The ABCs of Just-In-Sequence Manufacturing

Just in Sequence (JIS) manufacturing is essentially a precision version of just-in-time (JIT) manufacturing. It takes the core principle of receiving materials exactly when needed and adds another layer, ensuring they arrive in the exact order they will be used for assembly.

The Core Concept:

Imagine an assembly line where parts magically appear exactly when and in the exact order they are needed. That is the essence of JIS. It takes the "just-in-time" (JIT) principle of receiving materials at the precise moment and adds a very important element: sequencing. JIS eliminates wasted time searching and minimizing storage needs.

What are the Benefits in using JIS?

1. Increased Efficiency : The workers just grab the next part in the sequence, eliminating wasted time for searching the components.
2. Reduced Waste : Less Storage space is needed, and there is a lower risk of parts becoming obsolete.
3. Improved Quality : A streamlined process can minimize errors during assembly.

As a coin has two sides there are also challenges in implementing the JIS manufacturing system. They are,

1. Communication should be strong with suppliers to ensure precisely timed and sequenced deliveries. If there is a slight miscommunication the entire assembly line might come to a halt.
2. Delays from suppliers or production line issues can throw the whole process off.
3. There is no space for flexibility. This system best works for high volume production of similar products.

Applications:

JIS is particularly common in the automotive industry, where car parts are delivered directly to the assembly line in the order they will be used on a specific vehicle. Sometimes it is also called as In-Line Vehicle Sequencing (ILVS).

To implement a successful JIS manufacturing system the organisation must set up a strong information technology systems as they are crucial for real time communication and production scheduling and also careful planning and a high degree of coordination are essential for smooth implementation.

All things Considered, JIS manufacturing can be a powerful tool for streamlining production, but requires a well-oiled system to function effectively. JIS manufacturing can be a powerful tool for streamlining production, but requires a well-oiled system to function effectively.
