G 40 E, F
H 25 D, G
Create a precedence diagram
Calculate the Workstation Cycle Time
Calculate the Theoretical Minimum Number of Workstations
Assign tasks, one at a time, to the first workstation until the sum of the task times is equal to the workstation cycle time (don’t exceed WCT). Draw those workstations on your precedence diagram.

The uptowner just paid an annual dividend of $4.12. the company has a policy of increasing the dividend by 2.5 percent annually. you would like to purchase shares of stock in this firm but realize that you will not have the funds to do so for another four years. if you require a rate of return of 16.7 percent, how much will you be willing to pay per share when you can afford to make this investment?

M. cotteleer electronics supplies microcomputer circuitry to a company that incorporates microprocessors into refrigerators and other home appliances. one of the components has an annual demand of 235 units, and this is constant throughout the year. carrying cost is estimated to be $1.25 per unit per year, and the ordering (setup) cost is $21 per order. a) to minimize cost, how many units should be ordered each time an order is placed? b) how many orders per year are needed with the optimal policy? c) what is the average inventory if costs are minimized? d) suppose that the ordering cost is not $21, and cotteleer has been ordering 125 units each time an order is placed. for this order policy (of q = 125) to be optimal, determine what the ordering cost would have to be.

Joint cost cheyenne, inc. produces three products from a common input. the joint costs for a typical quarter follow: direct materials $45,000 direct labor 55,000 overhead 60,000 the revenues from each product are as follows: product a $75,000 product b 80,000 product c 30,000 management is considering processing product a beyond the split-off point, which would increase the sales value of product a to $116,000. however, to process product a further means that the company must rent some special equipment costing $17,500 per quarter. additional materials and labor also needed would cost $12,650 per quarter. a. what is the gross profit currently being earned by the three products for one quarter? $answer b. what is the effect on quarterly profits if the company decides to process product a further? $answer
