With every new model introduced, management felt that the assembly line had to increase productivity and lower costs, usually resulting in changes to the assembly process.
Production of the subnotebook was scheduled to begin in 10 days. Initial production for the new model was to be at unitsper day, increasing to units per day the following week management Designing toshibas notebook computer line that eventually production would reach units per day.
Assembly lines at the plant normally were staffed by 10 operators who worked at a The line could accommodate up to 12 operators if there was a need. The line normally operated for 7.
It is possible to run one, two, or three hours of overtime, but employees The Assembly Line At the head of the assembly line, a computer displayed the daily production schedule, consisting of a list of model types and corresponding lot sizes scheduled to be assembled on the line.
A typical production schedule included seven or eight model types in lot sizes varying from 10 to units. The models were assembled sequentially: All the units of the first model were assembled, followed by all the units of the second, and so on. This computer screen also indicated how far along theassembly line was in completing its daily schedule, which served as a guide for the material handlers who supplied parts to the assembly lines.
The material supply system was very tightly coordinated and worked well. The assembly line consisted of a Workers stood shoulder to shoulder on one side of the conveyor and worked on the units as they moved by.
The supporter moved along the line, assisting workers who were falling behind and replacing workers who needed to take a break. Supporters also made decisions about what to do when problems were encountered during the assembly process such as a defective part.
Although the assembly line was designed for 10 workers, the number of workers could vary between 8 and These engineers design the line assuming that one notebook is assembled every two minutes by 10 line workers. In words, the following is a brief description of what each operator does: The first operator lays out the major components of a computer between two white lines on the conveyor.
The second operator enters the bar codes on those components into a centralized computer system by scanning the bar codes with a hand-held scanning wand. On a shelf above theconveyor, portable computers display the operations that are performed at each station. The next six steps of the assembly process involve a large number of simple operations performed by hand or with simple tools, such as electric screwdrivers.
Typical operations involve snapping connectors together or attaching parts with small screws. All tools are hung by a cable above the operators, within easy reach. Although the individual operations are simple, they require manual dexterity and speed.
The last two operations are the hardware and shock tests.
Toprepare for the hardware test, an operator inserts a memory card into the USB port containing software designed to test different components of the computer circuitry.
Because it takes nearly four minutes to load the testing software, the cycle time of this operation is longer than the other cycle times on the line.
To achieve a lower cycle time for the line, the hardware test is performed in parallel on three different units. The units remain on the moving conveyor, and the tests are staggered so that they can be performed by a single operator. The shock test the last operation on the assembly line tests the ability of the computer to withstand vibrations and minor impacts.
The computers are moved to a burn-in area after the assemblyline shock test. After burn-in, the computer is tested again, software is installed, and the finished notebook computer is packaged and placed on pallets.
Tweaking the Initial Assembly Line Design From past experience Toshihiro has found that the initial assemblyline design supplied by the engineers often needs to be tweaked.
Consider the following questions that Toshihiro is considering: What is the daily capacity of the assembly line designed by the engineers?
When it is running at maximum capacity, what is the efficiency of the line? How should the line be redesigned to operate at the target units per day, assuming that no overtime will be used?
What is the efficiency of your new design? What other issues might Toshihiro consider when bringing the new assembly line up to spe We guarantee that the paper will be delivered within the specified deadline.
