Master Thesis : A Scheduling Research in Plant Factory with Considering Multi-Period Harvest
This study focus on the crop-scheduling problem for a plant factory and consider the special property of crops which can be harvested multiple times. This scheduling problem is formulated as a mixed integer programming (MIP) problem.
The objective function is defined as to find the maximum revenue for the plant factory under the consider of different practical condition including types of crops, cultivation room number, cultivation room space, heterogeneous harvesting amount among different environment of cultivation room and multiple harvesting period.
