In this paper we investigate the minimization process of the exact cost function for a continuous review (Q,R) inventory model with non-negative reorder point and fixed lead-time. Backorders are allowed and the unit shortage cost is used to determine the expected annual shortage cost. Provided...

Färe and Mitchell(1992) have shown that cost functions for a multi-output firmobey a particular output-scaling law if and only if the underlyingproduction technology is ray-homothetic. Multi-output firms,however, frequently change their output mix in addition to theirscale. Therefore, it is...

This paper proposes a multiple-output Symmetric Generalised McFadden (SGM) cost function, incorporating both exogenous and endogenous technological change. Whilst exogenous technological change is captured by the usual time trend, endogenous or price-induced technological change is cast within a...

Cost functions as the foundation of managerial decision making usually assume a linear cost function with fixed and variable costs. The latter are dominantly regarded as being identical for increasing and for decreasing activity levels. However, empirical research shows that the decline in costs...

The aim of this paper is the establishment and validation of cost functions for the various assets of sewer systems, namely gravity and raising pipes, manholes and pumping-stations. Costs are defined as a function of the main physical characteristics of the assets, such as, the pipe material and...

A method to carry out a Reliability-Based Optimization (RBO) of especially nonlinear structural systems is introduced. Statistical uncertainties involving both structural and loading properties are considered. The concept is based on the separation of structural reliability analyses and the...

It 15 difficult to obtain c1osed-fonn solutions for input demand equations that are conducive to econometric estimation and policy analysis when the production function IS unknown Developments In the theory of duality facilitate obtaining such equations This article provides three examples of...

En el presente trabajo se calcula el valor de la cuota para in grupo de productores lecherose en Asturias, Para ello se estima una funcion de costes variables usando datos de panel de 71 explotaciones lechuras en el periodo 1993-1998. Una caracteristica improtante del modelo empleado es que...

Flexibility can be considered as a crucial factor of competitive advantage, especially under conditions of dynamically changing environments. Based on the classical microeconomic definition of flexibility, as introduced by Stigler, and some recent concepts developed in the production economics,...
