Spreadsheet modeling

Definition

Spreadsheet modeling is the process of using spreadsheet software to create a dynamic representation of a system or process, allowing for analysis and decision-making through manipulation of variables and data. This technique is widely used for solving material balance problems, especially those involving multiple species, because it enables easy calculations, visualization of relationships, and scenario testing to understand the impact of changes in input parameters.
