Mechanical maintenance jobs of technical and economic evaluation model

Return on investment protection and recovery operation speed of the original investment. To simplify the problem, using the static fT model payback period for a △ P / NB-min 743> ll97 investment recovery of / a3.05.0 yield return on investment limits / m4884ll990 unit volume of savings / investment element ml1.597.74 mechanical / repair is the life cycle of 5,660,[link widoczny dla zalogowanych],092,800 yuan /? 1 l2> l2 (2) mechanized maintenance operation of the unit conversion costs were significantly reduced, the quality of road repair is much higher than the quality of manual work. Therefore, according to the quality of comparability requirements, response unit conversion calculation results with the correction, correction factor k a t / t. , Where t is the use of the new program cycle,[link widoczny dla zalogowanych], t. The life cycle of the original program. The data in Table 1, the unit conversion cost of manual operation Z is a Zk a correction 2Zm (3) the second lowest cost unit conversion program, the reason is the different operating processes, according to the second program operation can be recycled and used part of the old material, thus saving material costs,[link widoczny dla zalogowanych], the operating costs. However, the scope of this process method to be further verified. (4) Only the year when production reached a certain scale,[link widoczny dla zalogowanych], the use of integrated maintenance vehicle operations is the economy. 3 Conclusion (1) integrated application unit conversion cost model, cost-effectiveness model and the payback period model can be more comprehensive analysis and evaluation of mechanical maintenance work in the technology economy. (2) application of the above model, we must consider the comparability and quality of the actual operating results and processes on an amendment. (3) The calculation of the cost of the program,[link widoczny dla zalogowanych], the program should be fully examined and included in direct costs and indirect costs associated with in order to ensure the accuracy of the results.
