Manufacturing systems are constrained by one or more bottlenecks. Reducing bottlenecks improves the entire system. Finding bottlenecks, however, is a difficult task. In this study, a new bottleneck detection method based on theory of constrains and sensitivity analysis is presented to overcome the disadvantages of existing bottleneck identification methods for a job shop. First, a bottleneck index matrix is obtained by examining the sensitivity of system production performance to the capacity of each machine. Technique for order preference by similarity to ideal solution is then employed to ca

Bottleneck identification is of great interest in discrete manufacturing fields, as they limit the system’s throughput. However, the bottlenecks are difficult to accurately identify due to the instability and complexity of discrete manufacturing systems. This paper proposes a dynamic bottleneck identification method (DBI-BS) that is based on effective buffers and fine-grained machine states to identify bottlenecks accurately. First, the complex manufacturing system (CMS) with strong coupling between elements is decoupled into several independent parts under the guidance of the effective buffer

Numerous measures are being implemented to address transportation challenges in Port Harcourt, a rapidly growing city with a high population in Nigeria. The city experiences heavy traffic congestion, especially on major link roads, leading to significant delays due to the bottlenecks caused by reckless parking, construction work, and other factors. To analyse speed at bottlenecks, experts apply the Lighthill Theory, a rigorous process determining speed. Bottlenecks refer to areas in the road network where traffic flow is hindered, resulting in congestion and decreased speeds. Accurately modell

Abstract According to the Theory of Constraints by Goldratt system bottlenecks are key to improving productivity and profitability of the entire production system. An important issue in the practical application of this theory is to identify bottlenecks in the system. The aim of this paper is to develop practical steps to identify bottlenecks in the production system characterised by a homogeneous flow. The paper includes a case study which shows six steps that allowing to specify not only the first bottleneck of the system but to develop a comprehensive plan for removing bottlenecks.

While rate distortion theory compresses data under a distortion constraint, information bottleneck (IB) generalizes rate distortion theory to learning problems by replacing a distortion constraint with a constraint of relevant information. In this work, we further extend IB to multiple Markov bottlenecks (i.e., latent variables that form a Markov chain), namely Markov information bottleneck (MIB), which particularly fits better in the context of stochastic neural networks (SNNs) than the original IB. We show that Markov bottlenecks cannot simultaneously achieve their information optimality in

Abstract. Production delays at Thanksdream Garment’s pants production line, which produces jeans, stem from bottlenecks at cutting, sewing, and finishing stations. These constraints limit capacity, delay orders, and reduce profitability. The Theory of Constraints (TOC) was applied to identify and resolve these issues through steps such as identifying, exploiting, subordinating, and elevating bottlenecks.Research findings show that constraint elevation through overtime effectively increases capacity. Adding one hour of overtime to cutting station 1 raised capacity from 120,960 to 138,240 minute

On the basis of an empirical study of congestion occurring at a freeway bottleneck, it is shown that the congested regime can exist under a large variation of the discharge flow rate downstream of the bottleneck. This variation can be from about 1,600 to 1,700 vehicles/h to 2,600 to 2,700 vehicles/h per lane. A criticism of the application of queuing theories for the description of traffic pattern features is given. An explanation is given of the features of a congested regime on the basis of the recently discovered properties of synchronized flow as a new traffic phase.

The paper is mainly used to provide the equivalence of two algorithms of independent component analysis (ICA) based on the information bottleneck (IB). In the viewpoint of information theory, we attempt to explain the two classical algorithms of ICA by information bottleneck. Furthermore, via the numerical experiments with the synthetic data, sonic data, and image, ICA is proved to be an edificatory way to solve BSS successfully relying on the information theory. Finally, two realistic numerical experiments are conducted via FastICA in order to illustrate the efficiency and practicality of the

Video compression remains a challenging task despite significant advancements in end-to-end optimized deep networks for video coding. This study, inspired by information bottleneck (IB) theory, introduces a novel approach that combines IB theory with wavelet transform. We perform a comprehensive analysis of information and mutual information across various mother wavelets and decomposition levels. Additionally, we replace the conventional average pooling layers with a discrete wavelet transform creating more advanced pooling methods to investigate their effects on information and mutual inform

Identifying the bottleneck segments and developing targeted traffic control strategies can facilitate the mitigation of highway traffic congestion. In this study, we proposed a new method for identifying the bottleneck segment in a large highway network based on the percolation theory. A targeted on-ramp control approach was further developed by identifying the major vehicle sources of the bottleneck segment. We found that the identified bottleneck segment played a crucial role in maintaining the functional connectivity of the highway network in terms of meeting the required level of service.

PT. XYZ merupakan salah satu perusahaan manufaktur yang bergerak di bidang vulkanisir ban di Sumatera Utara. Pada kondisi aktual, terjadi antrean pada lantai produksi dikarenakan penumpukan barang yang diproses pada beberapa stasiun kerja atau sering disebut bottleneck. Hal ini dinilai mengakibatkan throughput pada perusahaan dalam proses yang tidak optimal. Oleh karena itu penulis merancang usulan perbaikan dengan menggunakan penjadwalan stasiun kerja berdasarkan stasiun kerja dengan upaya untuk mengeliminasi stasiun kerja bottleneck dan mendapatkan keseimbangan lintasan pada lantai produksi.

The super Toba volcano eruption in Indonesia around 70,000-75,000 years ago might have reduced the human’s world population to around 10,000 individuals. Such a dramatic scenario is indicated by the term 'genetic bottleneck theory' because the whole human species was on a global scale of nearly extinct. Here we show for modern humans and the common house mouse (strain C57bl6) they both possess a ‘chilling’ enzyme ∆12-desaturase in order to avoid that the body core temperature drops below 35.0 °C (95.0 °F). We postulate the hypothesis that the survivors of the Toba volcano eruption had been sel

Abstract. Map is an effective communication means. It carries and transmits spatial information about spatial objects and phenomena, from map makers to map users. Therefore, cartography can be regarded as a communication system. Efforts has been made on the application of Shannon Information theory developed in digital communication to cartography to establish an information theory of cartography, or simply cartographic information theory (or map information theory). There was a boom during the period from later 1960s to early 1980s. Since later 1980s, researcher have almost given up the dream

Theory of constraints (TOC) is an approach to production planning and control by focusing on the constraints of an organization to increase throughput by effectively managing constraints. TOC approach has been applied in many sectors, and efficient results have been taken. One of the application areas of TOC is product mix decisions. Product mix decisions are important for multi-product manufacturing systems because they affect the performance measures of the companies. This study aims to present how TOC is applied to determine the optimum product mix in a multiple- constraint environment in t
