A natural generalization of the criticality notion in a network with fuzzy activity times is given. It consists in direct application of the extension principle of Zadeh to the notion of criticality of a path (an activity, an event) treated as a function of the activities duration times in the network. There are shown some relations between the notion of fuzzy criticality, introduced in the pap...

Critical Path method (CPM) is widely used in project scheduling and controlling. In conventional project scheduling problem, the crisp numbers are used for the activity times. But in reality, in an imprecise and uncertain environment, it is an unrealistic assumption. To represent the uncertainty involved we have considered the interval-valued numbers to represent the activity times. In this pap...

Modern processors come close to executing as fast as true dependences allow. The particular dependences that constrain execution speed constitute the critical path of execution. To optimize the performance of the processor, we either have to reduce the critical path or execute it more efficiently. In both cases, it can be done more effectively if we know the actual instructions that constitute ...

Critical Path Profiling is a technique that provides guidance to help programmers try to improve the running time of their program. However, Critical Path Profiling provides only an upper bound estimate of the improvement possible in a parallel program execution. In this paper, we present a new metric, called Slack , to complement Critical Path and provide additional information to parallel pro...

T In this paper, we propose an approach based on hardware-software partitioning to minimize logic area of a SOPC circuit "System on a Programmable Chip". This approach minimizes the SOPC area while satisfying a time constraint. To minimize this area, we propose an algorithm to determine the critical path with the largest number of hardware tasks in a given data flow graph. Once these hardware t...

A systematic procedure for locating resistive bridges is presented. Critical path tracing is used to identify a set of “suspect” bridges whose presence could explain all of the observed faulty behavior of the circuit for the original test set. The set of suspects is then reduced by adaptively applying additional tests derived from the failing vector pairs in the original test set. Unlike other ...
