    Effective Business Engagement: Best Practices

    Wednesday 4 November 2015, 12:00pm-4:30pm

    In this workshop we explore how large companies express their research and innovation plans. By looking at examples we identify the key components and how academics might express their work in these terms. We then look at the way you express your research programme and identify any differences.

    Understanding behaviour in problem structuring methods interventions with activity theory

    Thursday 29 October 2015, 1pm-2pm

    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. Activity theory is presented as a conceptual framework and methodological guide for researching and understanding OR interventions. A case study describing the use of this approach will be discussed.

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

    Wednesday 28 October 2015, 1pm-3pm

    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*). For ranking departments and institutions, the Multi-Attribute Value Theory (MAVT) has been extended to include profiles with random values of the ordered star scores. The extended MAVT methodology can be also used in other applications for which performance and weight profiles are available.

    MacBethSort: A Multiple Criteria Decision Method for Sorting Strategic Products

    Thursday 1 October 2015, 1pm-2pm

    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. Therefore, the number of products in a class is independent of the actual importance of the products. In this paper, a new sorting technique MacBethSort is introduced, which is an evolution of the ranking technique MacBeth.

    Exploring Decision Maker Preferences for Solving Stochastic Multiobjective Programming Problems

    Thursday, 4th June 2015, 13:00 - 14:00 (BST)

    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, 21st May 2015, 13:00 - 14:00 (BST)

    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, 20th May 2015, 09:30 - 15:00 (BST)

    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.

    Mathematical Models for the Territorial Re-organization of Public Services

    Thursday, 7th May 2015, 13:00 - 14:00 (BST)

    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

    29th March - 31st 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

    Friday, 13th March 2015, 08:30 - 10:30 (GMT)

    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.

    Split-Merge: Using Exponential Neighborhood Search for Scheduling a Batching Machine

    Thursday, 12th March 2015, 13:00 - 14:00 (BST)

    This study addresses the problem of scheduling a single batching machine to minimize the maximum lateness with a constraint restricting the batch size. A solution for this NP-hard problem is designed by a selection of jobs for each batch and an ordering of those batches.

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

    Thursday, 26th February 2015, 13:00 - 14:00 (BST)

    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, 19th February 2015, 13:00 - 14:00 (BST)

    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.

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

    Thursday, 29th January 2015, 13:00 - 14:00 (BST)

    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.

    Managing Cyber and Information Risks in Supply Chains: insights from an exploratory analysis

    Thursday 3 November 2016, 1:00pm - 2:00pm

    The increasing level of connectivity is transforming supply chains, creating new opportunities but also new risks in the cyber space. Hence, cyber supply chain risk management (CSCRM) is emerging as a new management construct. The purpose of this study is fourfold: to identify cyber and information risks and sources from a supply chain management perspective; to investigate how companies perceive those risks; to explore initiatives adopted to confront them; to investigate ways in which firms can develop CSCRM capabilities.
