  • TRANSit Meeting

    DeOpSyS Lab has participated in the 3rd meeting of the project entitled TRANSit "Mediterranean Intermodal Transit" held in Valencia, Spain the 28th & 29th of May 2010. The aim of TRANSit project (INTERREG MED) is to to promote intermodality and interregional cooperation between EU countries through the development and evaluation of an innovative web-platform that supports the planning of a combined freight trip.

  • The Use of Mobile Technologies in Execution Supply Chain (M.O.R.S.E)

    Project Duration:

    24 months (October 2003 - September 2005)

    Project Partners:

    Athens Economics and Business University, Planning S.A, Nikas S.A, Diakinisi S.A., Emfasis Tilematiki

    Sponsor:

    Ministry of Development General Secretariat for Research and Technology, Greece

    Scope:

    Uneven demand, more frequent and shorter order-to-shipment times, as well as stricter customer compliance requirements are the key parameters shaping twenty-first-century business practices. As a result, companies are re-examining their business processes from a business-to-business (B2B) commerce perspective in an effort to be more effective and efficient via the inclusion of mobile technologies.

    In this context the need for a new type of supply chain model is emerging. Generally speaking supply chain processes consist of two basic axes: a) planning and b) execution. In recent years supply chain planning has attracted considerable attention. As a result advanced methods and tools have emerged, including the latest integrated supply chain optimisation systems. On the other hand supply chain execution has received less attention although it forms the fore front in the B2B interactions. It is precisely this area that the proposed research is focusing upon.

    Mobile technology can play a pivotal role in enabling real-time supply chains and supporting supply chain execution. This forms the basic scope of MO.R.S.E which will embrace the design, implementation and evaluation of innovative mobile methods, applications and services in order to support efficient supply chain execution capable of delivering enhanced value to its members (starting from the supplier and reaching the end-customer). More specifically the basic goals of the proposed research project are:

    1. Identify key areas in real-time communication and decision making that can result in step improvements in supply chain execution.
    2. Develop methods and techniques to address real-time decision making in supply chain execution.
    3. Develop state-of-the art technology systems and solutions that support the above areas.
    4. Implement and test the proposed methods and systems in realistic/complex scenarios.
    5. Disseminate the project results in both the scientific and business communities as well as present the research results in international conferences and scientific journals.

    Areas that the proposed research will address include:

    1. Dynamic re-configuration of supply chain tactics based on real-time demands and needs driven by the customers or other external factors (road congestion, emergencies, etc).
    2. Automation of Reverse logistics. Improved response to unpredicted reverse logistics customer requests such as return of damaged goods. This will necessitate extensive ERP-truck connectivity.
    3. Optimal truck utilisation in inter-city transport.

    In order to address these issues successfully, our team combines the strengths of basic research institutions (Athens University of Economics and Business, University of the Aegean), along with a system development company (Emphasis Telematics), a logistics management consultant (Planning S.A) and strong end-user base (Diakinisis, Nikas).

  • Using RFID Technology for Real-Time Logistics Management of Dried Figs: Insights from a Greek Union of Cooperatives

     

     Zeimpekis, V., Minis, I.

    Proceedings of the 4th International Workshop on Freight Transportation & Logistics (ODYSSEUS 2009, Cesme, Izmir, Turkey, May 26-29, (electronic proceedings), 2009.

    The logistics management of fresh produce and fruits constitutes an important area of the agrifood supply chain, due to the perishable nature of the products, as well as certain legislative requirements regarding traceability from the field to the supermarket shelf. Radio Frequency Identification (RFID) technology may support a number of processes in the food logistics area, such as real-time monitoring and control, as well as data collection and information provision. In this paper, we present the design, and implementation of an intelligent RFID-based information system for real-time management of dried figs. A systematic method is also proposed to fine tune this and other RFID based systems. We have tested the proposed system in a Greek Union of Cooperatives (SYKIKI Coop) of fig producers and demonstrate how RFID technology may improve warehousing operations, increase customer service through online product traceability, and reduce operational costs.

  • An Intelligent Fleet Management System for Real-Time Courier Services

    Zeimpekis, V., Ninikas, G., Athanasopoulos, T., Minis, I.

    Proceedings of the 23rd Conference on Operational Research (EURO XXIII), Bonn, Germany, July 5-8, 2009. 

    The need for higher customer service and minimization of operational costs led many courier companies to seek innovative systems for managing customer requests that occur during the planning and/or the execution of daily deliveries. This paper presents the design and implementation of an innovative fleet management system that handles in a dynamic manner the requests that arise during delivery execution and at the same time routes effectively deliveries that are planned in a multi-day framework. The proposed system is tsted in real-life scenarios in a Greek courier operator.

  • Design and Implementation of a Real-Time Fleet Management System for a Courier Operator

    Ninikas, G., Athanasopoulos, Th., Marentakis, H., Zeimpekis, V., and Minis, I.

    Proceedings of the 4th World Congress on Engineering Asset Management (WCEAM 2009), Athens, Greece, September 28 - 30, 2009.

    The need for higher customer service and minimization of operational costs has led many courier operators to seek innovative information systems for efficient handling of customer requests that occur either during the planning and/or the execution of daily deliveries. These systems address a series of operational issues that occur in the courier sector such as fleet and HR management, vehicle routing and monitoring, proof of delivery, track-and trace services, and so fourth. However, the demanding environment of the courier industry generates further operational needs that have not fully addressed by the existing systems. This paper presents the architecture of an innovative fleet management system that have been developed and implemented to a Hellenic courier operator, in order to address daily challenges and provide an integrated framework that supports effectively the dispatchers during the planning and execution of delivery schedules. The proposed system manages and allocates in real-time the dynamic requests that occur during service execution, as well as, the bulk deliveries that need to be serviced over a multiple-period (days) time horizon upon their receipt. The system has been evaluated through simulation tests and field experiments so as to ensure the robustness and interoperability of its components and assess the potential of adopting such a system in the courier industry.
