What Is a Group Decision Support System?

The organizational decision support system is based on the fact that the current multi-person management decision-making activities are no longer possible or convenient to be carried out in a centralized manner. It requires computer support at higher decision-making levels and more complex decision-making environments. In a distributed environment, users can access and communicate with other users independently and in parallel from different regions through the system.

Organizational decision support systems Decision support can be divided into three categories: individual, group, and organizational. Computer-based systems can be developed to provide decision support for these levels. The organization's decision support focuses on the organization's tasks or activities, and includes a series of operations and users (such as the marketing plan and investment budget of the development department). In addition, each person's activities must be coordinated with the work of others, and computer support is the main tool for improving communication, coordination, and providing problem solving. ^[1]

(1) ODSS focuses on organizational tasks, activities, or decisions that affect departmental or corporate issues in several organizations. ^[1]

Carter et al. (1992) proposed a general structure for ODSS (see figure below). This structure differs from the traditional DSS structure (chapter 3) in several major ways. First, there is a case management component; second, through the AN, users at various locations can use DSS. Although smart parts are not included in the following figure, they can also be used as part of ODSS. A user of ODSS may run the model frequently, and each time the input is only slightly different, this will produce a lot of output and computer files. Previously, maintaining the information about these related operations was a big burden for users, and the use of ODSS was gradually reduced. The ODSS constructor recognizes that users need to support this situation, just as a DBMS has been developed to manage large databases. For example, the development of a case management system can be used to help users manage a large number of similar running cases. ^[1]

ODSS is a large and complex programming system. Its development requires a formal and structured approach, and it is not necessary to use traditional system development life cycle methods. Carter et al. (1992) proposed a method for constructing ODSS, which is SDI. The combination of C and iterative methods, the construction process is divided into four phases, the first two phases are structured and provide a framework for system development, the third phase is iterative, and contains the prototype method of system development modules. The four phases consist of two methods. These stages are: ^[1]

ODSS is indeed a unique decision support system. The main differences between ODSS and conventional DSS are summarized in the table below. Here are some important ODSS implementation issues: ^[1]

Essential difference between ODSS, GDSS and DSS

The essential differences between ODSS, GDSS and DSS are: ^[2]

The goal of ODSS is to support the decision-making process of an organization. A decision-making process may include multiple decision-making sub-tasks, and the completion of support for the decision-making process will involve multiple units and members of the organization; on the contrary, GDSS is only carried out between several members of the decision-making team for a certain decision-task Collaborative decision-making without involving interactions between decision-making subtasks;

All the decision-making activities involved in the decision-making process are distributed at multiple levels and multiple departments in the organization. The internal connection between decision-making activities determines that the participants must work together. ODSS uses computer technology, communication technology and artificial intelligence technology. Improve the efficiency of collaborative work;

Achieve efficient sharing of data, models, and decision-making knowledge within the organization;

ODSS must not only provide important decision-making information to decision-makers, but also need to provide multiple coordination mechanisms to support the interaction between decision-makers and the efficient execution of related decision-making activities.
