Algorithmic Approach for Overhauling of Modern Bulldozers thorough Management Techniques (PERT/CPM)

Due to sudden breakdowns with farm machinery, the work in the field gets adversely affected. The knowledge of time and cost involved in a particular repair activity of farm machinery is essential to decide whether to continue the interrupted work and to assess whether or not it is possible to complete field operation within the stipulated time. PERT and CPM techniques have been applied to analyze the major overhauling of modern bulldozers. These techniques identified forty two subsystems or activities. The technique finalized 10 critical activities and expected completion of all events required 192 h with a variance of 8 h. The analysis revealed that the probability of completing the overhauling ranged from 0.299 to 0.331 for completion duration of 185 to 200 h, respectively.
