Validation of an expert system for inventory replenishment using case studies

Abstract

The design of vertical formwork is dependent on the lateral pressure predicted to act on the form face; due to the pressure envelope it is difficult to establish a comparison between different methods using only statistical parameters. Therefore, this article has two main objectives, firstly intent to explain why ratios of measured pressure to calculated pressure (E/T) can be accepted to validate a model, and secondly intent to quantify the maximum ratio E/T that can be accepted in the validation.
