Blog article "Advantages and Disadvantages of Work Work Sampling (Operational Analysis)"

NX総合研究所 NX総合研究所
This article provides a detailed explanation of the purpose and implementation methods of work sampling (operational analysis) in IE (Industrial Engineering) techniques used in the manufacturing and logistics industries. While work sampling with an observer allows for highly accurate operational analysis, it also requires significant preparation and effort, presenting both advantages and disadvantages. We will introduce methods to address the disadvantages through the promotion of digital transformation (DX).

Hyper CLT flooring panel

Added a glossary to the website to make technical terms easier to understand.

  • NEW
  • PRODUCT

We have added a new **"Glossary"** to the Hyper CLT sheet website. In the civil engineering and construction industries, there are many specialized terms such as "CLT," "NETIS," "temporary roads," and "wooden lightweight sheets." Therefore, we have introduced related terms in an easy-to-understand manner so that those who are encountering Hyper CLT sheets for the first time can understand the products and technologies. Hyper CLT sheets are wooden lightweight sheets for civil engineering that utilize wood CLT and are registered under the Ministry of Land, Infrastructure, Transport and Tourism's NETIS technology as **"TH-250021-A."** We hope that by not only conveying the features of the product but also sharing the underlying technologies and terminology, users will feel a closer connection to Hyper CLT sheets. We will continue to enhance our website and provide clear information related to wood, NETIS, civil engineering, and CLT.

Hyper CLT flooring panel

On September 15, we issued a press release for the hyper CLT flooring.

  • NEW
  • PRODUCT

On September 15, 2026, we issued a press release regarding the wooden lightweight sheet "Hyper CLT Sheet." The Hyper CLT Sheet is a civil engineering sheet that utilizes CLT (Cross-Laminated Timber) stacked in an orthogonal direction. It can be used in various locations such as temporary roads, access routes, heavy machinery work yards, and material storage areas. The 5×10 version weighs approximately 230 kg, making it relatively lightweight and easy to install, remove, and relocate. Additionally, it offers environmental benefits such as reducing glare and metallic sounds typical of wood, as well as CO2 fixation. Furthermore, it can be proposed for the use of new technologies in public works as a **registered technology with the Ministry of Land, Infrastructure, Transport and Tourism "TH-250021-A."** Through this press release, we aim to expand the new wooden lightweight sheet that combines wood, NETIS, civil engineering, and CLT to more construction sites.

Casting sand mold 3D printer prototype production

  • NEW
  • COMPANY

● The production time for cast prototypes can be shortened! Since model making is not required, the production time for prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or varying dimensions, can be molded at the same time in one molding process. This allows for the verification of multiple types in a short period.
