Identify the pattern of reducing production time losses by mapping the future situation in TaghBist Steel Structures Company

The implementation of lean manufacturing in industrial units has a direct impact on enhancing the competitive position of those units and their profitability. In other words, reducing the production time, which occurs by reducing hidden and obvious losses and smoothing the workflow, provides much time and production resources to the industrial unit and indirectly reduces the cost of finished products. Value stream mapping is one of the supports and application planning techniques for analyzing and designing process chain configuration and is one of the most important lean manufacturing implementation tools for many industries. The purpose of this research is mapping the value stream for the TaghBist metal structures company, analyze its operations and manufacturing processes, and provide practical suggestions for improving the value chain to reduce production time and costs losses. The results of the lean production implementation in the production process show that the total lead-time of the manufacturing processes reduced from 3835 seconds to 3480 seconds. In addition, the number of assembly line stations reduced from eight to four. As a result, the reduction in the production time and the number of stations have led to the conversion of the manufacturing system from compression to stretching, reducing production costs, as well as reducing the number of operators in the production line.
