MGMT90141 Chap.3 Integer and Logical Business Decisions
Integer and Logical Business Decisions
Define binary variable
The course material gives this chapter a concrete anchor: Week 4 covers integer applications, while the assignment guidance permits LP or IP models for organisational problems.
That binary variable anchor controls how integer programming is explained and how logical constraint is tested in changed practice.
Integer and Logical Business Decisions frames a decision through binary variable, integer programming and logical constraint.
The objective is to model indivisible, setup and either-or decisions without accepting infeasible fractions, so the chapter should be read as a chain from problem definition to evidence, option comparison and accountable action.
Start with binary variable and name the decision owner, affected stakeholders and time horizon.
The same binary variable fact can matter differently across those positions, so the opening frame determines which evidence is relevant.
Use integer programming to explain how the present condition produces an opportunity, cost or risk.
A strong integer programming mechanism states what changes, for whom and through which organisational, market or institutional process.
Formula checkpoint
The big-M value must be justified tightly enough to encode the logic without damaging model behaviour.
Linear programming
In MGMT90141, Linear programming belongs with binary variable and integer programming because students use it to model indivisible, setup and either-or decisions without accepting infeasible fractions.
A defensible use of Linear programming should define the term, connect it to the case evidence and test the conclusion through logical constraint; repeating the phrase without that chain does not demonstrate understanding.
Trace integer programming
Apply logical constraint when comparing options. Keep the logical constraint criteria distinct, test trade-offs and ask which assumption drives the recommendation.
A score or matrix helps only when its criteria are justified by the case.
For the application — model indivisible, setup and either-or decisions without accepting infeasible fractions — finish with an actor, action, rationale and review trigger. This turns the logical constraint analysis into a recommendation while keeping the decision open to new evidence.
Build a decision ledger.
Separate the current condition, the stakeholder affected, the evidence supporting binary variable, the mechanism represented by integer programming and the criterion supplied by logical constraint.
If a logical constraint recommendation cannot point back to one of those entries, it is probably preference dressed as analysis rather than a consequence of the case.
Compare at least two feasible options against the same criteria. State who benefits under logical constraint, who bears cost or risk, what capability implementation requires and what evidence would reveal failure.
This comparison is essential when students need to model indivisible, setup and either-or decisions without accepting infeasible fractions, because an attractive option is not defensible until its trade-offs are visible.
Test with logical constraint
Rehearse the MGMT90141 binary variable response as a short briefing: one sentence for the decision, two for the evidence and mechanism, one for the alternative and one for the qualified recommendation.
Then expand only the integer programming move that needs more support. This protects the argument structure under a strict word or time limit.
A complete response should make the task visible before the detail: identify what must be decided, define the relevant terms, connect the evidence to integer programming, and use logical constraint to test the result.
The final sentence about logical constraint should answer the question actually asked rather than merely repeat the topic.
The controlling limit is specific: Integer restrictions can change both solution and sensitivity and should be imposed only when the real decision is indivisible.
Keep that logical constraint limit beside the worked example, because it separates a careful MGMT90141 answer from one that sounds confident but claims more than the task or evidence supports.
For revision, retrieve binary variable, integer programming and logical constraint without notes, explain their relationship aloud, then complete a changed version of the application: model indivisible, setup and either-or decisions without accepting infeasible fractions.
Record the first failed integer programming reasoning move and repair it before attempting another case.

Key terms
- binary variable
- A decision variable restricted to zero or one for modelling yes-or-no logical choices. Use this definition when the task is to model indivisible, setup and either-or decisions without accepting infeasible fractions.
- integer programming
- Optimisation in which selected decisions must take whole-number values rather than arbitrary fractions. Use this definition when the task is to model indivisible, setup and either-or decisions without accepting infeasible fractions.
- logical constraint
- A mathematical relationship encoding implication, mutual exclusion, setup or selection rules among decisions. Use this definition when the task is to model indivisible, setup and either-or decisions without accepting infeasible fractions.
Integer and Logical Business Decisions FAQ
What is the main task in Integer and Logical Business Decisions?
Model indivisible, setup and either-or decisions without accepting infeasible fractions.
How do binary variable and integer programming work together?
Use binary variable to establish the object or condition, then use integer programming to explain how it changes the outcome being analysed.
What must a MGMT90141 answer qualify here?
Integer restrictions can change both solution and sensitivity and should be imposed only when the real decision is indivisible.
How should I revise Integer and Logical Business Decisions?
Retrieve binary variable, integer programming and logical constraint, apply them to a changed case, and correct the first point where the evidence no longer supports the conclusion.
Exam move
Reconstruct the relationship among binary variable, integer programming and logical constraint; complete the chapter application without notes; then test the result against this limit: Integer restrictions can change both solution and sensitivity and should be imposed only when the real decision is indivisible.
