PT XYZ as the best and largest Bed Sheet Set company in
Indonesia with products such as Bed Covers, Bed Sheets, Pillowcases, Bolsters
and Blankets. The Traveling Salesman Problem (TSP) is a problem faced in
finding the best route to visit shops that sell products from PT BIG. A visit
to the shop is carried out on the condition that each city can only be
visited once except the city of origin. The algorithms applied in this TSP
problem include the Complete Enumeration, Branch & Bound and Greedy
Heuristic methods. |

INTRODUCTION
PT XYZ, a company engaged in garments, especially the
largest Bed Sheet Set & Bed Cover in Indonesia with product brands A and B (Faisal,
Hardianto, Dwichwanto, & Septiana, 2021). These products are
widely used by every community and have been spread in several big cities such
as Subang, Sukabumi, Bogor
and Bandung (Firman,
Herlina, Paturochman, & Sulaeman, 2018). In the process of
distributing products in each city, human labor is needed, one of which is
through Sales Promotion (Susanto
& Sunardi, 2017). Sales Promotion offers
products to stores in big cities to sell products to consumers (Larissa,
Yuwono, & Mardiono, 2017). The distribution of
products in each city has obstacles in delivery with the distance from the city
far enough (Chandra
& RAHARDJO, 2013) so that the delivery
of goods takes quite a long time (Putra,
Nyoto, & Pratiwi, 2017). If product delivery
takes a long time, it will result in delayed product delivery (Miradji,
2014) and product marketing
cannot be done quickly (Toyib,
Onsardi, & Muntahanah, 2020). For this reason, the
company must be able to develop a plan to be able to create inter-city routes (Zulfikar,
Mayvita, & Purboyo, 2019) that can minimize
delivery time by arranging product delivery routes (Karundeng,
Mandey, & Sumarauw, 2018). So that product
marketing can be done effectively (Artaya
& Purworusmiardi, 2019). The problem that
will be discussed is that there is no optimal delivery route (Tanujaya,
Dewi, & Endah, 2013) with the minimum
total distance or cost and determining the best route (Muhammad, Bakhtiar,
& Rahmi, 2017). Determination of
delivery routes using Complete Enumeration, Branch & Bound and Greedy
Heuristic methods.
RESEARCH METHODS
Data collection needed for this research, the authors
use the following methods: (Pratama, Rahaningsih, Nurhadiansyah, & Purani,
2019)
1. Literature Study. The author collects materials as
references from modules, journals, articles, internet on Complete Enumeration,
Branch & Bound and Greedy Heuristic Methods.
2. Field Study. The author observes directly in the field
based on the required data.
3. Data Collection. The data is taken based on the city
that is often visited by sales and based on the distance traveled by the city.
4. Data Processing. The data is processed by analyzing
problems in finding the shortest route using the Complete Enumeration, Branch
& Bound and Greedy Heuristic methods.
5. Finding the Optimal Solution. Optimal solution is
obtained based on the calculation of the shortest route. The shortest route
deserves to be the Optimal Solution because it is more efficient.
RESULTS AND DISCUSSION
PT. XYZ will assign Sales
Promotion to visit shops that sell products from PT. XYZ (Firmansyah, SE,
Anita Roosmawarni, & SE, 2019). These shops are located in the cities of Subang, Sukabumi and Bogor (Taufiq, 2016). Determination of Sales Promotion travel routes in
each city is obtained based on the distance of each city (Wijaya, Kristianto,
Vanel, & Huwae, 2020). The data retrieval used will later be processed
and determine the closest distance that will later be taken Here are the
distances between cities: (Amri, Rahman, &
Yuniarti, 2014)

Based on data collection,
the city of origin of the sales promotion is Bandung. Sales Promotion will
travel to visit the store. The stores are located in the cities of Subang (1), Sukabumi (2) and
Bogor (3). Sales Promotion requires the shortest distance in order to maximize
travel and minimize costs. From these problems, the data was processed using
the Complete Enumeration, Branch & Bound and Greedy Heuristic methods. Here
are the results of Data Processing:

The results obtained using
the Complete Enumeration method with the shortest distance of 373 km.
The results obtained using
the Branch & Bound method with the shortest distance of 373 km.
3. Greedy
Heuristic Method
Figure 3. Results of Greedy Heuristic Method
The results obtained using
the Branch & Bound method with the shortest distance of 386 km.

Based on the Complete
Enumeration Method, the results obtained with a distance of 373 km. The Branch
& Bound method obtained results with a distance of 373 km. The Greedy
Heuristic method obtained 386 km results because it is different from the
Complete Enumeration Method and the Branch & Bound Method which can pass
through which city first as long as it does not pass through the city of
origin. In the Greedy Heuristic Method from the origin of the city the closest
distance is chosen then from the city that is being occupied to the next city
the closest distance is chosen.
CONCLUSION
Based on the results of the analysis and distance
determination, it is found that the Complete Enumeration and Branch & Bound
methods are better methods than the Greedy Heuristic method. This is because
the distance traveled by determining the Complete Enumeration and Branch &
Bound has the same distance of 373 km, while the Greedy Heuristic Methods
method has a further distance of 386 km.
