Talk Title: A Principled Basis for Decision: Enduring Operational Research (OR) subjects and principles for Quality Assured Analytics

Abstract: In a world of change, some things don't. This presentation proposes that efficiency, effectiveness, human interactions and behaviour remain perennial foci for much OR analytics and that quality analytics depend on perennial principles of assurance. Professor Pat Rivett's three subjects for his 1964 BBC documentary about Operational Research: Cutting the Queue, Playing It Through and The Human Factor, are examples of analysis of efficiency, effectiveness and behavioural OR. These remain major subjects for OR although the means to analyse them have evolved. Confidence in analysis is the other perennial aspect. The presentation describes the Department for Business Energy and Industrial Strategy (BEIS) approach to model assurance. Analytical tools for Big Data and Artificial Intelligence provide wider domains for OR. In that wider domain clarity of purpose and assurance of quality will remain essential enablers for a principled basis for decision.

PathSim – a versatile capacity model for simulating an admitted patient pathway; with application to the redesign of a stroke service

Venue: CCG Boardroom (Lower Ground Floor), NHS Bristol, Bristol BS1 3NX.
Speaker: Richard Wood - Bristol, North Somerset and South Gloucestershire CCGs
Date: Thursday, 01 February 2018 at 17:45

Tea and coffee will be available from 17.15 with the talk due to start at 17.45.

Abstract:
Stroke is one of the leading causes of death in the UK and puts a great strain on health services, especially the relationship between hospital and social care. Recent studies suggest that some health systems may benefit from a centralised hyper-acute stroke unit, providing a specialist 24 hours a day service and a singular point of access to downstream localised secondary and tertiary care. However, assessing the suitability of such a transformation for a particular locality, alongside the optimal configuration of bed capacity along such a pathway, is not a straightforward task. At the heart of this is the lack of a versatile stochastic modelling approach within the literature that is appropriate to this kind of problem; that offers control over output measures that could be useful to clinicians; and that is available without cost, making it readily useable in the NHS. In addressing these requirements we have created PathSim, a discrete event simulation based on a continuous-time Markov chain which models arrivals, length of stay and discharge routings between facilities along an admitted patient pathway. This is essentially a queuing network problem where the customer (patient) is held at the current facility until a service channel (bed) is available at the required downstream destination. This “bed blocking” can represent significant system inefficiency, and thus understanding the dynamics of these bottlenecks through a model can help the development of pathways which are cost-effective and improve the quality of service to patients.


OR applied in decision support for strategic maintenance planning in the offshore wind industry

Venue: Room 4D05, D Building, UWE Frenchay campus, Coldharbour Lane, Bristol BS16 1QY
Speaker: Xiaodong Li, University of the West of England
Date: Monday, 10 July 2017 at 17:00

Tea and coffee will be available from 17.00 with the talk due to start at 17.30.

The talk introduces a Decision Support System (DSS), which is developed for maintenance cost optimisation at an Offshore Wind Farm (OWF). The DSS is designed for use by multiple stakeholders in the OWF sector with the overall goal of informing maintenance strategy and reducing lifecycle maintenance costs at the OWF. Both deterministic and stochastic optimisation models underpin the DSS. The deterministic version is intended for use by stakeholders with access to accurate failure rate data; and the stochastic model is intended for use by stakeholders who have less certainty about failure rates. At present, the mathematical model of the DSS is extended by considering more uncertain parameters, such as wind speed and its correlation with failure frequency. A wind speed dependent failure rate is adapted into an extended model. Weibull distribution and Markov process are proposed to predict the weather parameters. The updated DSS will be able to provide more accurate outcome results and hence to give more efficient support for strategic maintenance planning in OWF. In basis of the same algorithm, a web-based DSS to estimate OWF maintenance cost is under construction.


Joint SWORDS/WORDS Event - Diversity and identity: challenges and opportunities for UK OR

Venue: Cardiff School of Mathematics
Speaker: Ruth Kaufman, President of the OR Society
TBC
Meeting Details
The next meeting is a joint one with SWORDS and is scheduled for Tuesday the 7th of February 2017. The meeting will be held at the School of Mathematics, Cardiff University.There will be cheese and wine available from 5.15pm in room M/1.04 on the first floor in the School of Mathematics. The talk will commence at 6.00pm in room E/0.15 (ground floor). Please note that times and rooms are different to normal.
Abstract 
People engaged in an activity like O.R., can be described on countless dimensions. For example, personal characteristics (the 'protected characteristics' of ethnicity, gender etc. that are part of formal diversity initiatives, but also values, preferences, personality), daily work activities, customer,  owner, career path,  whether they have ever heard of O.R.  Diversity can be a strength; but so can uniform identity. This talk reviews some significant dimensions of diversity and identity in UK OR, to consider what we might need to do to overcome the challenges of too much or too little diversity, and where we can exploit the enormous potential benefits of the glorious variety of ways of 'being an O.R. person'.

Abstract:
The logistical deployment of resources to provide relief to victims of disasters and the appropriate planning and management of these activities are critical to reduce the suffering caused. Humanitarian logistics represents one of the most important fields during preparedness and response in cases of disaster, seeking to provide relief, information and services to disaster victims. On top of the challenges posed by logistical activities, disaster management commonly attracts many actors working alongside each other and sharing resources to cope with the emergency. Handling the resources of these actors is a complex task due to the variety of actors and resources available. This is particularly important for developing countries, where disasters occur very often and resources are even scarcer. Despite this, there is little research considering multiple organisations, and none concerning the optimisation of the number of actors required to avoid shortages or convergence. 
The aim of this research is to develop a system for disaster preparedness based on a combination of multi-objective optimisation and geographical information systems to aid multi-organisational decision-making. A cartographic model is used to avoid the selection of floodable facilities, and a bi-objective optimisation model is used to determine the location of emergency facilities, stock prepositioning, resource allocation and relief distribution, along with the number of actors required to perform these activities.
The system was applied to a case study in Mexico involving several relief organisations. The formulation proposed showed the capacity to optimise the decisions and the number of organisations required for logistical activities.

Abstract

Amongst the global threats to health facing the advanced economies, obesity is rapidly becoming a prime focus. This is because, in large measure, it is a condition which is a precursor for a range of more serious diseases, including diabetes and hypertension. Interest in a particular condition often results in governments and public health bodies setting targets aimed at reducing the prevalence of that condition in the general population. However, it appears that public health targets are not set by any informed background analysis but rather by what seems reasonable and is tolerable in political terms. In the UK in 2008 the then government announced that it would be striving, by 2020, to bring the obesity metrics back to those prevailing in 2000. Based upon a population-level model addressing the development of overweight and obesity in children (2-15 years), we demonstrate that the achievement of this target (in children) is highly unlikely. The model, which combines knowledge from nutrition, physical activity and body metabolism, shows that a plausible target date would be 2026 at least. Acknowledgement of the delays involved in reversing obesity trends is vital in setting sensible targets in this domain of public health. In general, models have an important role to play in the formulation of achievable public health targets.
