Expert System

Glossary

• Rule: Has Premises and Conclusion
• Premise: It is a hypothetical fact that can be true or false depending on the users responses or other conclusions.
• Conclusion: It is a hypothetical fact that can be true or false depending if the premises are met.
• Fact: It's a true event depending on the users's input ot triggered rules

Functionality

• This is an Expert System for Quoting Solar Panels
• Is Base on Rules
• Options
  • Also called Premises
  • The Premises are linked with the AND behavior in the rules
• Variable:
  • A Variable has multiples options
  • All variables have the empty option
  • Variables support scalar values, just set the is_scalar = True
  • If is_scalar is set to True and the given value is different from EMPTY, the value of the option will be replaced with the given value.
• Rule
  • If all the values match with the given ones the conclusions becomes facts
  • A rule could trigger multiple facts
  • If a given value contradicts a premise the rule is removed
  • A rule can be a formula
  • if a rule is a formula, it only conclude one variable
• The inference's steps are stored in a dictionary of lists, so It's possible to go backwards

Features

• If you want to emulate ruling out variables just set it to the empty option the variable so multiples rules will be removed

To Dos

• Make the final conclusion downloadable from an endpoint
• Store the selected devices in the database linked to a client
• put and order to orphan vars
• Group var trees which share some children
• Refactor code
• Create an endpoint to remove a cached inference
• Create a class group of deduction and a function that interprets them, since it starts to take a lot of code to do so
• Create and endpoint that shows an overview of a quotation
• make possible to store a scalar value in the option table
