Developing the Model of Managing Warehouse for Sugar Product: Case study of Phitsanulok Province, Thailand

Sugar industry is one of the processed agricultural industries that are very important to Thailand both in terms of creating jobs and income for sugarcane farmers. Sugar production period is from December to March only. It means that there are eight months in a year that the products are stored in a warehouse. The difficulties of sugar product's storage are 1) uncertainly delivery due date, 2) insufficient storage space, and 3) difficulty to relocate due to characters of the products. This study aims to analyze the system and develop a model to manage the warehouse and distribution for the sugarcane product. In this study, Value Stream Mapping (VSM) are used to analyze warehouse. After analyzing, the model which is proposed are a combination of using an industrial robot arm, hopper silo cone system, and forklift systems. After improvement, PCE of storing sugar from production is decreased by 11.25%. PCE of distributing sugar sack is increased by 55.18%. PCE of distributing bulk of sugar process is decreased by 29.08%.
