11. REFERENCE-COSTSIf the user wishes to consider the economic tradeoff between various alternativedesigns or determine the cost of changing design parameters, it isimperative that realistic cost data be assigned to PLANT-EQUIPMENT instructions.Because the size of equipment is often unknown at the start of analternative or parametric run (i.e., the user defines SIZE = -999 in thePLANT-EQUIPMENT instruction), the user cannot input actual costs, but must relyupon the defaults of PLANT-EQUIPMENT instruction and sub- sequent scalingrelationships between equipment size and cost (see PLANT-EQUIPMENT) to approximatethe actual costs. The standard defaults for the PLANT-EQUIPMENT instructionare not sufficient for these purposes because material and labor costs arecontinuously changing. The REFERENCE-COSTS instruction is used as a mechanismto adjust these default values so that reasonable costs can be determined.Assigning a value to any of the keywords of the REFERENCE-COSTS instructionautomatically replaces the appropriate standard default values of thePLANT-EQUIPMENT instruction. Such an assignment, however, will not supersedea PLANT-EQUIPMENT keyword explicitly defined by the user.REFERENCE-COSTSTYPESIZE-REFFIRST-COST-REFThis command word informs the PDL Processor that the data tofollow will redefine the default values for thePLANT-EQUIPMENT instructions.is a code-word selected from Table V.2 that identifies thePLANT-EQUIPMENT instructions whose default values are to bechanged.
