Hospital Cost Functions and Quality
… when included in the specification of a hospital cost function. Also, this research estimates a value for scale economies in order to determine if the average hospital experiences increasing returns to scale in the production of hospital care, verifying such findings in previous econometric …

Online scheduling algorithms for broadcasting and general cost functions
… analysis to be tailored for specific objective functions. However, it is valuable to ask whether or not algorithms and analysis can be unified into a single algorithm or analysis framework. Motivated by this, we introduce the general-cost-function objective. In the general cost function, the …

Utility Accrual Real-Time Scheduling Under Variable Cost Functions
… CIC-VCUA, for tasks whose execution times are functions of their starting times. We model such variable execution times employing variable cost functions (or VCFs). The algorithm considers application activities that are subject to time/utility function time constraints (or TUFs), execution …

Optimal control problems on lie groups with symmetry breaking cost functions
In this thesis, we consider smooth optimal control systems that evolve on Lie groups. Pontryagin's maximum principle allows us to search for local solutions of the optimal control problem by studying an associated Hamiltonian dynamical system. When the associated Hamiltonian function possess …

Optimal state assignment of sequential circuits using a genetic local search with flexible cost functions
… targets design goals with the use of flexible cost functions. Our GLS quickly converges toward a globally optimal state encoding, producing high quality solutions. We explore the properties of encoding-based (calculated from the encoding values) and synthesis-based (calculated from synthesis …

A model to design a stochastic and dynamic ground delay program subject to non-linear cost functions
… overall air traffic congestion, and may lead to costly flight diversions. As a result, during periods of inclement weather, the FAA may implement a Ground Delay Program (GDP) to proactively delay flights on the ground before they depart and reduce the possibility of future airborne delays. …

Optimal Freight Service Quality and Implications for Economic Analysis, Inventory-Theoretic Shipper Cost Functions and Run-Through Train Operations
… freight service impacts the amounts, and hence costs, of both sets of resources. Optimal freight service quality (for a given volume level) minimizes the sum of carrier and relevant shipper costs (termed "full cost"). The shipper cost is dominated by inventory cost elements and does not include …

Valued Constraint Satisfaction Problems over Infinite Domains
… \emph{(valued) constraints} (also called \emph{cost functions}). More precisely, the input of a VCSP consists of a finite set of variables, a finite set of cost functions that depend on these variables, and a cost $u$; the task is to find values for the variables such that the sum of the cost …

Quantization of prior probabilities in Bayesian group decision-making
… given the true hypothesis, and an assignment of costs to different types of errors. In a setting with multiple agents and the principle of "one person, one vote", the decisions of agents are typically combined by the majority rule. This thesis considers collections of group hypothesis testing …

Shipping cost systems and structure in the Kingdom of Saudi Arabia : an analytical study
… is concerned with the analysis of shipping cost in theory and in the practice of Saudi shipping companies. Previous studies on cost structures and cost functions have been surveyed. Factors which affect each cost element have been derived from the surveyed studies to be used in establishing …

An algorithmic solution to the minimax resource allocation problem with multimodal functions
… resource allocation problem with multimodal cost functions. Unlike previous research in the same area which developed solutions for the same problem by imposing restrictions on the cost functions, such as the assumptions of monotoniciy or convexity, this approach is applicable to problems …

Cost functions and rents are very important to characterize the dynamics of industry behavior, as well …

Stochastic Model Predictive Control via Fixed Structure Policies
… of a control policy. Additionally, continuous cost functions are developed to allow training of the control policy in making discrete decisions, which is typically done with model-free learning algorithms. This general control policy encompasses a wide class of functions and allows the …
