Supply chain is the set of entities that are involved in the design of new products and services, producing raw materials, transforming them into semi-finished and finished products and delivering them to the end customers (Kaliani Sundram et al., 2016). Supply chain management is one of the most essential aspects of conducting business. many people outside of the direct community do not realize this because an ordinary consumer often experiences only its effect. One of key aspects of a successful company is the ability to quickly and effectively react to changes in the supply chain (Lu, 2015).

Figure 1 . Supply-Chain Process

Maintaining high customer service standards by adapting to demand, controlling costs related to materials, production, and shipping, managing risks both internal and external, maintaining strong supplier relationships to mitigate issues like material shortages, and addressing employee retention issues that could lead to understaffing and loss of expertise. Balancing these factors helps businesses remain competitive while navigating operational complexities and economic uncertainties (15 Key Supply Chain Challenges to Overcome).

The logistics of supply and distribution involve two key processes: the supply of materials from external suppliers or a remote factory to a production site, and the distribution of products from the factory to customers The relationship of logistics to supply chain management: developing a common industry definition. From a logistics perspective, the supply of materials and the distribution of products are nearly identical, and similar methods can be employed for their planning and management. The distribution system is influenced by the type of products being shipped. For example, investment goods such as machines or equipment are typically shipped infrequently along specific transport routes. In contrast, materials used in production are delivered regularly and frequently along the same paths. Consumer goods, often shipped to wholesalers or retailers, are usually delivered in very small order sizes, with some businesses averaging shipments below 100 kg Route planning module as a part of Supply Chain Management system.

AI approach to the problems of supply chain management for example route planning is effectively called Route Optimization that starts with an optimal route, the optimal route is the shortest geometrical path between two points in a space is the path with the minimum distance between them, defined by its weight and length. There’s some condition why we use optimal routes like significantly enhancing operational efficiency, reducing cost, and minimizing environmental impact Supply chain sustainability (SCS).

Figure 2. Example of Optimal Route from Place to Place

Our team uses Dijkstra Algorithm to define bestest / optimal route if we want to do task in different places at the office, the algorithm often used in finding shortest path, geographical maps, find location of map which refers to vertices of a graph, distance between the location refers to edges, IP routing, and telephone network. From the image we try to find best route from home to office by using road length data, and the shortest path is symbolized as red line.

Figure 3. Dijkstra implementation in our Office

From Figure 3, we start drawing our office map and give every path we used to walk by giving it some nodes. the picture shows the shortest way from bedroom to restroom with different stops, the path shows in red line. The story of the path is, I want to go from bedroom(6) to bathroom(2), but before that I want to play in playing room(1), eat in living room(5), going to kitchen(4), going bathroom(2), and back to my desk(5).
