چکیده
The expressions for y2(t) and Y2(t) shown in Equations (11) and (12) are valid only if G2 is the latest generation available. Now suppose a generation 3 (G3) is introduced at τ3 (τ3 ≥ τ2). Similar to the shifting from G1 to G2 after τ2, some of the existing and potential adopters of G2 will consider adopting G3 after τ3. In order to derive the number of leapfrogging and switching adoptions between time τ3 and t, we first

A Generalized Norton-Bass Model for Multigeneration Diffusion
The Norton-Bass (NB) model is often credited as the pioneering multigeneration diffusion model in marketing. However, as acknowledged by the authors, when counting the number of adopters who substitute an old product generation with a new generation, the NB model does not differentiate those who have already adopted the old generation from those who have not. In this study, we develop a General...
متن کاملBibliography for EC ’ 12 Tutorial : The Diffusion of Networking
Marketing. This is the original 1969 paper that proposed the Bass Model [2] for understanding the diffusion of new products. It has been claimed that this model is the most popular model used in marketing. It’s perhaps easier to read this retrospective written by Bass [3], or this earlier more detailed survey on the Bass Model [18]. I also mentioned the Bass-Norton model for successive generati...
متن کاملImplementing support vector regression with differential evolution to forecast motherboard shipments
In this study, we investigate the forecasting accuracy of motherboard shipments from Taiwan manufacturers. A generalized Bass diffusion model with external variables can provide better forecasting performance. We present a hybrid particle swarm optimization (HPSO) algorithm to improve the parameter estimates of the generalized Bass diffusion model. A support vector regression (SVR) model was re...
متن کاملA thermodynamic model for exergetic performance and optimization of a solar and biomass-fuelled multigeneration system
Integrated energy systems utilizing renewable sources are sustainable and environmentally substitutes for conventional fossil-fired energy systems. A new multigeneration plant with two inputs, such as biomass and solar energy, and four useful outputs, such as cooling, heating, power, and distilled water, is presented and investigated in this paper. The proposed system includes evacuated tub...
