At present, the industry of logistics is developing towards profession and socialization. The logistics distribution plays a very important role in the enterprises related, and transportation problem is the key problem of logistics distribution. Therefore, it is meaningful to study on transportation efficiency.Aimed at the problem of low efficiency in transportation and real time distribution in logistics transportation industry, this article introduced ITS into the construction of modern transportation system. Based on detailed analysis of requirement of logistics operation, this paper constructed a new vehicle operation system, which is one that adopted GPS as vehicle positioning means and GPRS as wireless data transmission means. And the design of terminal in vehicle and monitoring center was studied. The main researches in this paper are as follows:1) This paper undertakes overall analysis of ITS and logistics transportation system, such as theoretic research development status at home and abroad. All these offer foundations for research of the thesis.2) On the basis of analysis of traditional transportation operation, some melioration were put forward, and a new transportation system was carried out: the construction of vehicle monitoring center, and real time communications between drivers and monitoring center by installing terminal in vehicle, the circumstances of vehicle on way are in control all the time; drivers get the best route under the assistance of system, and also some integrate information service, such as weather, road conditions, serving section, etc; clients can acquire information inquiry service by internet.3) Divide the system into three parts: terminal in vehicle, monitoring center and wireless correspondence network. Design hardware structure of terminal in vehicle and monitoring center, select short message of GSM mobile correspondence network to realize correspondence between vehicle and monitoring system, and design the data base of monitoring center.4) Realize simulation of logistics transportation through flexsim modeling. The thesis select the process of vehicle on way as simulation object, compare traditional transportation and logistics transportation based on ITS, the result shows that logistics transportation based on ITS can efficiently reduce transportation time and improve transportation efficiency.This research is used for references to the logistics transportation industry, which is able to optimize resources and decrease logistics cost so as to improve the competition ability of the logistics transportation enterprises. With the research deepen, the function of vehicle navigation will be more perfect, more and more navigation equipment will be installed to transportation vehicles, which is more helpful to improve the efficiency of logistics enterprises.

That is Peruvian reality2007-05-22 10:06:51 by --
I lived in Peru for four years. The first few days, I kept seeing people everywhere who seemed to be selling cell phones and calculators. Well, it turns out that money changing takes place everywhere. You go up to anyone of these people and ask the exchange rate. You are well advised to check with several. The person will show you on his calculator how much Peruvian currency you'll get. If OK, you give him your dollars and he gives you Peruvian currency. The cell phone is for him to check with his boss on the exchange rate, which moves constantly.
I found that most of these guys were honest, and the rate was consistent all over. It's a way that normal people can make enough money to support themselves (there is a small difference between buy and sell rates that gives them...
Traveling, need to convert Dollars ($) to Yen,2010-12-02 14:41:57 by dollarstoyen
Whats the best way to do it. A few questions...Question: 1. My bank offers free exchange from dollars to yen, but the current rate right now is about 79Y to a $, according to online calculator, the exchange rate is 84Y to a $, I'm not sure what the discrepancy is.
2. According to the Narita airport page the exchange rate using a travelers check is 83.15Y to a $, much better than 79Y at my bank. Does this seem to be the norm or is there actually a few Yen charge at the airport in Tokyo?
3. I am trying to figure out the best way to exchange money in Japan. I don't mind taking travelers checks but if it works out to the same amount I will probably...
