Question 2 a. Discuss the concept of Degeneracy in transportation problem
b. The ABC Tool Company has a sales force of 25 men who work out from Regional offices. The
company produces four basic products linesof hand tools. Mr. Jain, the salesmanager, feelsthat 6
salesmenare neededtodistribute productline 1, 10 salesmenare neededtodistribute productline
2, 4 salesmen to product line 3 and 5 salesmen to product line 4. The cost per day of assigning
salesmen from each of the offices for selling each of the product lines are as follows;
Regional office Product Lines
𝑷𝟏 𝑷𝟐 𝑷𝟑 𝑷𝟒
R1 20 21 16 18
R2 17 28 14 16
R3 29 23 19 20
Now, 10 salesmen are allowed to office R1, 9 salesmen to office , and 7 salesmen to office .
How many salesmen should be assigned from each office to selling each product line in order to
minimize costs?
Degeneracy in transportation problem
Optimum allocation.

2. Optimum transportation cost
Answer: a) Degeneracy in transportation problem
A basic solution to an m-origin, n destination transportation problem can have at the most m+n-1
positive basicvariables(non-zero),otherwisethe basicsolutiondegenerates.Itfollowsthatwhenever
the numberof basic cellsislessthan m + n – 1, the transportationproblemisa degenerate one.The
degeneracy can develop in two ways:
Case 1 - The degeneracy develops while

How should the tasks be allocated to subordinates to minimize the total man-hours?
A Description of assignment problem
Optimum allocation through Hungarian method
Answer: a) An assignment problem is a special type of transportation problem. In an assignment
problem,the same numberof facilities(sourcesof supply) needstobe allocatedtothe same number
of jobs(pointsof destinations) so thatthe transportationcostisminimisedorthe profitismaximised.
An assignment problem can occur while assigning:
 Machines to factory orders
 Salespeople to sales territories
 Teachers to classes
 Police vehicles to patrolling areas

Question 2. Define following criteria’s used for decision making under Uncertainty
a. Optimism (maximax or minimin) criterion
b. Pessimism (maximin or minimax) criterion
c. Equal probabilities (Laplace) criterion
d. Coefficient of optimism (Hurwicz) criterion
e. Regret (salvage) criterion
Answer: a) Optimism (maximaxor minimin) criterion: Here,the decisionmakertriesto achieve the
largest possible profit (Maximax) or minimum possible cost (minimin).If the entries in the payoff
matrix are the one which the decisionmakerwantsas large as possible,forexample,profitsorsales
revenue,he/sheselectsthe alternative thatrepresentsthe maximumof the maximumpayoff.Incase
where the entriesof the payoff matrix are one which the decisionmakerwants as small as possible,
he/she goes for the minimum of the
Question3a. Explainthe importance andutilityofthe replacementmodel inbusinessorganizations.
b. The maintenance cost and re-sale value per year of a machine whose purchase price is Rs. 7000
is given below-
Year 1 2 3 4 5 6 7 8
Maintenance cost (Rs.) 900 1200 1600 2100 2800 3700 4700 5900
Resale value (Rs.) 4000 2000 1200 600 500 400 400 400
Importance and utility of the replacement model Replacement Year
Answer: a) In an organisation, replacement problems arise when fixed assets, such as machines,
equipment, and other tools, need to be replaced due to reduced efficiency, failure or breakdown.
Sometimes,replacementtakesplace when more efficientequipmentisavailable inthe marketorthe
maintenance of the existing equipment is incurring a huge cost on an organisation. However, an
organisation needs to decide when the
