Timing Successive Product Introductions with Demand Diffusion and Stochastic Technology Improvement基于需求扩散和随机技术进步的连续产品引入过程 R.

Rather, the firm may prefer to delay an introduction until sufficient incremental new product technology has accumulated in R&D. The objective of this paper is to characterize the firm’s optimal product-introduction policyIntroduction The total number of product generations is not pre-specified; rather, it is determined by the pace of technology improvement along with the firm’s dynamic decisions on when to introduce. Analysis is centered upon two key influences affecting the introduction timing decisions: – (1) demand diffusion dynamics, where future product demand is a function of past sales– (2) technology improvement process, specifically the concept that delaying introduction to a later date may lead to the capture of...
