Optimalisasi rute pendistribusian menjadi salah satu target utama perusahaan dalam pendistribusian setiap produknya. Hal tersebut bertujuan untuk mendapatkan jarak pendistribusian optimal, minimasi biaya bahan bakar, dan waktu pengiriman yang lebih cepat. Travelling Salesman Problem (TSP) menjadi salah satu masalah yang melibatkan optimalisasi proses pendistribusian produk. Dalam penelitian ini, permasalahan TSP digunakan untuk mendapatkan rute pendistribusian optimal pada PT XYZ. Metode TSP yang digunakan sebagai perbandingan adalah Branch and Bound, Nearest Neighbor, Cheapest Insertion Heuristic, dan Two-Ways Exchange Improvement. Dari hasil yang didapat menggunakan WinQSB, didapat bahwa keempat metode TSP tersebut dapat meminimalkan rute pendistribusian, sehingga biaya bahan bakar juga dapat menurun. Namun rute yang memiliki jarak terpendek berasal dari metode Two-Ways Exchange Improvement dengan selisih jarak pendistribusian sebesar 16,78 KM dan biaya bahan bakar sebesar Rp. 219.410.

The paper presents an innovative method for tourist route planning inside a destination. The necessity of reorganizing the tourist routes within a destination comes as an immediate response to the Covid-19 crisis. The implementation of the method inside tourist destinations can bring an important advantage in transforming a destination into a safer one in times of Covid-19 and post-Covid-19. The existing trend of shortening the tourist stay length has been accelerated while the epidemic became a pandemic. Moreover, the wariness for future pandemics has brought into spotlight the issue of overcrowded attractions inside a destination at certain moments. The method presented in this paper proposes a backtracking algorithm, more precisely an adaptation of the travelling salesman problem. The method presented is aimed to facilitate the navigation inside a destination and to revive certain less-visited sightseeing spots inside a destination while facilitating conformation with the social distancing measures imposed for Covid-19 control.

Travelling salesman problem (TSP) has been widely studied for the classical closed loop variant but less attention has been paid to the open loop variant. Open loop solution has property of being also a spanning tree, although not necessarily the minimum spanning tree (MST). In this paper, we present a simple branch elimination algorithm that removes the branches from MST by cutting one link and then reconnecting the resulting subtrees via selected leaf nodes. The number of iterations equals to the number of branches (b) in the MST. Typically, b << n where n is the number of nodes. With O-Mopsi and Dots datasets, the algorithm reaches gap of 1.69% and 0.61 %, respectively. The algorithm is suitable especially for educational purposes by showing the connection between MST and TSP, but it can also serve as a quick approximation for more complex metaheuristics whose efficiency relies on quality of the initial solution.
