Simulation of Dining Philosophers
In this project we use the dining philosopher system as our main example. Four Chinese philosophers
are sitting around a circular table. In the middle of the table there is a delicious dish of rice, and between each pair of philosophers there is a single chopstick. Each philosopher alternates between thinking/resting and eating. To eat, the philosopher needs two chopsticks, and he is only allowed to use the two which are situated next to him (on his left and right side). The sharing of chopsticks prevents two neighbors from eating at the same time.
The philosopher system is modelled by the CPN tools software as shown below:
About the system:
|4 places||2 forks and 2 knifes|
|4 places||4 philosophers|
|4 transitions||Eating activity for each philosopher|
|4 transitions||Resting activity for each philosopher|
Note: At any moment in the system, maximum any two non-neighbor philosopher can either eat or rest, and the other two are resting or eating respectively.
