This paper presents a web-based software tool for the commute carpooling problem, whose main characteristics are the following: 1) besides suggesting a matching between the users, the system provides the expected schedule and route for their trips; 2) the users are informed immediately in case of delay or changes via e-mail or via short messages; 3) the software estimates the costs and benefits for each user; 4) the use of the system is restricted to the employees of given companies. The software has been tested in a case study regarding the Politecnico di Milano university students, running simulations on possible service scenarios. The first suggestions for the company mobility manager of Politecnico di Milano are to focus more on incentives for park and ride season tickets than on parking spots reserved to car-poolers at the campuses and to promote – since the beginning – a carpooling service shared by all the universities of Milan.","PeriodicalId":365774,"journal":{"name":"International Journal of Services Sciences","volume":"158 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133897325","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}

In fact, it is dependent on the transportation network quality and place structure; it influences our daily moving and our mobility decisions. In this paper we adopt the fuzzy spatial network Voronoi diagram (fuzzy-SNVD), an approach based on fuzzy arithmetic and graph theory, in order to evaluate the fuzzy Voronoi geographical accessibility to its generators (station, public facility, equipment, etc.). This evaluation and its cartographic representation occupy a key position among the necessary tools which can give decision makers effective assistance support in the transport planning process. Indeed, we propose within this framework two algorithms which allow calculating the fuzzy-SNVD and which consist in assigning each Voronoi generator to its closer nodes of the graph modelling a real spatial network. This assignment of the nodes is based on the comparison of the weights of the shortest traversed paths, which are considered fuzzy numbers representing, in a way more faithful to reality, the travel times, speeds or all values describing moving on the transport network.","PeriodicalId":365774,"journal":{"name":"International Journal of Services Sciences","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126098378","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}

Banks can face financial risks from borrowers defaulting on the repayment of their loans because of fines imposed for poor environmental performance. Indeed, current environmental regulations can make banks liable for environmental damage caused by borrowers. Banks, therefore, aim to minimise these risks with the introduction of environmental criteria into their lending decision-making. These criteria are often based on firms' environmental reports, compiled on a voluntary basis. However, the lack of a common reporting baseline may mean that different information is provided by different industries and countries, a fact that prevents banks from estimating the full risk premium of environmentally vulnerable firms in a standardised and comparable format. Thus, this paper aims to propose a new methodology for measuring the environmental risks of firms to meet the requirements of the financial sector. Specifically, this methodology aims to standardise and quantify this information in an effort to reveal both to the banks as well as interested stakeholders the true environmental risk arising from firms' operations.","PeriodicalId":365774,"journal":{"name":"International Journal of Services Sciences","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121893435","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}

A multiple media usage was found to be more popular than a single medium usage. Factors that affected both primary and complementary media selection were investigated. As a result, social influence was identified as the most important factor for the primary medium selection followed by a rational factor and environment factor. The study revealed that both rational and social influence factors were closely related for a primary medium selection; however, social influence had almost no effect on selecting complementary media. The findings of this study are not only useful to guide risk aversion in media selections in IT and service industries, but also potentially effective in media selections in various remote working fields.","PeriodicalId":365774,"journal":{"name":"International Journal of Services Sciences","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132894726","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}

Many of them relate to the traditional goods without being concerned with an activity in particular. Others on the contrary are targeted on a precise sector. All these experiments are not taking into account the total organisation of goods distribution inside the city. Such an approach is undoubtedly difficult in large agglomerations but can be much more easily considered in medium sized ones. That will not only make it possible to reduce the generation of the side effects but will especially allow economic gains for the actors. Obviously, local authorities have several available actions of regulatory measurements for implementation, but they can enlarge with other types of actions and tools in a concerted approach with the freight actors. In this article, we propose a methodology to optimise urban freight transport from a systemic point of view. It has been developed considering the experiments in progress in La Rochelle, within the European project SUCCESS of the CIVITAS programme.","PeriodicalId":365774,"journal":{"name":"International Journal of Services Sciences","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126259214","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 questionnaire seeks responses on four main factors: profile of the users, transportation behaviour of users, willingness to use carsharing and preferences for new carsharing stations in La Rochelle. The target groups surveyed were city residents, tourists, businessmen, students and city transport organisations namely city of La Rochelle, CdA La Rochelle and Conseil Generale du Charente Maritime. A total of 500 questionnaires were distributed in-person and a response rate of 81.4% was received. The findings of this study reveal useful information on the feasibility of the offer, user motivations and service design aspects for the new carsharing system. It was found during the study that appropriate marketing strategies and awareness campaigns are required to inform people about carsharing. Other areas of improvement are ensuring availability of vehicles at times, easy access to carsharing stations, easy return procedure for vehicles after use, low trip costs and providing vehicles suited to user needs. These findings have strengthened the need for a new carsharing system in the city and have identified appropriate operational factors for its implementation.","PeriodicalId":365774,"journal":{"name":"International Journal of Services Sciences","volume":"121 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128098666","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}

One way an operator can improve its operating efficiency and quality is through continuous monitoring of its operations with key performance indicators (KPIs). Information and communication technology (ICT) can solve the monitoring problem cheaply, efficiently and effectively via the internet. The University of Rome Centre for Transport and Logistics (CTL) has implemented a prototype ICT platform to conduct a pilot study on the daily distribution service in Rome of a transport operator with a small fleet. The pilot has highlighted the reduced cost of the investment and the ease of collecting relevant data and using them to measure performance, but also the remaining barriers to the practical use of ICT.","PeriodicalId":365774,"journal":{"name":"International Journal of Services Sciences","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115340344","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}

This framework involves development of innovative dynamic risk and uncertainty analysis methods known as quality function deployment. Instead of simply computing the weight of emergency planning criteria, we used rule-based expert system to handle the interdependency among the criteria. The expert system with composite rules is encoded into a Boolean satisfiability problem, which can be solved by a quadratic unconstrained binary optimisation method. We also discuss the approach based on the use of the visualisation tools by integrating with GIS and other information support systems. In this respect, this proposed approach completely changes the current practice of emergency management planning.","PeriodicalId":365774,"journal":{"name":"International Journal of Services Sciences","volume":"251 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122534450","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}
