Search words, quoted phrases, and exact IDs across the current corpus.
By default, all meaningful words must match the same source passage, in its text or titles. Matching ignores letter case. Ordinary word queries skip common English function words such as the, and and or; quotes keep a phrase, and uppercase operators control matching.
| Example | What it does |
|---|---|
controlled variation | Requires both meaningful words; their order may differ. |
"controlled variation" | Requires adjacent words in that order. |
SYSE.24:4 | Prioritizes the exact named section. Pattern IDs also work. |
engineering OR management | Matches either alternative. Write OR and AND in uppercase. |
engineering AND (research OR management) | Requires engineering together with either grouped alternative. |
engineering -management | Excludes passages that match management. |
title:"controlled variation"body:"controlled variation" | Restricts the phrase to section/publication titles, or to source text. A field prefix applies to the following term or phrase. |
"controlled variation"~1 | Allows one intervening word in the phrase. |
"controlled vari"* | Requires adjacent words, with the last word as a prefix. |
engineering^2 OR management | Gives engineering matches more ranking weight. |
The Publication, Suite and Type filters narrow the same query. Results are source passages, not generated answers. Search does not translate, expand synonyms or automatically correct spelling. For a task expressed in another language, try English terms and read the context. Press / to focus the search field.
PSDA.9 - Test Robustness and Sensitivity of Decision Alternatives and Their Comparison Type: Method pattern body Status: Stable Primary working result: robust regions, reversals, and information priorities for one decision-support comparison: the conditions…

Use the illustrative F and M slice from PSDA.8: F costs 8 incremental budget units and loses 2 service hours with normal access or 3 with road loss; M costs 5 and loses 1 or 9 hours. N remains the baseline and S still has an unqualified whole-arrangement…

PSDA.9:4 - Solution Declare the claim and variation space, challenge it with the least costly tests that cover the live failure mechanisms, and return supported regions, reversals, and bounded information questions. Keep the actual later decision separate…

PSDA.9:10 - Rationale A decision-support result is strengthened by exposing its reversal conditions, not by defending one point estimate. Separating uncertainty, values, model structure, and response capability prevents robustness from becoming a general…

PSDA.9:9 - Consequences The recipient learns not only what currently compares favorably but where the conclusion can fail. A retained set or conditional recommendation can be more useful than a fragile winner. The cost is targeted recomparison and explicit…

PSDA.9:2 - Problem A one-point ranking can hide a narrow region of support. Small changes in a value trade-off can reverse it; a common-cause failure can defeat every alternative; a different model can change which conditions are even represented. Sensitivity…

PSDA.9:3 - Forces Force Tension Coverage and effort Joint or structural changes can matter, while unrestricted scenario expansion consumes the available time. Stability and truth Repeated agreement supports only the tested model and region, not the omitted…

PSDA.9:7 - Conformance Checklist The exact comparison, subject, configuration, horizon, and robustness claim are stated. The robustness criterion is explicit and not chosen after seeing the preferred winner. Variation ranges, scenarios, dependencies, and…

PSDA.9:12 - Relations PSDA.8 may supply the consequence comparison and its evidence for the same configuration and horizon. Evidence enables this test but does not establish its result. PSDA.14 may consume robust regions, reversals, and information priorities…

PSDA.9:5.3 - Cheap non-use and honest stop A current analysis already proves the same service comparison throughout the relevant parameter interval, and the only proposed new computation repeats interior points without challenging another assumption. Reuse…

PSDA.9:1 - Problem frame Use this when a favored alternative depends on a forecast, weight, model, or threshold that might change, or when a precise ranking hides plausible reversals. Also use it when the recipient asks whether further information would…

… reopens the result. PSDA.14 may use this evidence for the same configuration and horizon to compose a recommendation. Evidence does not entail that recommendation or the later receiving decision. An unavailable, stale, or incompatible robustness result can be…

Recover the exact alternatives, consequence comparison, value basis, subject, configuration, horizon, and receiving use. Use PSDA.8's comparison and evidence only where they match those conditions. A qualified direct comparison can supply the same input.…
