Abstract:
In this independent study Value Stream Mapping Analysis of Snowflake Orange Production Process of Chiang Rai Orange Company has three objectives (1) To study about a snowflake orange production process. (2) To eliminate waste activities by using value stream mapping analysis. (3) To provide a recommendations regarding ways to increase efficiency for the company. Then, the results showed that the actual production process included 24 activities in 358.52 minutes. The process can be categorized into 3 groups (1) The process is the value-added activities which consisted of 9 activities in 192.5 minutes with a contribution of 54% of the production process. (2) The process is the necessary but non-value added activities which consisted of 9 activities in 85.51 minutes with a contribution of 24% of the production process. (3) The process is the non-value added activities which consisted of 6 activities in 80.51 minutes with a contribution of 22% of the total production process.
Based on a study, value stream mapping could effectively reduce wasting time on 4 non-value added activities. (1) To put an orange down on one side activity being eliminated from the process. (2) To order a snowflake orange into a tray activity being eliminated from the process. (3) The reduction of the draining an orange from 15.83 minutes to 10 minutes. (4) The reduction
of the cooling of the syrup from 15.17 minutes to 10 minutes. These four changes of total cycle time from 358.52 minutes to 330.58 minutes, resulting in a decreased 27.94 minutes. Moreover, to enhance snowflake orange processing, the researcher recommended such as (1) To reduce a time of the draining an orange and the cooling of the syrup activities. (2) The truck transport are parking at nearest select an orange area. (3) To change a type of refrigerator, from a top of lid to a front of lid. To reduce a damage of package and available to check stock.
By comparison, a snowflake production process using value stream mapping of the current state and the future state takes 358.52 minutes to analyze for one batch, and using value stream mapping to improve the process would be affect the number of glasses of snowflake orange. After the improved production process, number of glasses will increase from 4,320 glasses to 4,680 glasses per batch. The Chiang Rai Orange Company sells a snowflake orange price is 7 baht per glass, with the income increasing from 30,240 baht to 32,460 baht per batch which means that the Chiang Rai Company receives an additional income of 2,520 baht per batch of production.
