It should be pointed out that other spreadsheets such as Lotus and Quattro Pro also provide a similar optimization model also developed by Frontline Systems, Inc Microsoft Excel Solver Installation As stated earlier, Solver is an Excel Add-in tool available from TOOLS/SOLVER If the Solver is not available, then it could be due to: (1) Solver is installed but not selected or (2) Solver is not installed Solver is installed but not selected If Solver is installed, then from the TOOLS menu select ADD-INS This will display all the available ADD-INS as shown in Figure 1. For additional information the reader is encouraged to visit the Frontline web site at The site contains links to the most current information on the Solver platforms, examples, tutorials on different optimization models, although not much on least squares application to surveying problems. In addition to the standard Solver, Frontline Systems provides Premium Solver Platforms to handle very large optimization models including a DLL Platform which can interface with Visual Basic and C/C++ programming languages.

Solving an optimization model using Excel Solver requires: Identifying model resource data Specifying the constraints for the model Specifying the model objective The above three steps are carried out through the Solver s GUI dialog box.

Furthermore, the user does not need to know (1) how to form the condition equations (2) how to differentiate complex equations (3) how to solve the normal equations used in a conventional least squares approach. Since the solution of least squares problems requires minimization, Excel with its strong Graphic User Interface (GUI) provides a convenient and readily available tool, the Solver, to adjust small to medium size traverses encountered in day to day surveying practices. 1.1 About Microsoft Excel Solver The Excel Solver Engine, developed by Frontline Systems, Inc., is a standard feature of any Microsoft Office product. The models include a single traverse loop and interconnected traverse loops where observations are independently weighted. This paper describes various techniques for modeling survey traverse data to be adjusted by least squares. INTRODUCTION Solver is an Add-in tool in Microsoft Excel designed to perform optimization solutions for modeling systems. Traverse Adjustment Using Microsoft Excel Solver 1/20ģ Traverse Adjustment Using Microsoft Excel Solver by: Surveying Engineering Department Ferris State University, Big Rapids, MI USA 1. The paper also provides some useful Visual Basic functions used in traverse adjustment. The data transfer to and from Excel is very flexible.

Excel is readily available in any Windows platform without any additional cost.

The reasons the use of Excel for traverse adjustment can be considered a viable option are: a. This paper provides: a brief overview of Excel s Add-in Solver basic theory of least squares as implemented within the Solver advantages and disadvantages of the Excel Solver in least squares, and two numerical examples outlining the steps involved in carrying out a traverse adjustment. Although several least squares adjustment packages are available, Microsoft Excel provides another option for performing a rigorous least squares traverse adjustment.

However, when a traverse becomes more complicated with multiple junction points yielding redundancies greater than three, Compass Rule or Transit Rule adjustments will not be able to do an effective job, particularly when observations (distances and angles) have different weights. 1 Traverse Adjustment Using Microsoft Excel Solver by: Surveying Engineering Department Ferris State University, Big Rapids, MI USA Traverse Adjustment Using Microsoft Excel Solver 0/20Ģ Traverse Adjustment Using Microsoft Excel Solver by: Surveying Engineering Department Ferris State University, Big Rapids, MI USA Key words: Traverse Adjustment, Least Squares, Excel Solver Abstract Simple two-dimensional traverses can easily be adjusted using Compass Rule or Transit Rule.
