• Role Conflict in Organizations:
• Role Conflict occurs when an individual simultaneously occupies multiple roles (or receives contradictory expectations within a role) whose divergent demands clash, such that fulfilling the requirements of one role makes fulfilling another role difficult or impossible.
• Distractors:
• Role Expectations: What others believe an individual should do in a given situation.
• Groupthink: A cognitive phenomenon where the desire for conformity within a cohesive group leads to irrational or uncritical decision-making.
• Group Size: The numerical count of members comprising a work team.

Correct option: (2) Role conflict

• Vogel's Approximation Method (VAM) in Profit Maximization:
• In a standard transportation problem (cost minimization), VAM calculates penalty costs by taking the difference between the two lowest unit costs in each row and column.
• In a profit maximization transportation problem, the penalty represents the opportunity loss of not selecting the most profitable cell. Therefore, row and column penalties are determined by finding the difference between the two highest unit profits (costs) in each row and column, ensuring allocations prioritize cells with maximal economic returns.

Correct option: (4) Finding the difference between the two highest unit costs in each row and column

• Queueing Theory: Causes of Waiting Lines:
• In operations research and queueing theory, waiting lines (queues) form fundamentally due to stochastic variability in arrivals and service times:
• Customer arrival patterns follow probabilistic distributions (e.g., Poisson arrivals with mean rate $\lambda$).
• Service duration per customer varies randomly (e.g., Exponential service times with mean rate $\mu$).
• Even when average service capacity exceeds average arrival rate ($\mu \gt \lambda$), random clustering of arrivals and temporary service delays create inevitable temporary queue bottlenecks.

Correct option: (3) Arrival and Service Variability

• Simulation in Operations Research:
• Simulation is an operations research and systems modeling technique used to imitate the operational behavior of a real-world system or process over time prior to actual physical performance.
• By building a mathematical or computer model (e.g., Monte Carlo simulation), managers can test various 'what-if' scenarios, evaluate system performance under uncertainty, and optimize layouts without incurring the substantial costs or risks of physical implementation.
• Distractors: Game theory analyzes strategic interactions between rational opponents; inventory control models optimize replenishment quantities.

Correct option: (1) Simulation
