Computer-aided Work System (caws) Analysis And Design

As the humans step into 21st century, accompanying with the development of computers and internet technique, the information level of domestic manufacturing quickly increased, it has been the effective way to make the manufacturing competed, there is also a prodigious development in enterprise information software system these years, such as CAD, CAPP and ERP; however, the weak accuracy of enterprise basic data is not comfortable with the rapid development of these information software, it has greatly restricted further development of enterprise information system. Therefore, although many corporations spend a lot on introducing the ERP, it has not got the expectable result.Based on the situation above, this passage indicates the Computer aided work study system (CAWS), it aims to explore a computer-assistant technique base for enterprise in setting down the scientific busywork method and credible man-hour ration, which makes the enterprise busywork method establishing in scientification and standardization, the basic data like man-hour ration is got in automatization. It greatly increased the accuracy and timing of enterprise basic data, especially the effective integration with CAD/CAM/CAPP/PDM, which will benefit to accelerate the process of enterprise information in our country.There are five parts of the paper:The first part states the investigation meaning of the topic, introduces the main content of task and its application status home and abroad, indicates some theory technique correlative with the topic, such as computer-assistant technique and group technique. It also explains the problem existed in task.The second part investigates the general situation and character of software task abroad and indicates problem accrued, the design of this system is based on that and the collectivity function of system and subsystem function are described. The integration model of CAWS system and other system are discussed here.The third part introduces Object Oriented basic modeling language--...
