Final answer:
To forecast the return on investment from new suppliers with better delivery records, a Decision Support System (DSS) is used due to its data analysis, simulation, and problem-solving capabilities.
Step-by-step explanation:
To forecast the return on investment (ROI) after using new suppliers with better delivery track records, you would use a Decision Support System (DSS). A DSS is an informational application that supports business or organizational decision-making activities. It provides comprehensive data, tools for analysis, and modeling capabilities that can help project the implications of changing a supplier on ROI through detailed simulations, analysis of data, and generation of scenarios.
DSS allows for the manipulation of data and assists in problem-solving, which is essential when evaluating changes in supply chain partners. Moreover, in such complex business decisions, the ability to analyze large volumes of data to predict outcomes is paramount, and that's where a DSS's computational and analytical power provides an advantage.
