Problems of unemployment
Havlová, Irena ; Soušková, Milena (advisor) ; Spirit, Michal (referee)
The aim of this thesis is to explore the area of unemployment and see how the unemployment rate has been affected by legislative changes in recent years. The first part deals with unemployment in general, describes the problems most vulnerable groups in the labor market have to face, illustrates the progress of the unemployment rate, but mostly relates to new legislation adopted in recent years, particularly changes in the Employment Act. The second part is focused on the newly established institution of public service. It deals not only with its own legislation, but also alludes to the practical problems that appeared after the introduction of public services. And for comparison, I also describe solutions from abroad and possible suggestions for improvement.

Crew Scheduling Problem: Application in Fast Food Chains
Havlová, Irena ; Zouhar, Jan (advisor) ; Kořenář, Václav (referee)
Crew scheduling is very important, especially in continuous operating environments running 24 hours a day, 7 days a week, more so if the demand for staff is varying over each hour of the day. This thesis focuses on staff optimization in a fast food chain where special conditions for scheduling like flexible starting-times and shift lengths or heterogeneous crew are present. Two new models based on a mixed integer programming approach were designed, dealing with data from a particular restaurant with the aim of improving schedules and saving time spent on the creation of those schedules. At the end of the thesis the empiric schedules and results obtained are compared and the computational efficiency of both models is discussed.

The reasons for inefficiency of public procurement
Havlová, Irena ; Štěpánek, Petr (advisor) ; Vršecký, Radek (referee)
The aim of this thesis is to explore the area of public procurement and to identify ways by which the inefficiency is caused. The work is based on the assumption that the procurement inefficiency exists and tries to uncover it by examining selected passages of the Law on Public Procurement. The first part deals with public procurement in general and the relevant legislation, the second part deals with the most problematic areas of the Law on Public Procurement which are demonstrated by practical examples and includes suggestions for possible improvement.

An Application of Travelling Salesman Problem for a Delivery Transportation
Havlová, Irena ; Skočdopolová, Veronika (advisor) ; Kuncová, Martina (referee)
Optimal route or the most suitable configuration finding occurs in different areas of human activities as science, engineering or business. In mathematics these problems are usually assigned to Travelling Salesman Problem (TSP) and its modifications. This thesis is devoted to finding a solution of TSP using a linear model and some simpler heuristics such as Method of the Closest Neighbour. The practical part of the thesis shows usage of TSP for delivery transportation of warranty orders in a part of a wholesale network, including a solution of route divided into more than one cycle. Upon obtained results some financial comparison of the present and potential situation is given.
