In response to future energy shortages and resource scarcity, various countries are seeking alternative energy sources to avoid the situation of no resource availability. Gasoline Alternative Energy - Bioalcohol It has been widely used.
Bioalcohol belongs to biofuel (Biofuel) A type of biomass that is converted biologically or chemically into biomass (biomass) The raw materials obtained , it can extend the service life of parts and effectively improve the anti-knock index of gasoline. If mixed with gasoline in a low enough concentration, it can be used directly. At present, ethanol is already mixed with gasoline as automobile fuel, and has been used in car models launched by some automobile companies.
Let’s talk about JMP today use SPC Control to identify abnormal factors and compare performance before and after improvement . The figure below shows the flow chart for manufacturing ethanol. An example is as follows. An ethanol production plant currently finds that its output is unstable and there are problems with its process capabilities. It wants to know at what stage the problem occurred.
fermentation process
First, brainstorm among various departments and use fishbone diagram to find out the relevant factors, specify the parent and mother items, and find out the possible factors according to the classification of human-machine-material method loop. The following is a schematic diagram ( Non-fermentation process ) , JMP It also provides the ability to save the edited fishbone diagram to the data table, eliminating the need for re-editing.

Through comparison of control charts, it was found that the temperature control during the cleaning process was unstable. Through variability graph analysis, the factors that may have an impact are put into
variability plot
graph generator
It can be seen from the graph that there are differences among various operators. By performing variation test analysis and ANOVA Analyze to determine whether there are differences in the operations of online workers .
Variation test analysis and mean comparison
According to the results of the analysis, there are obvious differences among production line personnel, and personnel need to be re-educated, through subsequent data collection and comparison, and the use of SPC Control charts to observe the results before and after training .
By comparing the performance of personnel before and after training, it is obvious that the process has become stable. Although there is still room for improvement, further analysis can be conducted on abnormal points that exceed the control limits.
We can find that when JMP performs anomaly analysis, related tools and analysis methods can quickly help engineers find anomalies. These analyzes do not require complex techniques and difficult theories to perform. In actual applications, there will be more and more parameters. Complex, but the execution process is the same. Through the application of quality tools, we understand the process and improve it to further produce products that meet customer requirements. JMP is an essential tool to achieve this goal. you can also download Try JMP with a free 30-day trial.
