Assignment I

Last Date of submission is 25 July, 2012, 12 noon.

1. Identify the three major functional areas of business organisations and briefly describe how they interrelate.

2. Differentiate between craft production and mass production. Is Lean Production different from these. How ?

3. List out the  ways in which service operations differ from manufacturing/production operations, explain with the help of an example.

4. The following table shows data on the average number of customers processed by several bank service units each day. The hourly wage rate is $25, the over head cost is 1.0 times the labour cost, and the material cost is $5/customer.
Unit              Employee                   Customers processed
A                      4                                         36
B                      5                                         40
C                      8                                         60
D                      3                                         20

a. Compute the labour productivity and multi factor productivity for each unit.
b. Suppose a new, more standardised procedure is to be introduced that will enable each employee to process one additional customer a day, compare the expected labour and multi factor productivity rates for each unit. For multi factor productivity assume an 8 hour day.

5. a. Why is time study and method study carried out in manufacturing environments ? Can we do a time study on a nurse at a hospital, Why ? What is the method adopted there ?
b. The average observed times (OT) of the five elements of a task done by different workers timed for twenty cycles each are as given below. 
Task    OT,secs     Rating
1            9               110
2           12              110
3           7.4             110
4           8.6             100
5           12.5           110


The allowances are 12 % of the normal time. Calculate the standard time. What is the standard output in a shift of 480 minutes ?


6. a. Explain the significance of the process chart symbols used for method study. What is a two handed process chart and a man machine chart ?
b. Draw a process chart for replacing the two old front tyres of an automobile with new tyres  in a tyre shop after purchase. What all steps can be eliminated or combined ? Draw the new process chart after analysis.
