Better cars for less
Article Abstract:
Robots and other automation techniques are not the only way to improve efficiency and productivity. Better organized work flow, better timing, and careful choice of employees to avoid adversarial situations are all part of the equation. The search for efficiency has to go beyond the assembly line because the labor cost on an assembly line is typically only 5 to 10 percent of total. Materials account typically for 50 to 60 percent of a car's total cost. Cars can be redesigned to be assembled more efficiently, and changes in the way components and the final product are assembled can reduce work in-process inventory team and keep rein on defects. New means of assembly also take advantage of them spirit, with workers doing multiple and changing tasks. Another tool is Manufacturing Automation Protocol (MAP), a computer network enforcing a common protocol over a variety of automated equipment. GM is using MAP for making trucks in several manufacturing locations.

How and when to make tradeoffs
Article Abstract:
Optimal designs do not have parts that: cost more, increases weight, requires more space, and takes more time to assemble without providing needed capabilities. Design time is viewed as another "part" to be reduced, making the optimal design the lowest-priced. Two basic rules to apply are: use standard parts when possible; and optimize the element that limits the product's capability. Relying on existing technology is a cost-effective optimizing technique, and standard parts are continually being upgraded.
