case study

• The Power King Manufacturing Company makes vacuum cleaners. Processing of production orders is as follows: At the end of each week, the production planning department prepares a master production schedule (MPS) that lists which vacuum cleaner models and quantities are to be produced during the next week. A production order preparation program accesses the MPS and the operations list (stored on a permanent disk file) to prepare production order for each vacuum cleaner model that is to be manufactured. Each new production order is added to the open production order master file stored on disk.

• Each day, parts department clerks review the open production orders and the MPS to determine which materials need to be released to production. All materials are bar-coded. Factory workers work individually at specially designed U-shaped work areas equipped with several machines to assist them in completely making a vacuum cleaner. Factory workers scan the bar-codes as they use materials. To operate a machine, the factory workers swipe their ID badge through a reader. This results in the system automatically collecting data identifying who produced each model of vacuum cleaner and how much time it took to make them. Once vacuum cleaner is finished, it is placed in a box. The last machine in each work cell prints a bar-code label that the worker affixes to the box. The packed and sealed vacuum cleaners are then sent to the warehouse.
