What kind of problems can we solve by using Solver?
The Excel Solver add-in is especially useful for solving linear programming problems, aka linear optimization problems, and therefore is sometimes called a linear programming solver. Apart from that, it can handle smooth nonlinear and non-smooth problems.
What are the transportation and transshipment problems?
The transshipment problem is a special case of the transportation problem in which shipping paths can include intermediate points. For example, shipping from Los Angeles to New York via Denver may be less expensive than shipping directly (non-stop) to New York.
What is the transhipment problem?
What is transshipment problem in linear programming?
The transshipment problem is a unique Linear Programming Problem (LLP) in that it considers the assumption that all sources and sinks can both receive and distribute shipments at the same time (function in both directions).
What can Excel Solver do?
Excel Solver – What Solver Can and Cannot Do
- Your model size (number of decision variables and constraints, total number of formulas)
- The mathematical relationships (e.g. linear or nonlinear) between the objective and constraints and the decision variables.
- The use of integer constraints on variables in your model.
What is transportation problem explain with example?
The transportation problem is a special type of linear programming problem where the objetive consists in minimizing transportation cost of a given commodity from a number of sources or origins (e.g. factory, manufacturing facility) to a number of destinations (e.g. warehouse, store).
What do you mean by transhipment problem?
The transshipment problem is a unique Linear Programming Problem (LLP) in that it considers the assumption that all sources and sinks can both receive and distribute shipments at the same time (function in both directions)
What is the transshipment model?
Transshipment model is a multi-phase transport problem in which the flow of material – raw materials and services is interrupted in at least one point between the origin and the destination. The whole stock passes through intermediate points of reloading before the goods reach their final destination.
What is the difference between transportation and transshipment problems?
Answer. Answer: Transshipment is like the child of the transportation but in transshipment we have some areas (like warehouses) which the goods from supply points were shipped to these points which are in the middle of the demand and supply points and then they were shipped from these points to the demand points.

What is Excel Solver used for?
A solver is a mathematical tool present in MS-Excel that is used to perform calculations by working under some constraints/conditions and then calculates the solution for the problem. It works on the objective cell by changing the variable cells any by using sum constraints.
How to solve a transportation problem in Excel?
Use the solver in Excel to find the number of units to ship from each factory to each customer that minimizes the total cost. The model we are going to solve looks as follows in Excel. 1. To formulate this transportation problem, answer the following three questions. a. What are the decisions to be made?
Which function is used to calculate the total shipped?
Insert the following functions. Explanation: The SUM functions calculate the total shipped from each factory (Total Out) to each customer (Total In). Total Cost equals the sumproduct of UnitCost and Shipments. With this formulation, it becomes easy to analyze any trial solution.
How do I use the solver add-in in Excel?
On the Data tab, in the Analyze group, click Solver. Note: can’t find the Solver button? Click here to load the Solver add-in. Enter the solver parameters (read on). The result should be consistent with the picture below. You have the choice of typing the range names or clicking on the cells in the spreadsheet.
