In the chapter two we discussed that the server would first use speed - 1 to serve customers when the system entered the busy state from the empty state, but when the server found the number of customers in the system exceeded the thresh - n during serving, after finishing the service of current customer it would use speed - 2 to serve the next customer till there is no customer. by the method of supplementary variable, l - transition and constructing vector markov, we attained the distribution of the queue length, the distribution of wait - time, the distribution of stay - time, the utility and etc. in the last part of this chapter, we discussed the optimal n * for thresh n which minimizing the cost function and we illustrate the cost function behaves for various parameter selections by a numerical study

With the trend of openness and integration of globlal economy, exchange rate is playing more and more important role in influencing the allocation of global resources. the sensitivity of the price of tradale goods to exchange rate fluctuation becomes the focus of international economics because it is a critical vector and transmitter when an economy is confronted of exogenous impact. traditional international economics theory assume that nominal exchange rate fluctuation has complete pass - through effect, namely it ’ s change will introduce proportional change of tradable goods, then it will influence such macroeconomic vector as term of trade, import and export, inflation, employment, productivity, income allocation, and so on. from a microeconomic angle, including pricing to market, innovative behavior, menu cost and sunk cost, the paper probe into the pricing model of international enterprices under floating exchange rate and testify the incomplete pass - through of exchange rate and it ’ s detailed reason, then discuss the inspiration it has on china. it ’ s believable this kind of research will play a big part in china ’ s exchange rate scheme and some macroeconomic problems such as exchange rate tranmitting channel and effects, exchange rate fluctuating behavior
傳統的國際經濟學理論認為，名義匯率的波動具有完全的傳遞性（ completepass - through ） ，即它的變化會引起同比例的進出口貿易品相對價格以及貿易品和非貿易品相對價格的變化，然後通過需求變動的支出轉移效應（ expenditureswitching ）來影響國內經濟的諸多宏觀變量，如貿易條件、進出口貿易額、通脹水平、就業量、勞動生產率以及收入分配等，本文從依市定價（ pricingtomarket ） 、創新行為、菜單成本以及沉澱成本等四個不同的微觀角度，通過對浮動匯率下國際壟斷競爭性生產廠商的定價模型具體而透徹的探討，論證了匯率的不完全傳遞性並深入分析了決定匯率傳遞彈性的重要影響因素，闡述了該理論對人民幣匯率的啟示，這樣的研究會對我國今後的匯率政策以及匯率的傳導機制、傳導效應、波動行為等宏觀經濟問題起到重要的作用。 -
