In this paper, the waste collection problem (WCP) of a city in the south of Spain is addressed as a multiobjective routing problem that considers three objectives. From the company's perspective, the minimization of the travel cost is desired as well as that of the total number of vehicles. Additionally, from the employee's point of view, a set of balanced routes is also sought. Four variants of a multiobjective hybrid algorithm are proposed. Specifically, a GRASP (greedy randomized adaptive search procedure) with a VND (variable neighborhood descent) is combined. The best GRASP–VND algorithm found is applied in order to solve the real‐world WCP of a city in the south of Spain.

“…Also in the application considered by López‐Sánchez et al. (), the duration of the longest route was used as the measure of quality of a solution. They named this variant as balanced open vehicle routing problem since minimizing the maximum route duration can also be viewed as a measure of route balancing.…”

In this paper, the MinMax‐COVRP (where COVRP is capacitated open vehicle routing problem) is considered as a variation of the COVRP where the objective is to minimize the duration of the longest route. For the purpose of producing high‐quality solutions, elements from the fields of mathematical programming and metaheuristics are combined, resulting in a matheuristic for solving the MinMax‐COVRP. The matheuristic benefits from the diversification produced by a metaheuristic and the intensification from mixed‐integer linear programming (MILP). The initial solution provided by a multistart heuristic is used to seed and accelerate the MILP in which a local branching framework and the separation of k‐path inequalities are suitably combined. Computational experience shows promising results not only improving the initial solution provided by the multistart algorithm, but also ensuring optimality for most of the small‐ and medium‐sized instances.

“…In the literature, vehicle routing problems can be structured differently according to various constraints, such as capacitated VRP [120][121][122][123][124][125][126], the VRP with heterogeneous fleet of vehicles [127], open VRP [128][129][130][131], VRP with time windows [132][133][134][135][136][137][138], VPR with both pick-up and delivery [139][140][141][142][143][144], location routing problem [145][146][147], period VRP [148][149][150][151], multidepot VRP [152][153][154][155][156], VRP with backhaul [157][158][159], inventory routing problem [160][161][162][163], dynamic VRP [164], or the mixture [165][166]…”

Over the past decades, optimization in operations management has grown ever more popular not only in the academic literature but also in practice. However, the problems have varied a lot, and few literature reviews have provided an overview of the models and algorithms that are applied to the optimization in operations management. In this paper, we first classify crucial optimization areas of operations management from the process point of view and then analyze the current status and trends of the studies in those areas. The purpose of this study is to give an overview of optimization modelling and resolution approaches, which are applied to operations management.
