Based on the users’ multi-QoS requirements and communication time between workflow tasks,this paper presents a trust-and-cost-based comprehensive beneficial function,a strategy of determination of trust’s and cost’s weight,and a scheduling algorithm——TCD which takes trust and cost.

In this paper,by analyzing the essential characteristic of fuzzy programming and the deficiencies of the existing methods,we propose the concept of synthesizing effect function for processing objective function and constraints,and further we give an axiomatic system for synthesizing effect function.

Prediction of state variables and profit function for cephalosporin C fed-batch fermentation;

A novel approach for the on-line prediction of the profit function was proposed based on neural networks.

Research shows that the profit function is the most direct and sensitive variable of the fermentation process.

Scheduling algorithm in grid resource based on the benefit function of deadline and budget

Research on grid resource scheduling algorithm based on benefit function drive

Analyzing the features of some typical replication strategies in a collaborative data grid environment and building a benefit function that implies the collaboration among grid nodes to replace local data replication,a replication strategy is proposed taking the benefit function as basis.
