Discuss appropriate method to make unbalanced transportation problems small allocation e is placed in the least cost and independent cell (1 5).

Consider the matrix giving the first feasible solution. To test the optimality of the solution we start with an empty cell (i.e.

vectors are linearly independent? The solution to a transportation problem with m-rows and n-columns is ... C. Highest costly cell of the table.

Solution: Starting from the North West corner we allocate min (50

fundamental issues of the Fuel Cell as an "integrated system". Advances are being made in the independent cell voltage (stack efficiency) is assumed.

The Transportation Problem: LP Formulations An LP Formulation Suppose a company has m warehouses and n retail outlets A single product is to be shipped from the warehouses to the outlets Each warehouse has a given level of supply and each outlet has a given level of demand We are also given the transportation costs between every

The transportation algorithm is generalized and given new interpretations Next a special highly efficient algorithm the tree algorithm is developed for solution of the maximal flow problem 6 1 THE TRANSPORTATION PROBLEM The transportation problem was stated briefly in Chapter 2 We restate it here

In this chapter we discuss three special types of linear programming problems: transporta- tion assignment and transshipment Each of these can be solved by the simplex algorithm but specialized algorithms for each type of problem are much more ef?cient 7 1Formulating Transportation Problems

Optimality in Transportation Problem - Stepping Stone Method •This method involves evaluation of each unoccupied cell for opportunity cost •If opportunity cost of any unoccupied cell is positive (if more than one unoccupied cell has positive opportunity cost then the cell with maximum positive OC) then this cell is bought in the solution

ing transportation problem Step 2: 1-ind an adjacent better basic feasible solution Step 3: Perform step 2 until no better adjacent basic feasible solution can be obtained Step 2 deals with the determination of a cell (ij) not in the basis which if introduced into the basis will reduce the time of transportation or reduce the allocation

If a basic feasible solution to a transportation problem contains exactly m+n-1 allocations in independent positions it is called a non degenerate basic 

TRANSPORTATION PROBLEMS Assumptions • Unit transportation costs are independent of transported volume • Supply and demand are known and independent on 

In this section we give two examples to show how to model an inventory planning problem and a production problem as transportation problems Example 1

The transportation problem is one of the sub class of linear programming The allocated cells in the transportation table will be called occupied

This solution has 3+4–1 = 6 occupied cells These are independent as it is not possible to form any closed loop through these allocations (see Fig 4 2) ?

Every loop has an even number of cells and has at least four cells 2 The allocations are said to be in independent position if it is not possible to increase
