The basic deterministic stationary inventory problem, in which backorders are allowed, is analyzed. Instead of considering the backorder cost to be a cost per unit and per time, we also suppose the presence of a fixed backorder cost per unit. The latter generates a supplementary dependence of...

We present an effective scheduling heuristic for realistic production planning in a petrochemical blending plant? The considered model takes into account orders spanning a multi-product portfolio with multiple bills of materials per product, that need to be scheduled on shared production...

We consider a selective vehicle routing problem, in which customers belonging to di?fferent partners in a logistic coalition are served in a single logistic operation with multiple vehicles. Each partner determines a cost of non-delivery (CND) for each of its customers, and a central algorithm...

This paper proposes a variant of the well-known capacitated vehicle routing problem that models the routing of vehicles in the cash-in-transit industry by introducing a risk constraint. In the Risk-constrained Cash-in-Transit Vehicle Routing Problem (RCTVRP), the risk of being robbed, which is...

In this paper we defi?ne a new problem, the aim of which is to fi?nd a set of k dissimilar alternative solutions for a vehicle routing problem (VRP) on a single instance. ?This problem has several practical applications in the cash-in-transit sector and in the transportation of hazardous...

This paper proposes a variant of the well-known capacitated vehicle routing problem that models the problem of routing vehicles in the cash-in-transit industry by introducing a risk constraint. In this problem, which is called the risk-constrained cash-in-transit vehicle routing problem...

Existing literature on routing of school buses has focused mainly on building intricate models that attempt to capture as many real-life constraints and objectives as possible. In contrast, the focus of this paper is on understanding the joint problem of bus route generation and bus stop...

In this paper, we present a variant of the vehicle routing problem (VRP) to increase security in the cash-in-transit sector. A speci?c index is used to quantify the exposure of a vehicle to the risk of being robbed along its route. In addition, the problem is subjected to a traditional capacity...

In this paper, we propose a new metaheuristic to solve the Risk constrained Cash-in-Transit Vehicle Routing Problem (rctvrp). The rctvrp is a variant of the well-known capacitated vehicle routing problem and models the problem of routing vehicles in the cash-in-transit sector. In the rctvrp, the...

This paper introduces progressive multi-objective optimization (PMOO), a novel technique to include the decision maker's preferences into the multi-objective optimization process. PMOO integrates a well-known method for multi-criteria decision making (PROMETHEE) into a simple multi-objective...
