Use of computers in planning and execution of infrastructure investment

摘要

Railtrack is the principal United Kingdom provider of access to rail infrastructure for passenger and freight train operating companies. The company was vested in April 1994 and privatised by flotation in May 1996. Expenditure on the British Rail infrastructure which passed to Railtrack in April 1994 had been cash-limited in the public sector, leading to accumulated investment requiremtns over and above the level needed to meet steady state conditions. This paper describes the computer applications used to assess the scale of, and subsequently manage and report upon, the resulting investment programme.
