The search query “S. D. Sharma Operations Research Text Book Pdf Download” is one of the most common academic search strings in the Indian subcontinent. Why?
However, the reality of free PDFs:
Most websites offering a free download of this specific title (e.g., Library Genesis, PDF Drive, various .in edu-sharing blogs) host scanned, often illegible copies – missing pages, skewed tables, handwritten notes from a previous owner, or older editions (1990s) where methods have changed (e.g., revised simplex notation).

For undergraduate and postgraduate students in India and parts of Asia, Dr. S. D. Sharma is a household name in quantitative techniques and operations research. His textbook, commonly titled “Operations Research” (published by Kedar Nath Ram Nath), has been a staple for B.Com, BBA, MBA, and Economics (Hons.) programs for over two decades. Even if you get the official book, OR can be intimidating
Unlike heavier, theorem-dense American texts (e.g., Hillier & Lieberman), Sharma’s approach is problem-solution centric. The book is renowned for:
This has made the book a "gateway text" for students who fear mathematics but need to pass competitive university exams. However, the reality of free PDFs: Most websites
If the need is genuine (e.g., no library, no funds, course starts tomorrow), consider:
A typical recent edition (ca. 2015–2022) covers the following core modules, which align with UGC (India) and AICTE syllabi:
| Module | Topics Covered | Why Sharma’s treatment is distinct | | :--- | :--- | :--- | | Linear Programming (LPP) | Formulation, Graphical method, Simplex, Big-M, Two-phase, Duality, Dual Simplex | Extensive use of tables; stepwise checking for optimality. | | Transportation Problem | NWCR, LCM, VAM, MODI method, Degeneracy | VAM explained with multiple examples; degenerate cases handled explicitly. | | Assignment Problem | Hungarian algorithm, unbalanced, maximization cases | Matrix reduction steps are visually clear. | | Game Theory | Pure/mixed strategies, 2xn, mx2 games, dominance principle, LPP approach | Connects back to simplex method, reinforcing previous learning. | | Queuing Theory | (M/M/1):(∞/FIFO), (M/M/1):(N/FIFO) models | Simple derivations; steady-state equations are applied, not over-proved. | | Inventory Control | EOQ models with/without shortages, price breaks | Comparison tables for different inventory policies. | | Network Analysis | PERT and CPM – critical path, floats, crashing | Stepwise cost-slope calculation; practical project examples. | | Simulation & Sequencing | Monte Carlo, Johnson’s rule for n jobs, 2 machines | Focus on manual computation – ideal for exams without software. |
Note: Later editions also include small sections on Dynamic Programming and Replacement Theory.
