New Autonomous Vehicle Technologies Effect on Automotive Concept Design Stages

New road transportation systems solutions create significant changes in existing automotive manufacturing industry products and technologies, from design to use. The conveniences within the framework of new approaches brought by autonomous vehicle technologies primarily make individuals transition from driver duty to passenger and high-comfort alternative travel technologies. Therefore, the research: defining the path followed by the autonomous vehicle technologies, which lead to the development of the said new life model and automotive products within the future fiction, in the stages of designing new concept vehicles in practice or measuring the effect on the processes constitute important values for the future prediction of this sector. In addition, the research has focused on the effects of interdisciplinary studies at the automotive concept design stages, which are at the beginning of today’s lean and new product development process, where innovation goals or technologies emerge with more concrete needs. New autonomous vehicle technologies and the main purpose of revealing the interdisciplinary studies created by new disciplines in the current automotive concept design stages make significant contributions to the optimization of the lean product development process and value creation. For this reason, the automotive manufacturing industry, which is on the eve of a major transformation with the said new autonomous vehicle technologies;determining the needs or sustainable position in the flow of digital perception and orientation systems;determining value creation criteria related to the functioning of automotive concept design processes or new acceptance criteria through one-on-one interviews in the field;constitutes the focus of the research. The research has examined the new interdisciplinary studies and effects of new autonomous vehicle technologies in the automotive concept design phase, which is the first step of lean product development, with local and global automotive industry company comparisons in operation. Therefore, the differences and similarities between the concept design stages of global automotive companies that are both co-developers of new autonomous vehicle technologies and manufacturing automotive products and local automotive manufacturing companies that only assemble them determine the future competitive structuring of the industry.

Autonomous Vehicle Technologies Effects the Automotive Concept Design Stages with AHP Method

In the automotive concept design stages, functionally positioning the newly introduced autonomous technologies or remodelling the vehicle accordingly and evaluating the steps or determining the workload together with the collaboration intensity in the current flow is the initial step for the entire process efficiency. Therefore, the main purpose of the research is to reveal the effects of the autonomous technologies, which are newly included in the automotive concept design stages in automotive manufacturing industry companies that continue their lives under heavy competition conditions, according to the order of importance. The objective of this research is to both increase the efficiency of automotive concept design stages and to determine the measurement of the effects of new autonomous vehicle technologies in practice. Under the AHP method used in the research, the automotive concept design stages constitute the alternatives in the order of importance of the working structure, as well as the application variables of autonomous vehicle technologies, the criteria of the mathematical model. In addition, the research method modelled in the study, under the AHP mathematical model, reveals the performances or order of importance of the automotive concept design stages under autonomous technologies. Therefore, the resulting process performances constitute important inputs for efficiency and optimization studies under different research approaches. When the results of the study are examined, due to the high level of influence on the new vehicle concept design performance in automotive industry companies, the adaptation or application steps of autonomous vehicle technologies create new needs in the whole process. The determination of innovation creation clusters in the design process steps or the selection of the density of new technology adaptation in the stages and the order of importance provide a competitive advantage along with optimization in the basic functions of the automotive industry companies. However, the determination of new workload clusters in the mentioned automotive concept design process steps or the effect of autonomous technologies in the design stages, selection, transfer from theory to practice, multiple conflicting criteria and uncertain parameters create a very complex situation. For all these reasons, the Analytical Hierarchy Process (AHP), which is one of the widely used multi-criteria decision-making tools, is considered as a suitable approach for creating such order of importance and solving problems. In this study, an AHP mathematical model was created that determines the workload clusters created by autonomous vehicle technology applications that have just begun to guide the automotive concept design process, which is the main function of automotive manufacturing industry companies. Therefore, in line with the innovations, changes and adequacy criteria created by the current automotive concept design stages in the new autonomous vehicle technology adaptation, a stage order of importance has been selected.

Historical Development in the Automotive Industries of Argentina and Turkey

It is possible to say that the automotive industries of Argentina,Brazil,and Turkey are each developed as an assembly industry and show great similarities to each other in this context.Since the 1980s,the development direction of the world automotive industry has been trying to make the country’s investment environment attractive for foreign international companies to produce in their countries in all three countries.However,with the 1980s,their adaptation to the flexible production system and other new technologies being implemented in the Japanese automotive industry took time,meaning that the learning time took a long time,and local contribution rates fell.This has made the slow development mechanism that has been going on since the past work even slower,and they have suffered the punishment for not being able to develop technologies in all three countries by falling behind in the automotive industry.In the 2000s,with technological advances in electric vehicles,when the use of electric vehicles began to become widespread,we can say that all three countries began to experience a new adaptation problem in the automotive industry more severely.In Turkey,this problem was experienced with all its weight along with the other country;in 2006,the policy of attracting foreign investment to the automotive industry was partially abandoned and the approach to producing domestic cars began to be considered,and in 2011,a decision was made to produce domestic cars.As of December 2019,a prototype of the domestic car has been produced by the automobile initiative group of Turkey and work has started for mass production.Thus,the problem of adaptation to the production of electric vehicles was desired to be overcome by moving to a new stage in the path of technology development.The South Korean automotive industry used this approach in the 1980s and was successful and soon gained the ability to develop technology.In order to see the success of the application of this method in Turkey,it is thought that it is necessary to wait for the result of the domestic car project.

Historical Development in Brazil and Turkish Automotive Industry

It is possible to say that the automotive industries of Brazil and Turkey have developed as assembly industries and showed great similarities in this context.In the 1980s,in line with the development direction of the world’s automotive industry,Turkey tried to make the country’s investment environment attractive for foreign international companies to produce in their country.We can say that while Brazil created the state incentive system in order to attract foreign investments to its country since the 1950s,it tried to increase its dose with the 1990s.Although,like Turkey,Brazil has thought of producing local cars,the difference between Turkey and Brazil is that it has considered exporting and was able to export not only to South America,but also to African countries.Another difference of Brazil is that it has implemented incentive policies for the automotive sector and has been able to rearrange its incentive elements according to changing conditions.Turkey,on the other hand,has decided to return from the policy of attracting foreign investments to its country since 2006,and in 2011,it was decided to produce domestic automobiles.As of December 2019,a prototype of the domestic car was produced by Turkey’s Automobile Initiative Group and work for mass production began.Thus,the problem of adaptation to electric vehicle production was tried to be overcome by moving to a new phase in the way of technology development.This approach was used by the South Korean automotive industry in the 1980s and it was successful and technology development capability was gained in a short time.In order to see the success of the application of this method in Turkey,it is thought that it is necessary to wait for the result of the domestic automobile project.Brazil,on the other hand,was able to rank high in world automotive industry production with its sectoral incentive policies that can adapt to changing conditions and its structure that considers exports from the past,while Turkey lagged behind.

Historical Development in Mexico and Turkish Automotive Industries

It is possible to say that each of the Mexican and Turkish automotive industries is developed as an assembly industry and shows great similarities to each other within this framework.However,due to its geographical proximity,the role of US-based automotive companies in the formation of the Mexican automotive industry has become greater,while the Ford Motor company,which entered the US automotive industry in Turkey,was able to take part only with the initiatives of the Otosan company in the 1960s.Another feature of the 1960s is that there were efforts to manufacture domestic cars in Turkey.Since the 1980s,in line with the direction of development of the world automotive industry,Turkey has been trying to make the country’s investment environment attractive for foreign international companies to produce in their countries.In Mexico,even with the possibility of reaching new markets by providing 1990 regional agreements NAFTA ruling party of the Mexican automotive industry,we can say that U.S.firms were largely determined by the direction of development,Turkey’s automotive industry development direction of the company is determined by the first European,then we can say that companies are becoming more efficient in the Far East countries.On the other hand,the US Ford Motor company considered it sufficient to be involved in the Turkey directly.Turkey has decided to return from the policy of attracting foreign investments to its country since 2006,and in 2011 it was decided to produce domestic cars.As of December 2019,a prototype of a domestic car has been produced by the Automobile Enterprise Group of Turkey and work has begun on mass production.Thus,the problem of adaptation to the production of electric vehicles was decided to be overcome by moving to a new stage on the way to technology development.This approach was used by the South Korean automotive industry in the 1980s and was successful,and the ability to develop technology was acquired in a short time.In order to see the success of the application of this method in Turkey,it is thought that it is necessary to wait for the result of the domestic automobile project.Mexico’s policy of opening up more to foreign investments has been successful since the 1990s,and Mexico has become the most productive country in Latin America,surpassing Brazil in automotive industry production.

Path Dependent Historical Development at Turkish Automotive Industry

Turkey’s automotive industry has begun to occur at a much earlier date compared to other developing countries,through licensing agreements to establish automotive industrial facilities,by importing a kind of technology.Attempts have been made in order to produce the domestic automobile road providing sectoral developments could enter another technology pathway.Moreover,the inventor of a very early date in the Fordist production system,such as 1929 by Ford Motor Company with the license agreement,as if he could provide for setting up production facilities in Istanbul’s company,this bad experience has refrained for years from entering as a manufacturer Ford Motor Turkey market.Thus,while Turkey is an attractive market for car production,on the other hand,sufficient improvement over time in the production of trucks and other automotive products,such as buses has not been achieved.The 1929 experience seems to have been effective in terms of Turkey.Because,it was necessary to wait until 1971 for OYAK and TOFAŞto establish automobile assembly facility with license agreements.With the start of production of two automotive industry facilities,there has been a significant increase in sectoral production figures,but this increase trend has not been sufficiently supported by the government through the incentive system and in the late 1970s the production of the automotive industry has declined.For the first time in 1961,efforts were made to produce a completely domestic automobile,although the prototype of the revolutionary car was successfully produced,mass production could not be started.Subsequently,the production of the Anadol automobile for the second time was tried by means of technology transfer from multiple sources and the serial production of this automobile continued for a while.However,since fiber glass bodywork was used instead of hair bodywork and export opportunities could not be found,production was stopped completely in the end of 1980s.In the 1980s,automobile production continued in two assembly plants and product diversification was carried out to increase the production volume.In the 1990s,three new assembly facilities,Honda,Toyota and Hyundai,were established and the number of assembly production facilities in the country increased to five and technology loyalty based on technology imports continued.Until 2014,the automotive industry continued to consist of five automobile assembly plants and other automotive products assembly plants.In 2015,it was announced to the public that a new domestic car prototype was produced.It was announced that the project will start mass production in 2019.However,it was determined that the prototype would be re-manufactured at the end of 2019 by making changes in the project and that it would be possible to start mass production in 2022.Thus,it is understood that the efforts to start mass production since 2015 can be concluded in 2022,i.e.7 years after the first prototype was produced.It can 161produce prototypes in a short period of four months in Turkey in 1961,as evidenced by an indication of the dependency on a long time wasting which is not technology importation pathway,such as five years.How to break the path of devotion demonstrates that it is a difficult job.Path dependency is thought to result from the education system.

Historical Development in Brazil and Turkish Automotive Industry and Innovation Policies

It is possible to say that the automotive industries of Brazil and Turkey have developed as assembly industries and show great similarities in this context.In the 1980s,in line with the development direction of the world’s automotive industry,Turkey tried to make the country’s investment environment attractive for foreign international companies to produce in the country.We can say that while Brazil created the state incentive system in order to attract foreign investments to its country since the 1950s,it tried to increase its dose with the 1990s.Although,like Turkey,Brazil has thought of producing local cars,the difference between Turkey and Brazil is that it has considered exporting and was able to export not only to South America,but also to African countries.Another difference of Brazil is that it has implemented incentive policies for the automotive sector and has been able to rearrange its incentive elements according to changing conditions.Turkey,on the other hand,has decided to return from the policy of attracting foreign investments to its country since 2006,and in 2011,it decided to produce domestic automobiles.As of December 2019,a prototype of the domestic car was produced by Turkey’s Automobile Initiative Group and work for mass production began.Thus,the problem of adaptation to electric vehicle production was tried to be overcome by moving to a new phase in the way of technology development.This approach was used by the South Korean automotive industry in the 1980s and it was successful and technology development capability was gained in a short time.In order to see the success of the application of this method in Turkey,it is thought that it is necessary to wait for the result of the domestic automobile project.Brazil,on the other hand,was able to rank high in world automotive industry production with its sectoral incentive policies that can adapt to changing conditions and its structure that considers exports from the past,while Turkey lagged behind.
