Abstract: Cycle time should be considered as a viable option when an organization is trying to improve efficiency, cost base and customer responsive. Value stream mapping is a paper and pencil tool that helps you to see and understand the flow of material and information as a product or service makes its way through the value stream. This paper proposes how a valuable tool can be implemented effectively in means of loading and unloading of the materials. A current state map is mapped for eliminating the non-value added activities, also to make a future state map for reducing the cycle time and improve the process efficiency. Keywords: Cycle time reduction, Value added and non-value added activities, Value stream mapping. I. INTRODUCTION M/s…show more content…
The team described a case where Lean Production (LP) principles were adapted for the process sector of an automotive part manufacturing plant. Value Stream Mapping (VSM) is a key lean tool used to identify the activities that add no value for various lean techniques. Current State Map is drawn to document how things actually operated on the production floor. A Future State Map is developed to design a proposed lean process flow for LP initiative on a product through the elimination of the root causes of waste and through process improvements. The use of the VSM improved the approach in LP initiatives as it reveals obvious and hidden waste that affected the productivity of D45T production. The VSM applied to assess the expected impact in the production process resulted in saving the lower rejection rates so that a positive view was induced due to the fact that there were gaps between standardized work and real work. This gap meant that workers did not follow strictly assembly standards and improvising the SOP could be a key driver in continuous improvement sustainability on the production floor as operators are fully aware on the long-term commitment to practice…show more content…
A new approach to assess lean manufacturing based on system’s variability is proposed. The assessment utilizes a new tool called variability source mapping (VSMII) which focuses on capturing and reducing the variability of the production system. This tool offers a new metric called variability index to measure the overall variability level of the system. Based on the mapping , VSMII suggests a variability reduction plan for both lean techniques as well as production control policies. Results show that this tool managed to reduce the overall variability level of the system as well as non-value added activities. This paper presented a new tool (to be added to lean improvement tools) dedicated for variability capturing and reduction. A system variability metric called variability index based on the average of overall cycle time and flow variability. It is used to track improvements achieved due to the implementation of VRP. So, it can be used as a lean metric to measure the overall wastage of the production system from a variability perspective point. So by this it is time for the lean manufacturing paradigm to take the next step by recognizing the power of variability reduction but also offers comprehensive tools to capture and manage that
