Abstract
Di dalam situasi kecemasan, orang ramai sering mempamerkan tingkah laku tidak menentu yang boleh membawa kepada malapetaka yang besar jika tidak ditangani dengan baik. Fokus utama kajian ini adalah untuk mengkaji ejen heterogen di khalayak ramai dalam kepadatan yang berbeza, di dalam arena tertentu. Pemodelan dan simulasi ejen heterogen di khalayak ramai memerlukan pemahaman tingkah laku manusia. Apabila keadaan panik berlaku, setiap individu bertindak balas secara berbeza di mana ia bergantung kepada pelbagai faktor seperti sentuhan fizikal, emosi, daya tarikan, tempat dan lain-lain lagi. Kombinasi tingkah laku individu ini akhirnya mewujudkan tingkah laku orang ramai. Apabila keadaan panik berlaku, motivasi setiap ejen meninggalkan arena secepat mungkin dengan mematuhi peraturan pengikut, pengelompokan dan mengelak halangan. Model ini dilaksanakan menggunakan NetLogo versi 5.0.4, di mana alat simulasi ini memberi kecekapan yang tinggi sesuai untuk mengsimulasi fenomena yang kompleks. Analisis utama projek ini ialah mengira purata masa pemindahan dan kadar tindak balas untuk meninggalkan arena di bawah pengaruh dua pembolehubah. Apabila peratusan ejen B bertambah, purata masa pemindahan dan kadar tindak balas menjadi lebih baik. Manakala, apabila bilangan populasi meningkat, kadar tindak balas untuk meninggalkan arena menjadi lebih cepat, namun purata masa pemindahan menjadi perlahan. ________________________________________________________________________________________________________________________ In an emergency, members of a crowd often exhibit unpredictable behavior which can lead to major catastrophes if not well managed. The focus of this research was to study the crowd dynamics of heterogeneous agents, at differing densities, within a particular enclosed arena. Modelling and simulating the crowd dynamics of heterogeneous agents requires an understanding of human behavior. Each individual reacts differently to a panic, based on diverse factors like physical contact, emotion, attraction, sights and many others. It is the combination of these individual behaviors that ultimately affects crowd behavior. When a panic occurs, the motivation of each agent is to leave the arena as soon as possible by obeying the flocking rule, the follower rule, and obstacle avoidance rule. The implementation of this model was done using NetLogo version 5.0.4, which provided great efficiency in simulating multiple agents and is suitable for simulating complex phenomena. The analysis of this project focuses on average evacuation time and response rate to clear the arena under the influence of two variables. As the percentage of B agents (able to see 15 patches, and simulating greater knowledge of the arena) increased, the average evacuation time and response rate improved. As the population increased, the response rate to clear the arena become faster, however the average evacuation time become slower.
