EPQ model with depreciation cost and process quality cost as continuous functions of time

Extensive research has been devoted to economic production quantity (EPQ) problem. However, little atten-tion has been paid to problems where depreciation cost and process quality cost must be considered, simulta-neously. In this paper, we consider the economic production quantity model of minimizing the annual total cost subject to depreciation cost and process quality cost, where depreciation...

A Partially Observable Markovian Maintenance Process with Continuous Cost Functions

In this paper a two-state Markovian maintenance process where the true state is unknown will be considered. The operating cost per period is a continuous random variable which depends on the state of the process. If investigation cost is incurred at the beginning of any period, the system wit I be returned to the "in-control" state instantaneously. This problem is solved using the average crite...

Calculus of Cost Functions

We study algebraic properties of cost functions. We give an application: building sets close to being Turing complete.

Convex Cost Functions

The concept of Support Vector Regression is extended to a more general class of convex cost functions. It is shown how the resulting convex constrained optimization problems can be eeciently solved by a Primal{Dual Interior Point path following method. Both computational feasibility and improvement of estimation is demonstrated in the experiments.
