Advanced Engineering Materials, EarlyView.A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

On the problem of the software cost function
Information and Software Technology, 2001Abstract The question of finding a function for software cost estimation is a long-standing issue in the software engineering field. The results of other works have shown different patterns for the unknown function, which relates software size to project cost (effort). In this work, the research about this problem has been made by using the technique

Median Predictive Cost of Error with an Asymmetric Cost Function
Journal of the Operational Research Society, 1989Summary: The problem of reducing predictive cost is considered in the case when the cost of error function is not symmetric and the optimality criterion is the minimization of the median cost of the error of prediction. Examples are given and comparisons made with the usual solution based on the minimization of the mean cost.

Minimum Cost Consensus With Quadratic Cost Functions
IEEE Transactions on Systems, Man, and Cybernetics - Part A: Systems and Humans, 2009Group consensus is an important method for making business decisions. In this paper, the consensus process is defined as a dynamic and interactive group decision process, which is coordinated by a moderator who helps the experts to gradually move their opinions closer to each other. This paper describes the importance of group consensus and the need to

On Quasi-Convexity of the Cost Function
The Scandinavian Journal of Economics, 1987For the study of duality of the cost indirect output correspondence, one needs to know when the cost function is quasi-convex in outputs. This paper gives a necessary and sufficient condition for quasi-convexity in outputs, under homotheticity of the input correspondence.

Economic Costs of Functional Dyspepsia
PharmacoEconomics, 1992Dyspepsia is defined as chronic or recurrent symptoms believed to originate in the upper gastrointestinal tract. When routine investigation results in no identifiable explanation for those symptoms patients are labelled as having functional dyspepsia. In community-based surveys, approximately 30% of the otherwise apparently healthy population report ...

Abstract This chapter studies producers who minimize the cost of producing their output. The core notion is the cost function, which is a money-metric generalization of the input-requirement function introduced Chapter 3. This analysis follows the approach developed in Chapter 5 that combines mathematical, verbal, and geometric ...

On the equivalence of cost functions in the design of circuits by cost-table
IEEE Transactions on Computers, 1990In the cost-table approach to logic design, a function is realized as a combination of functions from a table. The objective of the synthesis is to find the least-cost realization, where realization cost is the sum of the costs of the functions used plus the cost of combining them.

Physician opportunity costs in physician practice cost functions
Journal of Health Economics, 1998Estimation of cost functions for physician firms is problematic because many physicians are self-employed, and the marginal opportunity cost of physician labor is not observed. In this paper, we show how to recover marginal costs and conventional measures of economies of scale from cost functions that condition on the amount of physician labor input ...
