The new invention is a system for specifying spreadsheets, business plans or other numerical plans using a structured text format, also known as a domain specific language (DSL), and a grid-valued machine. The DSL is both human-readable and can be interpreted by a computing system to create a spreadsheet or related outputs, including the calculation of business metrics. The grid-valued machine is a new model for a computer fitted to this purpose, where a grid of values is used as the underlying data model (i.e., as opposed to the normal register machine model). The language can include terms for describing uncertainty, allowing the specification and presentation of stochastic plans, e.g. for risk analysis. This can be supported in the grid-valued machine using a Monte Carlo approach with multiple grids.
