Abstract

This programme has to be planned within strict but fluctuating funding limits. Traditional investment selection and planning techniques have to date been employed with great difficulty. An innovative approach, called Portfolio Optimisation, is being implemented, which shows great potential for improving the business planning process. This paper describes the concepts underlying the approach and the supporting computerised modelling processes. Maximising investment benefits London Underground Limited (LUL) operates one of the largest metropolitan public railways in the world. Capital investment varies between £500 million and £700
