It uses very short pulses, so that the spectrum of the emitted signals may spread over several GHz and data rates is very important. In this paper, a Vehicle-Infrastructure (V2I) communication system based on the UWB-OFDM (Multi-Band Orthogonal Frequency Division Modulation) technology is studied and analysed. In this application, two parameters are analysed the channels effect and the data rate. The performances of the proposed solution are evaluated in terms of Bit Error Rate (BER) and data rate in AWGN and Rayleigh channels. The results simulations show that the UWB-OFDM system gives a good result in terms of BER and it is necessary to adapt the data rate to the channel propagation environment.","PeriodicalId":324478,"journal":{"name":"2011 4th International Conference on Logistics","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115415886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

That decision is a multicriteria problem and a complex process that requires the use of multiple quantitative and qualitative criteria, often in conflict.

The aim of this paper is to present a comparative study between the selection of suppliers of goods and that of suppliers of services such as the logistics services, in terms of criteria and methods.","PeriodicalId":324478,"journal":{"name":"2011 4th International Conference on Logistics","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116944050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this paper is to analyze the influence of the postponement in an enterprise production system with make-to-stock and with seasonal demand. The research method used was a case study, the instruments of data collection were semi-structured interviews, document analysis and site visits. The research is based on the following issues: Demand Management which can be understood as a practice that allows you to manage and coordinate the supply chain in reverse, in which consumers trigger actions for the delivery of products. The Supply Chain Management is able to allow the addition of value, exceeding the expectations of consumers, developing a relationship with suppliers and customer's win-win. The Postponement strategy must fit the characteristics of markets that require variety of customized products and services, lower cost and higher quality, aiming to support decision making. The production system make-to-stock shows enough interest to organizations that are operating in markets with high demand variability.","PeriodicalId":324478,"journal":{"name":"2011 4th International Conference on Logistics","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117244380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
