  • Development and evaluation of an intelligent fleet management system for city logistics

    Proceedings of the 41st Hawaii International Conference on System Sciences (HICSS), January 7-10, 2008.

    The routing plan of a delivery fleet is usually developed a priori and provides an optimal (or near optimal) way of serving customers by taking into account certain constraints, such as delivery time windows. However, such plans may not cope adequately with the dynamics of a city logistics environment, in which unexpected events (e.g. traffic congestions) often occur during delivery execution. We present the development and evaluation of a real-time fleet management system that handles such unforeseen events. The system monitors the delivery vehicles in real time, detects deviations from the initial distribution plan, and adjusts the schedule accordingly by suggesting effective rerouting strategies. The system has been tested in simulation environment and in real-life cases and the results show that delivery performance is enhanced significantly and customer satisfaction is improved.

  • Estimation of Target Selling Price in New Product Development

    Minis, I., Kourounis, T.
    Proc. of the 2006 ASME International Design Engineering Technical Conferences & Computers in Engineering Conference, September 10-13, 2006.

    This paper proposes a systematic way of estimating the target selling price of a new product, at the early design stages of its development. The main objective of the method is to establish a robust price estimate strictly according to the market perspective. Based on concepts inspired by House of Quality, the proposed method uses the customer requirements (CR), as well as the perceived satisfaction of each CR, and estimates the selling price based on the price of competitive products. Using this price estimate and subtracting profit and overheads, the product target cost (material and labor) can be estimated, providing a critical input to the new product development team. The research focuses on simple assemblies, an area in which target costing is not yet widely used.

  • Service Attribute-Process Matrix: A Tool for Designing and Managing Services

    Gliatis, V., Minis, I.
    IEEE/SSSM'06.

    The growing importance of the service economy during the last 40 years has raised the need for new tools for designing and managing services. As a result, several authors have developed service classification systems, in order to better understand the nature of service operations and provide methods and tools to improve service efficiency and quality. This paper exploits the work resulting from service classification systems and identifies the principal attributes to be considered in service management. The tool introduced for this purpose is the service attribute-process matrix (SAPM), which uses selected results from existing service classification schemes to investigate the importance of the significant service attributes to major processes of the service life cycle.

  • Checking the Consistency of the Rail Resources with the Railway Demand: The Athens 2004 Olympic Games

    Tsamboulas, D. and Minis, I.
    the 10th WCRT Conference, 2004.

    Transport operations constitute a critical prerequisite for the successful staging of a special event. Operations are more challenging to manage for those events that are infrequent and last for several days. In this case, the requirements for unconditional success, coupled with the uncertainties involved, necessitate robust contingency planning. This paper presents a methodological process for developing the transport-related contingency plans to address pre-identified emergencies in major events, such as the Olympic Games. War Games are proposed to test the resulting contingency plans and train the staff involved in plan implementation. The application of the methodological process to the Athens 2004 Olympic Games is presented, in which transport services were offered to over 50 000 members of the Olympic Family, 150 000 staff and volunteers, and 3.8 million spectators over a period of more than two weeks.

    Abstract
    Transport operations constitute a critical prerequisite for the successful staging of a special event. Operations are more challenging to manage for those events that are infrequent and last for several days. In this case, the requirements for unconditional success, coupled with the uncertainties involved, necessitate robust contingency planning. This paper presents a methodological process for developing the transport-related contingency plans to address pre-identified emergencies in major events, such as the Olympic Games. War Games are proposed to test the resulting contingency plans and train the staff involved in plan implementation. The application of the methodological process to the Athens 2004 Olympic Games is presented, in which transport services were offered to over 50 000 members of the Olympic Family, 150 000 staff and volunteers, and 3.8 million spectators over a period of more than two weeks.
