Understanding How to Practice Personal Safety Raj is a clerk at the Cool Clothes warehouse. His
supervisor has asked him to move several boxes by hand
from a truck into the warehouse. The safety manual
states the following:
"Back injuries are the most frequent and often the most
persistent and painful type of workplace injury. All work
should be carefully planned and supervised to prevent
injuries. When working with heavy equipment and
materials, employees should bend their knees and use the
large muscles of the legs to lift objects. They should avoid
using the smaller muscles of the back. They should also
make sure to wear a safety belt. Workers who do not hold
jobs that require heavy lifting should not be asked to
perform this task.”
What should Raj do to ensure that he stays safe in the
workplace?
He should make sure to bend his knees as he lifts
the boxes.
He should try to use the small muscles in his back
as he lifts the boxes.
He should make sure to wear a hard hat as he
moves the boxes out of the truck.
He should tell his supervisor he cannot do the job
because there is no way to do it safely.

Imagine us is a startup that offers high definition 3d prenatal ultrasounds for high-end customers. the service process includes four activities that are conducted in the sequence described below. (the time required for each activity is shown in parentheses): activity 1: welcome a patient and explain the procedure. (20 minutes)activity 2: prep the patient (e. g., show them to the room, apply ultrasound gel). (17 minutes) (*your id number represents the amount of time needed to complete this task)activity 3: take images. (5 minutes)activity 4: discuss diagnostic with patient. (20 minutes)at each location there are employees (servers) s1, s2, and s3. the assignment of tasks to servers is the following: s1 does activities 1 and 2.s2 does activity 3.s3 does activity 4.a. what is the capacity of this process (in customers per hour)? b. suppose 3 patients arrive every hour on average. ignoring any “start of day” or “end of day” effects, what are the utilizations of all three servers (%)? c. suppose each activity can be done by any server and any server can do any set of activities. however, each activity is done by only one server. for example, a possible assignment includes: s1 does activity 1, s2 does activity 2, and s3 does activities 3 and 4. of course, the original assignment of servers to activities is also feasible. what is the maximum capacity of the process (in customers per hour)? d. now consider the capacity measures in (c) and (a), what is the percentage change? why can you improve capacity without using additional resources? (there is no free lunch, right? )note: for all hw assignments, show your process of getting the results. only providing the final answers is not acceptable and will get 0%. if necessary, use a separate sheet of paper to show your work.
