基于HLA的舰载火控系统的仿真研究

以HLA（High Level Architecture）为计算机仿真标准,对舰载火控系统建立了各联邦成员仿真模型,并初步探讨了舰载火控系统对目标实行攻击控制的能力,给出了采用HLA技术对新型舰载火控系统进行效能评估的技术途径,为海上作战的研究提供了一个仿真环境.整个仿真系统是一个联邦,由5个联邦成员组成,各联邦成员之间通过发送交互达到攻击目标的目的.仿真的结果表明,指挥仪可以根据目标、舰艇、导弹的信息来控制是否对目标实行攻击,达到实时交互仿真的效果.     

Selection of a pull production control policy under different demand situations for a manufacturing system by AHP-algorithm

A multistage serial production system is considered in the present paper. A generalized model has been developed with the use of probabilistic demand situations for the end product. The demand situations considered are binomial, exponential, lognormal and Poisson. These demand patterns are used as input parameter for various production control policies. The output values for performance parameters are obtained by simulation. The production policies analyzed are Kanban, CONWIP and Hybrid as alternatives for controlling the engineering manufacture. In the presence of several performance measures, it often becomes difficult for the management to select the most appropriate policy. Analytic hierarchy process (AHP) has been implemented for the purpose of selection. Computational results have been reported along with the sensitivity analysis after designing and conducting various experiments.
