Look at the following OEE data for two sequential weeks. A single number that captures how well you are doing (OEE) and three numbers that capture the fundamental nature of your losses (Availability, Performance, and Quality). The water holding capacity of the soil is 13. IFS (Mains) AG 2010:20 marks 23- An irrigation stream of 24 litres per second is diverted to a check basin of size 10 m × 8 m. In the preferred calculation, you get the best of both worlds. conveyance efficiency of the canal, and then quantified the region-scale crop water footprint using the. (i) water conveyance efficiency, (ii) water application efficiency, (iii) water storage efficiency, and (iv) water distribution. This is the role of Availability, Performance, and Quality. The portion of water in a soil that can be readily absorbed by plant roots. We found conveyance efficiencies >90 for minor distributaries, 7089 for watercourses, and 75 for field ditches per kilometer. , decimal Available Water Capacity (AWC) Also known as available water (AW). Referring to the concept of antecedent precipitation index in hydrology, we defined the antecedent water conveyance index as a symbolic index of soil moisture. What your OEE score doesn’t provide is any insights as to the underlying causes of lost productivity. A Application Efficiency The ratio of the water that is stored in the root zone for later use by the plants to the total water applied. Other methods can be used for indirectly estimating channel flows, which require calculating flows using channel geometry and characteristics for example, channel dimensions, velocities, assumed roughness coefficient, and flow gradients can be used to calculate flow through the channel. In the calculation module of canal water conveyance loss, we improve the Kostiakov formula by considering the temporal variability and spatial variability of canal water conveyance loss. And it makes it easy to track improvements in that process over time. OEE scores provide very valuable insight – an accurate picture of how effectively your manufacturing process is running. 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). This is the “simplest” OEE calculation described earlier. While some power losses are inevitable as water power gets converted to electricity, they can be minimized with good design. The simple formula for this is: Net Power Gross Power x Efficiency. OEE = (Good Count × Ideal Cycle Time) / Planned Production Time Water use efficiency is defined as yield of marketable crop produced per unit of water used in evapotranspiration. is the measure of how much energy is actually converted.
