The existing production scheduling mode ignores ladle dispatching resulting in the increase of energy consumption heating and instability production. Hence, we study energy-efficient integration optimization this paper. Specifically, a mixed integer linear programming model is formulated to coordinate time-dependent correlations between them quantify them. Moreover, an enhanced migrating birds algorithm (EMBO) proposed tackle NP-hard problem. In algorithm, three-level rule-based heuristic...

To address the printed circuit board shop scheduling problem, a dynamic based on multi-indicator bottleneck degree is proposed to formulate this complex flexible job problem (FJSP).

This paper considers online energy-efficient scheduling of real-time virtual machines (VMs) for Cloud data centers. Each request is associated with a starttime, end-time, processing time and demand Physical Machine (PM) capacity. The goal to schedule all the requests non-preemptively in their start-timeend- windows, subjecting PM capacity constraints, such that total busy used PMs minimized (called MinTBT-ON abbreviation). problem fundamental parallel jobs allocation on mutliple machines, it...

When allocating virtual machines (VMs) in data centers, weights such as profits and other benefits are associated with all VMs. This paper considers maximizing the total weight VMs allocation. As virtualization widely adopted Cloud computing, requests may only consume part of capacity a single hardware resource (for example physical machine), this requires new model for weight. In paper, first time we problem shared interval scheduling proportional propose an exact efficient algorithm it...

Binary Output Systems (BOSs) generate Bernoulli distributed outputs with the given parameter. Such systems are quite common in various fields, and system performance is usually measured by success rate or correct rate. Traditional parameter optimization methods utilize approximations calculated averaging binary outputs. The used only once approximation process, little about internal relationship between different considered. In this article, we propose a novel method named Iterative...
