Modelling is Fast and Easy
Excel users will find What'sBest! easy to learn and use. What'sBest!
is designed to make optimization modeling a natural extension of Excel.
You can quickly build models in a free form manner using standard Excel
equations.
Begin Optimizing in Minutes
What'sBest! takes
full advantage of Excel's flexibility and ease of use. If you are
comfortable using Excel, you will probably be able to begin building
your first What'sBest! model within minutes of installations. For What'sBest!,
all of the optimization information is stored in a natural manner
within the worksheet. Constraints and relationships are expressed using
standard Excel style functions. What'sBest! models are very visual and interactive -- constraints display their status (violated, satisfied, or precisely satisfied).
Comprehensive Error Handling
What'sBest!
makes tracking down any problems in your optimization model easy. It
provides comprehensive model checking, warnings and error messages. If
a problem is encountered during the solution process, What'sBest!
provides a detailed description of the problem, and lists cell
addresses that are contributing to the problem when appropriate..
Creating a What'sBest! model is as easy as A-B-C
A - Adjustable Cells
Specify the cells in your Excel workbook that What'sBest! can
adjust to find the best solution. In traditional math programming
terms, the Adjustable cells are the variables of your optimization
problem. Your Adjustable cells may be in one neat cell range or
scattered throughout the workbook. You can allow them to take any value
or restrict them to whole numbers (i.e., integer values).
B - Best Cell
Specify
the cell you wish to maximize or minimize. In traditional math
programming terms, the Best cell is your objective function. The most
common Best cells are to minimize cost, waste, or risk; or to maximize
profit, production, or utility.
C - Constraints
Specify
the restrictions or limitations on the problem. These are the
relationships that must be satisfied for the solution to be feasible.
Examples of constraints might be the amount produced cannot exceed the
production capacity, or the amount shipped to the customer must be
equal to the customer's demand. Constraints are expressed using
standard Excel style equations, so they are easy to read and
understand. What'sBest! constraints display their status (i.e., you can see if they are violated or met).
Organize your Model on Multiple Sheets
What'sBest!
allows you to build optimization models that take full advantage of the
three dimensional modeling capabilities of Excel. The ability to
organize information over several tabbed sheets in a single Excel
workbook file can be especially useful for large models and models that
involve multiple periods or locations.
