Figure Lengend Snippet: Conceptual diagram of modelling approach. The overall model consists of three main components: (1) the DES model that projects the number of product launches and the clinical trial costs, (2) the economic and health benefits model which projects the potential economic and health benefits from product launches and (3) the economic analyses that calculate the BCRs and ICERs of the different design options. BCRs benefit–cost ratio; DES, discrete event simulation; ICERs, incremental cost-effectiveness ratio.

Figure Lengend Snippet: FIGURE 7: Modeling the PHY link using MATLAB DES. The waveform entity enters the DES module, stays for a period and then left the module. Only one waveform type storage is created. waveformEntry(), waveformTimer() and waveformExist() are actions.

Figure Lengend Snippet: FIGURE 10: APP Layer Design using MATLAB DES. The messages from mobility model applications are converted into payloads and sent to the MAC layer. When receiving payloads from the MAC layer, the messages are extracted and dispatched to different mobility models.

Figure Lengend Snippet: FIGURE 11: Modeling the APP layer using MATLAB DES. The APP DES module generates payload entities containing messages from the mobility models and sends to the MAC DES module. The received messages may update the traffic information in mobility models. The mobility models are inte- grated and make the vehicles move by the rules.
