Airline crew rostering is the assignment problem of members to planned rotations/pairings for certain month. companies have monthly task constructing personalized schedules (roster) members. This became more complex and difficult while aspirations/criterias assess quality roster grew constraints increased excessively. paper proposed differential evolution (DE) method solve airline problem. Different from common DE, this presented random swap as mutation operator. The DE algorithm proven be...
The most complex aspect of people movement on emergency condition is how to select the shortest way out from multi exit ways in multi-floors building. purpose this paper demonstrate an ant colony optimization (ACO) can be used evacuation planning. Modified ACO applied as algorithm determine feasible route during evacuation. Physical obstacle building such bottleneck or disaster problem has been considered transitional probability rule ACO. By creating sign (an agent) with algorithm, agent...
Modeling human (agent) in evacuation planning is not just simply as controlling its movement but the challenge how to quantify some behavior aspects of agent flexibility. Prometheus methodology for agent-based simulation has been applied this paper develop a building. Interaction and communication during between agents through protocol capabilities showed that real can be presented computer simulation. Two scenarios according condition system, those are leaving immediately scenario finding...
Efficient evacuation of high-rise buildings is important. In the case a fire accident all occupants must move to assembly point as fast possible. Since large number are involved crowd movement be quick and accurate at every movement. Experiences from previous show that many people died because they were trapped inside building rescuer had no information track occupant. This study presents proposed model for occupant tracking in planning. Using long range RFID tags embedded on each occupant,...
A cost-based approach is developed to study the economics of operation PEM fuel cell power plants (FCPP). The includes operational cost, thermal recovery, trade with local grid, and hydrogen production. used determine optimal strategy which yields a minimum operating cost. achieved through estimating hourly generated power, amount recovered from FCPP satisfy load, that can be FCPP. An evolutionary programming-based technique strategy. tested using electrical load profiles. Results are...
Nowadays various web applications like online banking, gaming, ticket reservation etc has been utilized by the people worldwide. Existing contains a shell page which incurs high response time and inflexible is not proficient responsive. In this approach, two frameworks namely AngularJS, Joomla incorporated for conniving flexible more responsive application. AngularJS simple SPA framework with added javascript codes provides data binding formula addition, content management system manages of...
The objective of this study is twofold: (1) ascertain the viability pre-PKLI training model at SMK Bina Satria Medan's TKRO Vocational School in enhancing students' preparedness for implementation PKLI; and (2) evaluate efficacy achieving sa
Keamanan lingkungan merupakan kondisi utama untuk menciptakan suasana kerja yang kondusif dan sebagai upaya menjaga segala aset atau sumber daya dalam suatu organisasi. Semakin tinggi tingkat keamanan akan semakin rendah risiko kerugian akibat kehilangan bahaya mengancam personil. Petugas kemanan menjadi salah satu tumpuan melaksanakan fungsi-fungsi pengamanan penyelamatan. Proses monitoring kampus dilakukan secara rutin dengan jadwal patroli terjadwal umumnya memiliki klasterisasi area agar...
Increasing number of dengue cases in Surabaya shows that its city has high potential fever epidemic. Although some policies were designed by Health Department, such as fogging and mosquito’s nest eradication, but these efforts still out target because inaccurate predictions. Ineffectiveness eradication epidemic is caused lack information knowledge on environmental conditions Surabaya. Developing spread prediction system to minimize necessary be conducted immediately. Spread can improve...
Karangpilang II Water Treatment Plant (WTP) is a part of WTP Surabaya Utilities that serves the water supply for City. has biggest clean production capacity in WTP, which 2500 L/s. Using conventional treatment to remove turbidity, plant consists pre-sedimentation, clearator and filter units. In this study, evaluation turbidity quality removal efficiency were conducted analyze performance treatment. The was using 2016 data, by comparing with Quality Standard Utilities, raw water, effluents...
Pre-evacuation time is a critical phase in evacuation process. This takes big part of total time, but by simplifying this process has made some computer simulation are far away from reality. A cognitive behavior model as representation the occupant responses and actions against emergency notification built our simulation. survey order to get experiences upon situation form probability value specified according model. To improve planning, evaluations wasting consumption generous during have provided.
In Indonesia, Liquefied Petroleum Gas (LPG) is the major fuel used for cooking by households. A conversion program from kerosene to LPG implemented since 2007 has been reduced subsidy budget until 39.17 trillion rupiah per year. Unfortunately, application of new users evoked a serious hazardous behavior that may cause an explosion because inappropriate cylinder installation and non-standardized daily usages. can lead injuries, material damages, casualties. Nevertheless, most learned how use...
Pengukuran waktu kerja merupakan bagian penting dalam proses standarisasi kerja. Secara umum pengukuran dapat dibagi menjadi dua yaitu secara langsung dan tidak langsung. Pada langsung, terdapat beberapa metode salah satunya adalah Methods Time Measurements (MTM)-1. Untuk manual, perhitungan dengan MTM-1 dilakukan memilih daftar operasi yang sesuai amatan. Penggunaan table MTM oleh pengguna telah memahami gerakan serta memerlukan durasi tertentu penetapan standar harus tepat akurat...
