32. Why simplex method is used ?

ans- for linear programming . 

 

33. What is the basis of Halsey plan ? 

ans- It is a wage incentive plan which ensures minimum wage for a worker and bonus is paid for the fixed percentage of time he/she saved. 

 

34. What is job evaluation ? 

ans- Evaluating the value of a job in relation to other jobs .
