scheduling is to determine the priorities or arrange the activities to meet the needs, limitations and certain goals. because the time is always a limited resource, all activities should be scheduled to use optimally and certainly the resource. gravitational force algorithm, like other evolutionary algorithms, is inspired by nature. the effect of the gravity on the objects reciprocally and to a...

Competition is a ubiquitous structuring force across systems, but different fields emphasize the role of different types of competition. In benthic marine environments, where some of the classic examples of competition were described, there is a strong emphasis on interference competition: marine invertebrates are assumed to compete fiercely for the limiting resource of space. Much of our under...

The high cost of launching resources from the Earth’s surface is a significant barrier to future longduration human space exploration. A future resource economy in space may allow resource production, processing, storage, and transportation at distributed locations, but will have many stakeholders with varied and potentially competing objectives. Simulation games provide a medium for communicat...

Large scale computer networks provide access to a bewilderingly large number and variety of resources, including retail products, network services, and people in various capacities. We consider the problem of allowing users to discover the existence of such resources in an administratively decentralized environment. We describe an approach for a system that accesses the distributed collection o...

Resource sharing and allocation are important coordination problems in most processes and organizations. They are especially critical in transportation systems, where the resource to be shared and allocated is the space through which various vehicles move and the problem is ensuring that vehicles do not conflict in their use of the space—that is, that they do not collide. Transportation systems...

introduction: human resources development is one of the most important components of any organization and detecting important factors influencing human resources management plays an essential role in the success of the firms. in this study, we investigated different factors influencing human resources productivity of shiraz university of medical sciences staff. method: the present research was ...

the scheduling problems are the non-polynomial problems-hard (np-hard), is to solve it, and meta-heuristic innovative method compared with the exact method require less time and memory.in this research, developed imperialistic competitive algorithm used to solving the single-mode resource-constrained project scheduling problem.also the basic feasible solution algorithm used in order to increase...

Microbially induced carbonate precipitation (MICP) mimics the natural cementation process that occurs in various geological settings by using bicarbonate minerals resulting from bacterial metabolic pathways as cementing agents. This bio-technique can be used to manufacture so-called “bio-bricks,” which rival regular bricks strength and durability. In last two decades, MICP has been increasingly...
