The textbook "Operations Research" by Kanti Swarup, P.K. Gupta, and Man Mohan is a foundational resource for students in mathematics, statistics, and engineering. Published by Sultan Chand & Sons, it is widely used in Indian universities for both undergraduate and postgraduate courses. Key Features of the Book

Comprehensive Coverage: The text spans a wide array of topics including Linear Programming (LPP), Duality, Transportation and Assignment problems, Sequencing, Inventory models, Queuing Theory, Game Theory, Simulation, and Network Scheduling (PERT/CPM).

Student-Friendly Language: The material is presented in simple, lucid language with a self-explanatory style.

Step-by-Step Methodology: All major algorithms are broken down into step-by-step procedures, often accompanied by flowcharts to clarify complex computational processes.

Practical Application: The book emphasizes real-life applications in business and industry, bridging theoretical concepts with practical problem-solving.

Abundant Practice Material: Each chapter includes numerous solved examples and illustrations, followed by conceptual "Test Your Understanding" questions and review exercises.

Structured Organization: The book is often divided into "Blocks" (e.g., Programming Techniques, Inventory/Waiting Line Models) to help students navigate different quantitative methods logically. Typical Book Content (By Unit) Major Topics Covered Unit I

Step-by-Step Guide: Fixing the PDF Yourself

If you already downloaded a broken copy and want to fix it, here is the quick workflow using free tools (Linux/Windows/Mac):

  1. Download the broken scan (usually from a university drive).
  2. Use Adobe Acrobat Pro (free trial) or the open-source tool ScanTailor.
  3. Rotate & Split pages: Ensure all pages face the same direction.
  4. Deskew: Remove the crooked angles.
  5. Run OCR: Use ocr.space (free) or Adobe's "Recognize Text" feature.
  6. Export: Save as "PDF/A" for preservation.

Congratulations: You just created your own "fixed" version.

6. Request a Copy via Publishers (If Allowed)

Option B: The Community Path (For those with no budget)

  1. Visit academic forums like r/FreeTextBook or IndiaStudyChannel.
  2. Search using the exact phrase: "Kanti Swarup OR filetype:pdf fixed".
  3. Crucial Step: Do not download from random pop-up sites. Instead, look for Google Drive or Dropbox links shared by verified university groups (e.g., "Delhi University Maths Society").
  4. Virus Check: Run any downloaded file through VirusTotal before opening.
