Automation is almost universally accepted as a good thing. The reasons for this acceptance are compelling. Productivity increases are an obvious advantage of automation, both in terms of production per hour and production per worker. Other advantages of the automation trend are decreased unit cost, increased safety, increased product quality, reduction of work in process, and greater predictability of the manufacturing function.
Operational Assessments
Published in James William Martin, Operational Excellence, 2021
Assessment preparation begins with forming a core planning team, conducting initial employee surveys, obtaining feedback from key stakeholders, and gathering operational and financial performance information. Stakeholder and contact lists are also created with an assessment plan. Integral to the assessment planning will be identifying where to create value stream maps to analyze the end to end supply chain or value flow maps of key processes. Data gathering helps focus an assessment on areas that have greater potential to create projects with high productivity opportunities.

The concept of lean manufacturing system was introduced by Toyota to minimize wastes from its processes and efficiently utilize the resources in their plants [129]. Through the elimination of wastes from industrial processes, the lean approach helps to improve efficiency, optimize cycle time, enhance productivity, reduce response times, reduce material costs, and facilitates high throughput. As wastes are reduced, the quality of the product improves, and the overall production time and product costs reduce. The primary aim of the lean approach is to focus on the needs of the customers. Fig. 7.9 shows the main aim behind lean production, different types of wastes in the factory, and outcomes of lean production. However, other existing approaches related to the various operation and controls in industrial sectors are considered from the perspective of tasks and production. Further, the lean approach is applicable across various industrial sectors, such as the manufacturing sector, inventory management, and healthcare industries.

Lean manufacturing is an established method utilised by industrial practitioners to increase productivity and work performance through the reduction and elimination of wastes and non-value-added (NVA) activities (dos Santos, Vieira, and Balbinotti 2015; Nunes 2015). Three types of potential deviations (3 M concept) that lean practitioners commonly analyse are Muda (NVA/Waste), Mura (Inconsistency), and Muri (overburden) in the system. Muda focuses on specific tasks and activities that do not add value to the production system and/or leading to waste; Mura is variability or irregularity introduced in the production whether in terms of quantity or quality; while Muri is about situation in which the production system, whether machines or workers are being overloaded beyond capacity or capability (Melo et al. 2020). Another established method that industrial practitioners used to improve productivity is through applications of occupational ergonomics. Ergonomics looks into optimising interactions between worker and the work system to protect worker’s well-being as well as improve productivity (Carayon, Sainfort, and Smith 1999; Sander and Mccormick 1993).

While human resources are scarce, competition is fierce, and customers are becoming more and more demanding; one of the practical solutions is the information technology application in the RL management. The application of new and innovative technological solutions has become imperative for firms to establish the RL. Technological advancements can increase productivity by reducing time, costs and errors. With the 4.0 revolution, there are various RL devotions activities such as green logistics, e-logistics, e-documents, etc. and application of blockchain technology, cloud computing, robotics or artificial intelligence to execute RL and waste product treatment activities. However, Vietnam’s electronic manufacturers and RL service providers currently still apply these technologies in low level, largely employing software package of warehouse management, vehicle locating technology and basic internet and email. In the digitisation trend, businesses need to adjust and encourage technology adoption to standardise operational procedures, enhance resources and costs-efficiency, supervise and increase management ability, increasing product/service quality, and intensify consumers’ loyalty and satisfaction. The research and development on RL for Vietnam are important to reduce the uncertainty and complexity of operational task. This study aims to identify the decisive RL practical activities in the electronic industry in Vietnam.

Productivity is a measure of efficiency a system that is computed as the ratio of output per period of time by the sum of the costs of various resources (workers, materials, and machines among others) (Sreekumar, Chhabra, and Yadav 2018). It is a key factor in the performance of a manufacturing company. Therefore, it is important to study the impact of implementing different technologies, developments, and improvements on the productivity of the factory. For this study, assembly time and worker costs are of particular interest. Furthermore, as the assembly scenarios require new automation systems, the investment and ROI of this acquisition also need to be considered. Ergonomics measures the physical impact on the worker by studying his body postures while performing production tasks. Performing tasks in non-ergonomic postures often results in decreased productivity and product quality (Zhao et al. 2016).
