Work Study and Simulation Optimization of Supply-demand Balancing in the Moth Orchid Plant Factory

摘要

This study develops a two-stage framework. An empirical study of a moth orchid plant factory is conducted. The first part includes developing the standard operating procedures (SOP) by eliminating seven muda (e.g., transportation waste, etc.) based on the lean production management for the plant factory. The second part is that we build up a simulation model of the production process via the SOP. By collecting global trade data, we estimate the supply distribution of the case factory as our output distribution and obtain the input portfolio with minimal cost by simulation optimization techniques to address the supply-demand mismatching problem.
