Exploring modularity's effects on process efficiency in single assembly line balancing
研究了装配线模块化水平对流程效率的影响，发现优化模块化能显著提升效率，最优模块化与效率间存在强正相关（平均斯皮尔曼系数0.764）。
With the growing demand to produce a wider range of products at lower costs, the modularity of assembly lines is becoming a focus of interest for manufacturers. This interest naturally arises from the assumption that modular production is one way to reduce production costs. However, these costs consist of several types of items and are influenced by various factors. For this reason, it is reasonable to replace this indicator with process efficiency. The goals of this study were to determine: (1) whether the efficiency of assembly line task processing is favourably affected by a higher level of relative modularity and (2) whether the efficiency of assembly line task processing is favourably affected by an optimal level of modularity. The results of the research presented in this article revealed that by optimising modularity, it is possible to achieve higher assembly line efficiency. The experimenters found that there is a large positive correlation between optimal modularity and efficiency, since the calculated average Spearman coefficient was 0.764. In addition, the experimental results demonstrated a fundamental difference between the relative and optimal levels of process modularity.
