Determination of Multiple Dosing Parameters: Loading and Maintenance Doses

110
A loading dose is an essential pharmacological strategy to rapidly achieve the target plasma drug concentration necessary for an immediate therapeutic effect. This approach is especially critical for drugs characterized by slow absorption or extended half-lives, where delaying therapeutic plasma levels could compromise treatment outcomes. By administering a loading dose, clinicians ensure a prompt onset of drug action, even for agents with complex pharmacokinetic profiles.Achieving steady-state...

Parameters Affecting Nonlinear Elimination: Zero-Order Input, First-Order Absorption and Two-Compartment Model

206
Drugs administered through various routes can lead to nonlinear elimination, resulting in complex pharmacokinetic behaviors crucial to understanding efficacious drug dosing.
When a drug is administered through a constant intravenous infusion and eliminated via nonlinear pharmacokinetics, it follows zero-order input. For example, oral drugs undergo first-order absorption upon administration and are eliminated through nonlinear pharmacokinetics.
In the case of subcutaneously administered drugs,...

Multimachine Stability01:25

Multimachine Stability

470
Multimachine stability analysis is crucial for understanding the dynamics and stability of power systems with multiple synchronous machines. The objective is to solve the swing equations for a network of M machines connected to an N-bus power system.
In analyzing the system, the nodal equations represent the relationship between bus voltages, machine voltages, and machine currents. The nodal equation is given by:

Area of Science:

  • Operations Research
  • Supply Chain Management
  • Financial Engineering

Background:

  • Retailers face non-stationary stochastic demand, requiring dynamic inventory management.
  • Demand uncertainty poses significant risk, impacting profitability and operational efficiency.
  • Integrating financial decisions with inventory management is crucial for robust strategies.

Purpose of the Study:

  • To develop optimal inventory and financing policies for retailers facing uncertain demand.
  • To analyze the impact of option contracts and financial flexibility on inventory decisions.
  • To provide a recourse approach for solving the two-stage optimization problem.

Main Methods:

  • Bayesian approach for updating demand information.
  • Two-stage stochastic optimization model.
  • Recourse method to derive optimal inventory and financing policies.

Main Results:

  • The optimal option procurement policy exhibits a two-threshold base-stock structure.
  • Policy effectiveness depends on initial procurement, demand updates, and financial state.
  • Initial demand significantly influences the decision to use secondary procurement opportunities.

Conclusions:

  • The study integrates financial and operational decisions with demand updates for enhanced inventory management.
  • New managerial insights are provided for retailers navigating demand uncertainty and financial constraints.
  • Optimal policies offer a framework for balancing risk and resource allocation in retail operations.
