Simple R assignment

You are to take the simulation supplement, add a order_taker, and a cashier and report the results of sandwich_maker utilization and customer wait time. This is very much like the "Subway sandwich shop" model.

Specifically, you will change the creation of the trajectory to the following

t0 <- create_trajectory("sandwich shop") %>%

seize("order_taker", 1) %>%

timeout(function() rnorm(1,2)) %>%

release("order_taker") %>%

seize("sandwich_maker", 1) %>%

timeout(function() rnorm(1, 3)) %>%

release("sandwich_maker", 1) %>%

seize("cashier", 1) %>%

timeout(function() rnorm(1,2)) %>%


To run this new simulation use the following:

env <- lapply(1:200, function(i) {

simmer("Sandwich Joe") %>%

add_resource("order_taker", 1) %>%

add_resource("sandwich_maker", 3) %>% # notice a sandwich maker can make 3 at a time!

add_resource("cashier", 1) %>%

add_generator("customer", t0, function() rpois(1, 2)) %>%

# limit run to 120 time units!



Grading Rubric:

1. No more than 3 generated pages in MS Word! Use an appendix if you need more space. (1 point)

2. You must use the provided code (1 point)

3. You must turn in your R markdown file ONLY (*.Rmd) (1 point)

4. You must use the following headers: Synopsis, Methods, Analysis, and Conclusion

Each section should make sense and contribute to the story you are trying to tell! (4 points)

5. You must show the resource utilization of the order_taker, the sandwich_maker, and the cashier (1 point)

6. You must show the wait time for the customer for the new configuration (1 point)

7. Your analysis must end with 1-5 sentences telling why you think the performance numbers changed. (2 points)

8. Your conclusion must reflect your analysis (2 points)
