Description:
In this paper, design structure matrix (DSM) methods are presented to manage design iteration or rework which is inherent in the design process. Three DSM methods: path searching, powers of the adjacency matrix, and reachability matrix methods are discussed. Their advantages and disadvantages with respect to the project scope are summarized. As a case study, DSM methods are implemented to reduce the design iteration or rework in a complex engineering project. The main advantage of the DSM methods over traditional project management tools such as CPM or Gantt chart is in compactness and ability to present an organized and efficient mapping among tasks that is clear and easy to read regardless of size.
Description:
Multistage interconnection networks (MINs) have been widely adopted in communication networks especially in telecommunication and multiprocessor environments. This paper aims to evaluate the reliability performance of shuffle exchange network with an additional stage (SEN+), based on Monte Carlo method using computerized simulation. The evaluation is further improvised by deploying stratified sampling into the Monte Carlo method. SEN+ described in this paper is confined to multiprocessor environment based on identical switching elements used in interconnecting multiple processors. It is shown that Monte Carlo method is capable of providing reliability evaluation for SEN+ system.
