The maintenance and repair of equipment in a smart factory, along with equipment care, rely heavily on the stocking of spare parts.

The term Value Stream Mapping (VSM) originates from the 1999 bestseller *Learning to See* by Mike Rother and John Shook. The authors also coined the terms Value Stream Analysis (VSA) and Value Stream Design (VSD), and established a standardized set of symbols commonly used in value stream mapping.

Equipment failures are generally latent, and their progression adheres to the “normal‑abnormal‑failure” pattern.

Implementing predictive maintenance strategies is essential for building smart factories, as it slows the progression of minor early-stage faults into significant failures, thereby reducing equipment failure rates and optimizing production costs.

Conventional equipment data acquisition solutions often suffer from functional limitations and insufficient monitoring comprehensiveness.

JIT is the ideal state of production management, where parts are delivered in the required quantity, at the required time, and to the required location, without delays, without waiting, and without excess (original Japanese text: "Isn't it about providing what is needed, in the quantity needed, at the time needed?").

Addressing the challenges in spare parts management, the ALSI Smart Maintenance System incorporates a dedicated spare parts management module that enables real-time online inventory management.

Jidoka, a Japanese term coined by Toyota, refers to the ability of machines to make decisions like humans—sometimes called human-triggered automation. In a lean environment, Jidoka must be employed to identify and halt problems from escaping the process (eliminating waste).

Lean production originated from the Toyota Production System (TPS), which was pioneered by Taiichi Ohno at Toyota Motor Corporation in the 1950s. He theorized that anything beyond the minimum amount of materials, parts, equipment, and labor required to produce a given product constitutes waste, thereby increasing the overall cost of the system.

The ALSI Intelligent Device Management Solution not only assists enterprises in bridging information flow gaps during the construction of smart factories, but also facilitates the optimization of collaborative production processes.
