Microeconomics is a branch of economics that studies the behaviour of individuals or households or firms (economic agents) in making decisions regarding the allocation of limited resources.
It is concerned with the interaction between individual buyers and sellers and the factors that influence the choices made by buyers and sellers.
In particular microeconomics focuses on patterns of supply and demand and the determination of prices and output in individual markets, and that how individual businesses decide how much of something to produce and how much to charge for it.

The Intuitive Lowest Cost Method

The Intuitive Lowest Cost Method Or The Minimum Cell Cost Method

The Intuitive Lowest Cost Method is a cost based approach to finding an initial solution to a transportation problem.
It makes allocations starting with the lowest shipping costs and moving in ascending order to satisfy the demands and supplies of all sources and destinations.

This straightforward approach uses the following steps.
Identify the cell with the lowest cost.Allocate as many units as possible to that cell without exceeding the supply or demand.Then cross out the row or column or both that is exhausted by the above assignment.Move on to the next lowest cost cell and allocate the remaining units.Repeat the above steps as long as all the demands and supplies are not satisfied. 
When we use the Intuitive Approach to the Bengal Plumbing problem, we obtain the solution as below.

Vogel's Approximation Method (VAM)

The Vogel's Approximation Method

In addition to the North West Corner and Intuitive Lowest Cost Methods for setting an initial solution to transportation problems, we can use another important technique - Vogel's Approximation Method (VAM).
Though VAM is not quite as simple as Northwest Corner approach, but it facilitates a very good initial solution, one that is often the optimal solution.
Vogel's Approximation Method tackles the problem of finding a good initial solution by taking into account the costs associated with each alternative route, which is something that Northwest Corner Rule did not do.

To apply VAM, we must first compute for each row and column the penalty faced if the second best route is selected instead of the least cost route.

To illustrate the same, we will look at the Bengal Plumbing transportation problem.

A market in any one of a variety of different systems, institutions, procedures, social relations or infrastructures whereby persons trade, and goods and services are exchanged, forming part of the economy. It is an arrangement that allows buyers and sellers to exchange things. Markets vary in size, range, geographical scale, locations, types and varieties of human communities, as well as in the types of goods and services traded. Some Examples include, local farmer's market held in town squares, Shopping Centres or shopping malls, Financial Markets such as International currencies or commodity markets or Equity stock markets, legally centred markets such as pollution permits, and illegal markets such as black markets for illicit drugs or weapons. In mainstream economics, the concept of market is any structure that allows buyers and sellers to exchange any type of goods, services and information. The exchange of goods or services for money is called a transaction. Thus a market ha…
