Abstract
Worldwide, industries are emphasizing the development of an agile system to sustain higher productivity, which can be applied to ensure improvements in all production conditions in industry 4.0. In the present scenario, several methods are used for improvements in production, such as value stream mapping, kaizen, just in time, Kanban, and total productive maintenance, etc., The objective of the present research article is to produce an agile system to sustain improvements in productivity through a methodology coupled with value stream mapping in industry 4.0. Value stream mapping is a lean-based method and is used for the maximization of productivity by the elimination of non-value-added activities. The proposed methodology has been validated by productivity enhancements achieved in a case study of the earthmoving machinery manufacturing sector. The study establishes that the proposed methodology would encourage industry personnel during decision-making processes, which would lead to improvements in production in industry 4.0.
Highlights
It has been found that the total uptime has been measured by computing the sum of the uptime of each operation, the total idle time has been measured by computing the sum of the cycle times of each operation, and the total turnaround time has been measured by computing the sum of the change times of the individual operations
After analysis of the proposed methodology coupled with value stream mapping (VSM), the results show that
In the was found that the total cycle time (TCT), total idle time (TIT), takt time (TT), TCOT, and as are in improved
Summary
Industry 4.0 production is highly affected by problems and challenges encountered on the shop floor. The problems may present themselves in several forms, including lack of resources, inefficient manpower, a poor working environment, outsourcing, machinery malfunction, and lack of production planning [1,2]. To dispense with these problems, various process optimization approaches have been implemented on the shop floors of many worldwide industries [3,4]. Lean manufacturing, kaizen, six sigma, total quality management, and lean six sigma have all been implemented as process optimization approaches for improving operational performance on the shop floor [4,5].
