Abstract:
To evaluate risks in product development and improve product
development process, a logical iteration struc- ture based method
for process simulation is proposed. A logical iteration structure
net based process model is defined and it is used to extend design
structure matrix based process model used in traditional simulation
method. Effects of logical relationships among iterations are
considered in new model so that errors caused by neglecting logical
relationships can be avoided. Algorithm and inputs of process
simulation system based on new model are given. Then logical
iteration structure based process simulation system is developed and
motocycle brake development process is applied as an example. New
simulation method extend traditional process simulation model and
reduce errors in traditional process simulation method. It can
improve accuracy of analysis and estimation of product development
process and improve efficiency of product development.
Key words: Product development process management
