Special Interest Group on Supply Chain Forecasting
The Lancaster Centre for Foreasting hosts a number of different research interests, past and current research grants, applied research projects with companies and PhD students in the area of Forecasting for Supply Chain Management.
Supply Chain Forecasting Research: Best Practices & Benchmarking study
Following on from the successful pilot study last year (see below), the research has been sharpened to focus on best practices and benchmarks for forecasting in a supply chain context. The online survey has been improved to facilitate data collection and we are seeking a far larger sample to add reliability to the findings.
To be more specific, the study investigates on the following research questions:
(a) What types of information are available to forecasters?
(b) How are forecasters using this information, if at all, in their forecasting process? Through statistical methods and/or judgement?
(c) How do forecasters cope with different data conditions and forecasting requirements of different customers?
The survey is comprehensive and measures current forecasting practice in a range of other dimensions including: level of granularity (time buckets, supply chain level), forecasting methods, software, mode of exchange, types of collaboration, demand characteristics.
We are still seeking additional participants with sound knowledge of forecasting in a single company or business unit to contribute their expertise to the study.
ONLINE SURVEY (www.supplychainforecasting.co.uk)
The response to date has been very positive and is already providing some new insights in Supply Chain Forecasting practice under S&OP, VMI and CPFR. The research will be of special interest to those with a current or planned involvement in collaboration & information-sharing with trading partners down the supply chain.
The study is not for commercial purposes and all responses will be treated in the strictest confidence (anonymous replies are possible).
For your part in helping to contribute to the study, you will receive a copy of the findings, with valuable insights into:
- Best practices in Supply Chain Forecasting (overall and by industry)
- Benchmarks in forecasting accuracy (overall and by industry)
The survey will take between 20-30 minutes depending on your forecasting setup and all responses will be treated in the strictest confidence. It is possible to pause and complete it at a later point. To start taking the survey visit: www.supplychainforecasting.co.uk.

Supply Chain Forecasting - Practitioner Round Table
The Forecasting round table, initiated and run mutually with Jonathan Aylen and Kevin Albertson through Manchester University, provides a free and open forum for pratitioners, demand planners, forecasting and supply chain managers from retail, manufacturing and suppliers of consumer packaged goods (both durable and non-durable). In addition, it facilitates an open exchange with software vendors and academics with an interrest in forecasting for supply chain management.
Successful first meeting of the Supply Chain Forecasting Round table
Thursday 14th October 2010, City University, London, UK
The Lancaster Centre for Forcasting is pleased to have run the first successful half-day event in a series workshops uniting practitioners, academics and vendores in Supply Chain forecasting, funded by and in collaboration with the British OR Society on
"Forecasting with Promotions - Current Practice and future prospects"
This afternoon event covered different aspects of the challenges in promotional forecasting & evaluation for supply chain management, which badly affects retailers and manufacturers alike. The two keynote presenters, Gareth Brentall (MD of Promax Europe Ltd) and Barry Grange (CEO of Retail Express), both with many years of practical experience in the area, described their own distinctive approaches to the challenges in promotional forecasting. The event kicked off with Prof. Robert Fildes, director of the Lancaster Centre for Forecasting, with an overview of current practices and research in promotional forecasting. The event offered ample opportunity to network amongst practitioners, vendors and academics, and included three keynote talks:
Current research in Forecasting Promotions - Judgment v Statistics?
Prof. Robert Fildes, Distinguished Professor, Lancaster Centre for Forecasting

Forecasting using Statistical Models Combined with Judgment
Supply chain planning is wholly reliant on accurate forecasts in most industries and these forecasts are provided through FSSs. Current evidence suggests that these systems are not used effectively so that large and costly errors are associated with the resulting forecasts. This is a continuing project examining all aspects of supply chain forecasting. Such forecasts are made using a base-line statistical method which is then adjusted by expert company forecasters to deliver a 'final' forecast. This final forecast is then used in all aspects of supply chain planning affecting service levels, cash flow, human resource scheduling etc.
Initially, the UK based Engineering and Physical Sciences Research Council (EPSRC) funded a research project in Forecasting Support Systems. The project, over three years, was supervised by Professor Robert Fildes (Lancaster University Management School) and Professor Paul Goodwin (School of Management, University of Bath) with Dr Konstantinos Nikolopoulos acting as Research Officer (Please visit Project web site). It had as its focus two issues:
- the inefficient use of managerial judgment when adjusting the statistical forecasts to take into account special events such as promotions.
- the design of forecasting support systems to improve judgments.
The research has continued through the appointment of doctoral researchers and a Marie Curie Fellow, Dr Juan Trapero Arenas. He examined non-linear effects when experts respond to information (please see his project report). The initial findings are published in the Journal of Forecasting.
Within the supply chain an important phenomenon undermining efficient supply chain performance is the bullwhip effect. This occurs when demand uncertainty at the retailer is amplified for the manufacturer. The phehomenon arises due to retailer ordering patterns and lead time delays. Juan, working with Dr Nikos Kourentzes and Professor Robert Fildes has examined how information sharing between retailer and manufacturer can help improve forecasting performance and overcome the adverse effects of the bullwhip, presented in a working paper..
Research students & topics in the Supply Chain forecasting group:
Dr. Stavros Asimakopoulos - Thesis: A human-computer interaction perspective on forecasting systems design
Andrey Davydenko - Thesis. Integration of judgmental and statistical approaches for demand forecasting: models and methods
Ioannis Stamatopoulos - Thesis: The impact of demand uncertainty on supply chain perfomance and the value of collaboration
Dr Juan Trapero Arenas - Marie Curie Fellowship: Supply Chain demand forecasting based on unobserved component models. His final report of his fellowship is in the attached document.
Matt Weller - Thesis. Forecasting models for supply chain collaboration. The research aims to investigate the information exchanged between retailers and manufacturers and how it is used in the forecasting process. Collaboration between partners (as well as internally through S&OP) is growing and with it comes a large volume of data which can be leveraged to drive forecast improvement.
