銀行排隊(duì)的數(shù)學(xué)模型的實(shí)現(xiàn) 問題: n銀行有n個(gè)窗口對(duì)外營業(yè),每個(gè)窗口一次只能接待一個(gè)客戶 n客戶的到達(dá)時(shí)間和處理業(yè)務(wù)的時(shí)間不同(可隨機(jī)產(chǎn)生) n利用鏈表隊(duì)列模擬總的處理過程和處理時(shí)間 n假設(shè) n不允許插隊(duì),不同客戶的交接時(shí)間忽略不計(jì) 策略I: 策略 客戶先選擇無人窗口辦理 如果沒有,就選擇人數(shù)最少的窗口排隊(duì) 討論 人數(shù)最少未必能最快得到處理 如果客戶發(fā)現(xiàn)其他窗口的排隊(duì)人數(shù)少于本窗口認(rèn)輸,他是否排過去 策略II: 策略 客戶到達(dá)后取號(hào)等待 哪個(gè)窗口處理完畢,即處理下一個(gè)號(hào)的客戶 討論 某些客戶的等待時(shí)間會(huì)減少? 總等待時(shí)間是否會(huì)減少? 策略III: 策略 專門開一個(gè)窗口處理大客戶 大客戶與其他客戶選號(hào)系統(tǒng)不一樣 大客戶的處理時(shí)間超過某個(gè)閥值 若大客戶窗口無客戶可暫時(shí)處理其他客戶 討論 哪些客戶的等待時(shí)間會(huì)減少? 總等待時(shí)間是否會(huì)減少

In term project, we will take the baseline JPEG codec in ARM-based platform system as an example to practice the design flow in SoC. We divide the project into three parts, and the goal of each part is described as follow. Part I: Design a baseline JPEG software codec in C/C++ and port it to ARM core,(ARM7TDMI, ARM720T, or ARM922T.) Part II: Make use of virtual prototype to integrate/verify the hardware and software. Part III: Verify your soft IP in target environment.

This book covers the fundamental concepts of data mining, to demonstrate the potential of gathering large sets of data, and analyzing these data sets to gain useful business understanding. The book is organized in three parts. Part I introduces concepts. Part II describes and demonstrates basic data mining algorithms. It also contains chapters on a number of different techniques often used in data mining. Part III focusses on business applications of data mining. Methods are presented with simple examples, applications are reviewed, and relativ advantages are evaluated.
