Given the current information about the operations we will be
making some changes. There are 3 bottlenecks and we have 5
extra workers. Your goal is to get all the operations done with 7
people all working at 70 percent efficiency. In other words, all
working below 40 seconds.
The first thing to do is to fix the bottlenecks. Number 7 is the
biggest bottleneck. To fix this worker 7 will give 20.6 seconds
of their work to worker 12.
The other bottleneck is worker number 4. 7.8 seconds of their
work will go to worker number 6.
The last bottleneck is worker number 10. 9.3 seconds of worker
10's time will go to worker 2. Worker number 2 will also to the

6. job of worker 8. This eliminates worker 8.
The remaining workers are numbers 1, 3, 5, 9, and 11. All these
workers will combine. More specifically worker 11 will do all
these jobs.
Now we have 7 workers all working at an appropriate time. This
is a much more efficient way to run the operation.

Management Implementation
Project Brief
Movable Electric Stacker (Lift and Stack Pallet)
(Sample picture)

35. Project Brief
You are working as design engineer at ACK workshop. You get
a Request for Proposal (RfP) from the
School of Engineering (client). The RfP includes initially the
design of a Movable Electric Stacker model.
This model will be produced later by another production firm
that is selected by the client.
The client (represented by your professor) has no constraints
regarding the material to be used. Each
member of the design team must individually develop a design
idea, calculate reaction forces and forces at
the joints, draw it with suitable CAD software including all
necessary details, and submit it later as drawing
folder. All dimensions must be in mm. Your design team needs
to discuss advantages and disadvantages of
each design idea, decide on one of the designs using an
engineering method, and prepare the design and

36. production documents. The group final design idea must be also
analysed by using appropriate software (e.g.
Multiframe), and by performing detailed hand calculations.
Software analysis is required only for the final
portfolio technical report. All detailed workshop and assembly
drawings and documents need to be
presented and submitted to the production team by the
beginning of week 6. The necessary material needed
to construct the model must be purchased by the design team as
well. Purchased material is reimbursed by
submitting the receipts to ACK before the end of the semester.
Furthermore, in order to qualify for
reimbursement, your purchase order needs to be approved by
your professor.
Production teams must ensure that all necessary material and
information to construct the model are
received from the designer teams by the end of week 6.
Requirements:
1. A stable user-friendly product must be created.
2. The total height of the stacker with all components is 800
mm.
3. The stacker should be movable along flat surfaces.

37. 4. The forks length should not exceed 400 mm. This applies to
the straddle legs as well.
5. The forks must be lifted by using a single DC motor.
6. The cross-sectional area of each fork must be rectangular, not
exceeding the dimensions 40 mm x 20 mm.
7. The minimum lifting height of the fork is 400 mm.
8. The minimum load capacity of the stacker is 5 kg. Testing
weight has a cross-section of 400 mm x 400
mm
9. The product (lifting height) x (load capacity) must be
maximized.
10. The masts need to include trusses.
11. Joints could be either pin joints (using nuts and bolts) or
welded or a combination of both.
12. No balancing weights are allowed on the back side of the
stacker. However, stabilizing plates with a
maximum length of 150-200 mm can be used.
13. The product must not be painted and all work must be
carried out on-campus (i.e. in workshop)
14. The model has to be ready for testing at the beginning of
week 13.
15. Budget: 50.- KD per team (please hold receipts for
purchased items to submit them to Client for
reimbursement before the end of the semester).

38. Students can enter the workshop only with safety overall and
safety shoes. Using workshop machines is only
allowed under supervision of the workshop staff.
This is a team work. All team members are responsible for the
produced model.
