【摘要】 根据HPD传播模型,建立开放式数字作品传播系统(open digital works transmitting system—ODWTS),并对其基本要素进行深入分析,给出用户节点进入传播系统的时间间隔分布以及其等价分布——负指数分布.然后把ODWTS等价为一个广义的多分发源负指数分布的排队系统,通过其状态转移过程和排队论理论,得到系统的平均指标,由此建立ODWTS的HPD曲线分布图,使其能够更加准确、合理的表示数字作品的现实传播过程.最后,结合DDRM方案,做出对数字作品传播过程及传播范围的预测和控制分析.更多还原

【Abstract】 According to HPD propagation model,the open digital work transmitting system is established,and analyzed deeply its basic elements,the time interval distribution of user node entering into transmitting system is given and its equivalent distribution-the negative exponential distribution is given too.Then the ODWTS is tantamount to a generalized queuing system which is characteristic of multi-source and the negative exponential distribution,through its state transition process and Queuing theory,achieving the average indicators of the system,thereby establishing the HPD distribution curve of ODWTS,it can depict the reality of transmitting process more accurately and reasonably;Finally,by the program of DDRM,the prediction and control analysis on transmitting process and scope of digital works are made.更多还原
