Flexibility/Cost-Tradeoffs of Platform-Based Systems

چکیده
This paper provides a quantitative characterization of an embedded system’s capability to implement alternative behaviors. This new objective in system-level design is termed flexibility and is most notable in the field of adaptive and reconfigurable systems, where a system may change its behavior during operation. Different behaviors are also taken into consideration while implementing platform-based systems. Based on a hierarchical graph model which permits formal modeling of flexibility and implementation cost of a system, an efficient exploration algorithm to find the optimal flexibility/cost-tradeoff-curve is proposed. The feasibility of our approach is demonstrated by a case study concerning the design of a family of Set-Top boxes.

متن کاملManagement Insights Tradeoffs in Manufacturing? A Meta-Analysis and Critique of the Literature
There has been a considerable debate among operations strategists concerning whether managers should be advised to focus on only one of the four competitive performance dimensions—quality, delivery, flexibility, or cost. Some operations strategists argue that when a manufacturer attempts to achieve an advantage on more than one of these dimensions at the same time, a lack of strategic focus and...
