Extended Abstract
Lean manufacturing is a method used by Toyota to eliminate or reduce waste to reduce production time and decrease production costs. Eliminate, Combine, Rearrange, Simplify (ECRS) are used to eliminate, combine, rework and simplify the non-value-added activity. This paper proposes lean manufacturing, ECRS, and TRIZ to reduce waste and increase production efficiency. The results of implementing lean manufacturing with ECRS and TRIZ in this study will contribute to the literature on ways and solutions for more effective and efficient improvements so that it can be helpful in industry and academics in the future. Meanwhile, the Theory of Inventive Problem Solving (Theory of Resheniya Izobreatatelskikh Zadatch, TRIZ) is helpful for systematically solving or reducing waste based on data and contradictions.
Keywords: ECRS, Lean Manufacturing, TRIZ, Waste.
1. INTRODUCTION
Industry demands for improvement or innovation are increasing along with the development of global information and technology. Companies must be able to adapt and improve themselves with more effective and efficient improvement methods. Improvement methods such as lean manufacturing also need to carry out continuous development to be even more effective over time. The company makes continuous improvements in the production process to increase consumer desire and satisfaction (Palange and Dhatrak 2021).
2. METHODOLOGY
This paper reviews journals about lean manufacturing methods. The journal used is the latest journal from 2017- 2021, which discusses lean manufacturing and its combination with other methods. Papers that can be used are only papers that use the lean manufacturing method with the ECRS or TRIZ method in solving manufacturing company problems. After collecting several suitable journals, then they are analyzed, draw conclusions and recommendations for future research. The authors did this study to make it more descriptive. This research is based on several previous studies to understand better how lean manufacturing processes have evolved.
3. RESULTS
As a result, we attempt to advocate combining lean manufacturing with the ECRS and TRIZ methodologies for reducing waste in this study. When lean manufacturing is combined with ECRS and TRIZ to reduce key waste and develop improvement solutions based on innovative challenges, lean manufacturing can identify waste that causes losses to the business. TRIZ can provide solution in the improvement of waste that have not been able to be solved by the ECRS approach using 40 inventive principles and 39 engineering parameters. for example, combining the ECRS and TRIZ methods, such as the ECRS method, proposes rearranging or simplifying a waste problem; therefore, combining the two ways will result in a more effective solution. The ECRS approach will support the TRIZ method in making judgments to eliminate, combine, reorganize, and simplify significant waste derived from lean manufacturing in this example. Why is it considered to be more effective? Because TRIZ will propose answers based on the engineering parameters provided, eliminating the requirement for a trial-and-error approach to finding a solution to the problem.
4. CONCLUSIONS
This paper proposes using lean Manufacturing, ECRS, and TRIZ to reduce waste and increase production efficiency. The authors of this paper hope that implementing lean manufacturing with ECRS and TRIZ can contribute to the literature because of a more effective and efficient improvement solution. The implementation of Lean Manufacturing, together with ECRS and TRIZ, can respond to internal and external factors so that future development will positively impact increasing organizational effectiveness and efficiency. Further research needs to apply the principles of lean manufacturing, and its integration with the ECRS and TRIZ methods in company case studies to find out the benefits of these principles for problems in the field, how to meet/respond to company organizational needs with the proper method and its correct application better and continue the search for gaps or possibilities for development with other tools.
