Brisa: Virtuoso of Supply Chain Risk Management
Published in Çağrı Haksöz, Risk Intelligent Supply Chains, 2018
Brisa is the leader in the Turkish market and the seventh largest tire producer in Europe. In the 1960s, Goodyear and Pirelli were manufacturing pioneers in Turkey. In 1974, Lassa Tire Manufacturing and Trading Inc. was established. A partnership agreement with Bridgestone was signed in 1988, changing the company’s name to Brisa Bridgestone Sabancı Tire Manufacturing and Inc. In 1996, Brisa won a number of awards, including the European Quality Award (EFQM), Environment Award (by the İstanbul Chamber of Industry), and Best Performing Supplier Award (Automotive Industrialist Association). Moreover, in 1999, Toyota awarded Brisa the “Top Scoring Supplier Award.” This success has continued to today with more awards and honors, including Bridgestone as sole official tire supplier of Formula 1.6 Today, Brisa exports its products under Bridgestone and Lassa brands to more than fifty countries that are mostly European.7 As of February 2011, its market capitalization was US$696 million.8

A tire manufacturing company rejects tires if the median diameter of a tire is not equal to 10 inches. Suppose a quality controller randomly selects a sample of 30 tires to test whether the median diameter is different from 10 inches. Does the following data help the quality controller to confirm his prior assumption using the level of significance α = 0.01?

The pyrolysis of the truck tire powder showed significant yields of pyrolytic vapors (62 wt%). The carbonization efficiency (CB yield) is practically insensitive to operating conditions (38 wt%). It represents the mass of the carbon black and metals used in the tire manufacturing process.

The overall variation trend of distribution of gaseous products was that all gas contents increased as the residence time extended. Thereinto, H2, CO and CO2 showed small changes, whereas light hydrocarbons were very sensitive to residence time. Generally, dehydrogenation, dealkylation and decarboxylation were three predominant factors affecting the content of gaseous products, generating H2, COx and CH4, respectively. It can be seen from Figure 7 that the extension of residence time greatly promoted dealkylation, leading to a significant increase of CH4. Meanwhile, C2, C3 and C4 also showed an apparent growing trend, implying deeper cracking of long-chain alkanes and alkenes. The phenomenon was consistent with the results obtained in the analysis of liquid products. To further study the compositions of C2–C4, each group was divided into alkanes and alkenes. As shown in Figure 7, the red and blue bar represent alkanes and alkenes, respectively. As can be seen from the coloured bar graph, the content of alkenes was much more than alkanes’, especially in the C4 group, which was in connection with the compositions of rubber. The rubber in the tire manufacturing process included mainly natural rubber, butyl rubber and styrene–butadiene rubber [3], which contained a lot of unsaturated bonds. Deep cracking of these rubbers formed gaseous C2–C4 alkanes and alkenes.
