Match factor for heterogeneous truck and loader fleets: International .Jun 25, 2008 . The mining and construction industries have used match factor for many decades as an indicator of productivity performance. The term match factor is usually defined as the ratio of truck arrival rate to loader service time. This ratio relies on the assumption that the truck and loader fleets are homogeneous.match factor mining,Match factor extensions - WikiFor the mining industry, the match factor ratio is an important indicator with a dual purpose: during the equipment selection phase, it can be used to determine an appro- priate fleet size such that the truck fleet productivity matches that of the loader fleet; when a fleet is selected, the match factor can be used to estimate the.

The match factor ratio is an important productivity index in the mining industry (see Figure 6). The match factor is simply the ratio of truck arrival rate to loader service time. Literature for the construction industry, in particular, uses match factor to determine a suitable truck fleet size. Smith et al. (2000).

Optimization of the fleet per shovel productivity in surface mining .

Oct 4, 2017 . A well-organized fleet management in surface mining is required in order to maximize truck per shovel Match Factors. The most common materials handling in surface mining is by truck and shovel combination. This operation is one of the key factor to reduce the cost of mineral production. This paper.

truck/shovel match factors (MF) and hence optimise fleet productivity. INTRODUCTION. The terms 'truck and shovel', 'shovel-truck-' or 'truck-shoveľ refers to a load-haul-dump mining system, involving any combination of loading units and trucks (Figure 1). Truck and shovel operations generally involve high costs. In surface.

Analysing equipment allocation through queuing theory and Monte .

Shovels and trucks are widely used in earth moving and surface mining operations as a materials handling system. Insufficient equipment allocation for a given fleet results in not achieving production targets, high production costs and opportunity costs associated with shovel idle times or truck queues. Match factor is.

Additionally, cost was not accounted for and the authors clearly indicated that in practice, the match factor is not all that useful, as mining operations may want a lower match number in order to minimize cost, whereas construction operations may want a higher match.
