Help me rewrite the following passage:
4.1Adopting One-piece Flow Line
One-piece flow is a better way to save waiting time and avoid overproduction than batch production. In our class, the professor also invited students to conduct simulation. The three students first simulated batch production and then simulated one-piece flow. Under the same output, we could intuitively find that one-piece flow worked more efficiently. With the help of one-piece flow mode, KE company can reduce inventory cost and lead time, improve product quality, and the whole productivity can be improved. Besides, workers have less waiting time, which is also beneficial to staff management and work efficiency improvement.
4.2Visual Management-Kanban
In manufacturing industry, kanban always means kanban cards, visible cards. The categories of kanban which is commonly used are production kanban and withdrawal kanban. 
Using the Kanban system in the production system of KE company, it is possible to immediately comprehend the raw material demand objective for each process as well as the present production status of each process. It is possible to combine effective handoff between the front and rear operations with continuous flow. Each oil filter will be produced at a lower volume, preventing unnecessary movement and cutting down on work-in-process time.
4.3Overall Equipment Effectiveness (OEE) Management
In the industrial process, OEE is an indicator to quantifies a production system’s rate of efficiency which combines 3 factors: availability (breakdowns & setups/changeover), performance (idling & reduced speed), and quality (scrap & rework). OEE is widely used for lean improvement, as the given case KE company mentioned before, KE company can find the root source of mistakes and inefficiencies, and then quantify the degree of inefficiencies to explore severity with the help of calculating OEE indicator.
4.45S Management
According to Korkut et al. (2009), 5S comes from Japan, which was first used in a Japanese manufacturing company. 5S stands for Sort, Straighten, Sweep, Standardize, and Sustain, which is a key in lean production management. Through 5S, workers are provided with a clean and tidy place, and wastes can be easily noticed. Narasimhan (2009) stated that the improvement of companies can be seen obviously after using 5S model. Besides, KE company can quickly improve the organizational atmosphere and mobilize the enthusiasm of employees. As the quality of life improves, so does productivity and efficiency. In a long run, 5S management makes KE competitive and promotes its economic development.
4.5Jidoka and Poka Yoke Management
In KE company, the defect rate in milling process is 18%, which is relatively high and leads to lots of time waste, material waste, and labor waste. Jidoka means autonomation, which refers to ‘automation with a human touch’. With Jidoka, one worker can operate multiple machines, increasing productivity dramatically. Besides, Jidoka can recognize the mistakes or abnormality in the machine, and then stop the machine automatically, which helps workers find and stop the mistakes in time, and reduce unnecessary loss of manpower and material. Poka Yoka aims to eliminate product defect by preventing, correcting errors, and drawing attention to human. There are two kinds of Poka Yoka: control Poka Yoka is considered in the product design phase to prevent mistakes, and warning Poka Yoka aims to alert workers when they are about to make mistakes with color and sound. With the help of Jidoka and Poka Yoka, KE company can decrease the defect rate during the processes, find and solve problems in time, and increase productivity efficiency.
