Transportation policy formulation as a multi-objective bilevel optimization problem

Abstract: In this paper, we consider multi-objective bilevel optimization problems in the context of transportation policy formulation. In such problems, an authority managing a network of roads is the leader that tries to solve the problem by taking into account the possible actions of the network users who are considered as the followers. In the presence of multiple objectives, the resulting solution set is a Pareto-optimal frontier that consists of optimal decisions of the leader and corresponding optimal responses from the follower. The authority's objectives are to maximize its revenues through tolls and minimize the pollution levels. The network users' objectives are to minimize travel cost and travel time. In addition to accommodating multiple objectives at both levels, the benefits of the proposed formulation is that it allows incorporating various real-world complexities, like admitting complex road network topologies and allowing the modelling of several road user classes with different preferences. A recently proposed algorithm for multi-objective bilevel optimization is used to solve the problem.

Impact of customization over software quality in ERP projects: an empirical study

Abstract: Enterprise resource planning (ERP) systems are recognized as management information systems that streamline business processes of an enterprise. Delivering ERP software to meet functional needs of an organization with acceptable level of quality is a challenge due to the very nature of development and deployment of this packaged software. Drawing on ISO/IEC 9126's characterization of software quality and Luo and Strong's ERP customization framework, this paper analyzes the impact of the ERP system customization on software quality of ERP. A software quality framework for ERP customization has been developed, and three sets of hypotheses have been formulated. A detailed survey was conducted for data collection. The statistical data analysis reveals that module customization does not impact ERP quality, while database and source code customizations have significant influence over ERP quality. Our findings have implications for the implementation of customized ERP in organizations.
