Optimization and Analysis of the Layout of Access Points of a Storehouse

Cílem této bakalářské práce je optimálně rozvrhnout přístupové body skladu, takzvané brány, za podmínek zadaných firmou. Vedlejším cílem je pak ukázat využití metod operačního výzkumu na praktickém příkladu a předvést tak zadavatelské firmě nejen optimalizaci výsledku, ale také postupu řešení problematiky. První kapitola je věnována představení fungování zadavatelské firmy a vysvětlení zadané problematiky. Závěr první kapitoly se pak zabývá metodologií a softwarem, použitými v této práci. Na začátku druhé kapitoly jsou popsána zdrojová data poskytnutá zadavatelskou firmou a jejich následná úprava do podoby vhodné pro zpracování pomocí matematického modelu. Další část této kapitoly je věnována formulaci matematických modelů a následné interpretaci jejich výsledků. Poslední kapitola se pak zabývá kvantifikací rozdílů řešení problematiky pomocí matematického modelu a intuitivního řešení zadavatelské firmy. Toto srovnání je založeno na rozdílu v ujeté vzdálenosti a finančním ohodnocení pracovníků.The primary goal of this bachelor's thesis is to find the optimal layout of access points, the so called gates, of a distribution centre, while complying with the company requirements. The secondary goal of this thesis is to show the responsible workers in the company the application of operation research on an example that is put into practise and in this way to show them not only the efficiency of the result, but also of the process of solving the problem with the help of operation research. The first chapter is dedicated to introducing the processes of the company and the given problem. The end of this chapter then deals with the methodology and software which are used in the work. At the beginning of the second chapter the data sets are described. This chapter also covers the adaptation of the data into a suitable form for its further use by a mathematical model. The following part of this chapter then deals with the formulation of mathematical models and the interpretation of the results of those models. The final chapter concerns itself with the quantification of the differences between the solutions of the problem when using the mathematical models or the original intuitive solution of the company. The chapter compares the solutions with the help of driven distances and financial evaluation of the workers

Inventory routing problem

Inventory routing problem is a mathematical method of operations research, consisting of two basic models (vehicle routing problem and inventory allocation). The goal of this master thesis is to introduce the reader to what exactly inventory routing is, why and how it was created and how it evolved over the course of years. Also, some examples of actual real-life applications of the problem will be shown together with the results of their implementation. Researches and papers of the last almost 40 years, written by experts on the subject are used as the source for this master thesis. From these works, the summarizing thesis was written, putting together the most important knowledge on how to solve the problem. Its contribution is not just the explanation of the theory and its development, but also introduction of some real applications of Inventory routing. Applicability of the model and its positive results in the form of cost savings is shown on real examples
