pypetb's Introduction

THE PROCESS ENGINEER TOOLBOX

Process Engineer Tool Box is a package where a set of tools are developed to help in our daily tasks. It is based in the use of pandas. In daily chemical industry task, focused on data analysis and improvement projects developing, no long dataset are usually used and pandas cover all the requirements.

2- INSTALLATION

Use the package manager pip to install pyPETB.

pip install pypetb

pypetb's Issues

improve memory usage with slot

Create documentation

create RnRAtribute class

Allow title to be added to RnR_Report

I think it would be great if it were possible to, optionally, provide a title to the RnR_Report function. This to be able to show what measurement the graph is describing. I can put up a pull request if you think it is a good idea.

Create Capability Class test

Repeatability class

check if it must pass .t or .p

RnR_Report() root cause definition

When asigning root cause to operator it requires an space in the last sentence

add test automation wiht pre-commit

Read The Docs issue

link to Resolve #23 an update of the nottebook will be required

Remove dict_info from RnRNumeric()

dict_info is not used after removing report head part

number of distinct categories (NDC)

Include number of distinct categories (NDC) in the solve function, shows it in the log and in the report

improve RnRNumeric init input control

    self.dict_key=mydict_key    
    # Check dictionary is correctly defined
    lst_key=['1','2','3','4']
    if not all(key in mydict_key for key in lst_key):
      raise ValueError(
          f"Error init_01: wrong dictionary keys: {mydict_key.keys()} |"
          f" Be sure to use: {lst_key}"          
      )

create capability class

include as new feature

Import tables as tbl fail on GitHub workflow testing

Testing files after launching a pull merge fails due to tables module IS not found. Tables IS part of the package IS being developed and It IS calles by rnr module

RnRNumeric Class don't order measurement

it makes an unlegible trend in the RnR_Report() when data ar not sorted

improve RnRNumeric workflow

include RnR_Solve in init in order to reduce user steps

initializate project estructure

Create Capability class documentation

RnR_Numeric Docstring review

modify return docstring for chart generation in rnr_numeric

improve capability text boxes

increase boxes tittle location to avoid bad position when is running in databricks

Crossed, Nested, and Crossed & Nested structures; Additional sampling tree levels

Hello and nice work.

From looking at the code I believe the 'classical' gage R&R is implemented, where each operator measures the same set of parts, so measurement is nested under part, and part and operator are crossed.

Do you have any plans to support a fully nested sampling plan where each operator measures their own set of parts (mentioned in the article you referenced as a case in destructive testing)?

Additionally, it would be great to be able to analyze the variance components for a larger sampling plan. A simple example: each operator uses two gages, so parts are crossed with gages, and gages are crossed with operators.

improve text format

add new badge for python 3.8/3.9/3.10/3.11

Include RnR chart into RnRNumeric.RnRReport()

Remove info part of the report

Update docs notebook

Update rnr_report() before upload release v0.2.0

Increase compatibility

Source code was developed with Python 3.8. use It in poetry in order to increase the compatibility

Static colors and markers for technicians

As of right now the line colors and markers are randomized for each of the graphs. I think it would be better if they were static, so that each technician has their own color and marker across all graphs and multiple measurements. If you agree I can put up a pull-request :)

Convert Tables module to class one

color improvement in chart advisement

change green to mediumseagreen

publish to pyPi

Improve readthe docs

Check the documents of:

Docs update

Add an example adding tittle to the RnR_report() figure

add some badges

Unused space in generated image

Hi!

When saving the matplotlib figure as an image, I realized that the space wasn't utilized that well, lots of empty space in the generated image. I have made some adjustments to the gridspec in the figure and optimized the used space a bit better. Attached are some images of the old and new layouts. What do you think?
