This paper describes a novel method for detecting the bottleneck in a discrete event system by examining the average duration of a machine being active for all machines. The machine with the longest average uninterrupted active period is considered the bottleneck. The method is widely applicable and also capable of analyzing complex and sophisticated systems. The results are highly accurate, di...

We describe an application of belief networks to the diagnosis of bottlenecks in computer systems. The technique relies on a high­ level functional model of the interaction be­ tween application workloads, the Windows NT operating system, and system hardware. Given a workload description, the model pre­ dicts the values of observable system counters available from the Windows NT performance mon...

We present a new mechanism for detecting shared bottlenecks between end-to-end paths in a network. Our mechanism, which only needs one-way delays from endpoints as an input, is based on the well known linear algebraic approach SVD (Singular Value Decomposition). Clusters of flows which share a bottleneck are extracted from SVD results by applying an outlier detection method. Simulations with va...

With the introduction of Digital Transformation (DX) era, It is now feasible to obtain digital data not only on shop floor manufacturing facility but also across whole supply chain (SC) network for improved management. The Bottleneck (BN) first tackling point gain more throughput. By getting accumulated Lead time (LT) SC map using simulations, we could identify bottleneck regardless production ...

The complexity of today’s large-scale enterprise applications demands system administrators to monitor enormous amounts of metrics, and reconfigure their hardware as well as software at run-time without thorough understanding of monitoring results. The Elba project is designed to achieve an automated iterative staging to mitigate the risk of violating Service Level Objectives (SLOs). As part of...

Drum–Buffer–Rope is a theory of constraints production planning methodology that operates by developing a schedule for the system’s first bottleneck. The first bottleneck is the bottleneck with the highest utilization. In the theory of constraints, any job that is not processed at the first bottleneck is referred to as a free good. Free goods do not use capacity at the first bottleneck, so very...

Convolutional Neural Networks (CNNs) have been shown their performance in speech recognition systems for extracting features, and also acoustic modeling. In addition, CNNs have been used for robust speech recognition and competitive results have been reported. Convolutive Bottleneck Network (CBN) is a kind of CNNs which has a bottleneck layer among its fully connected layers. The bottleneck fea...

In this work we address the problem of inferring the presence of a capacity bottleneck from passive measurements in a 3G network. The study is based on one month of packet traces collected in the UMTS core network of mobilkom austria AG & Co KG, the leading mobile telecommunications provider in Austria, EU. During the measurement period a bottleneck link in the UMTS core network was revealed an...
