NIST HB135e2025, chapters 4, 7 and 8, supplies common-period costing, comparison of alternatives and programmes, and sensitivity reasoning. Those operations support the explicit consequence comparison; its federal rates and programme rules are outside this use.

FIN.9 develops whole incremental cash under interactions, dated constraints and service continuations. Its B+C example shows that a negative joint cash effect can reverse the allocation even when the combined initial funding remains feasible. Use that financial construction together with the actual engineering and operating conditions; financial interaction and physical feasibility answer different questions.

Enumeration fits a small indivisible shortlist because every permissible combination and exclusion can be inspected. Independent ranking is defensible only when the relevant choices and consequences are independent and the allocation rule fits the constraints. FIN.9’s value-per-capital ranking requires divisible, linearly scalable investments and one initial capital limit; indivisibility, minimum scale, interactions or later funding needs can defeat it. These conditions do not hold merely because each asset has a score.

An optimizer can help when enumerating a larger set becomes burdensome, provided the actual selection rules, interactions, dates and criteria can be represented. If a consequential relation remains unqualified, retain that uncertainty or obtain the missing result. Solver precision supplies no missing alternative or engineering support. A tutorial for a particular solver is unnecessary when the finite comparison already answers the asset question.
