## 5 Discussion  
In the contemporary business environment, manufacturing companies are compelled to enhance their performance in order to maintain their competitive advantage. In order to compete, it is imperative that they enhance their productivity by improving the quality and reducing costs and delivery times. Material feeding systems represent a pivotal dimension that exerts a significant influence on productivity. The selection of appropriate materials feeding systems in manufacturing companies has been shown to result in a decrease in non-value-added work and quality problems, an increase in product output, an improvement in ergonomic conditions, and an enhancement in the ability to respond promptly to customer demands. A wide range of material feeding methods have been listed in the extant literature, including line-storage, Kanban, kitting, demand-based, just-in-time, and hybrid approaches. Kanban is a material feeding system based on drawing the minimum and maximum stock defined. A notable advantage of this method is that it does not necessitate any additional planning. It is predicated on the assumption that the requisite stock quantity is available at the stipulated location. The line-side feeding method is advantageous in that materials are available next to the assembly line and can be easily accessed in case of any problem; however, it is disadvantageous in that it takes up space next to the line, and the time spent searching for materials is not value added. In contrast, the on-call demand-based feeding method involves the request of materials from a central warehouse when they are to be used in the assembly line. The requested materials are delivered in a box, the required amount of material is consumed, and the remaining material is delivered back to the assembly line. Despite the lack of spatial proximity to the assembly line, this method results in inefficiency due to the movement of materials. Kitting is a material feeding method that ensures that the materials required for the assembly line are placed in a defined quantity in a defined container and delivered to the specified place at the specified time. This method is considered advantageous in enterprises where product variety is high and product demand volume is low. The reduction in material intermediate stocks has been shown to decrease the time spent searching for components. It has been demonstrated that kitting can increase productivity by reducing non-value-added activities. It also helps to prevent incomplete or incorrect assembly by providing a defined and visual management system. However, it is important to note that this method does come with certain disadvantages, including the requirement for dedicated kitting preparation time and labor. Inadequate implementation or a less developed kitting system within the supply chain can result in assembly line downtime. This study was conducted at a manufacturing company specializing in the production of hydraulic and pneumatic motors and agricultural and industrial vehicles. The company deploys cellular manufacturing techniques and has five distinct product groups, with the selected product group encompassing three separate assembly lines. The company is engaged in the production of motors, characterized by a high degree of product variety and a comparatively low-demand volume. A comprehensive investigation was conducted into hybrid approaches that may be suitable for the company, with a focus on Kanban, line-storage feeding, call-out, and kitting systems. While the requirement for additional space for new machines and assembly lines is acknowledged, there is also a demand to increase the number of outputs through enhanced productivity of assembly operators. Additionally, there is a requirement for a material feeding system that is straightforward to implement, capable of expeditious decision-making, and conducive to assembly lines with diverse value streams within the factory environment.
