An Information Value Approach to Route Planning for UAV Search and Track Missions
… has three contributions in the area of path planning for Unmanned Aerial Vehicle (UAV) Search And Track (SAT) missions. These contributions are: (a) the study of a novel metric, G, used to quantify the value of the target information gained during a search and track mission, (b) an optimal …

A microcomputer-based application of a cash decision model for small businesses
… and investment opportunities over a short-term planning horizon. Decision variables include timing, amount, and source of cash transactions. Decisions can be made regarding these variables such that the worth of the firm (i.e. outstanding investments less financing) at the end of the planning …

Autonomous Racing and Overtaking for the Voyager Unmanned Ground Vehicle
… weights and to investigate the effects of planning horizon length and obstacle avoidance formulation. Gazebo simulations are performed to evaluate real-time feasibility across different planning horizon lengths. A configuration with a planning horizon of three samples is found to feasibly …

Integrated Technology and Product Design Decisions With Market-Based Learning
… model with Bayesian learning over a finite planning horizon. Analytical results are derived for some special cases of the model. More specifically, the impact of manufacturing flexibility on the firm's design strategy in a single product case over a two-period planning horizon is analyzed. …

Managing pavement in a busy urban highway network
… first model characterizes over some medium-range planning horizon changes in peak-period traffic volumes, pavement conditions, vehicle miles traveled, and volatile organic compounds emissions. When used in optimal control exercises, this model determines the sequence and timing of maintenance, …

Multi-stage Stochastic Programming Models in Production Planning
… stochastic programming models in production planning, from both a modeling and an algorithmic point of view. We first consider a very simple multi-stage stochastic lot-sizing problem, involving a single item with no fixed charge and capacity constraint. Although a multi-stage stochastic …

Trajectory planning for unmanned vehicles using robust receding horizon control
… provides a good estimate of the path beyond the planning horizon, which is extended in this thesis to account for three dimensional motion; constraint tightening to ensure robustness to disturbances, which is extended to a more general class of disturbance rejection controllers compared to the …

The crane split and sequencing problem with clearance and yard congestion constraints in container terminal ports
One of the steps in stowage planning is crane split and sequencing, which determines the order of container discharging and loading jobs quay cranes (QCs) perform so that the completion time (or makespan) of ship operation is minimized. The vessel's load profile, number of bays and number of …

Discussão de critérios de operação de sistemas hidrelétricos interligados
… of only one stage being considered in the planning horizon. The objective functions analysed are a consequence of interconnected operation, where advantadges are taken from hydrological diversity among regions. The first criterion minimizes the expected sum of the energy overflows in each …

A Capacity Expansion Planning Method for A Regional Water Supply System (Illinois)
… demands are assumed to be increasing over a planning horizon and to be satisfied from several potential supply sources. In this study, a method has been developed to determine a water supply system layout and to size water production and transmission facilities in the system. The method is a …

Simulating the Adoption of Soil Conservation Management Systems Under the Conditions of Uncertainty (Erosion, Control)
… of soil erosion. Since conservation involves a planning horizon of more than one year, risk and uncertainty enter into the plans. Over time it is difficult to predict farm income due to variability in prices, costs, interest rates, weather, crop yields, and other unpredictable factors. Any …

Hydrologic-economic modeling of irrigated agriculture in the Lower Murrumbidgee Catchment : investigations into sustainability
… discounted net revenues from irrigation over the planning horizon is maximized by choosing annual areas planted to each crop in each of the economic subregions. The groundwater system is represented using a linear state-space model derived from a finite-difference approximation of the groundwater …
