MGMT 335 1. Lovely-Tech Company produces printers. In January, the company produced 4200 printers per week. The company has 28 direct labor employees. Each employee works 40 hours per week with an hourly wage of $25.00. The material cost of the firm per week is $16,000.00. The overhead expense incurred in operating the firm is $12,000 per week. (1) Determine the weekly multi-factor productivity of the Lovely-Tech Company in January. (Hint: Total input = Labor cost + Material cost + Overhead) (Labor cost number of employees * working hours a week * wage) (2) In February, Lovely-Tech Company has reengineered its production line with new machine. The current production process made 4,600 printers per week and required only 26 direct labor employees. Suppose the material cost and the overhead remain the same, what is growth rate (in percentage) in weekly multi-factor productivity from January to February? 2. Here is an Activity on Arrow (AOA) network diagram for a project. The lettered A through H represents a sub- project, as shown in the accompanying precedence diagram. 1 E B D 3 F H 7 8 Time Activity Time Activity A 5 E 6 B 6 F 4 C D 3 8 H 8 3 Please answer the following questions: (1) Which path is the critical path? What is the expected duration of the project? (2) What are the Earliest Start (ES), Earliest Finish (EF), Latest Start (LS), Latest Finish(LF) and Slack time for each activity. 3. A small business company is considering updating the current production line. There are two plans. For plan A, the fixed cost will be $54,000 and the variable cost will be $27 per unit after the update. For plan B, the fixed costs will be $61,000 and the variable cost will be $26 per unit after the update. Please answer the following questions: (a) Suppose the selling price is $36, what is the break-even volume for each plan? Which plan has a lower break-even volume? (b) Suppose the selling price is $36. Also, the company aims to achieve a profit of $18,000 after the update. What selling volume will be required to achieve the profit for each plan? Which plan has a lower volume?
