The Relationship

The appropriate iteration process model is the basis for managing and optimizing the product development process. In this article, we attempt to introduce the concept of process effectiveness and process value. The relationship between rework probability and process effectiveness is discussed. The evolution function of process effectiveness is proposed to drive the overlapped iteration process of multi-coupled activities. The evolution process with input information update is studied, and a simulation model is presented to obtain the accurate iteration process of development. It is useful to analyze the risks during development, and has good flexibility and versatility. The calculation method of process value for overlapped iteration process is given, and an optimization model for product development process is provided. The model is used to improve the development process of the stamping die of a car roof. With the model, we can get a suitable overlapping rate of multi-coupled activities to improve development performance.

Set Up

Based on studying design behavior and design thinking, a design behavior model which dealt with person, QCTS (quality, cost, time and service), process and environment in product design was set up. The key factors and connotation of product design were discussed based on the model. An expanded design environments model and a systematic design process model were set up. The results show that person, product, process and environment are key factors of product design; in design, the person is body of thinking, QCTS is goal, the process is behavior formula, and the environment is restraint; the product design is a process driven by customers’ requirements in which the knowledge is used and is materialized based on brain, and abstract or detail concepts are changed to a physical assembly or a product step by step.
