Evaluation of Public E-Procurement Services Accessibility: A Multicriteria Approach

Abstract

This chapter focuses on the problem of accessibility of public electronic procurement (E-procurement) services. It shows some results of multidisciplinary research whose aim is to identify and test a support model for the improvement of accessibility of E-procurement systems. The chapter discusses the conceptual framework and illustrates the methodology. It examines the indexes introduced for the measurement of the Web sites' accessibility. The chapter explores the model to evaluate the accessibility of public E-procurement services. It describes five Italian public E-procurement services: ministry of finances' online purchasing, piemonte region, province of Florence, Lombardia and Liguria regions, which use the applicative supplied by Biztop and Trambus. The analysis of the Web site starts from the consideration that such a Web is a hierarchical system articulated on three levels. The first level represents the E-procurement service that is divided into a set of attributes. Each attribute is defined through a set of characteristics.
