With regard to the practical problem that improving some kind of existing rocket launcher to the launcher that using canister , the general project and some detail design which based on the performance and technology in existence are given in this paper 本文针对某型号火箭炮改为箱式发射这一实际问题，以该火箭炮现有的性能特点、技术水平和未来发展的趋势为依据，进行了总体方案和部分机构改进方案的设计，给出了四种可行的总体方案。
New developments in decision theory , artificial theory and dynamic analysis method are applied to evaluation the possible projects . the main contents in this paper are included as follows : first , has improved an format reasoning method based on multiple attribute utility model and knowledgebase theory ; second , has proposed complex utility model by improving the theory of multiple attribute utility ; third , has presented a kind of weapon intelligent decision support system , based on the complex utility model and developed with com / dcom criterion ; forth , this paper also has build the dynamic simulation model for long - rang multiple tube rocket launcher system , and the tire dynamic model has applied in the rocket launcher system dynamic simulation model ; fifth , through building the rocket - launcher contact model , this paper has analyzed the dynamic forces between the rocket and launcher ; finally , this paper has build the evaluation model of the project about improving existing rocket launcher to the launcher that using canister , and get the conclusion through using the widss . the studies in this paper not only proposed scientific warrant to the choice of projects in this pre - studied national defense task about improving existing rocket launcher to the launcher that using canister , but also can give other studied tasks with decision supported 主要内容包括：在总结决策分析与专家系统规则库技术的基础上，提出了融决策分析与专家系统规则库技术于一体的形式化推理机制，该机制能有效的将定量计算和定性知识融为一体，将规范的决策分析解题过程与专家系统特有的演化推理方法有机结合起来；在多属性效用理论的基础上，建立了一般形式的复式效用模型，并实用化了全相关乘式效用模型，提供了较完善的通用建模、分析和解释功能：引入了com dcom组件技术，开发了基于组件的widss系统，该系统基于形式化推理机制，易于扩展，能够面向多种决策问题，具有较强的通用性；建立了远程多管火箭炮全炮动力学仿真模型，将充气轮胎动力学模型、轮胎和路面的相互作用模型运用于多管火箭炮动力学仿真计算中；利用碰撞接触理论，对火箭弹在定向器管内的运动受力情况进行了仿真计算；建立了远程多管火箭炮箱式发射改进方案模型，并利用动力学仿真计算结果在widss系统中进行了方案性能评估。
This paper is an important part of the pre - studied national defense task in the tenth five year plan about the study on improving existing rocket launcher to the launcher that using canister . this paper presents the whole procession of the comprehensive evaluation for the possible projects by using the weapon intelligent decision support system ( widss ) . and the dynamic analysis and results of the comprehensive evaluation are given 在十五期间重点预研课题“火箭箱式发射技术”中，我们利用武器智能决策支持系统( weaponintelligencedecisionsupportsystem ，简称widss )在所调查的专家知识的基础上生成远程多管火箭炮箱式发射设计方案评价系统，并运用虚拟样机技术对现有远程火箭炮系统和箱式改造方案进行建模和动力学仿真计算，将仿真结果输入评价系统中进行方案性能评价，为课题的方案选择和确定提供了科学的依据。
