Effect of Maintenance Cost on Truck Performance & Reliability (CASE STUDY IN PETRO COST COMPANY)

Abstract

This research was conducted in “Petorcost Company for Engineering” to show the effect of maintenance cost on truck performance and reliability. The study was carried out using information and data gathered from different sources, hence treating them to find out the significant differences using statistical methods. The researcher used a sample of truck (3‐size) from equipment of road construction within the limits of the company’s equipment. Within the limit of sample, the results revealed significant differences: • The decision was made for maintenance program instead of renting equipment, which the primary study reflected (PWM‐R: 70,137 SDG, AWM‐R: 9,455 SDG/month, IRR: 10.84%, PBP: 7 months) the study applied in an ongoing project (Elkhuwei – Nahoud). Another study to confirm that was applied in Gazira project (will be executed soon) (Saving: 51.4%, PEP: 26 days of 83days). • There are significant differences in increasing the reliability and performance by applied the maintenance program (MTBF: 42HRS, Availability: 10%) Conclusively, the research came to the decision of using the owned equipment rather than rented equipment. The advantage is investment gain, conservation of equipment and giving the opportunity in the futuristic projects. The research recommended:‐ 1‐ The company system needs to be restructured in such a way that functions like operating/leasing of equipment to be under direct responsibility of the concerned equipment department and not the projects implementation department as in current practice. 2‐ Reforming the finance policy for the company business and concluding financing agreement with a reliable financial institution. 3‐ Using software in maintenance management such as “fleet maintenance software”.
