A Review on Assembly Line Balancing by Different Approaches

Abstract

One of the oldest and most common production methods is the assembly line. The assembly line balancing issue is used to quickly build large numbers of a consistent product and is concerned with reducing the number of workstations, decreasing cycle time, increasing workload homogeneity, and increasing work cohesion. Assembly lines were initially created for the mass manufacture of standardized goods at a low cost. A production unit's assembly line consists of a number of employees and equipment. An assembly line is used in a manufacturing facility to produce components. During processing, the product travels along this line. For a flexible production system, assembly lines have changed over time from simple lines with a single model to mixed lines with numerous models, lines with parallel workstations, and U-shaped lines. Planning assembly lines for a system's primary goals includes balancing the assembly line according to the intended production volume each shift and reducing the number of workstations. Various assembly line balance issues (ALBP) have been researched and described in this study. Researchers can greatly benefit from the creation of a mathematical model to address the assembly line balance and scheduling issues.
