Short Answer

Expert verified

Answer

JIT stands for Just in Time, whereas MRP is for Manufacturing Resource Planning.

MRP is a resource planning system that is time-phased and focuses on the future, whereas JIT does not.

Synchronous manufacturing (SM) is a lesser-known manufacturing management concept that considers an organization's resources and operations as parts of an interconnected network and controls them to improve the overall system's performance.

Step by step solution

Material requirement planning (MRP) is the backward scheduling of resources from the master schedule production Performa
