Abstract

A Study of "Lead Time Reduction for New Regular Slotted Carton (RSC) Development and Production" begins with the study of various processes, working methods, and time consumed in activities for designing and manufacturing new products. The scope of the study covers from receiving information from customers to delivering products to customers per their request. The objective of this research is to reduce the overall lead time by at least 15%. The data from the study of various factors affecting on time consumption and time losing were analyzed and examined for the root causes by using industrial engineering techniques, 7 quality tools, Roll paper analysis, queuing management system and productivity improvement techniques. It was found that the workflows in both material and information caused queuing. The insufficient quantity from production line was a cause of repeated production. The Loss of overall equipment effectiveness due to various causes was also the duplicated work. The improvement was approached by analyzing the work flow, then using Pareto charts to prioritize the data. Moreover, the improvement activities were accomplished by using appropriate techniques. After the improvement, it was found that lead time was reduced by 29.08% from previously 3,250 minutes to be 2,305 minutes, totally decreased by 945 minutes. Along with the reduction of Lead time, it also reduced in some of the non- value activities on workflow. The case study can enhance the competitiveness of the factory which affected to the customer's satisfaction.
