Operational research involves using mathematical models to make better decisions in complex situations. The scope includes optimization, simulation, and decision analysis. Methodology involves problem formulation, data collection, model building, solution, and implementation. For example, in supply chain management, operational research can be used to determine the most cost-effective inventory levels and distribution strategies to meet customer demand while minimizing costs.

It depends on what you are trying to model. For most models, there are specialty programs.
Value at Risk is a term used in financial modeling and risk analysis. VaR describes the maximum loss not exceeded within a specified confidence limit. There's much more information and an Excel spreadsheet at the related link below
Data analysis is a process of gathering, modeling, and transforming data with the goal of highlighting useful information, suggesting conclusions, and supporting decision making. Data analysis has multiple facets and approaches, encompassing diverse techniques under a variety of names, in different business, science, and social science domains.

The evaluation of financial data may be performed through ratio analysis, trend evaluation, and financial planning modeling. Financial planning and forecasting are facilitated if used in conjunction with a Decision Support System (DSS).
