Value Stream Mapping has the reputation of uncovering waste in manufacturing, production and business processes by identifying and removing or streamlining value-added steps and eliminating non-value-added steps. The various process times for manufacturing a mono block pump were obtained from a pump manufacturing industry. The flow diagram showing the process is drawn to reflect the current state of the operation. The non-value actions are identified in each step and between each step by their waste of time and resources. The process is analyzed for opportunity to drastically reduce and simplify it to the fewest actions necessary. By reducing waste the proportion of value adding time in the whole process rises and the process throughput speed is increased. This makes the redesigned process more effective (the right things are being done) and more efficient (needing fewer resources). The reengineered process is flow charted in its future state with process steps and information flows redesigned, simplified and made less expensive. This paper addresses the application of lean manufacturing concepts to the pump manufacturing industry.

Value stream mapping has the reputation of uncovering waste in manufacturing, production and business process. This helps in identifying and removing or streaming value added steps and eliminating non value added steps. In this study the process was analyzed to find an opportunity to drastically reduce the number of actions and to simplify the same. By reducing waste the proportion of value adding time increases in the whole process and the process throughput speed could also be increased. This makes the redesigned process more effective and more efficient. The reengineered process was flow charted in its future state with process steps and information flows re-engineering, simplified and economized. The current layout was analysed to identify and eliminate the non value added activities through lean tools like 5S, VSM and line balancing in a manufacturing industry. From the observed results, it was concluded that the non value added time could be reduced by about 13% while the process cycle efficiency could be increased by about 10%. Virtual simulation was conducted to verify and validate the existing situation as well as to propose the results and the effectiveness of lean principles in a systematic manner with the help of ARENA.

The manufacturing industry is increasingly accountable for the environmental impact resulting from its activities. Research indicates that specific production processes within manufacturing plants generate significant environmental impact through energy consumption. To understand the consumption of energy in a production environment, it is necessary to outline the energy flow within the facility, along with the classification of energy usage and its relationship to processes and production outputs. It is also important to identify auxiliary (non-value added) energy within production as the area with the greatest potential for savings through changes in operational behaviour. This article introduces a practical process mapping methodology that combines energy management with value stream mapping. The methodology is based on ‘Lean’ manufacturing principles and on application to a couple of industry use cases has been shown to successfully illustrate the relationship between the energy usage and production activities for a particular value stream. Furthermore, the significant energy users in relation to the actual production process steps have been identified, and energy reduction opportunities of 42% and 50% have been quantified.

Currently the industry is trying to improve its competitiveness. This makes the manufacturingindustry needs to adapt the Lean-Kaizen concept. Lean-Kaizen means eliminating waste through small improvements made on an ongoing basis. This research takes a case study at PT Inoac Poltechno Indonesia, which is engaged in foam production. The current production target is only 56% of the planned target. Besides that, there are found many defective products and activities that have no added value. Furthermore, a map of the current condition is made to find waste and know the kaizen that will be carried out. Furthermore, a future map was developed with work standardization and Value Stream Mapping to determine activities that have no added value. Calculation of Waste Assessment Model (WAM), shows the biggest waste is defect (26.73%), inventory (15.79%), and waiting (13.35%). This study found that by adding trolley, adding operators, making SOPs, scheduling engine maintenance would make non-value added (NVA) activities decrease from 29.95% to 20.5%. Process Cycle Efficiency increased from 22.31% to 28.25% (thus fulfilling international PCE requirements for the manufacturing industry). Keyword : Lean-Kaizen, productivity, waste

The main focus when improving business processes is on the analysis of material flow. Thorough analysis of the information flow and associated information systems is still undervalued. Working with inaccurate and/or obsolete data leads to incorrect outputs that negatively affect the entire control process. Analysis of the state of material has to go hand in hand with the information analysis. A mini audit of the information flow and information system can be carried out, which follows the classic principles of VSM (Value stream mapping), in order to make an initial analysis of the information flow and information system. Information about the current state of the process together with a measure how well it is represented by the model in the information system can be obtained thanks to this mini-audit. This article focuses on this mini-audit and briefly describes the auditing process. The details of how to create VSM maps is discussed with the main focus on an information flow where the key elements are the inputs and the outputs of the job orders for planning and production management. Attention is also focused on the form of delays in discrete-event recording in the production process which appear in the information system.

Lately, value stream mapping (VSM) is integrated with tools and techniques that belong to other areas of knowledge such as risk management (RM). It is well known tool in showing the value, value stream and the flow which represents three of lean manufacturing (LM) principles. This integration, gives more benefit in covering two of VSM issues such as considering the variability and uncertainty of production processes. In this paper, a model named variable value stream mapping (V-VSM) that integrates the two was showed, explained and tested. The model helps to generate the VSM in a dynamic way with the identification of current and potential risks. These risks might happen in the future bringing a strong impact on not reaching the main objectives in the defined time and cost. The model has been tested by conducting a case study in food sector. A current state map was built using both models, traditional VSM and VVSM. The results showed the effect of variability and uncertainty on the total cycle time (CT) and lead time (LT) values, where the traditional VSM failed to show it by being a static tool. Comparing the results of both models show the differences in presenting the real state of manufacturing environment..
