通过CRM系统分析、本公司需求分析及考察CRM的一般系统与实际业务流程关系，确定本公司CRM系统设计定位于基于部门应用、运营与分析并重。并在此系统设计目标定位下，确定系统流程，设计功能模块，并努力面向部门协作与数据挖掘。-Through the CRM system analysis, needs analysis the Company and the inspection of the general system CRM business processes and the actual relationship between the CRM system to determine the design of the Company located in sector-based applications, both operations and analysis. And targeting this system under design, the system processes, the design of function modules, and the efforts for collaboration and data mining sectors.

好多关于学生选课的毕业设计 很好的 大家尽量下吧-many of the students graduating classes of good design as far as possible under it

数字复接就是把两个或两个以上的支路数字信号按时分复接方式合并成单一的合路数字信号。-Digital multiplexer is to slip two or more digital signals in time division multiplexing access method into a single co-channel digital signals.

PPP挑战握手认证协议(CHAP)，PPP【1】提供了点到点链路传输多协议数据报的标准方法。 在PPP中也定义了一种可扩展的LCP，允许协商认证协议，从而可以在进行网络层 协议传输之前对对端进行认证。 本文定义了一种PPP认证方法，该方法利用随机“挑战”和依据“挑战”和密钥 计算出的加密哈希“应答”来完成认证。 -PPP Challenge Handshake Authentication Protocol (CHAP), PPP [1] provides a point-to-point link multi-protocol data transmission of standard methods. In PPP also defines a scalable LCP to allow consultations authentication protocol, thereby conducting transmission network layer protocol before the end-to-end authentication. This paper defines a PPP authentication methods, The method using random "challenge" and the basis for "challenge" and calculated key encryption Hash "responsive" to complete certification.

摘要:实战条件下如何评价短波跳频通信系统的抗干扰性能是构建短波跳频通信系统的重要环rr-}J。由于不 能得到精确的指标评价值，采川组合赋权法给出了系统抗干扰性能的评价算法已经不能适川。给出了一种模糊综 合评价方法，该方法有如下优点:为避兔专家赋指标权值的卞观随意性，将德尔菲(Delphi)法和层次分析法(AHP)相结合来确定指标权值 为了便于专家较准确地作出评判，给出了指标评价等级，并利川模糊评价法给出指标评价矩 阵，最后得到评价结果。评价实例表明了该方法的有效性。 -Abstract: how to assess the actual conditions of short-wave frequency-hopping communication system anti-jamming performance is short-wave frequency-hopping communication system to build an important ring rr-) J. Can not be accurate due to evaluate the value of mining Kawasaki combination weighting approach gives a systematic evaluation of anti-interference performance can no longer be appropriate algorithm Chuan. This paper presents a fuzzy comprehensive evaluation method that has the following advantages: In order to avoid the rabbit experts give the right indicator of the value of randomness Bian concept will Delphi (Delphi) and Analytic Hierarchy Process (AHP) to determine the combination of the right indicators value in order to facilitate t

设有n项独立的作业{1,2,…, n},由m台相同的机器加工处理。作业i所需要的处理时间为ti。约定：任何一项作业可在任何一台机器上处理，但未完工前不准中断处理；任何作业不能拆分更小的子作业。多机调度问题要求给出一种调度方案，使所给的n个作业在尽可能短的时间内由m台机器处理完。设计算法。 -Stand-alone operation with n items (1,2, ..., n), by m units the same machine processing. Job i the processing time required to ti. Convention: any one job can be processed on any machine, but does not pre-completion are not allowed to interrupt processing any operation can not be split smaller sub-operations. Multi-machine scheduling problem requires paper, a scheduling program, so that given the n-operation in the shortest possible time processed by m machines. Design algorithms.
