Q3
(a) State the different forms of waste management. 15 marks (b) State the various factors affecting plant location. 15 marks (c) An automobile company has additional capacity that can be used to manufacture brakes that the company is presently buying for ₹ 500 each. If the company makes the brakes, it will incur materials cost of ₹ 100 per unit, labour cost of ₹ 130 per unit and variable overhead cost of ₹ 30 per unit. The annual fixed cost associated with the unused capacity is ₹ 2,50,000. Demand over the next year is estimated to be 5000 units of brakes. (i) Would it be profitable for the company to manufacture the brakes ? (ii) Suppose the capacity could be used by another department for production of some agricultural equipment that would cover its fixed and variable cost and contribute ₹ 1,00,000 to profit. Which would be more advantageous, brakes production or agricultural equipment production ? 12+8=20 marks

(ii) मान लीजिए क्षमता अन्य विभाग द्वारा कृषि उपकरणों के उत्पादन पर प्रयोग होगी जो कि स्थायी एवं परिवर्तनीय लागत को कवर (सम्मिलित) कर लेगी तथा ₹ 1,00,000 लाभ में योगदान करेगी । ब्रेक्स के निर्माण अथवा कृषि उपकरणों के निर्माण में कौन-सा निर्माण अधिक लाभदायक होगा ? 12+8=20
Directive word: State
This question asks you to state. The directive word signals the depth of analysis expected, the structure of your answer, and the weight of evidence you must bring.
See our UPSC directive words guide for a full breakdown of how to respond to each command word.
How this answer will be evaluated
Approach
The directive 'state' demands clear, systematic presentation of facts and calculations. Allocate approximately 30% time to part (a) on waste management forms, 30% to part (b) on plant location factors, and 40% to part (c) numerical analysis. Structure: brief introduction, then systematic coverage of (a) and (b) with definitions and classifications, followed by detailed cost-benefit calculations for (c)(i) and opportunity cost analysis for (c)(ii), ending with a synthesized conclusion on operational decision-making.
Key points expected
- Part (a): Classification of waste management forms — industrial (hazardous, non-hazardous), municipal (solid, liquid), biomedical, e-waste; treatment methods (landfilling, incineration, recycling, composting, waste-to-energy)
- Part (b): Plant location factors — proximity to raw materials and markets, labour availability and costs, transportation infrastructure, power and water supply, government policies and incentives, environmental regulations, agglomeration economies
- Part (c)(i): Make-or-buy cost calculation: variable cost per unit = ₹260; total manufacturing cost = ₹26,00,000 + ₹2,50,000 = ₹28,50,000; buying cost = ₹25,00,000; manufacturing is NOT profitable
- Part (c)(ii): Opportunity cost analysis: compare net loss from brakes (₹3,50,000) versus ₹1,00,000 contribution from agricultural equipment; latter is advantageous
- Integrated insight: Demonstrate understanding of relevant costs, sunk costs, and capacity utilization decisions in operations management
Evaluation rubric
| Dimension | Weight | Max marks | Excellent | Average | Poor |
|---|---|---|---|---|---|
| Concept correctness | 20% | 10 | Accurately defines all waste management categories with correct technical distinctions; precisely lists location factors with operational relevance; solves (c)(i) with correct variable cost identification (₹260/unit) and proper treatment of fixed costs as unavoidable, concluding manufacturing is unprofitable; correctly applies opportunity cost principle in (c)(ii) showing agricultural equipment yields ₹1,00,000 versus ₹3,50,000 net loss from brakes | Covers major waste forms and location factors with minor errors; calculates basic costs in (c) but may misclassify fixed costs or make arithmetic errors; reaches correct conclusion in (c)(ii) but without clear opportunity cost reasoning | Confuses waste categories or omits key forms; lists generic location factors without operational specificity; fundamental errors in cost calculations (e.g., treating fixed costs as incremental) leading to wrong profitability conclusion; fails to compare alternatives in (c)(ii) |
| Framework citation | 20% | 10 | Cites 3R framework (Reduce, Reuse, Recycle) or extended producer responsibility for (a); references Weber's industrial location theory or D.M. Smith's profit-maximizing location model for (b); applies relevant costing/marginal costing framework and opportunity cost concept from managerial economics for (c); mentions make-or-buy analysis or outsourcing decision framework | Mentions one relevant framework (e.g., 3R or basic location theory) without elaboration; uses cost terminology correctly but without explicit framework citation for decision analysis | No identifiable frameworks; generic descriptions without theoretical grounding; calculations presented as isolated arithmetic without decision-making context |
| Case / Indian example | 20% | 10 | For (a): cites Indian initiatives like Swachh Bharat Mission, e-waste Management Rules 2022, or specific examples (Tata's zero-waste-to-landfill plants, ITC's wealth out of waste); for (b): references Indian industrial corridors (DMIC), SEZ policies, or specific plant location decisions (Suzuki in Gujarat, Hyundai in Chennai); for (c): contextualizes with Indian automotive sector make-or-buy trends | Includes one or two Indian examples (e.g., Swachh Bharat or any industrial state) without detailed integration; generic mention of Indian manufacturing context | No Indian examples; purely theoretical or Western-centric illustrations; examples factually incorrect or irrelevant to operations management context |
| Multi-perspective analysis | 20% | 10 | For (a): balances technical, environmental, regulatory, and economic perspectives on waste management; for (b): integrates quantitative (cost) and qualitative (social, political, strategic) location factors; for (c): explicitly considers quantitative profitability, capacity utilization, strategic control over supply chain, and qualitative risk factors; demonstrates trade-off analysis between short-term cost and long-term capability building | Covers two perspectives adequately (e.g., cost and environment for waste; cost and infrastructure for location); basic cost comparison in (c) without strategic depth | Single-dimension analysis throughout; purely descriptive for (a) and (b); narrow financial calculation for (c) ignoring strategic, operational, or risk dimensions |
| Conclusion & recommendation | 20% | 10 | Synthesizes findings across all parts: summarizes optimal waste management approach for Indian manufacturing; provides prioritized location factor framework; gives definitive recommendation for (c) with clear rationale (choose agricultural equipment, saving ₹4,50,000 opportunity cost); suggests conditions under which brake manufacturing could become viable (demand increase, cost reduction, quality/strategic considerations); ends with broader insight on capacity utilization decisions | Summarizes main points without synthesis; correct recommendation for (c)(ii) but limited justification; no forward-looking conditions or strategic insight | Missing or abrupt conclusion; contradictory recommendations; no clear stance on (c)(ii); fails to connect parts (a), (b), and (c) thematically around operational efficiency |
