An Ant Colony Optimization (ACO) algorithm is proposed for optimal tree-structured natural gas distribution network. Design of pipelines, facilities, and equipment systems are necessary tasks to configure an optimal natural gas network. A mixed integer programming model is formulated to minimize the total cost in the network. The aim is to optimize pipe diameter sizes so that the location-alloc...

there have been several efforts in the literature to extract as much information as possible from the financial networks. most of the research has been concerned about the hierarchical structures, clustering, topology and also the behavior of the market network; but not a notable work on the network filtration exists. this paper proposes a stock market filtering model using the correlation - ba...

Redundansi jaringan sangat penting untuk memastikan ketersediaan internet dalam komputer. Spanning Tree Protocol (STP) dan Per VLAN (PVST) adalah dua metode yang dapat memberikan redundansi pada infrastruktur jaringan. Pada penelitian ini membandingkan kinerja kedua tersebut menyediakan link Perbandingan didasarkan waktu konvergensi, penyeimbangan beban lalu lintas, secara keseluruhan. Hasilnya...
