Factors.
Figure 4.4.1a(i) showed the main effect of the measurable environmental factors on the maintenance costs of Nissan Urvan vehicles over the given periods. From the plot, it is observed that the maintenance cost increases as the (km) increases, but at the distance of 11852(km),there is a decrease in maintenance cost a pointer to the fact that there is a possibility of having a less maintenance by virtue of good road and better management. Precipitation, Temperature and Relative Humidity had the highest effect at 1696.4, 28.40 and 129.68 respectively while the lowest environmental influences were at 1620.0, 29.20 and 156.90 respectively on maintenance costs of Nissan Urvan vehicles. The plots also showed that at the maximum environmental effect, the company would spend more on the maintenance of its vehicles and less income would be generated.

Figure 4.4.1a(ii)established the effect of the measurable environmental factors on the maintenance cost of Sienna vehicles. The outcome showed that precipitation, temperature and relative humidity had the highest environmental effect at 1695.0, 28.40 and 129.70 respectively while the lowest environmental influences were at 1620.0, 29.20 and 156.90 respectively for the maintenance cost of Sienna vehicles.The outcome also showed that at the maximum environmental effect, the company would spend more on the maintenance of its vehicles and less income would be generated. On the other hand, at the minimum environmental effect, the company would spend less on the maintainability of its vehicles, thereby making more profit.
