A work centre is interested in limiting work-in-process by not allowing production to start again until the current batch is finished. The best solution most likely involves

A) MRP.
B) ConWIP cards.
C) Gantt Charts.
D) Johnson's rule.
E) Loading.

ConWIP (Constant Work in Progress) cards are a tool used in the pull production system, where production is triggered by actual customer demand. ConWIP cards limit the amount of work in progress, as each card represents a specific quantity of work to be completed before the next batch can start. This helps to prevent overproduction, minimize lead times, and improve flow efficiency. Therefore, ConWIP cards would be the best solution for limiting work-in-process and preventing production from starting until the current batch is finished.
