The project scheduling and resource allocation problems have been studied using different optimization methods. The resource leveling problem was proposed to reduce the resource fluctuation and was always studied independently resource constraint problem. For example, resource-constrained project scheduling problem (RCPSP) was proposed to optimize scheduling under resource constraints. This res...

Simultaneous optimization of time, cost, and utilized resources in a construction project is vital. This paper presents a GA based model for determination of the best combination of the time, cost, and resources in a multiple resource constraint problem. The proposed model considers both resource allocation and leveling simultaneously. Since the problem is assumed to be resource constraint, res...

Although the traditional permute matrix coming along with Hopfield is able to describe many common problems, it seems to have limitation in solving more complicated problem with more constrains, like resource leveling which is actually a NP problem. This paper tries to find a better solution for it by using neural network. In order to give the neural network description of resource leveling pro...

COVER Immunostained fl uorescence microscopy image of memory engram–bearing cells (red) in the dentate gyrus of a mouse hippocampus (image width: 1.5 millimeters). These cells were genetically tricked to express the protein channelrhodopsin-2 during memory formation, thus becoming responsive to light stimulation. When the cells were activated by light, the mice simultaneously associated a genui...

karaji has introduced and explained the leveling instruments which were used at that time, in his book inb?t? al-miah al-khafiyyat (exploration for hidden water). added to the four studied leveling instruments, karaji introduces two more; “scaled vertical level” and “scaled telescopic level” which he mentions as his own inventions. in this paper after presenting these first four, the two levels...

this paper is an attempt to shed light on the effects of modernization, urbanization, monolingual educational system, and mass media as well as the process of globalization on dialect leveling among persian dialects. in so doing, the first part of the paper elaborates on the relationship between globalization and sociolinguistics, and on the concept of standardization. also, it discusses some ...

Abstract This study aims at revising the history of knowledge management in service design organizations to discover what sources, technologies, tools, and users have been used how may thus help improve consultants’ performance. Also, this sheds light on importance decomposing (knowledge-leveling being said article) before tackling management. Moreover, provides a real case investigation organi...

Due to the limited erasure/program cycles of flash memory, flashbased SSDs need to prolong their life time using wear-leveling mechanism to meet their advertised capacity all the time. However, there is no wear-leveling mechanism among SSDs in RAID system, which makes some SSDs wear out faster than others. Once any one of SSDs fails, reconstruction must be triggered immediately. But, the cost o...
