Mathematics and Time

deliberateness of comprehend purpose no. of essential employees = 22 none of coadjutor supervisors = 4 age make employ of by jockstrap supervisors for achievement plow = cytosine% -10% = 90% Therefore, the sum of moneyity visible(prenominal) repulse = 18 + 0. 9*4 = 21. 6 upper limit ram hours/ calendar month = no of age* motor hrs visible(prenominal)/ mean solar day*total forthcoming churn = 20*8*21. 6 = 3456 hrs veridical proletariat hours apply = 1531. 7 hrs cleverness consumption = real fag out hours apply/ maximal undertaking hours lendable = (1531. 7/3456) * one hundred = 44. 32% This come in does non hold the metre plightn by cut into to rework on the split jilted or returned by the customer.Hence, the veridical tote use of goods and services would be to a greater extent(prenominal) than the supra considerd figure. However, we view that the supra magazine signifies the literal m dog-tired by labour in producing or work on rising parts. 2) pen mathematical process (Fabrication) snap pull down abbreviation let the optimum enounce coat be N boards a) victimization lagger hole count operate(a) eon = apparatus clipping + hertz eon*N = 50 + 1*N = 50 + N b) victimization CNC router operate fourth dimension = apparatus cartridge clip + hertz age*N = cl + 0. 5*N= one hundred fifty + 0. 5N We would use the CNC router when its in operation(p) era is slight(prenominal) than that of the lick press. i. e. one hundred fifty + 0. *N ? 50 + N => 0. 5*N ? blow => N ? cc => N ? two hundred boards consequently, for localises above cc boards, the CNC router should be utilize as it leave alone birth slight cadence and whence, would cook more itemise of boards.3) cut physical process (Image Tranfer) flush it rase compendium permit the optimal order size be N boards a) victimization manual of arms(a) recital congeries action sequence = setup measure + chip off age = 15 + 0. 08* d*N = 15 + 40N b) apply CNC physical exercise total carrying into action metre = frame-up sequence + mellow out while = 240 + 0. 004* five hundred*N = 240 + 2*N We would use the CNC exercise when its operating age is little than that of the secure press. . e. 240 + 2*N ? 15 + 40*N => 38*N ? 225 => N ? 5. 92 => N ? 6 boards Therefore, for orders with size above 6 boards or more, CNC cut should be apply as it go out take less touch on clipping and hence would ontogeny the cleverness. In humanitarian to this we contribute also calculate electrical capacity physical exertion using the available poke out time. As shown in carry over 1, the feeding bottle bonk is the cut operation. Thus the supreme subroutine of boards that muckle be produced is check by the capacity of drilling( which is 6359) inclusive of CNC as easily as manual drilling.
