Critical Paths

The efficient management of energy research and development (R&D) projects is important to reduce the required the development time and cost. However, each development project is unique and innovational in nature and the duration of activities involved in an energy R&D project often cannot be predicted accurately. The uncertainty of activity duration may lead to incorrect scheduling decisions. The objective of this paper is to develop a fuzzy scheduling methodology to deal with these problems. Fuzzy variables theory is used to model the uncertain and flexible temporal information. A fuzzy scheduling algorithm with depth-first search is developed to find the possible critical paths based on fuzzy expected value simulation. A numerical example with solar photovoltaics development project is used to illustrate the effectiveness of the methodology.

In this paper, taking workshop scheduling of SMT product manufacture system for object, the conception of resource cost is incorporated with Petri Nets. The workshop scheduling model of SMT product manufacture system is build based on transition timed Petri Nets (TC-TPN). ω1 proportion of processing cost, ω2 proportion of processing time, ω3 mutation factor are chosen as the key factors using the improved heuristic A* scheduling algorithm. The result shows that: considering the processing time preference, when ω1=0.7, ω2=0.2, ω3 =0.1, the processing time is reduced by 5.83%, 3.45%, the processing time is decreased by 6.14% and 2.94%; however, considering the processing cost preference, when ω1=0.1, ω2=0.8, ω3 =0.1, the processing time is reduced by 1.94%, 0.86%, the processing time is decreased by 8.06% and 7.52%.

Load balancing of non-preemptive independent tasks on virtual machines (VMs) is an important aspect of task scheduling in clouds. Whenever certain VMs are overloaded and remaining VMs are under loaded with tasks for processing, the load has to be balanced to achieve optimal machine utilization. In this paper, we propose an algorithm named honey bee behavior inspired load balancing, which aims to achieve well balanced load across virtual machines for maximizing the throughput. The proposed algorithm also balances the priorities of tasks on the machines in such a way that the amount of waiting time of the tasks in the queue is minimal. We have compared the proposed algorithm with existing load balancing and scheduling algorithms. The experimental results show that the algorithm is effective when compared with existing algorithms. Our approach illustrates that there is a significant improvement in average execution time and reduction in waiting time of tasks on queue using workflowsim simulator in JAVA.

Valérie par Valérie opens new critical paths which are fertile, though difficult to unpack. Published under the enigmatic and collective name La Rédaction, this book – whose main (or only) author seems to be Christophe Hanna – develops what we could call a viral critique, which seeks to occupy dominant ideologies to undermine them from within rather than oppose them with a new ideology. This article aims firstly to define Hanna's viral critique, based on his own theoretical works and Guy Debord's notion of spectacle as a social and economic mechanism. It then analyzes the specific form taken by that critique in Valérie par Valérie, where the author opposes the separation of literary and non-literary forms, as well as contemporary ultracapitalism and its political-economic ramifications. Finally, the ethical implications of this type of implicit critical exercise are explored through semioethics, in order to determine the efficiency of Hanna's project.
