Applications accepted all year round

Applications are invited for a self-funded, 3 year full-time or 6 year part-time PhD project, to commence in October 2020 or February 2021.

The PhD will be based in the Faculty of Business and Law and will be supervised by: Dr Huijing Chen, Dr Maria Barbati and Professor Salvatore Greco.

The Faculty of Business and Law offers funding to attend conferences (currently £550), training (currently £450), and a work-based placement (currently a maximum of £3,000 tied up to the period of 12 weeks).

The work on this project will:

  • Understand models and methods for short-term demand forecasting and the literature on judgmental forecasting;
  • Examine the use of multi-criteria decision making (MCDM) techniques to enrich forecasting methods;
  • Develop a user friendly MCDM scheme to categorise demand for perishable products;
  • Design a training regime for planners in case organisation;
  • Measure ongoing improvement in forecasting practice and culture.

Demand forecasting is a task faced by many organisations. Typically large amount of forecasts are prepared at Stock-Keeping Unit level for production, replenishment and stock purposes. There are many demand classification schemes, often devised with the aid of MCDM techniques, in order to find the best forecasting methods and inventory policies for different classes [3]. Many of these classifications are developed specifically for spare parts and intermittent demand [2]. This project, however, focuses on fast-moving and perishable products. No such scheme exists, where the requirements can be very different from spare parts and accurate and timely forecasting is all the more important to reduce waste and ensure sustainability.

Modelling and computational advances over the years have seen fast development and availability of model-based forecasting methods. This project will develop a demand classification specifically suited for perishable products and identify appropriate forecasting methods. A portfolio of these methods can be suggested to the company, according to a variety of objectives to be taken into account and that can be explicated thanks to the interaction with the planners [1].

Using a real organisation as a case study, the multi-criteria classification scheme will be tested and benchmarked against the company’s current forecasting practice, which is mainly judgmental, prepared by planners with little or no statistical background. This project will also investigate how training can improve forecasting performance by (1) aiding understanding and acceptance of model-based forecasting, (2) guiding towards value-added judgmental adjustment where necessary and (3) fostering a continuous improvement culture.

The main research objectives of this project are:

  1. Develop a MCDM scheme based on demand classification and identify appropriate forecasting methods for the scheme;
  2. Empirically test and measure the performance of such a scheme;
  3. Design effective training for planning personnel to adopt the scheme and improve judgmental decision making;
  4. Measure ongoing improvement in forecasting practice and organizational benefits in sustainability.
