WHAT IS IT?

(Purpose: This model simulate the Student in Cafeteria at bahria University Islamabad.Student Come in the cafeteria and sit on tables. Male and female students can not sit on the same tables. student sitting on the table will stay on it for random choosen time and then leave the cafeteria. in this model, we try to show the table and student (male and female))

State Variables and Scales

(The model comprises three hierarchical levels: students, Tables, path among the tables and location of the students. Students are characterized by the Students variables: Location and gender, males with blue color and females with red color. Tables have two variables: one is location and second is color. And in the end we describe each parameter location either table or students with distinct entities.)

Process Overview and Scheduling

(First we created breeds of male and female students. Female students are represented by red color and male students are represented by blue color. Four tables are created at different location. student initially are present at the door and only from their they can enter. from that point they move straight forward between the tables. if the table in their left or right is empty they move to that table. Color of the turtle is changed to white showing the turtle as eating in the cafy.student stay on the table until random choosen time is completed. when time is completed the student is moved to out of the cafy at a specific point and color is changed to yellow. Number of male and female student is manage by sliders. waiting time for each student is also managed by slider. )

Design Concepts

(we can adjust the numbers of students and the time, here time has two invariants one is average time to wait and second is average time for students to sit around the table. We add sliders to manage these variables and put some plots to generate report.)

Initialization

(according to the design of this Simulation, Table remain at their position. Students come in the cafeteria and decide to sit on their side according to gender division and wait for their turn. student can change their location according to avalability of the table.)

EXTENDING THE MODEL

(suggested things to add or change in the Code tab to make the model more complicated, detailed, accurate, etc.)

Emergence:

(interesting or unusual features of NetLogo that the model uses, particularly in the Code tab; or where workarounds were needed for missing features)
