And lists of timely job, you can work days, days of operation, the actual operation and meteorological factors such as the number of days. (4) determine the activities of variables and number of people, machines and animals: activities of the model structure optimization variables. People, machines, animals, \95. (2) Weather Coefficient, Ri = number of operational days / fitness during the days = 0.8 - 0.9, weather operating items, weather factor Ri = 1. (3) to determine the agricultural job productivity. ① human and livestock productivity, job commitment by animal-drawn plowing fields plowing 2 acres per day, except upland crop stubble of a labor than 3 acres per day, paddy harrow rake per day 2 acres of paddy fields, upland planting each half-day labor, etc. can be planted 15 acres. ② tractor unit operating hours of productivity of various projects in different job productivity is also different. After detailed calculations (calculation of hours of productivity and calculate the first day productivity.) lists the optimization model with Tonghua City Agricultural Statistics Table. For example: large tractor 8 acres of fields and send manure / day. medium-sized tractors 6 acres of field to send manure / day,<a href="http://www.uggboots-jp.org" target="_blank" class="postlink">UGG ブーツ</a>, to send a small tractor manure 3 acres of field / day. large tractor plowing 50 acres of upland / day, medium-sized tractors plowing upland 30 acres / day,<a href="http://www.mbtshoesitalia.com" target="_blank" class="postlink">mbt shoes italia</a>, small tractors plowing l0 acres of upland / day. (4) the calculation of the objective function objective function calculation unit operating hours, including variable costs (variable costs standard acres, machinery maintenance and overhaul of depreciation), total on variable costs, respectively, the mathematical formulas and calculations. 4. model constraints and the superscript function to determine the amount of constraint to establish operations, animal power constraints, labor constraints, constraints in the mathematical model of mechanical distribution and calculated to determine the objective function. 5. Mathematical Model and Solution to rely on the above analysis and calculation,<a href="http://www.toryburchshoesoutlet.net" target="_blank" class="postlink">tory burch outlet</a>, are listed in Tonghua City of agricultural people, machines, animals optimization model is equipped with tables. 1995,2000,2020 by the table lists the linear programming model year, after solving the machine thirty of the reporting period can be obtained by the optimization program. 6. optimization program results and analysis In order to evaluate the reasonableness of agricultural equipment,<a href="http://www.tiffanysdeutschland.com" target="_blank" class="postlink">tiffany deutschland</a>, we will be reality system were compared with the optimization scheme. contrast the following table: real contrast to the situation and optimization system real bad index screen model system unification (1990) l9952 Shuai 02020 drag large 822l750217S2250 pull d | 209717361 52500 stare SMALL 10957144741373711369 29769144351370012598 producing of agricultural machines 4675906287427R2195935649 Total Power (kW) livestock 62477l6599408l18 ∞ 955560 12739216762199087314 Taiwan dollars per kilowatt of the burden of arable land (mu) 6. 866.29S4.08 machine machine machine turned 66879525472o0234l0021602 mechanical rake 7000001260 ∞ 0127000l430000 of sowing machines 1O5 ∞ 22000002220000220000 plug process equipment 410 600 000 100 1 Shuai Shuai Shuai 0o1200000 degree machine cultivator 1656002200 21000002160000 65200100000200000250 ∞ 0 machine plant machine expense of livestock 1:157:1:44 : 1} 57:1:74: with more than 3.61.161.160.58 can be seen from the comparison table: (1) 1995, 2020, the burden of power per kilowatt of cultivated land are lower than reality system. people , machines, animals with a significantly better than the real system. (2) model of labor in the number of animal deposited far below the actual system. Because the increase in machinery, saving 50% of the workforce can be engaged in other industries. reduced by 80 % of the livestock. (3) from all ten times the amount of investment of view, the program is feasible. Based on the optimization program can list running machinery each period and the amount of investment.
