Due to shortcomings existing in traditional overlapping model, a new extending activity overlapping model based on design structure matrix considering rework and iteration during activities execution is proposed in this article. Firstly, a tradional overlapping model presented by others is introduced. Sencondly, it is expanded to apply to more general situations using design structure matrix. Subsequently, an example deriving from a certain product development process is used in order to illustrate its effeciency and effectiness

Abstract This model estimates the probability of completing a product development process over time. The Design Structure Matrix (DSM) framework is used to capture the information dependencies between tasks using the concepts of Probability of Change and Impact. The model incorporates a stochastic element that represents the likelihood of changes resulting in task iterations. The model captures the dynamic behavior of a product development process formed by a combination of parallel, serial and coupled tasks. The model relaxes the assumption that coupled tasks take place in a complete parallel or serial iteration. It can be used to compare the development time of the project for different task sequences and overlapping degrees. This tool allows for identification of the leverage points in the system, providing information about the most effective way to reduce development time. This project was a joint effort with a Hewlett-Packard division, and the observations and practical application presented are based on this field experience.

A Company

Innovation is a major driving force for the economic growth and expansion of companies and the need to innovate has become clear by now. The quality of the decisions during the design phase of a product development process is strongly connected with the assessment of the product, process and organisational innovation dimensions. The developed methodology addresses these three axes, using 30 innovation attributes, in order to obtain a product innovation profile through an innovation survey. This way a range of industry standard Innovation scores called PIP-SCORES (Product Innovation Profile scores -or innovation benchmarks) have been established. So far more than 600 companies coming from a range of industrial sectors that include creative industries, electrical/electronic, fire and safety, footwear, plastics, ceramics and textiles, have participated in this survey and their innovation profiles have been included in the database. The proposed tool benchmarks the product innovation profile of a company with the corresponding innovation scores from companies coming from the same sector. Next, the tool utilises a Design Structure Matrix, for mapping the dependencies between the Innovation Attributes. Furthermore an Innovation Improvement Impact Value for each Attribute is introduced. In order to improve the innovative profile of a company, a considerable amount of resources is needed. Provided that resources are usually limited to most companies, an optimal improvement strategy, based on the Innovation Improvement Impact values is proposed. The proposed tool (I-DSM, Innovation - Design Structure Matrix) aims at improving the innovative performance of a company, by minimizing the product development cycle and by improving the performance of the product development process.

The Matrix

. The Design Structure Matrix (DSM) is becoming a popular representation and analysis tool for system and process modelling. A DSM displays the relationships between components of a system in a compact, visual, and analytically advantageous format which is a square matrix with identical row and column labels. The main goal in basic DSM analysis is to minimize feedbacks by restructuring or re-architecting the process, which is to say by resequencing the rows and columns of the matrix. This widely practiced initial step in analysis is called partitioning, block diagonalization, or block triangularization, and it involves an algorithm for getting the DSM in an upper-triangular form to the extent possible, with a minimum number of subdiagonal marks pulled as close to the diagonal as possible and grouped in blocks. As a consequence, we have to identify the activities which are coupled, the loops and reorganize the matrix in order to reduce the feedbacks. An application example has been presented to illustrate the power of DSM for product development process integration.

In this paper a simulation algorithm for concurrent product development process (CPDP) is presented based on Design Structure Matrix (DSM). An aggregate DSM is used to model the CPDP. To simulate the influence on the process of the time limit and the resource competition, the schedule and resource model are established. A method is also advanced to handle task delay. At last a case is used to validate the simulation algorithm and to show the influence on the process of task duration and resource.

Engineering change is an important and complex activity for manufacturing enterprises. In order to improve the efficiency of engineering change, designers should pay different attentions to different nodes of product development network. In that case, a method of classifying the nodes was proposed. First, we proposed a method to cluster the nodes based on design structure matrix; then, we analyzed the indexes for evaluating the importance of nodes and studied the method of classifying the nodes of product development network; finally, the experiment of managing a type of motorcycle engine was employed to validate our method and it showed the correctness of the proposed method.
