This paper proposes a hybrid ACO approach to minimize weighted tardiness for a batch-processing machine in diffusion area with incompatible jobs and dynamic arrival time. The method combines ACO algorithm and NACH (Next Arrival Control Heuristic) method, and also puts the batching and scheduling process together. The proposed method is validated and verified by extensive simulation experiments. The...
A novel approach to scheduling resolution by combining Autonomic Computing (AC), Multi-Agent Systems (MAS), Case-based Reasoning (CBR), and Bio-Inspired Optimization Techniques (BIT) will be described. AC has emerged as a paradigm aiming at incorporating applications with a management structure similar to the central nervous system. The main intentions are to improve resource utilization and service...
Robust scheduling is an effective way to solve job-shop scheduling problem (JSP) under a dynamic and stochastic environment with uncertainties, which may lead to numerous schedule disruptions. Maintaining the optimization obtained, the robust schedule is more stable in execution. The vast majority of the researches on robust scheduling concentrate on the development of the robustness and stabilization...
The flexible scheduling of business process is crucial in the developing of enterprises, many researchers focus on the scheduling strategies, and many strategies were proposed. In this paper, eight classical scheduling strategies were introduced simply. The definition and some properties of compound number were mentioned in some short. We mainly discussed the application of the scheduling strategies...
Dynamic scheduling algorithms are gaining more and more special attention for their satisfying robustness when confronted with unexpected events as well as their considerably high performance in scheduling. The wasp colony algorithm is a newly presented dynamic scheduling algorithm, which bases on natural insect society behavior models. Based on the principle of the wasp colony algorithm, two different...
Enhanced Uplink operation of WCDMA-UMTS systems utilizes fast Node B scheduling and a short Transmission Time Interval (TTI) of 2ms. The scheduling decisions are based on scheduling information (SI) sent by each UE to the Node B. The main drawback of the current scheduling procedure is that the SI does not include any information regarding the delay sensitivity of each traffic flow, as well as the...
