In recent years there has been an increasing interest in energy consumption in manufacturing systems due to the rising environmental awareness in society as well as the necessity of being cost-effective in the global competitive environment. Companies have to take measures to decrease their unnecessary energy consumption while maintaining their throughput. In this context lean manufacturing is regarded as one of the most significant management initiatives for energy management since it intensifies the effective utilization of resources via the identification and elimination of wastes. In this paper a holistic methodology which integrates Energy Value Stream Mapping experimental design and simulation is developed with the aim of analyzing and reducing the energy consumption within Lean Transformation. Moreover the effects of unevenness (mura) and overburden (muri) as root causes of waste (muda) on energy consumption has been addressed for the first time. The proposed methodology is applied to a real-life cable ladder manufacturing system and its feasibility is demonstrated. The results of the application showed that the adaptation of cellular manufacturing pull system and mistake-proofing yielded approximately 72.37% reduction in energy consumption.

Design of pull production control systems using axiomatic design principles
(Emerald Group Holdings Ltd., 2020) Ozgur Kabadurmus; Mehmet Bǔlent Durmuşoǧlu; Kabadurmus, Ozgur; Durmusoglu, Mehmet Bulent
Purpose: The purpose of this paper is to contribute to the lean manufacturing literature by providing a roadmap for pull production control system (PCS) implementation. Design/methodology/approach: Axiomatic Design (AD) methodology is used to develop the proposed pull PCS transformation roadmap. Findings: The proposed design methodology is validated in a real-life manufacturing system. The results show that the proposed methodology significantly reduces the design efforts. The methodology effectively helps to choose the most appropriate pull PCS and determine its operational settings with respect to the manufacturing system characteristics. Research limitations/implications: This study presents only one case study to test the proposed methodology. In future studies the validity of the proposed method can be further generalized in different manufacturing sectors by real-life implementations. Practical implications: In many real-life lean production projects companies do not know where to start or how to proceed which leads to repetitive design efforts and inefficient designs. The developed roadmap of this study minimizes incorrect or imperfect design trials and increases the success of pull production transformation projects. Originality/value: The implementation of pull PCS requires extensive design knowledge and expertise. Therefore many real-life applications fail due to costly and time-consuming trial-and-error-based design efforts. In the literature there is no comprehensive guideline or roadmap for pull PCS implementation. To address this issue this study provides a novel holistic roadmap to transform an existing push PCS to pull. The proposed methodology uses AD principles and combines fragmentary studies of the pull production literature. © 2021 Elsevier B.V. All rights reserved.
