Ensuring Public Safety: A Mathematical Analysis of Lifeguard Scheduling at Garden City Beach

Garden City Beach, a popular tourist destination, hires temporary lifeguards each summer to ensure public safety. The lifeguards work five consecutive days each week and have two days off. The city's insurance requires a minimum number of lifeguards on duty each day to prevent accidents and ensure the well-being of beachgoers. In this article, we will analyze the mathematical aspects of lifeguard scheduling at Garden City Beach and explore the implications of this scheduling system.

The lifeguards at Garden City Beach work a total of 7 days each week, with 5 consecutive days of work and 2 days off. This scheduling system is designed to provide a balance between work and rest for the lifeguards, while also ensuring that there are enough lifeguards on duty each day to meet the city's insurance requirements.

Let's assume that the city requires a minimum of x lifeguards on duty each day. We can model the number of lifeguards on duty each day as a function of the number of days worked and the number of days off. Let's denote the number of lifeguards on duty each day as L(x).

The Number of Lifeguards on Duty Each Day

The number of lifeguards on duty each day can be calculated using the following formula:

L(x) = (5x + 2(7-x)) / 7

where x is the number of days worked.

Simplifying the Formula

We can simplify the formula by combining like terms:

L(x) = (35x + 14 - 14x) / 7

L(x) = (21x + 14) / 7

L(x) = 3x + 2

The Minimum Number of Lifeguards Required

The city's insurance requires a minimum of x lifeguards on duty each day. We can set up an equation to represent this requirement:

3x + 2 ≥ x

Subtracting x from both sides gives us:

2x + 2 ≥ 0

Subtracting 2 from both sides gives us:

2x ≥ -2

Dividing both sides by 2 gives us:

x ≥ -1

Since x represents the number of lifeguards on duty each day, it must be a non-negative integer. Therefore, we can conclude that x ≥ 0.

The Optimal Number of Lifeguards

To determine the optimal number of lifeguards, we need to consider the trade-off between the number of lifeguards on duty each day and the number of days off. A higher number of lifeguards on duty each day will provide greater safety, but it will also increase the cost of hiring and training lifeguards.

Let's assume that the city wants to hire a total of N lifeguards each week. We can set up an equation to represent this requirement:

5x + 2(7-x) = N

Simplifying the equation gives us:

35x + 14 - 14x = N

21x + 14 = N

Subtracting 14 from both sides gives us:

21x = N - 14

Dividing both sides by 21 gives us:

x = (N - 14) / 21

The Cost of Hiring Lifeguards

The cost of hiring lifeguards will depend on the number of lifeguards hired and the number of days they work. Let's assume that the cost of hiring a lifeguard for one day is C. We can set up an equation to represent the total cost of hiring lifeguards each week:

Total Cost = 5x * C + 2(7-x) * C

Simplifying the equation gives us:

Total Cost = 5x * C + 14C - 14x * C

Total Cost = (35x + 14 - 14x) * C

Total Cost = (21x + 14) * C

The Optimal Number of Lifeguards

To determine the optimal number of lifeguards, we need to minimize the total cost while ensuring that the city's insurance requirements are met. We can set up an equation to represent this requirement:

(21x + 14) * C = Minimize

Subject to:

3x + 2 ≥ x

x ≥ 0

In conclusion, the mathematical analysis of lifeguard scheduling at Garden City Beach reveals a complex trade-off between the number of lifeguards on duty each day and the number of days off. The city's insurance requirements must be met, while also minimizing the cost of hiring and training lifeguards. By using mathematical modeling and optimization techniques, we can determine the optimal number of lifeguards to hire each week and ensure the safety of beachgoers.

Based on our analysis, we recommend that the city of Garden City Beach hire a total of N = 21x + 14 lifeguards each week, where x is the number of days worked. This will ensure that the city's insurance requirements are met, while also minimizing the cost of hiring and training lifeguards.

Future research directions include:

  • Developing a more detailed model of the cost of hiring lifeguards, including the cost of training and equipment.
  • Investigating the impact of different scheduling systems on the number of lifeguards on duty each day.
  • Exploring the use of machine learning and artificial intelligence to optimize lifeguard scheduling.

By continuing to analyze and optimize lifeguard scheduling, we can ensure the safety of beachgoers and provide a high-quality experience for visitors to Garden City Beach.
Q&A: Lifeguard Scheduling at Garden City Beach
