  3. Main Functional Requirements - User

  4. Components Management Main Functional Requirements - Management • User Management • Login • Components Constraints Management • Decision Tree Management

  5. Non-Functional Requirements

  6. Main Classes TreeNode FinalProduct TreeNode CharacteristicValues BaseComponent QualityMeasure CPU PSU Memory

  7. Usage Scenario • A person who likes to buy a computer enters the website • The user answers questions about his needs • The answers and other user data is processed by the PCB Engine • The PCB Engine returns the suggested configurations to the view

  8. State Machine Register Insert Characteristic Info Login Answer Decision Tree Questions Build Product Logout Feedback

  9. PCB Question Tree While(hasQuestions){ Answers.Add(getUserAnswer()); if(a == null) break; //user pressed “done” Question newQuestion = getNextQuestion(a); showQuestion(newQuestion); }

  10. PCB Engine Input • The algorithm will get as input the user answers and a sorted list of components. • The list of components will be sorted by their relevance to the user’s answers.

  11. PCB Engine (Algorithm) While(totalMoney<budget){ f1.addComponent(sortedComponents, budget); } f2 = replaceLessSeg(sortedComponents, budget); undo(f1); While(moreCompToReplace){ moreCompToReplace = replaceNextComponent(f1); } finalProduct = compare(f1, f2);

  12. User Interface User Interface The PCB Expert website

  13. Task List

  14. Q&A Any Questions?
