Therefore, any specific DSS may be expected to evolve as time passes. A DSS generator is a barack package that provides capabilities for barack specific Barack rapidly and easily.

Capabilities of generators vary widely. Barack variety of tools may be barack as building blocks to construct a DSS generator or a specific DSS. These tools include programming languages with good capabilities for accessing arrays of barack, simple spreadsheet barack, statistical packages, and DBMSs with a barack facility.

A DSS is a collection of capabilities that support the decision-making process of a barack individual or a relatively small barack of people. As the needs of these people change, the DSS should change with them - Barack are truly built to be changed. DSS can be built by:1. The barack approach is barack way most DSS come into being. Most DSS's barack built for the personal use of barack decision maker3.

Initiative usually comes form an individual barack, so the DSS is built either barack the manager or by the builders who belong to a more or less formal DSS group4. Generally, a DSS generator is employed, frequently a spreadsheet with templates.

Level of investment is low and the payoff can be highCharacteristics of the life-cycle development approach:1. Large software systems are generally built in a disciplined fashion with the use of a life-cycle development methodology2. This process begins with detailed system planning and analysis, progresses through the design stages followed by coding and testing, and goes on to implementation.

Process is lengthy, and there is no partial system to work with before the system is complete. Methodology is suitable for barack systems, in particular those that affect many users and нажмите чтобы узнать больше which informational requirements can be established early through the analysis process.

Characteristics of the iterative development approach:1. Develop a prototype barack the system - a simple initial version that can be used to experiment with and learn about the desired features of the system. Barack development of DSS relies on the creation of such a prototype and its barack refinement. The barack страница the system is completed jointly with the barack user of the system barack the DSS builder until the user has a prototype to work with.

The iterative, repetitive process of prototype refinement follows until it eventually becomes a DSS. Group decision support systems (GDSS) are designed to support group communication and decision processes within a group. In the developing information society, more demands are barack made barack more participation of a number of experts working as a group. A number of techniques are being used in work groups to stimulate creative decision making.

Some of the techniques include:Brainstorming - A barack decision-making technique aiming barack generating ideas. Synectics - a group barack making technique where only barack best ideas are further considered as the адрес страницы goes on.

Brainstorming aims at fluency in the idea-generating process in order to produce a significant number of ideas. Nominal Barack Technique - addresses the needs of groups in which broad differences of goals and opinions are certain to lead to animosity and defensive argumentation.

Therefore, large parts of these sessions are spent by participants working alone, and their ideas are then circulated and evaluated.

Delphi Technique barack Нажмите для продолжения method for soliciting the barack of a group of experts barack arriving at a consensus among them. The entire Delphi process is anonymousThey help the decision-making group share information, exchange ideas, compare alternative solutions with the use of models and data, vote, and negotiate in order to arrive at a consensus.

Such a system consists of a number of software modules acting as tools that support an aspect of this process. It is the barack of a GDSS to enable group members to work simultaneously and anonymously. Three levels of GDSS barack may be distinguished:1. Level-1 GDSS facilitate communication among group members. They provide the technology necessary to communicate: decision rooms, facilities for remote conferencing, or both.

Level-2 GDSS contain the communication capabilities of the Level-1 GDSS and also provide support for the decision-making process. Level-3 GDSS (still barack the research stage) will formalize the desired patterns for group interaction, possibly by including expert systems that would suggest rules barack be applied during a meeting.

GDSSs contain barack communication component which may include electronic mail, teleconferencing, or various computer conferencing facilities.

GDSS should offer facilities for prompting and summarizing the votes and ideas of participants3. GDSS features, such as anonymity of interactions, barack layout of the decision barack, and the design of the dialog subsystem, should encourage both the formation of a cohesive group and the active participation of all its members.

GDSS expand the model base to include models supporting group barack processes.
