INTRODUCTION TO PLANNING AND INTEGRATION OF PRODUCT DEVELOPMENT

INTRODUCTION

Overview

Today’s market is characterized by keen international competition, increasingly complex products, and an extremely high innovation dynamic. Parallel to the shortening of innovation cycles, the life cycles of products and the time until investments pay off are decreasing.

Thus, time is presently the most challenging parameter. Fast, successful positioning of new prod- ucts on the market has become vital for a company, and the development of innovative products needs to be accelerated. The production of prototypes is significant for a rapid product development (RPD) process.

One feature of this process is the coordination of work tasks within the distributed teams. It will become increasingly important to bring together the different experts. Effective and efficient project management is the basis for the way a team functions. The early integration of different experts serves as a means to develop innovative products. This is also an important factor concerning costs because the main part of the end costs are determined in the early phases of product development. To facilitate the integration of different experts and enhance the efficiency of the iterative phases, prototypes are used as cost-efficient visual models.

New RP Technologies

Generative prototyping technologies, such as stereolithography (STL), reduce prototyping lead times from a few hours to up to three months, depending on the quality required. These prototypes can serve as visual models or as models for follow-up technologies such as casting.

Planning and Integration of Product Development-0017

New, powerful CAD technologies make it possible to check design varieties in real time employ- ing virtual reality tools. The use of virtual prototypes, especially in the early phases of product development, enables time- and cost-efficient decision making.

Communication Technologies

ATM (asynchronous transfer mode) networks (Ginsburg 1996) and gigabit ethernet networking (Quinn and Russell 1999) enable a quick and safe exchange of relevant data and thus support the development process tremendously. The Internet provides access to relevant information from all over the world in no time, such as via the World Wide Web or e-mail messages. Communication and cooperation are further supported by CSCW tools (Bullinger et al. 1996) like videoconferencing and e-mail. The distributed teams need technical support for the development of a product to enable synchronous and asynchronous interactions. Furthermore, the Internet provides a platform for the interaction of distributed experts within the framework of virtual enterprises. The technologies used support the consciousness of working temporarily in a network, which includes, for example, the possibility of accessing the same files. All these new technologies have been the focus of scientific and industrial interest for quite a while now. However, the understanding how these new technologies can be integrated into one continuous process chain has been neglected. Combining these technologies effectively enables the product-development process to be reduced decisively. Rapid product devel- opment is a holistic concept that describes a rapid development process achieved mainly by combining and integrating innovative prototyping technologies as well as modern CSCW (computer-supported cooperative work) tools.

Objectives of the new concept of RPD are to:

• Shorten the time-to-market (from the first sketch to market launch)

• Develop innovative products by optimizing the factors of time, cost, and quality

• Increase quality from the point of view of the principle of completeness

DUALITY THEORY:THE ESSENCE OF DUALITY THEORY

THE ESSENCE OF DUALITY THEORY Given our standard form for the primal problem at the left (perhaps after conversion from another form), its dual problem has the form shown to the right. Thus, with the primal problem in maximizatio n form, the dual problem is in minimization form instead. Furthermore, the dual problem uses exactly the same pa r amete r s as the primal problem, but in different locations, as summarized below. 1. The coefficients in the objective function of the primal problem are the right-hand sides of the functional constraints in the dual problem. 2. The right-hand sides of the functional constraints in the primal problem are the coef- ficients in the objective function of the dual problem. 3. The coefficients of a variable in the functional constraints of the primal problem are the coefficients in a functional constraint of the dual problem. To highlight the comparison, now look at these same two problems in matrix notation (as introduced at the beginn...

NETWORK OPTIMIZATION MODELS:THE MINIMUM SPANNING TREE PROBLEM

THE MINIMUM SPANNING TREE PROBLEM The minimum spanning tree problem bears some similarities to the main version of the shortest-path problem presented in the preceding section. In both cases, an undi r ecte d and connected network is being considered, where the given information includes some mea- sure of the positive length (distance, cost, time, etc.) associated with each link. Both problems also involve choosing a set of links that have the shortest total length among all sets of links that satisfy a certain property. For the shortest-path problem, this property is that the chosen links must provide a path between the origin and the destination. For the minimum spanning tree problem, the required property is that the chosen links must provide a path between ea c h pair of nodes. The minimum spanning tree problem can be summarized as follows: 1. You are given the nodes of a network but not the links. Instead, you are given the po- tential links and the positive length for each ...

INTEGER PROGRAMMING:THE BRANCH-AND-CUT APPROACH TO SOLVING BIP PROBLEMS

By -
TH E BRANCH-AND-CUT APPROACH TO SOLVING BIP PROBLEMS Integer programming has been an especially exciting area of OR since the mid-1980s be- cause of the dramatic progress being made in its solution methodology. Background To place this progress into perspective, consider the historical background. One big break- through had come in the 1960s and early 1970s with the development and refinement of the branch-and-bound approach. But then the state of the art seemed to hit a plateau. Rel- atively small problems (well under 100 variables) could be solved very efficiently, but even a modest increase in problem size might cause an explosion in computation time be- yond feasible limits. Little progress was being made in overcoming this exponential growth in computation time as the problem size was increased. Many important problems arising in practice could not be solved. Then came the next breakthrough in the mid-1980s, with the introduction of the b r an c h- and-cu t approach to sol...
