Advertising Awareness
Differential equations are widely used to describe a variety of dynamic processes in Economic Sciences, Business and Marketing. Below we consider how an advertising campaign can be simulated using differential equations.
Imagine that a company has developed a new product or service. The marketing strategy of the company involves aggressive advertising. To construct the simple model we introduce two variables:
- The quantity
represents advertising activity that is described by spending rate, for example, by the amount of dollars (euros, pounds) the company spends for advertising per week; - The quantity
represents awareness of the target group of potential consumers about the new goods or services.
Thus, we will consider the market niche as a black box (Figure
A simple model of such type was proposed in
where
The given equation contains two terms in the right side. The first term
This equation is a Linear Differential Equation of First Order. It's convenient to rewrite it in the standard form:
The integrating factor is the exponential function:
Therefore the general solution of the given differential equation is given by
As usual, the constant of integration
In the examples below we consider how awareness of customers
