55107 仿真实验验证了所建立的模型、算法的合理性和优越性,对未来空天高速飞行器探测预警系统的构建具有一定的技术支撑作用。 The model is verified by simulation experiments, the rationality of the algorithm and the superiority, empty days in the future high speed vehicle detection warning system construction has a certain technical support.
55108 讨论了两种入口协议下的离散时间Erlang消失系统Geom/Geom/c/c,通过对系统的重构,建立新模型,分别得到两种入口协议下的稳态分布、PGF、平均队长和损失率的表达式,并进行了新旧模型的数值比较。 Discussed two kinds of entrance under the agreement of the java. awt. geom Erlang disappear in discrete time system/the java. awt. geom/c/c, through the reconstruction of system, establish the new model, separately by two entry agreement under the steady state distribution, PGF, average captain and loss rate of expression, and numerical comparison of old and new model.
55109 通过比较得到,新旧模型队长的计算方法,损失率不同,但是状态转移矩阵,PGF的表达式相同。 Captain, is obtained by comparison of old and new model and the calculation method of loss factor are different, but the state transition matrix, same PGF expressions.
55110 最后,在新模型下对两种不同入口协议进行了对比,得出两种协议下顾客的损失率随到达率增加而增大;随服务台个数和服务率的增加而减小;两种协议下顾客的平均队长随服务率的增加而减小,随到达率和服务台个数的增加而增大;同一参数下,有直接入口的损失率低于有延迟入口的损失率,有直接入口的平均队长低于有延迟入口的平均队长。 Finally, under the new model compares two different entry agreement, it is concluded that two kinds of protocol under customer loss rate increases with increasing arrival rate;With the increase of the number and service desk service rate decreased;Two agreements under the customer's average captain decreases with the increase of the service rate, increases with increasing of the arrival rate and the number of the front desk;Under the same parameters, there is a direct loss rate is lower than with a delay of a gateway loss rate, there is a direct entry of captain on average is below the average captain has delayed entry.
55111 针对横截面数据的复杂装备费用预测问题,由于主要参数比较相似的装备系统其研制费用往往趋同,提出了横截面数据的"相似信息优先原理"。 Complex equipment costs for cross section data prediction problem, due to its main parameters are similar equipment system development costs tend to converge, puts forward the cross section data of "similar information priority principle".
55112 分析新研装备与以往装备的相似度,按照指标信息的相似度区分横截面信息的优先次序。 Analysis of new grinds the similarity of equipment and equipment, according to the degree of similarity index information to distinguish the cross-sectional information priorities.
55113 用归一化的相似度作为加权最小二乘法的权重,通过实例建立相似信息优先的回归模型,并与其他方法的结果对比,结果表明本文的方法具有更高的预测精度,相似信息优先的多元回归模型充分反映了相似信息的规律。 With normalization of similarity as the weight of the weighted least square method, through the establishment of similar instance information priority of regression model, and compared with the results of other methods, the results show that the method has higher precision of prediction, similar information priority of multivariate regression model fully reflects the law of the similar information.
55114 为了分析温度变化对摆式陀螺寻北精度的影响,建立了陀螺悬带随温度变化影响寻北精度的数学模型,在高低温不同条件下进行了仿真实验。 To analyze temperature change on the accuracy of pendulum gyro find north, established the gyro hanging belt with the mathematical model of temperature affected the accuracy of north found in high and low temperature simulation experiment was carried out under different conditions.
55115 首先,根据热膨胀公式得出了悬带扭转系数随温度变化关系,由此建立了零位改正系数受温度变化影响的数学模型。 First of all, according to the formula of thermal expansion coefficient of the suspension with torsion is obtained with the temperature change, thus established the zero, the mathematical model of correction coefficient affected by temperature changes.
55116 然后,在悬带扭力零位不发生改变的前提下,分跟踪和不跟踪两种情形分析了陀螺寻北精度受到的影响。 Then, in the suspension with torsion zero without change, tracking and analysis of the two circumstances do not track the gyro north find precision is affected.
