Abstract

In a fiercely competitive business landscape, every company must optimize its resources and minimize wastage in the production process. At the Pressure Vessel Company (PVC), a study revealed various areas of waste, including non-compliant raw materials, delayed engineering documents, extended production times on each working floor, and lengthy material approval processes. The main objective of this research was to identify and analyze waste in the production process, as well as propose a reduction in manufacturing time. The researchers utilized eight waste tools, value stream mapping, to map the production process. The current state of the production process was documented, and eight specific wastes were identified, with the three most significant being waiting, extra processing, and motion. The analysis of the production process revealed an efficiency of only 19.13%, calculated by comparing 4655 hours of non-value-added activity to 890.6 hours of value-added activity. To improve this, changes were made to various production processes using future state map projections and proposed actions to reduce waste. As a result, non-value-added activities were reduced to 2515 hours, leading to a notable increase in production process efficiency to 35.41%. Based on the findings, several recommendations were made to enhance PVC’s operations. These include establishing a centralized office space, improving document distribution systems, building a robust IT infrastructure, and investing in ERP/SAP systems and new machinery.
