BCY, CCY, LCY per hour. And, as described earlier, multiplying Good Count by Ideal Cycle Time results in Fully Productive Time (manufacturing only Good Parts, as fast as possible, with no Stop Time). What your OEE score doesn’t provide is any insights as to the underlying causes of lost productivity. Cycle Time for Transporting Material Example 1 • 175 tons of sand with a density of 1.75 ton/m3 must be transported 7 km using a 10m3 dump truck. It accounts for when the process is not running (both Unplanned Stops and Planned Stops). Formula: Planned Production Time − Stop Time, Example: 420 minutes − 47 minutes = 373 minutes. FOR TRUCK TYPE TRACTOR The usual tractor weight FOR 4-WHEEL TRACTOR Use weight on drivers shown on spec sheet or approximately 40% of vehicle gross weight FOR 2-WHEEL TRACTOR Use weight on drivers shown on spec sheet or approximately 50% of vehicle gross weight Surface Rubber tires Crawler tracks Dry, rough concrete 0.80-1.00 0.45 Dry, clay . Availability is the first of the three OEE factors to be calculated. • The haul speed is 30 km/h and return speed is 40 km/h . METHOD/MEDIA: This lesson will be presented by . Calculate the fleet size required to match loader's production. This operation is one of the key factor to reduce the cost of mineral production. 4. The Perfor-mance Handbook considers these factors in detail. And, it makes it easy to track improvements in that process over time. SBZ420 Qtys and Production calculations ST 2 - Earthmoving 1. Using the preferred OEE calculation (A x P x Q = OEE) makes it easier to take action against the underlying causes of lost productivity. 6/08 Petroleum Industry 5.2-7 Sample Calculation - Loading losses (L L) from a gasoline tank truck in dedicated vapor balance service and practicing vapor recovery would be calculated as follows, using Equation 1: Design basis - Cargo tank volume is 8000 gal OEE can also be calculated using the simple calculation. Calculate the fleet size required to match loader's production. A tank truck in dedicated vapor balance service (for the purpose of selecting a saturation factor) refers to the handling of one product, in which the vapors displaced during unloading are transported to the tank truck being emptied. 1. Performance takes into account anything that causes the manufacturing process to run at less than the maximum possible speed when it is running (including both Slow Cycles and Small Stops). F. H. Griffis. This paper presents a complete methodology that can be used to determine the number of trucks required per shovel TRUCKS AND HAULING EQUIPMENT ENCE 420 ©Assakkaf Slide No. Formula: (Ideal Cycle Time × Total Count) / Run Time, Example: (1.0 seconds × 19,271 widgets) / (373 minutes × 60 seconds) = 0.8611 (86.11%). The definition of a production system is thus based on four main elements: the input, the resources, the production process and the output. 3) There is less loss in production when one truck in a fleet breaks down. Most companies would not want to increase Availability by 5.0% at the expense of decreasing Quality by 4.5%.

Deep Learning with PyTorch teaches you to create deep learning and neural network systems with PyTorch. This practical book gets you to work right away building a tumor image classifier from scratch. Quality is the third of the three OEE factors to be calculated. In this study, OEE of shovels and trucks have been considered since they are the main equipments for the most of the Open Pit Mines. OEE can also be calculated using the simple calculation. Hence the calculation is: OEE = (Good Count × Ideal Cycle Time) / Planned Production Time. Struck, 14.7 cy Heaped 18.3 cy Net weight empty =36.860 lb ; speed 22 mph truck operatInG Mode Performance is the second of the three OEE factors to be calculated. 4) It is easier to balance the number of trucks with the output of the excavator, which will reduce the time lost by the trucks or the excavator.

The simplest way to calculate OEE is as the ratio of Fully Productive Time to Planned Production Time. This operation is one of the key factor to reduce the cost of mineral production. Optimizing Haul Fleet Size Using Queuing Theory. A "Production System" is a system whose function is to transform an input into a desired output by means of a process (the production process) and of resources.
