Professor Liu leads the LTA-RIG, whose members conduct research in a diverse set of areas within logistics and transportation

Logistics and Transportation Analytics Research Interest Group (LTA-RIG)

Leader: Dr Jiyin Liu, Professor of Operations Management

The Logistics and Transportation Analytics research interest group focuses on research, development and application of multi-disciplinary work that impacts on future challenges facing logistics and transportation. The members of the LTA-RIG utilise both qualitative tools (for problem exploration) and analytical tools (for problem solving). The group members are experienced in optimisation, modelling, heuristics, forecasting, systems thinking and case study work.

The group works with various stakeholders including academics, industrialists, businesses and policy makers on research focussed on supply chains risks management, sustainable supply chains, berth allocation and related decisions in shipping and terminal operations, logistics operations scheduling in the steel industry, business forecasting and situational awareness.

Research Focus:

Sustainable supply chains, berth allocation and related decisions in shipping and terminal operations, logistics operations scheduling in steel industry, distribution centre / warehouse operations, business forecasting, situational awareness, green logistics and dynamic pricing.

Associate members:

  • Samir Dani – Professor, Huddersfield University

Title:  "Exploiting OR techniques to transforming field operations"
Speaker:  Dr Gilbert Owusu, British Telecom
Date: Thursday, 12th June 2014

Abstract:
Demand forecasting and resource planning are critical steps in any organization’s bid to deliver high levels of customer service. A common misconception is that forecasts are inaccurate because the statistical method, or the general methodology, is inappropriate or being applied incorrectly. There are improvements in forecast accuracy when the right approaches/models are applied to the data at hand. However data is often highly reflective of the organisational context, i.e. the scope of demand forecasting may have several dimensions. The entire organisational context may include regions, domains, products, large customers, time and so on, and the product requirements may have several types. Forecasting in all these dimensions will end up in multiples of combinations of data. The limitations of data have led to the use judgmental methods and quantitative models. Gilbert will describe the process and technologies of managing demand and resources in transforming field force operations in BT.

Speaker Bio:
Dr Gilbert Owusu heads the resource management technologies research at BT and is Visiting Professor at the University of Essex. The technologies developed by Gilbert and his team have underpinned major transformation programmes and led to improved customer experience, cost savings and increased resource productivity in BT. His current research focuses on developing technologies that provide a coherent approach to optimising - (i) resource utilisation; and (ii) an organisation's service production lines with external partners.
