“…Terdapat 2 metode optimasi, metode konvensional dan metode heuristik (Biyanto, Khairansyah, Bayuaji, Firmanto, & Haksoro, 2015). Contoh optimasi konvensional adalah algoritma algoritma Bellman-Ford dan Floyd-Warshall.…”

Industri plastik memiliki karyawan sebanyak 927 orang yang menempati lahan 12.062 m2. Jam operasional pada industri plastik untuk unit produksi adalah 24 jam non stop. Dengan jumlah dan jadwal tersebut mengkibatkan kepadatan pekerja yang memiliki risiko untuk mengakibatkan kecelakaan. Perusahaan plastik ini memiliki riwayat kecelakaan kerja. Pada perusahaan ini pernah terjadi kebakaran pada unit ABM pada bulan September tahun 2018 dan divisi bengkel pada Mei tahun 2014. Ant Colony Optimization (ACO) sangat cocok menentukan jalur evakuasi dalam penanganan bencana karena algoritma ini melakukan pembaruan pada feromon yang dapat menghasilkan simulasi dengan solusi lebih optimal karena memiliki laju konvergensi yang cepat, sehingga ACO akan digunakan dalam menentukan Jalur evakuasi terpendek pada industri plastik. Pada penelitian ini digunakan feromon awal sebesar 0,0098. Hasil penentuan parameter yang akan digunakan, meliputi number of iterations yaitu 500, number of ant sebesar 100, nilai Alpha sebesar 1 serta Beta sebesar 5 dan evaporation rate sebesar 0.5. Dari hasil optimasi cost yang paling rendah adalah cost 2 sehingga didapatkan rute evakuasi untuk ruang Circullar Loom menuju Koridor 3 dilanjutkan keluar melalui pintu exit 4 sehingga menuju Titik kumpul 1. Semakin tinggi cost yang dihasilkan maka akan mengakibatkan rute yang dilewati menajadi jauh sehingga meningkatkan waktu evakuasi.

“…When HEN is operated for a long time, however, its overall performance can be seriously deteriorated by the fouling of individual heat exchangers. Complex constituents of the crude oil and their involved high-temperature reactions can stimulate the deposition and accumulation of undesirable insulating materials on the internal surface of heat exchanger (i.e., fouling), resulting in increase of heat transfer resistance [6][7][8].…”

A moving window decision-making algorithm is proposed for the cleaning schedule optimization of heat exchanger network system subject to fouling in refinery crude preheat train. This algorithm is designed by incorporating the moving window scheme into a conventional multi-period optimal control problem (OCP) framework and has a distinct feature that it can efficiently handle a complex problem where a long-time horizon is considered. When compared with the conventional multi-period OCP method using fixed time horizon, our algorithm always shows an excellent performance regarding the computational time, still finding a compatible optimal solution. In our moving window decision-making algorithm, it is important to determine the optimal moving window size for the given time horizon as it significantly influences the optimization performance.

“…Lately, with the advancement of optimization methods and the development of meta-heuristic techniques in general and the imperialist competitive algorithm (ICA) in particular, the optimal operation of dam reservoir systems has entered a new phase. Owing to the wide scope of themes identified with water assets, different examinations on the utilization of the ICA calculation, for example, Acharya, Panda, & Lakshmi (2010); Karamouz et al (2014); Afshar, Emami Skardi, & Masoumi (2015); Hosseini-Moghari et al (2015); and Biyanto et al (2015), have been conducted.…”
