Distribution planning is crucial for most companies since goods are rarely produced and consumed at the same place. Distribution costs, in addition, can be an important component of the final cost of the goods. In this paper , we study a VRP variant inspired on a real case of a large distribution company. In particular, we consider a VRP with a het...

Purpose – The purpose of this paper is to present a problem-based learning (PBL) activity that uses a decision support system (DSS) to teach one of the most fundamental topics in distribution planning: vehicle routing. Design/methodology/approach – The authors describe their teaching experience in a logistics and supply chain management (LSCM) cou...

Iterated Local Search (ILS) is one of the most popular single-solution-based metaheuristics. ILS is recognized by many authors as a relatively simple yet efficient framework able to deal with complex combinatorial optimization problems (COPs). ILS-based algorithms have been successfully applied to provide near-optimal solutions to different COPs in...

Blood samples are usually collected daily from different collection points, such hospitals and health centers, and transported to a core laboratory for testing. This paper presents a project to improve the collection routes of two of the largest clinical laboratories in Spain. These routes must be designed in a cost-efficient manner while satisfyin...
Article
To understand whether retailers should consider consumer returns when merchandising, we study how the optimal assortment of a retailer is influenced by its return policy. The retailer selects its assortment from an exogenous set of horizontally differentiated products. Consumers make purchase and keep/return decisions in nested multinomial logit fa...

Article
Randomized heuristics are widely used to solve large scale combinatorial optimization problems. Among the plethora of randomized heuristics, this paper reviews those that contain biased-randomized procedures (BRPs). A BRP is a procedure to select the next constructive ‘movement’ from a list of candidates in which their elements have different proba...
Article
Recent studies suggest that transfusion of old red blood cell (RBC)s, mainly those close to the 42-day maximum shelf life (MSL), is associated with increased morbi-mortality. Although there is no formal proof supporting a causal relationship, the precautionary principle asks for corrective interventions whenever they do not bring about other risks...

The Vehicle Routing Problem is one of the most studied problems in the Operations Research literature, and is also one of the most applied problems in several industries from retailing to health care. In this paper we present a new version of the Vehicle Routing Problem, the Heterogeneous Fixed Fleet Vehicle Routing Problem with Multi-trips and max...

In this paper we present a Vehicle Routing Problem (VRP) faced by a large distribution company in the Northeast of Spain. The company distributes products from its central facilities to a chain of around 400 stores all over the country. One of the peculiarities of the VRP of this company –which is common among real-life VRPs– is the presence of a h...

This paper presents several experiences regarding Operations Research (OR) and Simulation education activities in three master programs, each of them offered at a different university. The paper discusses the importance of teaching these contents in most managerial and engineering masters. After a brief overview of existing related work, the paper...

This work focuses on the Total Weighted Tardiness Job-Shop Schedul-ing Problem. In this problem, each job consists of a set of tasks that must be processed on a given set of machines for uninterrupted and predetermined time. Each job has a due date and a penalty associated with the delay in comple-tion time. The objective is to minimize the total w...

This paper has its focus on the vehicle routing problem (VRP) with he-terogeneous fleet multiple trips. Given the combinatorial nature of the problem, which practically precludes the exclusive use of mathematical programming methods, said exact, solution of real cases is typically done through heuristic methods. The real vehicle routing problems in...

La problemática del enrutamiento de vehículos cobra cada vez más importancia en el plano empresarial y estatal. Esta área de estudio ha experimentado grandes avances teóricos, pero se ha mantenido a cierta distancia de la práctica. La mejora en las técnicas para obtener soluciones factibles y de calidad está permitiendo aplicar resultados teóricos...

Should retailers take product returns into account when choosing their assortments? And, when doing so, should they consider assortment selection as a popularity contest – by carrying products that they think will be popular among consumers? Or, is there ever a case for carrying eccentric products – those that are least likely to be purchased by a...
