Material Requirements Planning for Chiangda Vegetable Tea Production: a Case Study in the Plant Genetic Conservation Center of Khlongpai, Nakhon Ratchasima Province

Abstract

Chiangda vegetable is known as a Thai herb whose properties that help regulate blood sugar level in diabetic patients as well as to control body fat balance, and has been processed in the form of Chiangda vegetable tea. The problem of insufficient production of Chiangda vegetable tea that did not meet the consumer demand has led to the objective of this research to plan about the demand of raw material of Chiangda vegetable tea for the Plant Genetics Center, Khlong Phai [Plant Genetic Conservation Project Under the Royal Initiation of Her Royal Highness Princess Maha Chakri Sirindhorn (RSPG)] by applying MRP (Material Requirements Planning) theory to find more accurate amount of Chiangda vegetable that would be needed for the tea production. Data were collect from herbal tea department and general administration department for studying, followed by analyzing relevant information from the collected secondary documentation, such as: purchase order records, sales records, raw material purchase orders, production records, product components, and participant observation by the staff from herbal tea department in order to find the effectiveness. After the MRP system was introduced, it was found that the material quantity for production volume stipulated clearly. It also makes Chiang da tea products sufficient for customer demand, resulting in increased sales from 2018 to 36.00% from the year on. The executives could therefore propose the promotion policy for effective raw material requirement planning
