Restaurant 6431 is now open. A restaurant requires careful coordination of resources, which are the tables in the restaurant, the cooks available to cook the order, and the machines available to cook the food (we assume that there is no contention on other possible resources, like servers to take orders and serve the orders).
In this project, you will write a simulation for a restaurant. The simulation has four sets of parameters - the number of eaters (diners) that wish to enter the restaurant, the times they approach the restaurant and what they order, the number of tables in the restaurant (there can only be as many eaters as there are tables at a time; other eaters must wait for a free table before placing their order), and the number of cooks in the kitchen that process orders.Eaters in the restaurant place their orders when they get seated. These orders are then handled by available cooks. Each cook handles one order at a time. A cook handles an order by using machines to cook the food items. To simplify the simulation, we make the following assumptions. There are only three types of food served by the restaurant - a Buckeye Burger, Brutus Fries, and Coke. Each person entering the restaurant occupies one table and orders one or more burgers, zero or more orders of fries, and zero or one glass of coke. The cook needs to use the burger machine for 5 minutes to prepare each burger, fries machine for 3 minutes for one order of fries, and the soda machine for 1 minute to fill a glass with coke. The cook can use at most one of these three machines at any given time. There is only one machine of each type in the restaurant (so, for example, over a 5-minute duration, only one burger can be prepared). Once the food (all items at the same time) are brought to a diner's table, they take exactly 30 minutes to finish eating them, and then leave the restaurant, making the table available for another diner (immediately).
Input: Diners arrive at the restaurant over a 120 minute duration, which is taken as input by the simulation. If there are N diners arriving, the input has N+3 lines, specifying, in order: number of diners (N), number of tables, number of cooks, and N other lines each with the following four numbers: a number between 0 and 120 stating when the diner arrived (this number is increasing across lines), the number of burgers ordered (1 or higher), number of order of fries (0 or higher), and whether or not coke was ordered (0 or 1).
Steps to run the code:
- Run 'make' to create the jar file.
- Run 'java -jar Restaurant.jar ' to check the output
Assumptions:
- Every 100 milliseconds represents 1 minute in the simulation.
- Inputs are assumed to be correct as given in the question, else error is thrown.
