........Today very Important .Thanks

Answer 1

1.

1. Define the problem
2. develop a model
3. acquiring input data
4. develop a solution
5. test the solution
6. analyze the results
7. implement the results.

2.

What problems occur when defining a problem?

1. Conflicting viewpoints: The first difficulty is that quantitative analysis must often consider conflicting viewpoints in defining the problem.
2. Impact on other departments: problems don't exist in isolation and are not owned by one department of a firm,when a solution is found all areas of the organization should be informed.
3. Beginning Assumptions: People have a tendency to state problems in terms of solutions. From an implementation standpoint a "good" solution to the "right" problem is much better than an "optimal" solutions to the "wrong" problem
4. Solution outdated: the problem can change as the model is being developed, one of the benefits of mathematical models is that once the original model is developed it can be used over and over again.

What problems occur when developing a model?

1. Fitting the textbook model: developing quantitative models is a managers perception of a problem and wont always match the textbook approach.
2. Understanding the model: the trade off between the complexity of the model and the ease of understanding, models need to be easy to understand.

What problems occur when Acquiring input data?

1. Using accounting data: most data generated in a firm come from basic accounting reports
2. Validity of data: lack of good clean data means that whatever data is available must often be distilled and manipulated before being used in a model, the validity of the results of the model is no better than the validity of the data going into the model.

3. The transportation problem is a special type of linear programmingproblem, where the objective is to minimize the cost of distributing a product from a number of sources to a number of destinations.

4. North West Corner Method (NWCM) , Least Cost Method (LCM) and Vogel's Approximation Method (VAM) are the classical methods for solving transportation problems.

5. So far in the literature, there are mainly four methods so called EnumerationMethod, Simplex Method,Transportation Method and HungarianMethod for solving Assignment Problem.
