[EN] In recent years, a large number of heuristics have been proposed for the minimization of the total or mean flowtime/completion time of the well-known permutation flowshop scheduling problem. Although some literature ...
[EN] Automated Storage and Retrieval Systems (AS/RS) have become vital in today¿s distribution and production
environments, however it remains necessary to equip them with more efficient operational control
policies. ...
[EN] The permutation flowshop problem is a classic machine scheduling problem where n jobs must be processed on a set of m machines disposed in series and where each job must visit all machines in the same order. Many ...
[EN] This paper examines the economic optimization of reinforced concrete road frame bridges by threshold acceptance. The formulation of the problem includes 50 discrete variables: three geometrical ones, three types of ...

[EN] The solution of fleet assignment problems is one of the core points in the management of a car-rental company. These problems arise from the restrictions imposed by the acceptance of reservations of the customers and ...
In the no-idle flowshop, machines cannot be idle after finishing one job and before starting the next one.
Therefore, start times of jobs must be delayed to guarantee this constraint. In practice machines show
this ...

[EN] The mixed no-wait flowshop problem with both wait and no-wait constraints has many potential real-life applications. The problem can be regarded as a generalization of the traditional permutation flowshop and the ...

Many planning domains have to deal with temporal features that can be expressed
using durations that are associated to actions. Unfortunately, the conservative model of
actions used in many existing temporal planners is ...

This paper analyzes the solvability of a railway network design problem and its robust version. These problems are modeled as integer linear programming problems with binary variables, and their solutions provide topological ...
[EN] Recently, in the field of project scheduling problems the concept of partially renewable resources has been introduced. Theoretically, it is a generalization of both renewable and non-renewable resources. From an ...
[EN] In this paper, we study the unrelated parallel machine scheduling problem with one scarce additional resource to minimise the maximum completion time of the jobs or makespan. Several heuristics are proposed following ...
Task scheduling has a significant impact on the performance of the MapReduce computing
framework. In this paper, a scheduling problem of periodical batch jobs with makespan minimization
is considered. The problem is ...
