Bottleneck-based heuristic for permutation flowshop scheduling
… newly heuristic is developed by introducing the bottleneck-based concept that was applied at the beginning of initial solution determination. The heuristic is known as Bottleneck-Based (BNB) heuristic. The previous study found that the scheduling activity become complex when dealing with large …

Type-2 Fuzzy Logic: Circumventing the Defuzzification Bottleneck
… it has come to be known as the defuzzification bottleneck. The computational complexity derives from the enormous number of embedded sets that have to be individually processed in order to effect defuzzification. Two new approaches to type-2 defuzzification are presented, the sampling method and …

Throughput analysis and bottleneck management of production lines
… doing preventive maintenance tasks based on the bottleneck ranks with an objective of improving the throughput of a plant which consists deteriorating machinery. Unlike the previous bottleneck management approaches, APMDSS anticipates the system dynamics (i.e., bottlenecks, hourly buffer levels, …

Computing Exact Bottleneck Distance on Random Point Sets
… sets of points containing n points each, in a bottleneck matching problem, we want to find an one-to-one correspondence, also called a matching, that minimizes the length of its largest edge; the length of an edge is simply the Euclidean distance between its end-points. As an application, …

Optimising data centre operation by removing the transport bottleneck
… throughput, usually by filling up queues at the bottleneck. However, for most applications within a data centre network latency is more critical than throughput. Consequently the choice of transport protocol becomes a bottleneck for performance. My thesis is that the solution to this is to move …

Unsupervised connectivity-based cortex parcellation using the information bottleneck method
In this dissertation, we embody an information-theoretic framework to compress and therefore cluster anatomical connectivity data that avoids many assumptions and drawbacks imposed by previous methods.

Breaking the bottleneck in radiation materials science with transient grating spectroscopy
Nuclear power applications are characterized by harsh mechanical, chemical, thermal, and irradiation environments that present a challenge for the materials engineer. Nuclear materials research and development is a subject of managing constraints: a component must be proven to retain its integrity …

Secrets of the Aluminati: Bottleneck Assessment within an Aluminum Rolling Mill
This work demonstrates how heuristic-based capacity estimation techniques were used to determine the utilization of the preheat process of Commonwealth Rolled Products (CRP), an aluminum rolling mill. CRP wished to evaluate its processes to determine whether its present capacity was compatible with …

Minimization of weighted tardiness in job shops using shifting bottleneck and tabu search procedures
… two well known heuristics, namely the shifting bottleneck procedure and tabu search. Both heuristics are known to perform very well for minimizing makespan in job shops. Here we adapt them for the objective of minimizing weighted tardiness and test both under different parameter settings in …

FCoder: A real-time large-scale bottleneck detection mechanism with neural network and transfer learning
Detecting shared bottlenecks among network flows is crucial in TCP Multipath to ensure TCP fairness and other applications related to cross-flow congestion control. The problem of whether two flows share a bottleneck has been well investigated in previous work, but a large-scale bottleneck …

Bottleneck identification in cycle time reduction and throughput improvement efforts in an automotive transmission plant
… methodologies is the identification of process bottlenecks. The techniques for identifying bottlenecks that are suggested by many improvement methodologies are no more than simple heuristics. These simple heuristics may prove inadequate in a complex manufacturing environment. This thesis asserts …

Static and dynamic job-shop scheduling using rolling-horizon approaches and the Shifting Bottleneck Procedure
… dealing with this problem. Adapting the Shifting Bottleneck (SB) procedure is a third approach that has motivated many studies. Most research focuses on optimizing a certain objective function under idealized conditions and thus does not take into consideration system disruptions such as machine …

Overcoming the domestication bottleneck in soybean: mapping domestication traits and using wild soybean to improve diversity
… Evaluation of G. soja-Derived Lines The genetic bottleneck caused during the domestication of soybean significantly reduced genetic diversity, as soybean landraces only contain half of the genetic diversity found in G. soja populations. Considering the narrow genetic base found within North …

Male genital tract versus blood HIV-1 compartmentalization and selection: the first step of the transmission bottleneck?
… widely accepted idea of an HIV-1 transmission bottleneck. The nature of this bottleneck is not fully understood. Many studies working on understanding the nature of the transmitted virus have reported discordant traits of transmitted/founder viruses compared to viral isolates from chronically …
