Decision analysis and MIS terminology: What is the correct term for limits or restrictions imposed by the firm or its external environment on a decision maker (for example, capacity limits, budgets, or regulations)?

Introduction / Context:
In decision models and Management Information Systems (MIS), we separate controllable choices from non-negotiable boundaries. These boundaries—such as budgets, machine capacities, regulatory requirements, and deadlines—shape what solutions are feasible. Using the correct term matters for formulating linear programs, dashboards, and what-if analyses.

Given Data / Assumptions:

• The focus is on limits that restrict choices (not just descriptive inputs).
• Examples include capacity ceilings, minimum service levels, or policy rules.
• We seek the standard modeling term used across OR/MS and analytics.

Concept / Approach:
Constraints are mathematical or policy restrictions that candidate solutions must satisfy. In linear programming, they appear as equalities or inequalities; in policy contexts, they are business rules enforced by the system. By contrast, parameters are numerical inputs to a model (e.g., demand, cost coefficients), and constructs are conceptual variables in research design, not operational limits. “Perimeters” are physical boundaries, not modeling restrictions.

Step-by-Step Solution:

Verification / Alternative check:
Any optimization model shows decision variables bounded by constraints; removing a constraint enlarges the feasible region, confirming the role.

Why Other Options Are Wrong:

• Parameters: Inputs to a model, not restrictions.
• Constructs: Research/measurement concepts, not operational limits.
• Perimeters: Physical boundary lines, not decision rules.
• None: Incorrect because “constraints” is standard.

Common Pitfalls:
Confusing parameters with constraints; failing to encode a business rule as a formal constraint, leading to infeasible recommendations later.

Final Answer:
constraints
