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.
