Question 1 (40 points): Productivity Assessment and Improvement
In this exercise, you will assess productivity with the following information as a
function of your five-digit student ID (d1, d2, d3, d4, and d5). You should replace
“0” with 10. For instance, if your ID is 49041, ➔ d1 =4, d2=9, d3= 10, d4= 4, d5= 1.

In a steel manufacturing company, a team of (10+d2) workers produced x units of
output in May 2020. They were working 9 hours per day for (20+d3) workdays in
May.
a) (9 points) Determine the labor productivity ratio using:
i. Units of output per worker-month
ii. Units of output per worker-day
iii. Units of output per worker-hour
b) (12 Points) Suppose that in June 2020, the same group of workers produced d3%
more units comparing to May 2020, but there were only 20 workdays in June. For
each productivity measure in the above parts {a.i), a.ii), a.iii)}, determine the labor
productivity index for June using May as a base. Interpret your results.
c) (8 Points) If the productivity measurement (Units of output per worker-hour)
increased by 23% from June to July 2020, How many units were produced in July
by the same group of workers, if they worked 8 hours per day for 26 days in July?
d) (11 Points) Explain in detail, how “work smart not hard” could improve
productivity in manufacturing companies? Give real-life examples and cite
appropriate references?
Question 2 (30 points): DAMES: Engineering Design Process & Ergonomic Criteria
You are an industrial engineer in a leading furniture company. Your role is to apply
an engineering design process (DAMES) to develop an ergonomic workstation for
E-Learning, that could protect students of online education from having Musculoskeletal disorders.
a. (8 points) Select and explain six ergonomic criteria that you consider as the
most relevant to compare between design alternatives of E-Learning
workstations. Cite appropriate references to support your answer.
b. (22 points) Apply (hypothetically) the DAMES steps to develop an E-Learning
workstation. Explain and illustrate in detail all the DAMES steps. In “Make
Search” describe three alternatives solutions. In “Evaluate alternatives”,
Make a table to compare between the suggested three alternatives based on
the ergonomic criteria selected in (a).

Question 3 (30 points): Anthropometric Design of a student chair
In this exercise, you will identify the appropriate anthropometric measurement to
assess the design parameters of a student chair for a classroom of mixed students
(50% males and 50 %females), See Figure 1 below to check design parameters.
Figure 1 A student chair with the following design parameters: Seat height (SH), Seat width
(SW), Seat depth (SD), Backrest height (BH), Backrest width (BW), Desktop height (DH).
a) (9 points) Based on the anthropometric dimensions presented in the slides
of Lecture 2 of week 1, Which anthropometric measurement is required for
each design parameter mentioned in Figure 1 (SD, SH, SW, BH, BW, and DH)?
Explain your answers.
b) (12 points) For each anthropometric measurement identified in (a), which
percentile(s) is (are) required for the adjustable seat design? Justify and
explain in detail your answers.
c) (9 points) Examine in detail the pros and cons of designing products for a
fixed percentage of a population. When is this approach likely to be
problematic? Cite appropriate references.
