AE-92-1  aA thesis submitted in partial fulfillment of the requirements for the Degree of Master of Engineering, School of Environment, Resources and Development  aThesis (M.Eng.) - Asian Institute of Technology, 1992  aA menu driven computer software was developed for optimization of farm  machinery system with flexibility to incorporate regional variations in crops and  cropping patterns, farm equipment sizes, a nd costs of the resources and outputs.  The Decision Support System (DSS) calculates the optimum power required for  field, transportation, irrigation and post harvest operations; and selects the  optimum power source(s) and matching equipment from those available in the  region. It also computes working hours required; energy used; fixed, operating  and timeliness costs for t h e farm operations on crop, seasonal and annual basis.  The DSS can also compute net returns per ha of crop and per ha of land holding.  Two sources of mobile power, tractor and animals; and two sources of  stationary power, electric motor and diesel engine were considered. Provision was  made to opt for all possible combination of power sources for different stationary  operations. For farmers growing three crops a year in each farm field analysis  of case studies shows that up to 8 ha of land holding combination of animals  and electric motor as power sources was most economical beyond which a  combination of tractor and electric motor was most economical. However,  depending upon the availability of custom work, a farmer can own a tractor  economically with less than 8 ha land holding. 0aDecision support systems 0aAgricultural machineryzIndia, Western1 aSingh, Gajendra,eChairperson1 aGee-Clough, D.,eExamination Committee1 aGupta, Chandra P., eExamination Committee1 aMaohua, Wang, eExamination Committee1 aSalokhe, Vilas M.,eExamination Committee2 aThe British Government, eScholarship Donor2 aAsian Institute of Technology.tThesis ;vno.
