Examines the ways in which computers can be used to assist in management decision making, emphasizing, above all, the practical aspects. Begins with the provision of management information, and goes on to consider the scope for bringing the computer into the decision itself. Discusses traditional operations research methods, as well as simulation techniques which are noted as being similar in principle to spreadsheet‐based models for planning and financial projections. Also considers knowledge‐based methods which handle qualitative rather than quantitative factors.
