Abstract
En 中文
Cellular Manufacturing is a manufacturing strategy implemented to improve productivity and flexibility. Over the past two decades, it has shown significant effectiveness in practical applications. Its benefits include simplifying production processes, reducing production time, minimizing material handling, enhancing productivity innovation, and reducing quality issues. However, in the manufacturing of cellular systems, the issue of exceptional elements is always unavoidable. This refers to parts or operations that do not fit neatly into any single production cell and must be processed outside their designated cell. For manufacturers, there are three possible ways to deal with such exceptional elements: purchasing additional machines for the current manufacturing cell to process the parts, transporting the parts to other manufacturing cells for processing, or outsourcing the processing of the parts. However, any of these methods will inevitably increase the manufacturing costs for the manufacturer. Decision-makers must consider all potential issues to minimize overall costs as much as possible; however, few studies have addressed this in the past. This research proposes heuristic Tabu search algorithms to tackle the optimization of exceptional elements within manufacturing cells. Three models are developed: Model 1 allows partial outsourcing of part processing, while Model 2 requires full process outsourcing. The objective functions and constraints of these models account for the diversity of manufacturing cells and the treatment of exceptional elements, providing a comprehensive solution for system optimization. Model 3 apply the multi-objective function for compromising different objectives. Experimental results demonstrate the effectiveness of the proposed algorithm in finding feasible or near-optimal solutions within a reasonable timeframe, ensuring the efficient handling of exceptional elements in manufacturing cell formation.
