Consecutive experiments plan

The present guide contains a description of a large number of synthesis experiments requiring quite complicated equipment. Before beginning such an experiment, the student must think it out thoroughly as a whole, compile a concise plan of the operations to be performed consecutively, and understand the purpose of each component of the apparatus. All the pieces of equipment in which experiments are run must be assembled compactly, suitably, and attractively. 

Sequence of experiment can be divided into two main types. In the first type, one of the boundary values of the independent variable is set, and then consecutive transfer from one experimental point to another takes place until the second boundary value will be achieved. A plan of such experiment is called a consecutive plan. 

The consecutive plan is widely used in many sensor experiments, especially in tests where the sequence of experiment itself is a peculiar parameter. Examples can be the sensor tests, where the sensor function is accompanied by hysteresis. 

The first restriction results in the consecutive plan of experiments, and the second one in resolution of the multifactor experiment on some sequence of single-factor and/or two-factor experiments. 

Five months after applying the survey, a process shift is indicated by seven consecutive points below the mean. The mean at the time of the survey was about 3.0, and after the shift, 2.2. This represents a reduction of over 25 percent. In our experience, this is a relatively small reduction. Figure 9.6 represents a single site of a smaller company that applied the survey and developed and implemented an action plan.
