The processing time of operation and duedate are represented by fuzzy numbers and the satisfaction degree of customers is presented for showing the degree that the completion time is satisfying with customers. Then using the operations and evaluation criterions of fuzzy numbers, multi-objective fuzzy job-shop scheduling problem is defined and studied.

Min-min algorithm, a classics algorithm in heuristic algorithm, which always completes the shortest total completion time task first, has the characteristic of simple and shortest completion time. So it catches a lot of close attentions in the field of studying for tasks scheduling algorithms in Grid.

The properties of cost, quality and supporting resource were added to an activity. And the completion time, cost and quality measures of an activity were defined as the function of activity-supporting resource.

To formulate a project scheduling between coordinator and negotiating partners in virtual enterprise, not only factors such as project completion time and feasibility, but also project expense, should be considered.

Job shop scheduling problem is well known to be a difficult, strongly NP-complete problem, the objective of this is minimizing the completion time of all the jobs, called the make span, subject to the constraints of this kind of problem.

We present the main concepts and steps of the method. Queueing modeling and steady-state operational analysis techniques are also used for analytic modeling. Both simulation and analysis studies on the HT-7 data processing system indicate that in comparison with conventional time-shared systems,a client/server system can significantly reduce the completion time of raw data display,real-time data processing and data transfer in the online system,raise the workload capacity and reduce the average waiting time of the off-line system.

In heterogeneous parallel computing systems based on message passing, every processor or computer has capability of scheduling and executing jobs autonomously and independently. For high performance computing, a processor, which originally has a divisible job, can call other heterogeneous processors for co computing with load sharing so that job completing time can be decreased. In this paper, a scheme for load sharing in heterogeneous computing is presented. Firstly, invoking load sharing protocol,...

In heterogeneous parallel computing systems based on message passing, every processor or computer has capability of scheduling and executing jobs autonomously and independently. For high performance computing, a processor, which originally has a divisible job, can call other heterogeneous processors for co computing with load sharing so that job completing time can be decreased. In this paper, a scheme for load sharing in heterogeneous computing is presented. Firstly, invoking load sharing protocol, the originating processor collects available data such as load sharing interval time and computing power from its partners. Secondly, a function is constructed which represents the relationship between the total job magnitude and the job completion time. The function is essential for choosing a suite of appropriate processors, optimally partitioning and scheduling jobs, as well as minimizing the job completing time. Finally, an efficient algorithm is proposed through the examples in application and experiments. The algorithm is real time at the moment when the job is just started, and can be extended to the situation of multiple jobs originated at multiple processors.
