Jitze van der Meulen, 20 Sept. 2005

Feedback mechanism

Data generat

or

Data use

1. Data control and validation versus reference

2. Evaluation versus requirements

3. Improvements versus technology

1. automatically? part of control, automatic pre-validation & control

2. Manually by the operator *3. R&D project

choice

1 data & warning, rather automatically, the easy way

e.g. on-line via desktop

2 data & application, manually, help yourselfe.g. by XLS macro

Presentaion of errors & bias

1. Gross errors & bias like in GDPS2. Distribution & standard deviation
