Decision support model - DIAGRAM


Problem description


• Reason for guidelines: Managers are often under stress and make decisions by reacting to them

• Guidelines for modeling and decision support– Defining the problem– Look at potential causes for the problem– Identify alternatives for approaches to resolve– Select an approach to resolve problem

Alternatives


Decide best OS for the two proposed models: bank and shop.

Windows 7, Linux, Solaris, Mac OSX, BSD, and Windows Server

Criteria


• Hardware requirements: including RAM, HDD, GPU, CPU speed; the lowest, the better

• Possible applications that the OS can run• Security against viruses, undesirable programs and

attacks• Network capabilities of the OS needed in each model• License price when acquiring the OS• Cost of maintenance of the system

Criteria


Bank model:• Hardware requirements: Important (50).• Possible Applications: Very Important (75).• Security: Critical (100).• Network Capabilities: Critical (100).• License Price: Trivial (0).• Costs of maintenance: Unimportant (25).

Criteria


Shop model:• Hardware requirements: Important (50).• Possible Applications: Important (50).• Security: Important (50).• Network Capabilities: Trivial (0).• License Price: Very Important (75).• Costs of maintenance: Critical (100).
