An Integrated Production Parameters Decision on Multi-Stage Sequential Manufacturing Through Experimental Design and Mathematical Programming

This study focuses on optimizing production parameters within a multi-stage sequential manufacturing system for the rayon fiber coagulating bath recycle process. It employs experimental design and mathematical programming techniques to address the interdependence and interactions among these stages. Unlike previous approaches that solely concentrated on single process optimization, often resulting in suboptimal designs and increased production costs due to idle time, our approach integrates the filtering, evaporating, and crystallizing processes as a cohesive system. The objective function, derived from experimental design, considers process and equipment limitations, input-output balance, and heat energy balance, with the overarching aim of minimizing production costs while meeting production constraints. To underscore the significance of our integrated approach, we provide a comparison between non-integration and our present approach, highlighting the crucial importance of this multi-stage sequential manufacturing process for enhanced efficiency and cost-effectiveness.
