Graphical analysis for machine replacement-A case study

Describes the advantages of combining a Windows^TM database package and a Visual Basic ^TM program for graphical analysis of machine replacement problems. The database allows the regular and easy updating of the cost elements associated with the purchase, operation and disposal of a machine. The Visual Basic^TM program provides a simple user interface, requiring only the use of a ‘mouse’ for input, program control, and graphical analysis of output. The program has easy access to appropriate database, spreadsheet and word-processing packages. Illustrates the use of the program in considering the graphical analysis of the replacement of an ambulance fleet.
