Use of the AHP Methodology in Vehicle Design Process Dynamics: Determination of the Most Effective Concept Phases for the New Automotive Product

Abstract

The function of decision-making in the management of new product development and vehicle design activities is achieved by defining, constructing or evaluating the outcome-oriented, and most effective steps from the sub-steps that form this basic process. The choice of the sub-stages of the basic process or the decision of how to do a job gains importance in terms of the efficiency of the firm's activities. Therefore, the decision making function is one of the basic elements involved in the formation and development of the basic processes that can comply with the market dynamics of firms. With the new product being developed, the selection, the current editing or the evaluation of the steps that make up the vehicle design activities for the automotive industry companies that exist and compete in the market, bring about significant gains. In the manufacturing industry, the design of the vehicle determines the market spread, while the competitive conditions are driven by the new or improved product decision. In both cases, the automotive industry firms must know the stages of the most appropriate vehicle design in their own right, and the steps of forming new project dynamics must be devised in this direction. In this study, the result oriented activity of the current vehicle design phases used in the automotive industry companies is determined and the order of importance of the stages is listed. For this purpose, under the same conditions of competition (the same market, the same class vehicles develops and manufactures), 4 in the automotive firm administration, a total of 40 employees (4 × 10 process manager) with the vehicle design was evaluated by determining the effectiveness of the use of the stage. At this stage, analytic hierarchy methods applied to each of the phases are explored in practice in-How to cite this paper: Paker, F.A., Alppay, C. and Sertyeşilişik, B.

Determination AHP Analysis of the Virtual Stage-Gate Process in the Global Scale Automotive Design

“…In the field study findings, the design phase of the 38 stages, 6 in the first 14, and 8 in the remaining 24 steps were determined. Considering the development of the new vehicle, these design activities and design validation stages were evaluated with the AHP method [3]. In the new project formation, vehicle design activities, usage or idea sketch, 2D product sketch and vehicle technical aspects, concept development are formed in the initial stage of the product development process in automotive industry.…”

“…The new product, which has completed the stages of vehicle design, plays an active role in the growth and shrinkage or expansion of automotive companies in the new markets with the impression it gives to different users in different regional markets. Therefore, it is difficult to distinguish the contribution of vehicle design financially in the market share of the new product [1] [3]. The new vehicle design, starting with the decision to consolidate or privatize the opportunities in the markets that are targeted and expected to spread, extends to the control steps, including the verification of the product under these defined conditions.…”

“…Although design and design verification constitute two different product development titles, considering the stages of product development, a nested holistic structure is revealed. These process components were compared in the same region, in the same market, manufacturing with same class vehicle, dependent on global brand (MF) and independent local (BF) automotive companies were examined and the stages were compared [3]. In the study, six companies, which were evaluated under two groups in the automotive main industry, were visited in their factories and interviews were conducted.…”

New Autonomous Vehicle Technologies Effect on Automotive Concept Design Stages

“…The physical location of these autonomous technologies in practice creates new support technology requirements along with function needs. Today innovation has revealed the design of services along with products and technologies [1] [2] [3]. Therefore, autonomous vehicles, which have just started to be included in the automotive industry, have begun to materialize and become clear with their needs at the beginning of the lean product development process (automotive concept design stage), together with new technology installations.…”

Aplicación de Fuzzy-AHP y COPRAS en la selección de la mejor alternativa para el maquinado a alta velocidad de estructuras delgadas en aleaciones de aluminio Al 5083

“…En otro orden, (Paker et al, 2018), estudian la relevancia que tienen los procesos de manufactura y el diseño CAD enfocado en la industria del automovilismo y logran establecer, a través de métodos analíticos de jerarquía (AHP), los principales criterios que permitan alcanzar las mejores modificaciones de los diseños creados en cada uno de los proyectos para luego realizar su fabricación. (Bhowmik et al, 2019) revisa en los últimos 15 años varios de los métodos multicriterios para la toma de decisiones (MCDM), en los que se emplea la optimización de los procesos de manufactura.…”
