The optimization criteria of the multimodal transport problem described above are two objective functions of minimizing total transportation costs and level of transport risks. The object of this study is a multicriteria transport problem, being stated for availability of several means of cargo delivery, meaning a multimodal transport problem.

In this article, the authors present proposals how to generate data comparatively easy, apply traditional MS Excel generation tools as well as tools of Goal Seek and Solver. It was found out that the data generation resulted in higher marks both in UCIS and many other study courses. Investigations were performed in the Red Cross Medical College of Rīga Stradiņš University (RCMC of RSU). The authors of the present article offer an acceptable solution – data associated with the health care patients are generated from the parameters of statistics of scientific publications. Their use is strictly regulated/ legislation.

The data of the health care patients are of a special status. The UCIS work/study material can be associated with various branches, including health care. The inquiry results show evidence that an important role in the acquisition of UCIS has the work/study material – data. First of all, the authors inquired students in order to find out their attitude to the UCIS. The authors of the present article are investigating the influence of the data generation in the university courses of informatics and statistics (UCIS) on the acquisition of both the UCIS and other study courses in the health care specialities. Constraints: The limitations or requirements of the problem are expressed as inequalities or equations in decision variables.The objective may be maximizing the profit, minimizing the cost, distance, time, etc.,

Objective function: The objective of the problem is expressed as a mathematical expression in decision variables.

These variables represent unknown quantities (number of items to produce, amounts of money to invest in and so on).

Decision variables: The decisions of the problem are represented using symbols such as X 1, X 2, X 3 ,….X n.

The model consists of following components: For the given problem, we formulate a mathematical description called a mathematical model to represent the situation. This may be maximizing the profit, minimizing the cost, minimizing the total distance travelled or minimizing the total time to complete a project. In these problems, we find the optimal, or most efficient, way of using limited resources to achieve the objective of the situation. Introduction Optimization problems are real world problems we encounter in many areas such as mathematics, engineering, science, business and economics. We work through examples from different areas such as manufacturing, transportation, financial planning, and scheduling to demonstrate the use of Solver. This is especially useful for interdisciplinary courses involving optimization problems. All of these in keeping the departure times intact.We illustrate the use of spreadsheet modeling and Excel Solver in solving linear and nonlinear programming problems in an introductory Operations Research course. And the ones to be used have to be optimized for shortest distance so fuel cost would be minimized.

How do we optimize the usage of planes? Minimum number of planes is one goal. We don’t have to use them all for this trip. The 2 nd worksheet has the list of Jets with their respective locations. The first worksheet has flight sample data.

To use Solver, we will need to define an objective function to minimize or maximize.

Can you provide sample input data for the problem?.

Yes it’s a similar scenario and I found an excel example online ( ) for a VPR but it doesn’t do what I want.

There is something called the fleet assignment problem, I am trying to determine if this is the case.

Another input is a list with the desired origin-destination legs for each customer.

But keep in mind we want the closest available plane to reposition. If there are no more planes departing from a certain location on that day, will the customer stay overnight? No, we have to provide a plane if customer has already book even if it means we have to reposition a plane from a distance location.

Another input is the current time of day.

One input for the problem is a list of available planes, with their respective locations.
