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 ...

This paper proposes “path mapping”, a method of delay estimation for technology independent combinational circuits. Path mapping provides fast and accurate delay estimation using the common ideas with the tree covering based technology mapping. First, path mapping does technology mapping for all paths in the circuit with minimum delay. Then, it finds the most critical path among all the paths i...

Organizational critical activities (OCAs) are activities which must receive constant management attention in order for that organization to be successful in its industry. Some empirical studies have shown that all of these activities may not be well supported by organizations’ websites. This research attempts to develop the evaluation methodology which can be used to assess how well an organiza...

People traditionally have considered the number of counters in the critical path as the met ric for the performance of a multiplier This report presents the view that tree topologies which have the least number of levels do not always give the fastest possible multiplier when constrained to be part of a microprocessor It proposes two new topologies hybrid struc ture and higher order arrays whic...

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...

The paper investigates the effects of technology scaling on area/delay characteristics of registertransfer level (RTL) designs. Based on experimental modeling of RTL components and interconnect, whose feature sizes have been scaled down from 1.5 m to 0.25 m, we evaluate the critical path delay and area of several data-paths and report on efficiency of layout and RTL optimization techniques at t...

project planning is part of project management, which is relates to the use of schedules such as gantt charts to plan and subsequently report progress within the project environment. initially, the project scope is defined and the appropriate methods for completing the project are determined. in this paper a new approach for the critical path analyzing a project network with random fuzzy activi...
