Programme Detail

The Art and Science of Modelling (Paul Fishwick, UT Dallas)

One of the characteristics of being human is to model. In our history, we began with representations of animals made from natural materials, and painted on cave walls. We also made regular marks on animal bones. While the modern accounting of these products is art (animal representations) and mathematics (bone marks), a more comprehensive understanding points to modelling in both cases. We saw or imagined things, and then we made models of our experience. This talk will be a non-technical, cross-disciplinary, introduction to modelling. I will discuss (1) the history of modelling, (2) a way of thinking about modelling using three broad categories, (3) the notion that computer and information science is a form of modelling, and (4) approaches to modelling across disciplines – from art and humanities to business, science, and engineering.

BIOGRAPHY: Paul Fishwick is Distinguished University Chair of Arts and Technology (ATEC), and Professor of Computer Science. He has six years of industry experience as a systems analyst working at Newport News Shipbuilding and at NASA Langley Research Center in Virginia. He was on the faculty at the University of Florida from 1986 to 2012, and was Director of the Digital Arts and Sciences Programs. His PhD was in Computer and Information Science from the University of Pennsylvania. Fishwick is active in modelling and simulation, as well as in the bridge areas spanning art, science, and engineering. He pioneered the area of aesthetic computing, resulting in an MIT Press edited volume in 2006. He is a Fellow of the Society for Computer Simulation, served as General Chair of the Winter Simulation Conference (WSC), was a WSC Titan Speaker in 2009, and has delivered over 24 keynote addresses at international conferences. He was Chair of the Association for Computing Machinery (ACM) Special Interest Group in Simulation (SIGSIM) four years from 2012 to 2016. Fishwick has over 230 technical publications and has served on all major archival journal editorial boards related to simulation, including ACM Transactions on Modeling and Simulation (TOMACS) where he was a founding area editor of modelling methodology in 1990. He is CEO of Metaphorz, LLC which assists the State of Florida in its catastrophe modelling software engineering auditing process for risk-based simulation for hurricanes and floods.

 

Enhancing Visitor Experience at Cultural Heritage Sites: Hybrid Systems Approach Incorporating Gaze-time Data with Computer Simulation (Andi Smart, Exeter)

The VISTA AR project (Interreg FCE programme) focuses on the use of digital technologies to enhance the visitor experience and to develop innovative business models for cultural heritage sites. This talk focuses on the development of a hybrid systems model using visitor intelligence (VI), gaze-time and computer simulation. VI tools are focused on understanding the visitor journey and experience. The visitor journey analysis includes assessing dwell-time and gaze-time.

A pilot study was undertaken in Exeter cathedral to capture the customer journey and included the use of eye-tracking technology to capture gaze-time of particular artefacts. The analysis of gaze duration was undertaken using heat-maps, which were indicative of the visitors' attention and interest. A particular challenge is communicating these results to management. A simulation model was developed to allow the presentation of the visitor journey. This allows management to observe the pattern of visitor journeys and the interest in different artefacts. The simulation model conforms to a ‘hybrid’ approach in that the data exported from the vision analysis software (Tobii Pro) directly informs duration activity (dwell-time and gaze-time). The sequence within the model is also derived from the vision data. A Discrete Event Simulation (DES) model, superimposed on a map of the building, was constructed using this data.

 

Modelling patient flows: Developing BPMN for fit-for-purpose operational flow mapping (Nathan Proudlove, Manchester)

Process mapping is a central tool in the understanding, improvement and design of processes. Different approaches have developed within different disciplines, in particular Value Stream Mapping in operations management, Business Process Model and Notation (BPMN) in enterprise information systems, and activity cycle/process flow diagrams for discrete-event simulation (DES) in operational research. Mapping patient pathways is a key tool in healthcare quality improvement, sometimes as a precursor to DES modelling. However, there is little formal guidance or widely-used approach. This work arises from projects involving process mapping in several hospitals. We find that BPMN tools are potentially very useful and provide nascent automated links to DES modelling for process improvement, but the treatment of important issues in flow (in particular queues/buffers/waste) is naïve and restrictive. We propose that some extensions to the BPMN object set to bring in operations management thinking and accommodate flow structures as found in, for example, hospitals, would produce a powerful, fit-for-purpose process mapping toolkit.

 

Enabling Real-time Simulation using Symbiotic Simulation, NHSquicker and Demand Forecasting (Navonil Mustafee (Exeter) and Stephan Onggo (Trinity College Dublin)

Symbiotic simulation is one of Industry 4.0 technologies that enables a close relationship between a physical system and the simulation model that represents it as its digital twin. Symbiotic simulation is designed to support decision making at the operational levels by making use of real- or near real- time data which are only available after the simulation model has been developed. From the modelling perspective, a symbiotic simulation system comprises a hybrid model that combines simulation, optimization and machine learning models as well as a data acquisition module and an actuator. The actuator is needed when the symbiotic simulation system is designed to directly control the physical system without any human intervention. This talk reviews the components of a symbiotic simulation system from the perspective of hybrid modelling. Examples within health care will be presented including NHSQuicker, demand forecasting for urgent care, and hospital bed management.

The next NWORG Meeting is in Manchester on Wednesday 18th April 2018. Full details are given in the link below.

The event focuses on policy in HMRC and the role of OR in analysing and evaluating policy measures. 

Book Your Place Now at the link below:-

https://www.eventbrite.co.uk/e/policy-matters-in-hmrc-challenges-for-or-north-west-operational-research-group-nworg-tickets-44788426389

Our speakers all have experience of dealing with policy evaluation in HMRC applying OR. Look forward to welcoming you.

Speaker profiles:-

Claire Breeze (FORS), KAI Direct Business Taxes Team, HMRC.

Member of Government Operational Research Service (GORS) for 11 years. Leads a time of operational researchers and statisticians delivering tax policy analysis for partnerships and companies.
 
In 2013 the Coalition Government announced two measures to counter commonly used structures involving partnership that gave rise to a tax advantage for the individuals involved. The two measures were expected to raise £0.6 billion year. The original estimates were known to be highly uncertain, OBR commissioned HMRC to evaluate the impact. The challenge for OR was to structure an evaluation methodology, review assumptions made in 2013 and work with tax policy colleagues and OBR to provide a robust evaluation.
 
 

Rosa Romita, KAI Direct Business Taxes Team, HMRC.

Member of Government Operational Research Service (GORS) since June 2017, previously worked in NHS Digital and as physicist for CERN.
Works on Large Businesses, both delivering tax policy analysis and understanding taxpayer behaviour.  
 
“Large Businesses” refers to the over 2,000 largest businesses that pay a significant proportion of the total business taxes and duties collected by HMRC. The Large Business database gives Senior Civil Servants a clear cross tax picture and helps them make informed decisions on compliance and policies. Large Businesses data is held in different databases, accessed by different people, with different identifiers for the Large Businesses and their entities. To build the Large Business database, the relevant information, such as tax receipts, ultimate country of ownership and risk scoring, is selected from different data sources. All data sources are then joined together through a ‘spine’, which makes adding additional data sources straightforward. The final tool is an Excel spreadsheet, with tables and charts built to easily get insight of data. I will present how the database is designed and built, together with examples of its uses in both monitoring compliance and informing policies.

 

David McDonald, KAI Personal Taxes Team, HMRC.

Member of Government Operational Research Service since January 2017. Works on National Insurance Contributions policy analysis.
 
HMRC make use of sector information, Standard Industry Classifications (SIC), as part of our analysis. One challenge we face is the miss-classification of companies, which affects the robustness of our analysis. To overcome this I am using Web Scraping, Natural Language Processing and Supervised Machine Learning to assign SIC codes to companies using only the company name. In this presentation I will outline these techniques and provide an overview of our initial results.
 
See you in Manchester on Wednesday 18th April 2018 at 14.50
You will find details of the venue and a map on the booking link.

Green Logistics: Decision Analytics for Sustainable Transportation
Professor Richard Eglese

Abstract:

The environmental effects of transporting goods are of increasing concern to managers and policy makers. The use of fossil fuels, such as petrol and diesel oil, in transport produces air pollutants that can have a toxic effect on people and the environment. However, one of the main drivers for the concern over the environmental effects of freight transport has been the potential effects of the production of greenhouse gas (GHG) emissions on climate change from the use of carbon-based fuels.

Research into models for transportation and logistics has been active for many years. Much of the modelling has been with the aim of optimising economic objectives or improving measures of customer service. However, in recent years, more research has been undertaken where environmental objectives have also been considered, so that supply chain and other logistic services can be delivered in a more sustainable way.

For the OR analyst, there are many choices to be made about how to model freight transport operations. Can old models be revised with a simple change of objective or are more radical changes needed? We shall examine some of these choices and illustrate the issues with cases studies to show what contribution can be made to environmental and other objectives through the use of decision analytic models. This will include issues raised by the use of new technologies, such as the use of electric or other alternatively powered vehicles.

Professor Richard Eglese

Richard Eglese is a Professor Emeritus in the Department of Management Science at Lancaster University Management School.
