The real time performance of such algorithm in worst case is presented . under some assumptions of stochastic characteristic of tasks , a more accurate condition for os to response a real - time event before its deadline is given 本文给出了时间触发（ timetriggered ）和事件驱动（ eventdriven ）任务的改进的全优先级调度算法，并分析了最坏情况下的系统实时响应性能和基于事件统计特性的动态响应性能。
In recent years , all over the world have realized inter - operation of real - time creation and real - time response in technology of scene simulation , but all this is based on graphical workstation , it ' s still at preliminary state in research based on personal computer 近年来，国内外在视景仿真技术方面，已能够实现视景实时生成，实时响应交互操作，但大多数是基于图形工作站研究的，桌面级或基于pc机的研究工作尝处于起步阶段。
By studying the process and character of the invading behavior ids can make between security system respond in real time to the invading process and behavior . there are three kinds of realization such as software , hardware and software - hardware integration forms . it usually adopts distribution system structure composed of managing and controlling center and detecting engines 入侵检测技术通过对入侵行为的过程与特征的研究，使安全系统对入侵事件和入侵过程做出实时响应，其实现形式有软件、硬件和软硬一体三种，通常采用管理控制中心和检测引擎组成的分布式体系结构。
Supported by the 863 projects of " 2001aa411320 regional modern integrated manufacture system development and application oriented city of chengdu , deyang and mianyang " and the science and technology key project of sichuan province " the engineering configuration intelligent cad technology oriented the process of design " , this paper chiefly focus on the following : 1 . according to " framework of cooperative design system " proposed by the center of cad eng . southwest jiaotong university , the exiting range of the real - time response and the exiting forms of the real - time information are analyzed in design 本文所涉及的研究课题在国家863计划项目： “ 2001aa411320以成德绵为核心的区域现代集成制造系统开发及应用”与四川省重大科技攻关项目： “ 01gg010 - 01区域制造业信息化关键技术与应用研究”的资助下，主要进行了以下几方面的工作： ( 1 )根据西南交通大学cad工程中心提出的“协同设计系统整体框架” ，分析了其中实时响应存在的范围以及设计中实时信息的存在形式。
( 2 ) the platform lowers enterprise implementation costs . the cpc - asp is a collaborative product commerce platform being geared to the needs of information era . it can build up an audio - visual , collaborative and interactive commerce environment for enterprise and customer 协同产品定制asp平台是按asp商业模式营运的面向信息时代的商务平台，为企业建立起面向用户的，可视听、可交互、可实时响应用户需求的企业商务环境，为用户建立起可比较择优、可按需定制的用户购物环境。
After giving all - sided analysis and evaluation on kinds of memory allocation pattern , it designs rtps _ cached _ allocator , a pooled memory allocator which can decrease the overhead resulted from the general dynamic heap allocation , in order to improve the dynamic performance of a system and meet the de mand of qos predictability . a memory pool management framework , mpmf , is also shown 在全面分析总结各种内存分配模式及其优缺点与适用环境的基础上，针对实时响应系统对动态性能和qos可预测性的需求，设计实现了一个能够有效减少内存分配开销的池式分配器rtpsmachemllocator ，提出了一个内存池管理框架mpmf 。
In the automobile type and logistics information publication system , information of automobile type and parts to be assembled can be displayed on terminals set on each station , which enables ship - fitters know the car flow on the assembly line and make preparations for assembly work . the system also allows workers to send out material requirement message so that logistics department could response to the message and deliver the material to right place in proper time and by proper amount , which converts the traditional " push " mode material supply method to demand drive " pull " mode 本文研究的车型及物流信息发布系统可以在工位实时、动态地显示总装线上各工位的车型信息和零件选装信息，使装配人员及时了解总装线车流情况，提前做好装配准备；允许装配人员通过键盘提交物料需求信息；物料供应部门可以实时响应装配工位的物料请求，将物料及时、适量地送到合适的位置。
