Abstract Vehicle scheduling is one of the most important links in logistics distribution, a large number of demands also lead to logistics companies have to reasonably arrange the transportation of vehicle routes to save costs. By optimizing the distribution routes of vehicles, logistics companies can save transportation mileage and thus save transportation costs. In this paper,10 demand points of an agricultural products logistics company in Beijing are selected, and the location of the distribution center is obtained through the center of gravity method. Finally, the route allocation is completed by using the mileage saving algorithm, and the scheduling of transport vehicles is realized. The example shows that the mileage saving algorithm can optimize the vehicle route and realize route allocation.

Center Location

Customer clustering technology for distribution process is widely used in location selection, distribution route optimization and vehicle scheduling optimization of power logistics distribution center. Aiming at the problem of customer clustering with unknown distribution center location, this paper proposes a clustering algorithm considering distribution network structure and distribution volume constraint, which makes up for the defect that the classical Euclidean distance does not consider the distribution road information. This paper proposes a logistics distribution customer clustering algorithm, which improves CLARANS algorithm to make the clustering results meet the constraints of customer distribution volume. By using the single vehicle load rate, the sufficient conditions for logistics distribution customer clustering to be solvable under the condition of considering the ubiquitous and constraints are given, which effectively solves the problem of logistics distribution customer clustering with sum constraints. The results state clearly that the clustering algorithm can effectively deal with large-scale spatial data sets, and the clustering process is not affected by isolated customers, The clustering results can be effectively applied to the distribution center location, distribution cost optimization, distribution route optimization and distribution area division of vehicle scheduling optimization.

At present, the pharmaceutical logistics industry in our country is still not perfect, and the pharmaceutical logistics enterprises have not occupied the home of advantage in China. Establishing pharmaceutical logistics distribution center can make well coordination with production, transportation and other aspects, so that the upstream and downstream enterprises can complete the delivery mission, shorten the logistics time, reduce logistics cost better. The actual data of import goods in this paper to Zhongyou of pharmaceutical logistics company in Gansu at present as the basis, use the association graph method to design the best layout of distribution center, draw the final layout, make reasonable arrangements for each functional area location, shorten the walking path, improve the distribution center operation efficiency, so as to provide quality service delivery for each customer, in order to meet the needs of daily doses of whole northwest area.

Abstract To meet the rapid demand for pharmaceutical drugs, a new warehouse is needed to distribute to various cities in West Java. This research at PT. Kimia Farma has the aim of determining the location of a new warehouse that is efficient and effective in minimizing the transportation costs of PT. Kimia Farma Plant Bandung to the location of distribution in West Java. The current conditions with warehouses in the city of Bandung prove that transportation costs at the company are very large, due to the distance from the old warehouse to the distributors. In this study, the Center of Gravity method is used to determine the location of the warehouse. The design of this research is a case study in the area of West Java with data collection methods such as interviews and using CorelDraw software to create a Cartesian diagram. The calculation results obtained using the center of gravity method for the location of the new warehouse located in Subang with coordinate points (18.36). With the new warehouse location, it can minimize transportation costs as much as Rp. 481,192 with a percentage reduction of 6.76% and the distance from the initial warehouse in Bandung to Subang and then to all distribution destinations, which is 43 km closer after the addition of new warehouses. and has a decreased percentage of 6.91%. Abstrak Untuk memenuhi permintaan obat-obatan farmasi yang cepat, maka dibutuhkan letak gudang baru untuk mendistribusikan ke berbagai kota di Jawa Barat. Penelitian pada PT.Kimia Farma ini memiliki tujuan menentukan letak gudang baru yang efisien serta efektif dalam meminimkan biaya transportasi PT.Kimia Farma Plant Bandung ke letak distribusi di Jawa Barat. Kondisi saat ini dengan gudang di Kota Bandung membuktikan pengeluaran biaya transportasi pada perusahaan sangatlah besar, dikarenakan adanya jarak tempuh yang jauh dari gudang lama menuju para distributor. Dalam penelitian, digunakan metode center of gravity dalam mentukan letak gudang. Desain penelitian ini berupa studi kasus wilayah jawa barat dengan metode pengumpulan data berupa wawancara serta menggunakan software CorelDraw untuk membuat diagram kartesius. Hasil perhitungan yang diperoleh menggunakan metode center of gravity untuk letak gudang baru berletak di Subang dengan titik koordinat (18,36). Dengan adanya letak gudang yang baru maka, dapat meminimkan biaya transportasi sebesar Rp.481.192 dengan persentase penurunan sebesar 6,76% dan jarak tempuh dari gudang awal di Bandung menuju Subang lalu menuju semua tujuan distribusinya yakni sebesar 43 km lebih dekat setelah adanya penambahan gudang baru dan memiliki presentase penurunan sebesar 6,91%.
