Job scheduling in grid computing is a very important problem. To utilize grids efficiently, we need a good job scheduling algorithm to assign jobs to resources in grids. The main scope of this paper is to propose a new Ant Colony Optimization (ACO) algorithm for balanced job scheduling in the Grid environment. To achieve the above goal, we will indicate a way to balance the entire system load while minimizing the makespan of a given set of jobs. Based on the experimental results, the proposed algorithm confidently demonstrates its practicability and competitiveness compared with other job scheduling algorithms.

Monte Carlo methods are a class of computational algorithms that rely on repeated random sampling to compute their results. Monte Carlo methods are often used in simulating complex systems. Because of their reliance on repeated computation of random or pseudo-random numbers, these methods are most suited to calculation by a computer and tend to be used when it is infeasible or impossible to compute an exact result with a deterministic algorithm. In finance, Monte Carlo simulation method is used to calculate the value of companies, to evaluate economic investments and financial derivatives. On the other hand, Grid Computing applies heterogeneous computer resources of many geographically disperse computers in a network in order to solve a single problem that requires a great number of computer processing cycles or access to large amounts of data. In this paper, we have developed a simulation based on Monte Carlo method which is applied on grid computing in order to predict through complex calculations the future trends in stock prices.

The rapid evolution of technology during the past decade has increased among large organizations, while at that same time they are reducing costs to retain their strategic advantage in the market. Organizations have also realized that numerous employees or cutting the size of an organization is not always a solution. Most recently, they have turned their attention to the human factor, which is renewable, to gain and retain strategic advantage inside a competitive market. The paper analyses investment in human capital, demonstrating how it is the sole solution. This paper examines knowledge employees, based on a well-structured IT department, and how they increase productivity and comprise the core of the organization structure. The leadership of an organization must administer its human resources properly to maximize the profit of their investment.
