A Model for Computer Configuration Design

Trivedi, Kinicki
1980 Computer  
Concentrating on the hardware components of a computer configuration, the question addressed here is how to choose the devices for a batch-oriented, nonpaged multiprogramming computer system.  ...  The computer system is represented by a closed queueing network, and the design problem is formulated as a nonlinear optimization problem which includes both system cost and system performance.  ...  With the degree of multiprogramming n as a fixed parameter, the following two optimization problems are defined with respect to the m + 1 variables (r,So): It should be noted that the device speeds are  ...
