demand trends of products [9]. Results have been mixed in the practical application of these obsolescence forecasting methods, where under certain situations, some of these methods can produce good forecasts and others not.…”

“…Other researchers have considered the expansion of flexible capacity, while the use of different kinds of flexibility and the reconfiguration of dedicated capacity have been studied using stochastic dynamic programming approaches [12,13]. Besides decisions with respect to the volumes and types of capacity, the timings of investment in flexibility, as part of a scenario of capacity expansion, have also been considered in some studies [14,15].…”

“…The uncertain demand is parameterized (Meixell and Wu, 2001) by its deviation from the mean and the correlation between the demands of the two product families. Demands for various scenarios are generated by choosing different levels of deviation from the mean and the correlation between demands of the two product families.…”

“…We consider positive correlation of demand among the product families which can be caused by the industrial life cycle of the leading indicator product, e.g. a chip set, affecting the demand for the other products (Meixell and Wu, 2001). We also consider negative correlation case on the demand of product families.…”
