Abstract: When it comes to deciding on significant matters pertaining to their businesses, a large number of businesses and organizations rely on what are known as decision support systems (DSS). Both the theory and practice of decision support systems are continuing to advance, and they are occasionally converging with other significant advancements in information technology (IT), such as organizational computing, e-commerce and business, and pervasive computing. A well-designed decision support system is an interactive software-based system that assists decision-makers in identifying problems, finding solutions to those problems, and making decisions. This assistance might come in the form of raw data, documentation, personal expertise, or business models. Building decision support systems around the concept of providing the people who will use them with the tools that will assist them in analyzing data, applying models and databases, and finding viable answers to the problems they face is the primary focus of the development of these systems. Bringing attention to recent developments in decision-making assistance systems is the primary objective of this research. In addition, we discuss both the positive and bad sides of utilizing a decision support system, all of which are essential concepts to know in order to avoid repeating the same errors twice. In the very last step, but certainly not the least, we discuss the scenarios and the many forms of decision aids. This was accomplished by providing an in-depth summary of more than fifteen separate investigations.
