Russell’s Approximation Method Dan Improved Vogel’s Approximation Method Dalam Penyelesaian Masalah Transportasi

Abstract

Distribution activities in company which related in distribution sometimes have a problems, one of the problems is transportation problem. To solve that problem can be used a transportation model to obtain the distribution route so the cost that come out is more minimum. The aim of this research is to compare the initial solution of RAM and IVAM and to know the distribution route in distribution of bottled water in the CV. Prasarana Fortuna Prima so obtained the minimum distribution costs after optimality test using MODI. The results showed that RAM gave a lower initial solution than IVAM and the initial solution of RAM was optimum after optimality test using MODI with a distribution routes is from depo Klungkung to Toko Bintang, Toko Subur, Toko Cahaya Melati, Toko Mawar Sari, and Coco Mart Ubud, from depo Kapal to CV. Sumber Jaya, Toko Sol Mandala, and Toko Kayana, from depo Mahendradatta to Toko Sinar Wangi and Toko Aris.

Optimization of Drinking Water Distribution Costs Using Vogel's Approximation Method (VAM) and Three Modified Methods of VAM (Case Study: Sikumbang Kampar Spring)

“…VAM usually produces a better initial feasible solution than the NWC and LCM methods, although it is more complicated than the two methods [16]. The steps for solving VAM [6] are to calculate the penalty for each row and column obtained based on the difference between the smallest and the second smallest values of the same row and column. Second, choose the row or column with the most significant penalty value.…”

“…Fourth, repeat the first step and stop the process when all allocations have been met. Fifth, calculate the total cost obtained [6].…”

“…Several studies have been conducted to improve VAM, including the Improved Vogel's Approximation Method (IVAM), Max-Min Vogel's Approximation Method (MM-VAM), and Modified Vogel's Approximation Method (MVAM). No theory guarantees that the initial solution is the optimal solution; to obtain the optimal solution, one of them is using the stepping stone method [6].…”

Kombinasi Metode Bilqis Chastine Erma dan Sumathi Sathiya dengan Metode Stepping Stone untuk Optimasi Masalah Transportasi

“…Beberapa metode tersebut di antaranya yaitu metode ASM (Abdul, Shaleh, Maliki) [5], revisi ASM [6], Improved Exponential Approach [7], Modified Exponential Approach [3] dan Sirisha-Viola [4]. Metode tidak langsung merupakan metode penyelesaian masalah transportasi dengan mendapatkan solusi awal [4] seperti metode Russell's Approximation [8], Improved Vogel's Approximation [8] dan Lowest Supply Lowest Cost (LSLC) [9].…”
