1. Technological advances in production management like FMS, CIM, robotics, and CAD have increased flexibility, agility, and responsiveness while reducing changeover times, waste, and promoting cleaner production methods.
2. Robots can work continuously without breaks, ensuring consistency, but they are mechanical devices blind to people and environments and unable to detect their own deterioration.
3. MRP's approach of batch production poses capacity and idle time problems for GT cells that rely on even flow, and reconciling MRP and GT logics is challenging when integrating them.
