ProducerProducerThe scholars focus on the price strategy of the bundling, they set the optimal price not only using the basic of the economic theory
but also the mathematical method
(Adams & Yellen, 1976; Guiltinan, 1987; Eppen et al., 1991; Venkatesh & Mahajan,
1993; Robert & Hermann, 2000)
ConsumerConsumerThe scholars focus on the consumers evaluate
the processes of separate products or the preference of consumers behavior.
(Varadarajan, 1985; Yadav & Monroe, 1993; Yadav, 1994; Yadav, 1995; Harlam et al., 1995)

The scholars investigate the diffusion of multiproduct most only discuss the relative of the multiproduct (Gupta, Jain & Sawhney,1999; Kim, Chang & Shocker,2000; Shocker, Bayus & Kim, 2004)
The multiproduct interaction on process of innovation diffusion (Peterson & Mahajan, 1978)

The Concept of Diffusion
Definition:
“The Information about an innovation (or product) is transmitted through certain channels over time among the members within a social system,” by which the communication channels consist of both the mass media and interpersonal communications (Rogers, 2003)
Communication Channels
The communication channels, which are the process by which people develop and share the information about the product with each other to reach a mutual understanding within the social system, consist of both the “mass media” and “word-of-mouth.”

Frank Bass
Connections result in Imitators According to the concept of Bass diffusion model, the adopters
of an innovation are categorized as:
◦ Innovators: the adopters who are influenced by mass media
◦ Imitators: the adopters who are influenced by interpersonal communications.

Model 1 : Market Equilibrium under multiproduct monopolyObject : find the potential market
Model 2 : diffusion Model of Market EquilibriumObject : find the timing point that the consumers will only willing purchase single product
Model 3 : bimodal profit function model Object : find out the profit what the firm earn in the different timing of bundling

If the cost of management and market in the bundling product B is low, then the optimal bundling time is the former critical time point.
112/04/21 31
We proposed a diffusion process of bundling product. With this process, the firm could find the optimal timing to bundle two products at their life cycle.
Two critical time points are found. If the firm miss the first time point, the better strategy would be waiting for the next time point.
