High level factorial plan

Interaction Analysis Using a High Level Factorial Plan... 

High-level FFEs such as, for example 1/4 or 1/8 from complete factorial experiments (CFEs) can be used for complex processes, especially if the effect on the response of some factors is the objective of the research. It is not difficult to decide that, if we have a problem with the k factors where the p linear effects compensate the effects of interaction, then the 2 p FFE can be used without any restriction. The plan 2 p FFE keeps the advantages of the CFE 2 plan, then ... 

Forecasts are developed at a level of detail that is not actionable — This is a complementary point to the first one. That means the information is at too high a level, too broad in scope, or just plain not directly related to what must go into a master schedule. The result is a high-level forecast that gets modified so much it becomes meaningless for the needs of factory planning. 

Reference soil was collected in a reference site in Elorence (Italy). Real soil samples were collected in the Associated National Chemical Companies (ACNA) site (Cengio, SV, Italy). ACNA is a closed organic chemical industrial factory active since 1882 with the production of explosives (nitroglycerin, dynamite, and trinitrotoluene), paints, nitric and sulphuric acids, phenols, and amines, with serious levels of contamination of soil and surface waters, where a remediation and bonification plan started in 1999. The serious enviromnental contamination of this area determined its inclusion in the list of national priorities for enviromnental reclamation. The sampling was performed from the soil layers (0-30 cm) in a specific ACNA site, called hill n°5, on March 2003. The hill was made of waste from the industry accumulated during the years and was divided into four zones zone 1 with low contamination level zone 2 with pseudoreference zone 3 with moderate pollution level, and zone 4 with high ecological risk.
