Abstract

Value Stream Mapping is regarded as an important tool in the implementation of lean manufacturing. It identifies the waste in the system, paving the way for a successful lean implementation. A value stream mapping (VSM) is a paper and pencil tool that depicts a static picture of a process that allows the user to see where value is added into the value stream. Although, this method is very effective but it can be very complicated, tedious and time consuming. The traditional value stream mapping (VSM) does not have the capability to response to rapid changes which occurs in the semiconductor assembly line where the work processes change continuously. Simulation modeling is one of new approaches that Industrial Engineering (IE) practitioners are using as a powerful tool which add the dynamic aspects to the value stream mapping (VSM) and able improve the analysis time of the VSM study. The study focuses on the development of a VSM simulation model of a selected semiconductor manufacturing assembly line. The methodology adapted for the study is using the simulation modeling systematic steps, which comprised of complete steps to guide the model building of simulation based value stream mapping. The simulation model for Current State Value Stream Mapping for product SMA is developed, the model is verified and validate before it can be used for further analysis. The result of this study includes simulation scenarios of waste elimination and proposed final Future State Value Stream Mapping. The study is indeed very useful to the company because the simulation model of Value Stream Mapping is very powerful tool, where it can demonstrate the changes in the behavior of the system adhering to the inputs for the model.
