Abstract: In grid computing, resources are used outside the boundary of organizations and it becomes increasingly difficult to guarantee that resources being used are not malicious. Also, resources may enter and leave the grid at any time. So, fault tolerance is a crucial issue in grid computing. Fault tolerance can enhance grid throughput, utilization, response time and more economic profits. All mechanisms proposed to deal with fault-tolerant issues in grids are classified into: job replication and job checkpointing techniques. These techniques are used according to the requirements of the computational grid and the type of environment, resources and virtual organizations it is supposed to work with. Each has its own advantages and disadvantages which forms the subject matter of this paper.

Abstract: Business performance and multi-objective decision support systems play a critical role forsurviving in a strongly competitive global market. Accurate business performance evaluation is akey to strength enterprises competition. In this paper, we collect the financial indices of therelevant literatures for analyzing the relationship among the indices. Four different abilities are commonly considered when analyzing the financial health of a company--liquidity/Debt-paying, financial structure/Stability, activity/efficiency, and profitability. Each one has different indices for measurement. In total, there are 11 indices included (e.g. Current ratio, Quick Ratio, Debt to Total Assets Ratio, Permanent Capital to Fixed Assets Ratio, Accounts Receivable Turnover, Average Accounts Receivable Collection, Fixed Asset Turnover Ratio, Total Asset Turnover Ratio, Return on Assets, Return on Equity, Net Profit Ratio). In order to select better performance indices, we adopt structural equationmodel (S
