Optimal preventive maintenance of a production system with an intermediate buffer
In this paper we consider a model consisting of a deteriorating installation that transfers a raw material to a production unit and a buffer which has been built between the installation and theExpand

Single vehicle routing problems with a predefined customer sequence, compartmentalized load and stochastic demands
We consider the problem of finding the optimal routing of a single vehicle that delivers K different products to N customers according to a particular customer order. The demands of the customers forExpand

A semi-Markov decision algorithm for the maintenance of a production system with buffer capacity and continuous repair times
Abstract We consider a model consisting of a deteriorating installation (I) that transfers a raw material to a production unit and a buffer, which has been built between the I and the production unitExpand

A single vehicle routing problem with pickups and deliveries, continuous random demands and predefined customer order
This paper extends the results of a particular capacitated vehicle routing problem with pickups and deliveries (see Pandelis et al., 2013b) to the case in which the demands for a material that isExpand

An improved algorithm for the computation of the optimal repair/replacement policy under general repairs
We consider a system which deteriorates with age and may experience a failure at any time instant. On failure, the system may be replaced or repaired. The repair can partially reset the failureExpand

Computation of the Optimal Policy for the Control of a Compound Immigration Process through Total Catastrophes
In this paper we consider a Markov decision model introduced by Economou (2003), in which it was proved that the optimal policy in the problem of controlling a compound immigration process throughExpand

Optimal delivery of two similar products to N ordered customers with product preferences
Abstract We study a mathematical model for a specific vehicle routing problem in which a vehicle starts its route from a depot loaded with items of two similar but not identical products. The vehicleExpand

Two-compartment stochastic single vehicle routing problems with simultaneous pickups and deliveries from N ordered customers
ABSTRACTWe consider a vehicle with two compartments that starts its route from a depot and visits N ordered customers in order to deliver new (or fresh or useful) products and to collect old (or ex...
A Stochastic Single Vehicle Routing Problem with a Predefined Sequence of Customers and Collection of Two Similar Materials
We suppose that a vehicle visits N ordered customers in order to collect from them two similar but not identical materials. The actual quantity and the actual type of material that each customerExpand
Single Vehicle Routing Problem with a Predefined Customer Sequence, Stochastic Demands and Partial Satisfaction of Demands
We consider the problem of finding the optimal routing of a single vehicle that starts its route from a depot and delivers a product to N customers that are served according to a particular sequence.Expand
