Increasing the efficiency of logistics in warehouse using the combination of simple optimization methods

The paper focuses on increasing the efficiency of logistics process in warehouse. Today’s trend is to use simulation tools. To obtain effective solutions exist various optimization methods, optimization algorithms and heuristics. The presented experiment uses the combination of two simple optimization methods for searching the effective solution in reasonable time. The Random solutions algorithm and the All combinations algorithm are used together. Random solutions algorithm generates random combinations and can help indicate how solutions will vary, by giving a picture of the shape of the entire solution space for a scenario. All combinations algorithm is a method, which runs all constrained combinations. If sufficient time is available, this method guarantees that the optimal result will be found. An estimate of the time to be taken can be obtained in advance. This concrete two algorithms demonstration is a high quality and fast way to achieve effective (optimal) results in a short time. The Witness simulation environment is used for the experiments. © 2018, Springer International Publishing AG.ERDF, European Regional Development FundMinistry of Education, Youth and Sports of the Czech Republic within the National Sustainability Programme [LO1303 (MSMT-7778/2014)]; European Regional Development Fund [CZ.1.05/2.1.00/03.0089]; Internal Grant Agency of Tomas Bata University [IGA/FAI/2017/003
