- To minimize the total weekly idle waiting time for nurses.
- To incorporate essential constraints including maximum working hours, required rest periods, and shift staffing levels.
Main Methods:
- Formulation of a mathematical programming model.
- Inclusion of constraints for maximum weekly working time, minimum rest shifts (2 shifts), and variable shift staffing (min/max bounds).
- Utilization of LINGO8.0 software for solving the model and finding the global optimum solution.
Main Results:
- The model successfully minimizes nurses' total idle waiting time within a weekly planning horizon.

01:25Modeling with Differential Equations
Population dynamics can be described mathematically by considering the population size P(t) as a function of time. The rate of change of the population is then represented by the derivative of P(t). A simple assumption is that the rate of growth is proportional to the size of the population itself. This leads to an exponential growth model, where the population increases rapidly without bound. While this is a useful first approximation, it does not reflect realistic long-term...

Mechanistic models play a crucial role in algorithms for numerical problem-solving, particularly in nonlinear mixed effects modeling (NMEM). These models aim to minimize specific objective functions by evaluating various parameter estimates, leading to the development of systematic algorithms. In some cases, linearization techniques approximate the model using linear equations.

A silo with a cylindrical base, flat bottom, and hemispherical roof is a common design in agricultural and industrial storage due to its structural efficiency and ease of construction. Optimizing its dimensions to maximize storage capacity for a given amount of material—i.e., a fixed surface area—is a classic problem in applied calculus and engineering design. The key parameters are the radius r of the base and the height h of the cylindrical section.The total volume of the silo is obtained by...
