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.

串行通信MCS-51单片机内部有一个全双工的串行通信口，即串行接收和发送缓冲器（SBUF），这两个在物理上独立的接收发送器，既可以接收数据也可以发送数据。但接收缓冲器只能读出不能写入，而发送缓冲器则只能写入不能读出，它们的地址为99H。这个通信口既可以用于网络通信，亦可实现串行异步通信，还可以构成同步移位寄存器使用。-MCS-51 microcontroller serial communication within the a full-duplex serial communication port, that is, the serial receive and send buffer (SBUF), these two physically separate receiver transmitter, both can receive data can be sent data. Only read by the receiving buffer can not write, but can only write to send the buffer is not allowed to deliver, their address is 99H. The communication port can be used for both network communications, can also achieve the serial asynchronous communication, but also constitute a synchronous shift register to use.

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.
