Question 1
Problem Definition:
a. Propose and explain FOUR (4) other business and operational problems the tractor
manufacturer might be facing due to the above-mentioned inefficiencies in the internal
logistics process. Provide table and description.

Type Problem Description
Business Tractors delivered to the customers Delivery of a wrong tractor to the customer
Business The extra cost attributed to picking up
rescheduling
Pick-up missing timing with the need for
extra costs like rescheduling and
workforce.
Operational Loss of capacity and time of locating the
tractors
Lost time of locating the specific tractors
considering that the drivers need to locate
manually the tractor. Besides, manpower is
required to locate the exact tractor that
shall meet the time scheduled for the
pickup
Operational Poor accounting of tractors available in
stock
No stock on hand accountability

Operational – Poor accounting of tractors in stock
The manufacturer might not have the capacity of accounting for the tractors available in the
stockyard. There might be errors in the paper records others lost others not updated in a timely
way. Besides, stolen tractors might not be able to supply at the right time and time will be lost in
finding another tractor to deliver.
Operational – Time lost and the capacity of locating the tractors
Once there is little information where the tractor was packed last, there will be a need to conduct
a manual search inside the yard. The team in charge of logistics will have a longer lead-time for
the tractor to pick up to the pick-up point to the yard. The capacity and time will be lost since
there is a reduced labor hour of the tractors manual search thus cost reduction. For instance, the
driver cannot establish where the tractor is and the pick-up time is near, an extra workforce needs
to be allocated and still not found with a missed pick-up timing.
Business – Extra costs because of pick-up rescheduling
Once the timing of rescheduling missed but required this shall lead to extra money labor and
time. For instance, if the tractor is picked up and leading to the pick-point but misses the timing
of pick-up then the tractor will be brought back to the yard.
Business – Wrong tractors to customer’s delivery
Drivers might pick up the wrong type of tractor and its delivery to the customer. This, in turn,
leads to picking up rescheduling with an incurred extra cost of returning the tractor.

b. Prioritize and quantify those four problems in order of their impact on the business (from
high to low). Provide table and description.

Priority Type Problem Description
1 Business Tractors delivered to the
customers
Delivery of a wrong tractor to the
customer
2 Business The extra cost attributed to
picking up rescheduling
Pick-up missing timing with the need for
extra costs like rescheduling and
manpower.
3 Operational Loss of capacity and time of
locating the tractors
Lost time of locating the specific tractors
considering that the drivers need to
locate manually the tractor. Besides,
manpower is required to locate the exact
tractor that shall meet the time scheduled
for the pickup
4 Operational Poor accounting of tractors
available in stock
No stock on hand accountability

Priority 1: Delivering wrong tractors to customers
This remains the highest impact on the operations and the business. Once there is a scheduled
pick up, the driver shall locate the tractor leading to productivity and time loss. If the driver picks
the wrong tractor a rescheduling of the pickup shall be done with a required return. The
rescheduling requires an extra cost to the company with a repeat of the entire cycle.
Priority 2: Extra rescheduling pick up the cost
This remains the highest impact on the operations and the business. Once there is a scheduled
pick up, the driver shall locate the tractor leading to productivity and time loss. If the driver picks
the wrong tractor a rescheduling of the pickup shall be done with a required return. The
rescheduling requires an extra cost to the company with a repeat of the entire cycle. If the
rescheduling time cannot be located and miss then there will be pick up needed (Weinberger,
Bilgeri, and Fleisch, 2016). This process needs more cost for the whole cycle and the company
and a search for the tractor are repeated. There will be a productivity loss attributes to increased
operation cost, time and capacity.
Priority 3: Loss of capacity and time due to locating the tractors
This is the third priority considering that there exists an operational impact since more logistics
will be needs in the location of a specific tractor shipment schedule. Now, the tractors belong to
different categories and all are packed at different places in the yard. The tractors now belong to
different categories parked at different places within the yard. More lead-time and manpower and
money are invested in search of the tractors for them, not to the shipment. Any space allocated

for each category can be parked at time and labor aimed at reducing the time taken to search for
a tractor.
Priority 4: Poor tractor in stock accounting
This is the last priority since it affects the business if a person does not know the number of
available inventory tractors at hand. Once the tractors were stolen, there will be a loss of money
and assets needed in building an extra tractor.

Question 2
Workflow Design:
(a) Plan the operational workflow for the above problem. Provide a block diagram and
description.

Start
Once a tractor is demanded the supervisor assigns the category for the driver to locate then park
the pick-up tractor in the loading bay and is ready to be shipped. The process is labor-intensive
but more efficient including the IoT solution required to be put in place. First, each vehicle needs
a unique ID tag to clear the accountability that contains the necessary information like the types
of the tractor, tractor location, date it was last maintained, the date it was manufactured and the
model number.
After receiving the customer’s order, the supervisor then required to log in to the web-based
application to confirm the availability minus the hand reservation for the tractor’s category and
not send the driver to go hunt yard for the tractors, which rely on the outdated files. This is
important since it lists the visibility of the available tractor (Chachin, 2017). Once the tractor
does not carry the requested customer immediately indicating that a similar model built tractor as
per the request.
After the supervisor has extracted the required information concerning the availability of the
server, an application shall open point the exact location where the tractor is in the yard. The
supervisor requires choosing a tractor that has a reserve under the ordered number and shall not
lead to a reservation duplication. Because of the large scale in the yard breaks down into
different zones within the yard where the drivers then locate the tractor. This is an application
displaying the date of manufacturer establishing if the tractor needs preventive servicing or
maintenance before shipped to the customer. This situation assists in determining if the date of
delivery takes the most time for the tractor to get ready.
The information thus sent directly for the technician to go forward with the said task. The
technician thus scans if the tractor records and confirms the completion and start time of
maintenance servicing and prevention. After the completion, a notification sent to the team of
internal logistics notifying the tractors are ready to be shipped (Ju, Kim, and Ahn, 2016). The
team in charge of logistics thus schedules a pick-up tractor after confirming the system
notification to the supervisor and driver. The tractor driver then drives the tractor towards the
loading bay for the pick-up schedule. If there is a failure to detect the ID of the tractor inside the
yard, there will be a need for updating the server for any person to view the tractor status.
(b) Highlight and explain the conditions and dependencies of workflow activities.
Provide description.

Conditions Dependencies
Order Fulfilment Information in Real-time collected and used
by the supervisor in ensuring delivery
achieved.
Tractors in the yard location Indicate the exact stock and location
availability of tractors inside the yard
Tractors for order issuing Indicate the tractors date of manufacturing
then issue the first in first out manufacturing
date basis
Servicing or PM to be accomplished Indicate the date of last maintenance then
indicate if servicing or PM is required
Technicians maintaining the tractors Indication if the servicing or PM is required

 

Tractors ready to deploy Indication if a tractor is available then notifies
the logistics team if PM or servicing is
appropriate

Conditions: Location of the tractors inside the yard
Dependencies: The system allows searching by the supervisor in searching the tractor’s
availability after keying the specific model category and number. The process allows the
supervisor to perform a preliminary stock-checking present in the yard.
Conditions: Tractors for order issuance
Dependencies: The system indicates the tractor dates of manufacture thus issuing the tractors
depending on the manufacturing date earliest to the latest allowing tractors maximization tractors
lifespan.
Conditions: Servicing or PM to be done
Dependencies: The system indicates the last maintenance date thus indicating if servicing or PM
is necessary. This assists in determining the required longer lead time in meeting the order.
Conditions: Maintaining the tractors by the technician
Dependencies: The system indicates if servicing or PM is required and the technician assigns
tractor maintenance.
Conditions: Tractors ready to ship
Dependencies: After completion of Servicing and PM by the technician, the system notifies the
completion to the logistic team. The team in charge of logistics arranges these tractors to be
shipped out.
Conditions: Fulfilling the order
Dependencies: After the system indicating tractors availability, it checks and assigns these
orders manufactured for the specific order. The system indicates how the tractor maintained by
Servicing and PM needed. If it is not needed, the logistic team allows the preparation of the ship
outside the tractor (Yang, Zuo, and Li, 2013). However, if it is needed, the technician assigns to
maintain the tractor and informs the team in charge of logistics after completed for the logistic
team to proceed shipping out the tractor.

Type of Sensors
Checking the availability of the stock present in the yard thus installing the GPS module in every
tractor inside the yard. Once the tractor GPS does not agree with the GPS coordinate yard one
concludes that the tractor is not available inside the yard. It is concluded that the exact tractors
availability inside the yard. The coordinates of GPS use position sensors while providing the
coordinates of the Global Position System locating the tractors.
Then tag every tractor with a specific unique ID that records the inventory tractor status
providing the specific yard location. After scanning the ID tag, one then identifies the specific
tractor that can retrieve maintenance and manufacturing dates once the PM and Servicing dates
are required. The sensor presence applied at the pinpoint at the final tractor location inside the
yard with wireless RFID. After parking the tractor the driver scans then capturing location and
data once it is parked. The collected information used by the logistic team then receives the
updated data with the application.
Type of Connectivity
Every type of data as captured by the sensors collects the industrial equipment embedded system.
The analog data converts into digital form before transmission of the equipment using LoRaWan.
The one used in Singapore is AS932 containing a bandwidth of EU433 or 920-925 MHz with a
bandwidth of EU863-870 or 433.05-434.79 MHz with an 866-869 MHz bandwidth. Some of the
securities used are Application Session Key (AppSKey), Network Session Key (NwkSKey) and
Application Key (AppKey).
Type of Computing
The computing edge and fog computing used to provide real-time data analytics and data-stream
acceleration to provide feedback without any form of latency. The application of edge computing
is reducing the backhaul traffic including the central repository. Fog computing then monitors
and analyzes the received information.
Type of Application and Analytics
The cloud-based software is referred to as SaaS used in the computer that connects the devices.
This is the place where the third party hosts the application and making the data available to the
customers through the internet information connected easily and accessed easily.

Type of Sensors
To confirm the amount of stock present in the yard, one needs to install a GPS module for every
tractor present in the yard. This aspect determines the precise location of the GPS of the tractor.
Once the tractor GPS does not tally with the local address of the warehouse GPS coordinates
thus concluding that the tractor is not present in the warehouse. From this aspect, it is evident
that the exact availability of the tractors in every yard will be known. For the GPS coordinates,
one can use a position sensor that provides the coordinates of the Global Positioning System
indicating the location of the tractor.

Type of Computing
Cloud remains essential since it processes and collects data that is used since collected data from
various devices and cites are accessible across the globe. Through the integration of cloud
computing like the on-premise edge devices and fog, networks help in reducing network traffic
and improves operational efficiency. Therefore, the cloud will focus on business intelligence and
predictive analysis that involves processing a huge amount of data from the various sources
(Ziouvelou, and McGroarty, 2017). Considering the different data collected from various
warehouses it is prudent to place the best choice to compute the data.
Type of Analytics and Application
A type like SaaS is a software-based on cloud computing used by connected devices or
computers.
