Purpose Manufacturers and engineers need a practical and operational way to understand sustainable manufacturing and to apply it to their shop floors. The single index enables manufacturing industries to make decisions considering the continuous improvement to increase sustainability performance. The purpose of this paper is to develop a manufacturing sustainability index (MSI) based on lean and sustainability concepts using sustainable-value stream mapping. Design/methodology/approach The methodology of this research is linked to Delphi- analytical hierarchy process (AHP) qualitative assessment with sustainable-value stream mapping quantitative analysis for determining MSI. The Delphi method is used with relevant indicator selection, sustainable-value stream mapping is used to score the relevant indicator with efficiency approach and the AHP method is used to determine the indicator weight. To evaluate the applicability of this framework for assessing sustainability in the manufacturing process, a case study in Indonesian Wooden Furniture was developed. Findings The findings of this research is the framework for evaluating and assessing the sustainability performance of the manufacturing process. Although evaluation of the framework is limited to the furniture industry, there is a methodology potential to reproduce for the other sectors. Research limitations/implications Theoretically, this study has provided a single index to measure performance of the manufacturing sustainability comprehensively at factory level. However, the implementation of the developed model is too limited. More application in different sectors and different industrial sizes is needed. Originality/value The value of this research lies in the novelty of the single index in measuring manufacturing sustainability and the relevant indicators for the furniture industry in Indonesia. The selection of the indicators has involved practitioners in the furniture industry and encompassed economic, environmental and social dimensions. The visualization of indicators through sustainable-value stream mapping is proven to be more practical and helpful for industrialists.

Purpose The main purpose of this paper is to analyze the current state of a bonnet-manufacturing industry and to optimize the process by designing a future state map using simulation approach. Design/methodology/approach The case study approach has been proposed to highlight the applicability of value stream mapping (VSM) in an Indian bonnet manufacturing organization. The methodology used relies on formulation of VSM being the main tool used to identify the opportunities for classifying and eliminating bottlenecks with the help of various lean techniques. A contrast of present and past scenarios is highlighted to underscore the importance of using VSM with ARENA simulation. Findings Application of the proposed simulation approach has helped the organization reduce the cycle time significantly by 30 per cent over the entire production time. The average number of work-in-progress pieces has also decreased by about ten. In addition, enhancements have been seen with respect to ecological parameters, e.g. carbon footprint has been reduced to 83.7 percent across the process. Research limitations/implications The proposed approach of using a simulation-based VSM helps in reducing the time involved in traditional VSM method. This approach is also easy to implement at any organizational level. Practical implications It is believed that this paper will aid not just industrialists but also academic professionals to appreciate the role of simulation using ARENA in helping them understand how to attack the various problems faced by industries. The results of the study indicate that by applying this methodology, there will be a reduction not only in cost but also in environmental impacts. Originality/value The paper incorporates a real case study, which shows application of VSM for implementing lean principles in a bonnet-manufacturing industry. Break-even analysis presented fills the gap which previous literatures have been missing.

This study aims to reduce the waste that occurs on each workstation and has an impact on increasing productivity and reducing production costs caused by waste that occurs during production. The data used for this study is quantitative data obtained by direct observation to the relevant departments regarding the problem of identifying waste that occurs — data taken from observations as much as 30 times the collection of data and historical data used from January 2016 to June 2017. By using the value stream mapping method on lean manufacturing, it can be seen that there are five types of waste from the existing seven waste. The five wastes are unnecessary motion, waiting, reject, transportation and in-process processes. From the results of the value stream mapping carried out a reduction in waste on each workstation with a total reduction of waste that occurs at 66.97 tons / year or 18.6% on waste gel and 88.8 tons / year or 19.3% at waste powder and there was a reduction in the changeover process for 45 minutes or 12.16% of the total changeover time before the improvement. Also, there was also an increase in the production process speed of 2 minutes 47 seconds or 4.52% from the lead time of the previous production process, 61 minutes 34 seconds to 58 minutes 47 seconds.

Inability to fulfill the demand of consumers is becoming the major issues on citronella oil refinery in the village of Cimungkal Sumedang. This study was conducted to formulate alternative measures in order to increase the production of citronella oil distillates in the Cimungkal village. Mapping of the production process is done with Value Stream Mapping (VSM) as a first step to determine the processing time (lead time of production) and identify the waste that occurs, analyze the causes of the problems at the manufacturing level, and formulate remedial measures to increase the production of oil of citronella. The results show some activity in the production process of citronella oil which is a waste and should be minimized. By mapping, it can be seen that the lead time citronella oil refining initial amounted to 647 minutes or 10.78 hours. After repairs (Future State) improvements Total lead time to 274 minutes. Value-added activity increased by 38.93%, non-value added decreased by 3.63%, and necessary but non-value added fell by 35.3%. The study also resulted in the formulation of strategies that can be done to increase the production of oil of citronella.
