4. Writing Timeline

5. A Writing Example: Truck Operation Lei Deng, Mohammad H. Hajiesmaili, Minghua Chen, and Haibo Zeng, “Energy-Efficient Timely Transportation of Long-Haul Heavy-Duty Trucks,” IEEE Transactions on Intelligent Transportation Systems (TITS), vol. 19, no. 7, pp. 2099-2113, July 2018.

6. Planning: Preparing materials • Category 1: Present your own technical result • Of course, you need to have your own result first • Search and read related work • My truck example belongs to this category • Category 2: Summarize others’ technical results • Search and read materials on the topic • Technical books • Technical papers: IEEE, ACM, etc. • Internet • Others

7. The Truck Example: Problem Statement • Objective: minimize the fuel consumption of travelling from to • Constraint: a hard deadline • Design Spaces: route planning and speed planning

8. The Truck Example: Our Results 4. Show up to 17% fuel saving, as compared to fastest/shortest path algorithm, in simulations using US highway data 1. Show Energy-efficient timely transportation is NP-Complete 3. Propose a heuristic with complexity ; it is optimal under a condition 2. Propose an FPTAS with approximation ratio and complexity is the number of edges, is the number of nodes

9. Organizing: Writing outline • Divide the paper into sections • Abstract • Introduction • Related Work • System Model • Problem Formulation • Main Results • Simulation • Conclusion • Reference • Appendix

10. Organizing: Writing outline • Divide each section into paragraphs • Introduction Section • Background • Motivation • Contributions • Paper Organization

11. Outline of The Truck Example • Abstract • Introduction • Related Work • Model and Problem Formulation • An FPTAS for PASO • A Fast Dual-based Heuristic • Performance Evaluation • Conclusion and Future Work • References

12. Introduction Outline of The Truck Example • Heavy-duty trucks deliver most of goods and consume huge energy. It is important to reduce the energy consumption of heavy-duty trucks. • Two lines of work to reduce the energy consumption of trucks • Line #1: Design more fuel-efficient trucks • Line #2: Operate trucks more economically • Route planning: choose more fuel-efficient route/path • Speed planning: slow down the truck • However, slowing down the truck can increase the travel delay. Timely delivery is also critical to the truck operations. • We study the energy-efficient timely transportation problem for heavy-duty trucks. • Our contributions: • Propose the energy-efficient timely transportation problem and prove that the problem is NP-complete • Propose an FPTAS with approximation ratio and complexity • Propose a heuristic with complexity ; it is optimal under a condition • Show up to 17% fuel saving, as compared to fastest/shortest path algorithm, in simulations using US highway data

13. Writing: Expanding According to the Outline • Expand each summarized sentence into a paragraph in the outline • Then you have the whole paper!

14. The Truck Example • Heavy-duty trucks deliver most of goods and consume huge energy. It is important to reduce the energy consumption of heavy-duty trucks.

15. The Truck Example • Two lines of work to reduce the energy consumption of trucks • Line #1: Design more fuel-efficient trucks • Line #2: Operate trucks more economically • Route planning: choose more fuel-efficient route/path • Speed planning: slow down the truck

16. The Truck Example • However, slowing down the truck can increase the travel delay. Timely delivery is also critical to the truck operations.

17. The Truck Example • We study the energy-efficient timely transportation problem for heavy-duty trucks.

18. The Truck Example • Our contributions: • Propose the energy-efficient timely transportation problem and prove that the problem is NP-complete • Propose an FPTAS with approximation ratio and complexity • Propose a heuristic with complexity ; it is optimal under a condition • Show up to 17% fuel saving, as compared to fastest/shortest path algorithm, in simulations using US highway data

19. Reviewing: Proof-reading the whole paper • Note: before the final reviewing, you may have many back-and-forth editing of planning/organizing/writing so as to fix the organization, logic, and contents. • In the final review/proof-reading, check • Spelling • Grammar • Punctuation • Reference format • Other parts what are not related to organization/logic/contents

20. Proof-reading Tips • Print out the REAL paper rather than electronic one • Proof-reading paragraph by paragraph • Finish one paragraph in enough times until it has no problems and then go to next paragraph • Read out each word

21. Importance of Title/Abstract/Introduction

22. How to Write Abstract • An abstract must be a fully self-contained, capsule description of the paper.  • Parts of abstract include • Motivation: why do we care about the problem • Problem Statement: what’s the problem? • Approach: how do you solve the problem? • Results: what’s your results/answers to the problem?

24. Ten Rules for Technical Writing

25. Rule 1: Search Before Using • Use search engines (Google, Yahoo, Bing, Baidu, etc) to see whether it is commonly used in English world

26. Rule 2: Do not Join Independent Clauses by a Comma, but by a Semicolon

27. Rule 3: Omit Needless Words

28. Rule 4: Use Transitions • Time: before, after, during, while, until • Space: above, below, inside • Cause and Effect: because, since, as a result/consequence, consequently • Similarity: as, likewise, similarly, similar to • Contrast: although, however, on the other hand

29. Rule 5: Prefer the Active Voice

30. Rule 6: Express Co-ordinate Ideas in Similar Form

31. Rule 7: Avoid Long Subject-Verb Distance

32. Rule 8: Prefer Short Sentences

33. Rule 9: One sentence focuses on one point; One paragraph focuses on one topic • If you follow the outline-driven writing procedure, one paragraph naturally focuses on one topic. • If you avoid too long sentences, one sentence is likely to focus on one point.

34. Rule 10: Tense Consistence (Source:Internet)
