Q. 1 Defence Procurement & Supply Chain
Difficulty: Easy (1 Mark)
What is the 'Bullwhip Effect' in supply chain logistics management?
A
The phenomenon where small fluctuations in retail/end-user demand create progressively larger swings in demand inventory upstream at wholesale, distributor, and manufacturer levels
✓ Correct
B
A physical punishment used in military disciplinary barracks
C
A rapid acceleration of freight trains carrying heavy ammunition
D
The sudden drop in fuel prices during wartime
💡 Step-by-Step Explanation & Concept Rationale
The Bullwhip Effect stems from demand forecast updating, order batching, price fluctuations, and rationing gaming, leading to massive excess inventory and stockouts across the supply chain.
Q. 2 Defence Procurement & Supply Chain
Difficulty: Medium (1 Mark)
What is the 'Reorder Point' (ROP) formula under continuous inventory review systems?
A
ROP = (Average Daily Demand * Lead Time in Days) + Safety Stock
✓ Correct
B
ROP = Total Annual Budget / Number of Depot Employees
C
ROP = Warehouse Floor Area * Ceiling Height in Meters
D
ROP = Invoice Price * Total Depreciation Rate
💡 Step-by-Step Explanation & Concept Rationale
The Reorder Point triggers a replenishment order when on-hand stock drops below the level needed to cover anticipated demand throughout the delivery lead time plus safety buffer.
Q. 3 Defence Procurement & Supply Chain
Difficulty: Hard (1 Mark)
In military logistics and provisioning, what is the 'Two-Bin System' of inventory control?
A
A visual replenishment system where items are drawn from Bin 1; when Bin 1 is empty, a replenishment order is placed immediately while items in Bin 2 cover lead-time demand
✓ Correct
B
Separating combustible waste from non-combustible waste in barracks
C
Storing ammunition in two separate underground bunkers
D
Assigning two military police guards to every warehouse entrance
💡 Step-by-Step Explanation & Concept Rationale
The two-bin system is a simple, highly effective decentralized visual control mechanism widely utilized in military workshops and field depots for fast-moving hardware and fasteners.
Q. 4 Defence Procurement & Supply Chain
Difficulty: Easy (1 Mark)
What does 'Vendor-Managed Inventory' (VMI) establish between a procuring agency and a defence contractor?
A
The supplier assumes responsibility for monitoring inventory levels at the customer's warehouse and automatically initiates replenishment orders to maintain agreed stock levels
✓ Correct
B
The customer purchases the entire manufacturing plant of the vendor
C
The vendor manages the payroll of the military logistics officers
D
The customer delivers raw materials to the vendor's private residence
💡 Step-by-Step Explanation & Concept Rationale
VMI integrates digital inventory visibility (EDI/ERP), aligning replenishment schedules, reducing stockout risk, and eliminating the customer's daily purchase order administration burden.
Q. 5 Defence Procurement & Supply Chain
Difficulty: Medium (1 Mark)
In supply chain distribution network design, what is 'Cross-Docking'?
A
A logistics practice where inbound shipments from suppliers are unloaded and directly loaded onto outbound transport vehicles with zero or minimal intermediate warehouse storage
✓ Correct
B
Tying two naval ships together during rough sea replenishment
C
Building warehouse docks that cross over public railway lines
D
Inspecting shipping containers with dual X-ray scanners
💡 Step-by-Step Explanation & Concept Rationale
Cross-docking streamlines military hub-and-spoke distribution, eliminating pallet put-away and picking labor while slashing inventory holding times to hours rather than weeks.
Q. 6 Defence Procurement & Supply Chain
Difficulty: Hard (1 Mark)
What is 'FSN Analysis' in warehouse inventory management?
A
Classification based on inventory consumption velocity: Fast-moving (F), Slow-moving (S), and Non-moving / Dead stock (N)
✓ Correct
B
Classification based on Flash point, Solubility, and Neutrality of chemicals
C
Foreign, State, and National source labeling
D
Free, Standard, and Negotiable procurement terms
💡 Step-by-Step Explanation & Concept Rationale
FSN analysis assists warehouse managers in identifying dormant and obsolete military spare parts (Non-moving) for disposal, while optimizing bin locations for Fast-moving items.
Q. 7 Defence Procurement & Supply Chain
Difficulty: Easy (1 Mark)
What does 'Total Cost of Ownership' (TCO) evaluate in military equipment lifecycle procurement?
A
The comprehensive financial cost of an asset over its entire life: Initial Acquisition Cost + Operating & Fuel Costs + Maintenance / Spare Parts + Training + Decommissioning / Disposal Costs
✓ Correct
B
The initial invoice sticker price paid at the time of delivery only
C
The annual insurance premium paid on military vehicles
D
The cost of shipping an item from the port to the central depot
💡 Step-by-Step Explanation & Concept Rationale
In defence acquisitions, acquisition cost often represents only 20-30% of TCO; operating, maintenance, upgrade, and sustainment costs represent 70-80% of total lifecycle expenditure.
Q. 8 Defence Procurement & Supply Chain
Difficulty: Medium (1 Mark)
What is 'Line Balancing' in military depot repair production lines?
A
Assigning overhaul tasks to sequential workstations such that the processing times at each station are nearly equal, maximizing throughput and eliminating bottlenecks
✓ Correct
B
Calibrating the electrical voltage of overhead crane power lines
C
Painting straight white safety lines on workshop floors
D
Balancing the physical weight of transport aircraft cargo pallets
💡 Step-by-Step Explanation & Concept Rationale
Line balancing eliminates idle station time and prevents buffer accumulation, ensuring smooth continuous production flow through depot overhaul lines.
Q. 9 Defence Procurement & Supply Chain
Difficulty: Hard (1 Mark)
What is 'Safety Stock' designed to buffer against in volatile supply chains?
A
Demand uncertainty (unanticipated spikes in usage) and Lead-time variability (supplier or transport delays)
✓ Correct
B
Changes in local sales tax percentages
C
Routine depreciation of fixed assets
D
Annual changes in military uniform ranks
💡 Step-by-Step Explanation & Concept Rationale
Safety Stock provides a statistical buffer calculated as Z * sigma_L * sqrt(L), shielding military operational units from unpredictable supply line disruptions and combat consumption surges.
Q. 10 Defence Procurement & Supply Chain
Difficulty: Easy (1 Mark)
What does 'Inventory Turnover Ratio' (ITR) measure in logistics performance?
A
Cost of Goods Sold (or Annual Consumption Value) / Average Inventory Value; measures how many times inventory is sold/consumed and replaced over a year
✓ Correct
B
The physical speed at which forklift trucks rotate inside warehouse aisles
C
The number of times warehouse staff rotate work shifts
D
The percentage of damaged shipping boxes returned to suppliers
💡 Step-by-Step Explanation & Concept Rationale
A higher Inventory Turnover Ratio indicates efficient inventory management, high liquidity, and minimal capital tied up in dormant or stagnant warehouse stock.
