Operaton Cost Model for Feed Production

배합사료생산(配合飼料生産)에 소요(所要)되는 운전비용(運轉費用)을 추정(推定)하기 위(爲)하여 소요(所要)에너지, 소요노동력(所要努動力), 유지(維持) 및 수리비(修理費)를 분석(分析)하여 공장규모(工場規模) 및 사료생산종류(飼料生産種類)에 따른 수학적모형을 개발(開發)하였다. 에너지비용(費用)은 전기비용(電氣費用)과 연료비용(燃料費用)으로 구분(區分)하였으며 소요노동력(所要努動力)은 생산노동력(生産努動力), 관리자노동력(管理者努動力) 그리고 유지(維持) 및 수리노동력(修理努動力)으로 구분(區分)하였다.

For the purpose of estimating the operating cost for feed production, energy consumption, labor requirement, maintenance cost, and supplies and miscellaneous costs are analyzed and developed as mathematical models. Mathematical model for energy usage Consists of electrical energy, boiler fuel energy and vehicle fuel energy. The mathematil model for electrical energy usage for the swine and poultry feed mill and the complete pelleted feed mill are developed, based on the general model mill and the computer program for its design developed in Kansas State University (Park, 1982). Also, the boiler fuel energy consumption model and the vehicle fuel energy consumption model are developed by analyzing the boiler system and the vehicle operation in the warehouse. In order to develop a mathematical model for labor requirement, the data that Vosloh (1968, 1976) constructed for labor requirement in his model mill are used by assuming that his model mill is similar to this model, in terms of labor assignment standards. Maintenance and repair costs are obtained by assuming to be 5.5% of the total capital investment cost. Also, supplies and miscellaneous costs are estimated by using Vosloh's report and it is approximately 0.87 dollars per ton based on daily production.
