The diploma thesis analyzes contemporary trends and provides overview of key elements within purchasing processes in companies recommended by foreign professional studies. Autor of the thesis analyzes purchasing process in 4 manufacturing companies - GE Aviation Czech, s.r.o., Faurecia Exhaust Systems, s.r.o., Continental Automotive Czech Republic, s.r.o., Brandýs nad Labem a Doosan Bobcat Manufacturing, s.r.o. Given the recommendations by foreign studies the thesis provides suggestions on their application in manufacturing companies taking into account the specific conditions in the four companies.

This study was developed to determine whether buyers expect suppliers with whom they have strong relationships to take preventative action if external events threaten to disrupt planned transactions. The alternative is that buyers perceive the relationships to be limited to contract obligations. This dissertation employed a quantitative study design to examine the buyer's view of buyer-supplier relational capital as a tool for risk reduction in the supply chain. The study is an extension of the work linking social capital, risk management, and inter-organizational network theory. The research population was a sample of 612 U.S. buyers managing global supply chains. The results were analyzed with factor analysis to evaluate the contribution of relational expectations, contract use, and organizational risk practices on the perceived risk reduction actions of the supplier. The relationships between the identified factors were determined through the development of a path model using partial least squares analysis. The data analysis suggests that the buyer does perceive relational capital to bring about specific risk prevention action from the supplier. More importantly, buyers include in their relational expectations of the supplier the reduction of any perceived supply chain risk that could impact the buying organization. The study also reveals the widespread use of preferred supplier relationships to handle the acquisition of critical goods and services. The study adds to the supply chain body of knowledge by expanding the known scope of buyer-supplier relational expectations. The work validates previous research by Ellis & Shockley (2010), which asserts that collaborative relationships lower a firm's risk profile. It also provides empirical evidence for network theories such as the study by DeWever, Vandenbempt & Martin (2005), who find that relational capital is a potential source of assistance during times of trouble.

The purpose of this paper was to investigate the overview of sustainability in apparel manufacturing industry and why environmentally and socially sustainable practices are being adopted by developing country suppliers and how the implementation process is both hindered and enabled. Currently the worldwide survival of the apparel industry is the main significant question. The most spoken about issue is for the sustainability of fashion in the world. Many organizations and fashion-conscious personalities have come forward to uphold the further extension of tomorrow 's good environment campaign, but the garments and textile industries in Bangladesh are far beyond this awareness, posing a risk of losing the world market. On the other hand, one of the key concepts for humanity and sustainability point of view is fashion for the moral or ethical issues. It is high time specific sustainability strategies and approaches were implemented. Improvements in social and environmental support migrant employees, help manufacturers establish longer-term partnerships with transnational companies and lead to production. The Bangladeshi garments industries are currently facing great challenges in terms of the working environment. Fire injuries are frequent in garments factories and the recent collapse of buildings poses a significant danger to their future.  In addition, the workers earn the world's lowest salaries which make them unsatisfied, sometimes causing clashes and violence during low-wage protests. This paper has looked at the work environment, fire and health problems facing Bangladesh's garments industry and proposes major steps to strengthen the environment and sustainability.

The diploma thesis deals with the study of the supply process in the chosen company, which mainly deals with the purchase and sale of cleaning machines and equipment. The thesis presents a proposal to improve the Supply Chain, with an emphasis on streamlining traffic, while at the same time making it possible to streamline customer service by designing a website. The work is divided into three main parts. The first part includes all the theoretical starting points, from which the analytical part starts. This part is mainly consists of analyzing the state of the company by using appropriate methods. On the basis of the shortcomings identified, the third part discusses suggestions for improving the processes that will contribute to their improvement, increasing the competitiveness of the company and increasing the value for the customer.

This Master’s thesis presents a design of models which are intended for evaluation of Braintrast’s suppliers. Based on the evaluation, there is selected the most optimal supplier according to parameters. The model uses fuzzy logic theory to support decision making. The solution is designed in programs MATLAB and MS Excel.

Bad cooperation with suppliers can involve serious threat of company run. This thesis deals with change of supplier subjects and switch-over a technology provided by new suppliers.

Fuzzy logic is a complex tool for support for decision-making in various arrays of use. This thesis should analyze existing solutions in selected decision processes in companies and to bring more effective ways of decision-making using fuzzy logic in consequence.

The diploma thesis „The Benefits of Optimizing Inventory Management in Relation to the Installation“ streamlining the production process by optimizing the supply of production. The basis of this work is the analysis of the company with respect to supply the selected installation type. The work conatins a proposed solution, based on analysis of business results and theoretical knowledge.

This master’s thesis deals with design of models which allows to evaluate different plastic windows suppliers. Suggested model uses fuzzy logic to evaluate suppliers and is used as a support for decision-making. With small modifications, the model can be also used repeatedly. The solution itself is designed by MATLAB and MS Excel programs.

This diploma thesis deals with the design of fuzzy model for decision among suppliers of the metallurgical material for the firm VÚEZ, a.s. Levice. It describes methods and processes of a model creating. The goal is to make a decision-making system that helps a firm to make decisions among suppliers more effective that will be usable in real world and is based on firm’s requests.
