Calculation Set Format

The specific organization and content of a calculation set are given.

While the format and contents cannot be rigidly specified because of the wide differences in character of problems and solutions, the following format should be followed to the extent it is possible.  A project will typically be subdivided into many little problems with the following calculation format repeated for each problem identified.

The specific contents of each of the items in any calculation set format outline are described below.

1. Problem Statement

A statement of the problem or objective of the calculation proceeding the solution permits ready reference to the conditions and data known about the problem.

2. Process Sketches

Diagrams are used as an aid in visualizing problems. Sketches should be large enough to include basic data without excessive crowding. Sketches may be free-hand but must be legible. Use of a straight edge and templates is preferred.

3. Plan of Attack

Outline a general plan of attack for the solution. State your solution plan in words before calculating with numbers. Frequently there are alternate design or analysis methods available, and it is critical to know which has been employed. Thus, it is extremely important that the design/analysis methods employed be clearly recorded in the calculation set.

4. Basis of Calculations

Unless the basis of calculation is explicitly stated, it is often difficult to determine how to compare the solution to another solution which may have a different basis. If it is necessary or convenient to change basis within the body of the calculations, clearly indicate the change of basis.

5. Body of the Calculations

Detail should be tailored to the requirement for clarity. The detail content should be sufficient so that any qualified person could follow the step by step sequences and locate both the sources and destinations of information without the need to make their own calculations. Specifications on the calculation format are given in the following section.

6. Error Analysis

Cross checks of the calculations.  Verification of assumptions and their effect on the results.  Comparisons to other data/information.

6. Conclusions

Clearly state any conclusions drawn from the results of the calculations.

7. Nomenclature

Explicitly define all variables used in the solution of the problem. The units of all variables must be stated.

8. Information Sources

Give a list of complete references for all sources included in the problem solution.
