Calculate MAD, MSE, SFE, and TS for both forecasts for the nine
months displayed. Which performed better? Make forecasts for the
first three months of 2008 by both methods.
Solve any two of following: 10
Define operation research? Explain its development?
Explain the scope of operation research in Management?
What is importance of strategic decision in operation?
Q.2 Define Forecasting? Write its methods in details? 10
Write note on any two: 10

Q.3 The Rocky Mountain Arsenal, formerly a chemical warfare
manufacturing site, is said to be one of the most polluted locations
in the United States. Cleanup of chemical waste storage basins will
involve two operations.
10
Operation Drain and dredge basin.
Operation Incinerate materials.
Management estimates that each operation will require the following
amounts of time (in days):

Storage Basin
A B C D E F G H I J
Dredge 3 4 3 6 1 3 2 1 8 4
Incinerate 1 4 2 1 2 6 4 1 2 8
Management's objective is to minimize the makespan of the cleanup
operations. All storage basins are available for processing right now.
First, find a schedule that minimizes the makespan. Then calculate
the average flow time of a storage basin through the two operations.
What is the total elapsed time for cleaning all 10 basins? Display the
schedule in a Gantt machine chart?
Solve any two of the following: 10
Explain JIT implementation system in detail.
Write a note on lean production.
Explain the importance of Inventory Control System.
Q.4 Explain in detail KANBAN technique. 10
Solve any two of the following: 10
Explain the importance of Inventory Control System.
What is role of inventory in Industries?
Write note on supply chain management.
Q.5 Use the sales data given below to determine: 10
the least squares trend line, and
ii) the predicted value for 2008 sales.
Year Sales (Units)
2001 100
2002 110
2003 122
2004 130
2005 139
2006 152
2007 164
To minimize computations, transform the value of x (time) to simpler
numbers. In this case, designate year 2001 as year 2002 as year
etc.
Solve any two of following: 10
Discuss in detail Gantt chart?
Write note on Project Scheduling?
Write note on Project Controlling.
