A Methodology for the Development of Price Adjustment Systems for Statistically Based Restricted Performance Specifications.

摘要

This report presents a methodology which can be used to develop price adjustment systems suited for statistically based,restricted performance specifications. An example of the use of this methodology for a specific situation,that of bituminous concrete paving for the Pennsylvania Department of Transportation,is also presented. Three approaches are proposed for the development of a price adjustment system. These are: (1) the performance or serviceability approach, (2) the cost of production approach,and (3) the trial and error O.C. curve approach. A fourth approach,the cost of quality control approach,is also examined,but cannot be fully developed at this time because of the limited cost data which are available.
