Prepare a schedule for the following situation: the forecast is 80 units for each of the first two periods and 60 units for each of the next three periods. the starting inventory is 20 units. the company uses a chase strategy for determining the production lot size, except there is an upper limit on the lot size of 70 units. also, the desired safety stock is 10 units. note: the atp quantities are based on maximum allowable production and do not include safety stock. committed orders are as follows: (negative amounts should be indicated by a minus sign. leave no cells blank - be certain to enter "0" wherever required.)

Acommercial grade cubical freezer, 4 m on a side, has a composite wall consisting of an exterior sheet of 5.0-mm thick plain carbon steel (kst= 60.5 w/m k), an intermediate layer of 100-mm thick polyurethane insulation (kins 0.02 w/m k), and an inner sheet of 5.0- mm thick aluminium alloy (kal polyurethane insulation and both metallic sheets are each characterized by a thermal contact resistance of r 2.5 x 104 m2 k/w. (a) what is the steady-state cooling load that must be maintained by the refrigerator under conditions for which the outer and inner surface temperatures are 25°c and -5°c, respectively? (b) for power saving purpose, which wall material should be increased/reduced in. thickness in order to reduce 50% of the cooling load found in part (a)? redesign the thickness of the proposed material. 177 w/m-k). adhesive interfaces between the q=575.93 w
