Control analysis of transition times in metabolic systems.

Meléndez-Hevia, E, Torres, N V, Sicilia, J, Kacser, H

The transition time, tau, of a metabolic system is defined as the ratio of the metabolite concentrations in the system, sigma, to the steady-state flux, J. Its value reflects a temporal...

Control analysis of transit time for free and enzyme-bound metabolites: physiological and evolutionary significance of metabolic response times.

Cascante, M, Meléndez-Hevia, E, Kholodenko, B, Sicilia, J, Kacser, H

Control analysis of transit time, defined as tau = delta/J, has previously been considered with the constraint of low enzyme concentrations compared with free pools of metabolites [Meléndez-Hevia,...

Analysis and characterization of transition states in metabolic systems. Transition times and the passivity of the output flux.

Torres, N V, Sicilia, J, Meléndez-Hevia, E

In this paper we study the transitions between steady states in metabolic systems. In order to deal with this task we divided the total metabolite concentration at steady state, sigma, into two new...

AN INVENTORY SYSTEM WITH PARTIAL BACKLOGGING MODELED ACCORDING TO A LINEAR FUNCTION

J. SICILIA, J. GARCÃA-LAGUNA

In this paper, we study an inventory system with partial backlogging, in which the backlogging rate is a continuous and nonincreasing two piece function. The total shortage cost includes three...

An efficient approach for solving the lot-sizing problem with time-varying storage capacities

Gutiérrez, J., Sedeí±o-Noda, A., Colebrook, M., Sicilia, J.

We address the dynamic lot size problem assuming time-varying storage capacities. The planning horizon is divided into T periods and stockouts are not allowed. Moreover, for each period, we consider...
