To critically analyse why "cell" based or "product" based layout being an essential component of JIT success.

Question

expected to critically analyse how these types of layouts contribute to successful JIT operations. Reference sources used and cited to developed the analysis is needed.

Answer 1

Just-in-time (JIT) Production Systems/Kanban and cellular manufacturing are closely related, as a cellular production layout is typically a prerequisite for achieving just-in-time production. JIT leverages the cellular manufacturing layout to significantly reduce inventory and work-in-process (WIP). JIT enables a company to produce the products its customers want, when they want them, in the amount they want. JIT techniques work to level production, spreading production evenly over time to foster a smooth flow between processes. Varying the mix of products produced on a single line, often referred to as shish-kebab production, provides an effective means for producing the desired production mix in a smooth manner. JIT frequently relies on the use of physical inventory control cues (or kanban) to signal the need to move or produce new raw materials or components from the previous process. A limited number of reusable containers are often used as kanban, assuring that only what is needed gets produced. Many companies implementing lean production systems are also requiring suppliers to deliver components using JIT. The company signals its suppliers, using computers or delivery of empty containers, to supply more of a particular component when they are needed. The end result is typically a significant reduction in waste associated with unnecessary inventory, WIP, and overproduction.
