Take the rating and wait time from the most similar case; adjust wait time upward because cheaper places are often busier.

| Phase | Description | Example (Tech Support) | |-------|-------------|------------------------| | | Find the most similar past case(s) from the case library. | “Laptop won’t boot after Windows update.” → Retrieve similar cases with same error. | | 2. REUSE | Take the solution from the retrieved case and adapt it to fit the new problem. | Retrieved case: “Reinstall audio driver.” → Reuse but adapt: check display driver first. | | 3. REVISE | Test the proposed solution on the real world. If it fails, repair it or note the failure. | Solution fails → Try a different fix (system restore). | | 4. RETAIN | Store the new problem and its final (successful) solution as a new case in the library. | Add new case: “Laptop boot failure after update → fixed by system restore.” | Take the rating and wait time from the

1. What is CBR? Case-Based Reasoning (CBR) is a problem-solving paradigm that solves new problems by adapting previously successful solutions to similar problems. Instead of relying solely on general rules (like rule-based systems) or deep domain models, a CBR system keeps a library of past cases . repair it or note the failure.
