    New Social Media in Qualitative Research: Challenges and Recommendations

    Wednesday 25 November 2015

    Traditionally the main source of data for qualitative researchers has been the face-to face interview. However, with the emergence of new social media (NSM), the main source of qualitative data for qualitative researchers in the future is likely to be the Internet.

    A Hadoop-based Data Processing Platform for Fresh Agro-Products Traceability

    Wednesday 25 November 2015

    Wireless sensors on cold chain containers generate huge volume of real-time data that needs efficient processing for decision making, e.g. shelf life prediction due to quality decay. This paper introduces a Cloud Computing Traceability Platform (CCTP) which is constructed on top of Hadoop cloud computing framework.

    Flexibility Analysis on a Supply Chain Contract using a Parametric Linear Programming Model

    Thursday 12 November 2015

    This research work builds on existing knowledge in the field of parametric Linear Programming (pLP) and proposes a continuous mathematical model that considers a multi-period Quantity Flexibility (QF) contract between two independent agents, a customer (buyer) and its supplier.

  • Research Seminar

    Understanding behaviour in problem structuring methods interventions with activity theory

    Thursday 29 October 2015

    OR interventions, particularly problem structuring methods (PSM) interventions, are events that cannot be understood by conventional methods alone. This talk outlines theoretical and methodological concerns that need to be appreciated in studying PSM interventions.

    Multi-Attribute Value Theory used to rank the performance profiles in the UK Research Excellence Framework

    Wednesday 28 October 2015

    The present UK Research Excellence Framework (REF) used for assessing the quality of research in UK higher education institutions does not provide a final ranking but only a percentage profile for each department of UK institutions across performance categories ordered from most prominent (4*) to least prominent (1*), and unclassified (U/C; 0*).

  • Research Seminar

    MacBethSort: a multiple criteria decision method for sorting strategic products

    Thursday 1 October 2015

    Efficient companies need to know which their strategic products are. For this purpose, the ABC classification based on the item’s value was developed and was used for a long time. Later, it was recognised that several other criteria need to be considered and multi-criteria ranking methods were applied. However, the classes have always been defined based only on a relative proportion.

    Multi-Attribute Value Theory used to rank the performance profiles in the UK Research Excellence Framework

    Wednesday 28 October 2015

    The present UK Research Excellence Framework (REF) used for assessing the quality of research in UK higher education institutions does not provide a final ranking but only a percentage profile for each department of UK institutions across performance categories ordered from most prominent (4*) to least prominent (1*), and unclassified (U/C; 0*).

  • Annual Research and Innovation Event

    CORL 2nd Annual Research and Innovation Event

    Friday 17 July 2015

    The event aims to bring together business partners and experts in Data Analysis and the Science of Better Decision Making to identify challenges in Logistics and Transport, Inventory Management and Forecasting, Renewable Energy, Reverse Logistics and Supply Chain, Maintenance and Reliability, and discuss potential collaborations with a view to improving decision making in business.

  • Research Seminar

    Exploring Decision Maker Preferences for Solving Stochastic Multiobjective Programming Problems

    Thursday 4 June 2015

    Solving Stochastic Multiobjective Problems (SMP) involves always transforming each stochastic objective of the problem into a deterministic one. This transformation is carried out by using some statistical characteristic of the random variables involved in the problem. Different concepts of satisfactory solutions for SMP problems will be presented.

  • Research Seminar

    Modeling and Optimal Control Applied to Dengue Vector

    Thursday 21 May 2015

    Some studies have been performed in order to optimize controls of the mosquito population that transmits dengue. Optimization techniques and numerical results of this problem will be given and discussed in this presentation.

  • Workshop

    Intelligence provides Autonomy: The Era of Unmanned Vessels

    Wednesday 20 May 2015

    This workshop will highlight the importance and place in the market for autonomous vessels; the need for continued research and the expected technology growth in the future. It aims to bring together leading academic scientists, researchers and industrials to exchange and share their experiences and discuss the most recent innovations, the technology advances and the practical challenges to be encountered in this awe-inspiring field.

  • Research Seminar

    Mathematical Models for the Territorial Re-organization of Public Services

    Thursday 7 May 2015

    Location decisions represent a critical element in the strategic planning of services as they can have a strong and lasting impact on their operational and logistic performance. A Facility Location Problem is aimed identifying the optimal position to assign to one or more structures, in a given space, in order to satisfy a demand (actual or potential) coming from a set of customers. Mathematical models for exploring re-organization decisions in non-competitive contexts and applications arising in real-world situations will be described in the presentation.

  • Conference

    The 12th ESICUP meeting, Portsmouth, United Kingdom

    29 March - 31 March 2015

    EURO Special Interest Group on Cutting and Packing (ESICUP) gathers practitioners, researchers and Operations Research educators with interests in the area of Cutting and Packing. The purpose of ESICUP is to improve communication among individuals working in this field.

  • Breakfast Briefing

    Decision Aiding Algorithms and Software of Tomorrow

    Friday 13 March 2015

    The University of Portsmouth is bringing together experts in decision analysis from the Centre for Operational Research and Logistics (CORL). In this breakfast briefing you will have access to these experts who will talk through practical business examples of decision analysis being used to enhance business operations.

    Train Scheduling and Rescheduling in the UK with a Modified Shifting Bottleneck Procedure

    Thursday 26 February 2015

    Dr Banafsheh Khosravi will introduce a modified shifting bottleneck approach to solve train scheduling and rescheduling problems. The problem is formulated as a job shop scheduling model and a mixed integer linear programming model is also presented. The shifting bottleneck procedure is a well-established heuristic method for obtaining solutions to the job shop and other machine scheduling problems.

    Integration of Matheuristics in Radiotherapy Planning System

    Thursday 19 February 2015

    The Radiotherapy Planning is a task that can be treated and optimised by Operational Research techniques. The planning involves problems that consist in determine the machine position (beam directions), the dose distribution and the multileaf collimator opening. In this talk, the speaker will present three methodologies to solve the dose distribution and beam directions problem: the exact method of Branch and Cut, the matheuristic GArad and the matheuristic TSrad.

  • Research Seminar

    Heuristics and Integer programming models for two applications in irregular shaped bin packing problems

    Thursday 29 January 2015

    Prof. Julia Bennell will present a hybrid algorithm that is a constructive heuristic that determines the relative position of pieces in the bin and guillotine constraints via a MIP model. The presentation will address the two-dimensional irregular shape bin packing problem. The first application arises in the glass cutting industry, for example, the cutting of glass for conservatories and as a result the packing must respect guillotine constraints. The second application is found in the ceramic industry, where pieces can be of any arbitrary shape.

  • Channel MOR Workshop
