In this blog post, we will explore how the future of industrial engineering can be expanded through user-centered design and system optimization.
If we look around us, we can see that the products and services we use in our daily lives are making our lives more convenient. For example, when shopping online, you can select the products you need or like and simply make a payment, and a delivery person will bring the package to your door. These things do not appear magically to consumers. Industrial engineering is the field of study that researches the complex processes behind this “magic” and learns how to provide products to consumers in a way that meets their needs.
Depending on the purpose of the product, the design process is the first step. Design is a task performed in any major. However, industrial engineering goes further by considering not only human psychology and behavior but also mental and physical limitations to design products centered on the user. Sometimes human behavior can be intriguing. For example, in the past, at the dormitory, the pedestrian path to Building 39 was clearly marked on the right, yet almost everyone walked on the left side. Therefore, products or services created without considering users will not be used by those users. By carefully observing human behavior, product design can become significantly more useful. For example, in the library, where students spend long hours sitting in one position, the design of chairs that minimize strain on the lower back is also crucial.
Those chairs were carefully selected by an industrial engineering professor. Therefore, when designing a product, it is important to conduct user-centered research in industrial engineering to ensure that users can use the product comfortably and easily. Another important aspect of industrial engineering is system analysis and optimization. For example, when designing a factory production line, various techniques are used to maximize the efficiency of each process.
By analyzing and improving bottlenecks in the production process, the overall production speed and efficiency can be increased. Such optimization contributes greatly to reducing production costs while maintaining product quality.
The most disappointing aspect of the process of designing a product and then manufacturing it is waste. Industrial engineering considers not only consumer needs but also the profits of manufacturers. The most important thing in the product production process is to minimize waste. Waste includes not only defects that must be discarded during manufacturing but also overproduction. This is because costs are incurred from storing products in warehouses for long periods and from unsold products. Most waste costs have a significant negative impact on profits. Therefore, industrial engineering also conducts demand forecasting research to reduce waste. By producing the optimal quantity based on reliable predictions, costs can be reduced and profits increased. In the aviation industry, demand forecasting has played a very important role. By accurately predicting how many business class passengers and how many economy class passengers will book seats on a flight, airlines can minimize losses from unsold seats or from selling seats at too low a price, thereby maximizing profits.
To gain consumer trust, product quality must be high. Therefore, it is necessary to carefully monitor for defects during manufacturing. Consistently inspecting products from design to manufacturing is also a role of industrial engineering. Industrial engineers use statistical analysis to measure standards within acceptable ranges while manufacturing products. In the past, product inspection was conducted after the product was completed, but now it is done during the manufacturing process. This allows for quick solutions to be found when problems arise. Otherwise, problems can accumulate and become complicated.
You need to understand what consumers want in order to introduce products or services to them. Industrial engineering has a tool for understanding consumers and users: data mining. Data mining involves organizing and analyzing data. In this era, there is an enormous amount of data, and it continues to grow. However, this data must be organized logically to become useful information. Why is it a tool? Because the information obtained through this process cannot be seen with the naked eye and often involves unusual phenomena. When consumers search for books they are interested in online, not only the books but also the consumer’s age, occupation, gender, and other information are collected. Through data mining, books that users may be interested in can be recommended. This weapon can be applied to many fields. It is also possible to analyze consumer purchasing and service usage patterns. When you go to a large supermarket, products are not just randomly placed. Instead, consumer purchasing patterns are analyzed, and products that sell well are placed together based on data analysis.
Additionally, industrial engineering places a strong emphasis on ergonomics (human factors engineering). It studies how work environments and tools affect users’ health and efficiency. For example, using ergonomically designed chairs and desks is important for people who work long hours at computers. Such research is essential for ensuring workers’ safety and health.
When we look at the products and services we use in our daily lives, we realize that they are no longer magic but the result of complex processes. Ultimately, industrial engineering is the field of study that researches products to meet consumer needs and integrates them into our lives. The diverse research and applications of industrial engineering make our lives more convenient and efficient, and in the future, even more innovative changes will occur.
