ASSIGNMENT # 1 (Total 100 points)
Due in 7th August (Thursday) simply by 5pm
Be sure to write the identity, student # and section #
for each scholar in the group on the cover page with the assignment 1 ) Suppose you/your group are the owners of a company that produces ereading gadgets. The present development rate is 1000 e-readers /day plus the selling price is definitely $210/unit. It needs 200 employees working eight hours/day to make the e-readers and they are paid $20/hour. The fabric cost is $100/unit and cost to do business cost is 50 dollars, 000/day. a)What is the unitless multi-factor (labor + material + overhead) productivity proportion? b)What is a labor productivity ratio (both unitless in addition to terms of units/labor hour)?
You/your group is thinking about buying a new expensive machine that is quite complex to handle but will improve the quality of the product. The availability rate raises to 1200 e-readers /day, material expense will decrease to $90/unit and the expense cost raises to hundred buck, 000/day (to pay for the depreciation with the machine). It will eventually still require 200 workers working almost 8 hours daily (now to produce 1200 units); however the labor rate will probably be $30/hour. c)What will be the unitless multi-factor (labor + materials + overhead) productivity rate with the new machine?
2 . An e-retailer of one's saving devices is able to collect the data pertaining to customer demand (in million $) from the website for any new product. Yet , due to lack in inventory, it is not in a position to fulfill each of the requests. Require and actual sales intended for the initially nine weeks of 2009 are given under.
MonthDemand (in mil $)Sales (in mil $)
Jan sixty 54
Feb eighty six 80
March ninety six 83
April 111 83
May a hundred and fifty 107
June 139 113
July 157 150
August 164 159
September 171 165
a)Which data, revenue or require, should be used if the e-retailer wants to forecast its demand for Oct 2009 вЂ“ Dec 2009? Argue briefly. b)Use a 3-month moving average to forecast demand by October 2009 to January 2009. c)Use exponential smoothing with О± = zero. 25 to forecast with regard to October 2009 вЂ“ January 2009. Assume that the initial forecast for January is comparable to the actual of sales or receipts (depending on your solution in (a)) for January.
Demand and revenue in Oct, November and December proved as follows:
MonthRequests (in mil $)Sales (in mil $)
October 176 170
November 191 188
December 130 a hundred and twenty-five
d)Based within this new info, recalculate demand forecast pertaining to November 2009 вЂ“ 12 , 2009 to get both 3-month moving common and dramatical smoothing (О± = zero. 25) approaches. e)Based upon actual and forecasts to get April-December 2009, compute ANGRY and MSE for 3-month moving normal and rapid smoothing (О± = 0. 25) techniques (Hint: Make use of the forecasting result up to August calculated in some parts (b) and (c) plus the forecasting end result for Nov 2009 вЂ“ December 2009 calculated partly (d)). f)Based on your solution in (e), which foretelling of technique do you prefer? g)In general, remedy you think managers prefer ANGRY over MSE (to decide on which foretelling of technique is preferable) and the other way round?
3. The demand pertaining to electrical power in the Montreal region for 2003-2009 is shown below, in megawatts:
YearPower Require (MW)
a)Use double exponential smoothing for these data to forecast with regard to 2010-2012. Presume О± = 0. four and ОІ = 0. 2 and begin with primary estimates of average for 2003 while 74MW and trend for 2003 because 5MW. b)If the demand for 2010 turns out to be 125MW, what will always be the demand forecast for 2011-2012 (О± sama dengan 0. four and ОІ = zero. 2)?
