the sphere of influence of the density of the customer population of a service centre is high near the service centre but decrease with increasing distance due to the frictional effects of the distance

and inconvenience of travel. This means that customers living closer to the service centre are more likely to use its services regularly, while those living further away may only use it occasionally or not at all. Businesses should take this into consideration when planning their marketing and expansion strategies, ensuring that they focus on capturing and retaining customers within their primary sphere of influence. This may involve targeting specific geographic areas, offering incentives for local customers, or opening additional service centres in areas with high population density. By understanding and leveraging the dynamics of customer density, businesses can optimize their operations and enhance their overall profitability.
