Optimizing Fish Distribution Costs at PT. Kasahi Sibolga: A Comparative Analysis of North West Corner Method and Stepping Stone Method

Introduction

The transportation problem is a crucial challenge in linear programming, focusing on allocating resources from suppliers' locations to the location of the recipient (demand) efficiently. In this context, PT. Kasahi Sibolga, a company engaged in the distribution of fish, seeks to optimize the cost of fish transportation from three sources to six destinations. The transportation method is the main tool to solve this problem, and in this study, the two methods used are North West Corner Method as the initial solution and Stepping Stone Method to test optimality.

The Importance of Transportation Methods in Logistics

Transportation methods play a vital role in overcoming complex logistics problems, and their application can significantly impact a company's operational efficiency and profitability. In the fish distribution industry, where transportation costs can be substantial, optimizing these costs can lead to significant savings and increased competitiveness. PT. Kasahi Sibolga, as a company engaged in this industry, recognizes the importance of transportation methods in achieving optimal results.

North West Corner Method: An Initial Solution

The North West Corner method is an approach that begins with giving priority to allocating from the upper left corner of the transportation matrix. In the context of PT. Kasahi Sibolga, this method facilitates the initial allocation process by setting the number of goods to be sent from each source to the destination location based on availability and needs. The advantage of this method is its simplicity, allowing companies to immediately get a fairly good solution even though not always optimal.

Key Features of the North West Corner Method

Simplicity: The North West Corner method is a straightforward approach that does not require complex calculations or algorithms.
Initial Allocation: This method facilitates the initial allocation process by setting the number of goods to be sent from each source to the destination location based on availability and needs.
Fairly Good Solution: The North West Corner method provides a fairly good solution, even though not always optimal.

Stepping Stone Method: Evaluating and Improving Initial Solutions

After getting an initial allocation through the North West Corner Method, the next step is to apply the Stepping Stone Method. This method is used to evaluate the initial solutions and find possible improvements to reduce total transportation costs. In this way, PT. Kasahi Sibolga can analyze the path that has not been allocated and transfer shipments to achieve greater cost savings. This process involves identification of paths that connect allocation points and take advantage of shifts in shipping to minimize costs.

Key Features of the Stepping Stone Method

Evaluating Initial Solutions: The Stepping Stone Method evaluates the initial solutions and identifies possible improvements to reduce total transportation costs.
Finding Optimal Solutions: This method helps to find optimal solutions by analyzing the path that has not been allocated and transferring shipments to achieve greater cost savings.
Minimizing Costs: The Stepping Stone Method minimizes costs by identifying paths that connect allocation points and taking advantage of shifts in shipping.

Results and Benefits
