The presented work relates with the purchasing management in construction. It consists of two parts. In the first part, we will focus on the theory of purchasing, then discuss the individual steps of the purchasing management and inventory management in the business. Moreover, we will bring insights from the area of suppliers - their selection and evaluation. In second, practical part, we analyze the current state of the purchasing management in selected companies. The output of attached work is a proposal for improvements and recommendations for business purchase following performed analysis.

Since the introduction of sustainable development, industries have witnessed significant sustainability challenges. Literature shows that the food industry is concerned about its need for efficient and effective management practices in dealing with perishability and the requirements for conditioned storage and transport of food products that effect the environment. Hence, the environmental part of sustainability demonstrates its significance in this industrial sector. Despite this, there has been little research into environmentally sustainable inventory management of deteriorating items. This thesis presents mathematical modelling based research for production inventory systems in perishable food supply chains. In this study, multi-objective mixed-integer linear programming models are developed to determine economically and environmentally optimal production and inventory decisions for a two-echelon supply chain. The supply chain consists of single sourcing suppliers for raw materials and a producer who operates under a make-to-stock or make-to-order strategy. The demand facing the producer is non-stationary stochastic in nature and has requirements in terms of service level and the remaining shelf life of the marketed products. Using data from the literature, numerical examples are given in order to test and analyse these models. The computational experiments show that operational adjustments in cases where emission and cost parameters were not strongly correlated with supply chain collaboration (where suppliers and a producer operate under centralised control), emissions are effectively reduced without a significant increase in cost. The findings show that assigning a high disposal cost, limit or high weight of importance to perished goods leads to appropriate reduction of expected waste in the supply chain with no major cost increase. The research has made contributions to the literature on sustainable production and inventory management; providing formal models that can be used as an aid to understanding and as a tool for planning and improving sustainable production and inventory control in supply chains involving deteriorating items, in particular with perishable food supply chains.

Introduction: Nowadays firms must focus on maintaining healthy finished goods inventory stocks in order to be able to decrease inventory costs, meet customer requirements and to obtain competitive advantage. However large decentralized manufacturing companies often face the problem of sub-optimization in inventory management in subsidiaries due to several different reasons. As a result, company loses its competitiveness. Thus, there is a need to coordinate inventory activities of subsidiaries to prevent sub-optimization. Purpose: The purpose of this thesis is to investigate whether coordination mechanisms highlighted in academic literature are used in practice on the example of manufacturing company with decentralized decision-making structure for optimization finished goods inventory stocks. Frame of reference: This research is based on theoretical framework and empirical findings. Empirical data were collected through personal interviews and retrieved from organisational documents. Methodology: The research strategy for this paper is a single case study. This strategy allows investigating topic in its real life context. The deductive approach is used for this research based on qualitative data. The major source of data collection was semi-structured interviews and the company's documents. For analysing data categorisation approach was applied. Conclusion: The study found that most of coordination mechanisms presented in scientific literature are used in practice. To achieve better results these mechanisms should be applied simultaneously and consistently since they complement each other. We also observed that coordination mechanisms indeed give positive results and are able to optimize inventory management.

In the increasingly fierce international competition today, short product life cycle has led to lead time compression and narrow profit margins. Rapid respond to customers has become the key to survival of modern enterprises. Many large corporations in Taiwan have implemented the Toyota¡¦s just-in-time (JIT) production planning approach to reduce inventory to a minimum level, keeping on hand only the amount needed in production until the next order arrives. However, most of those companies have often overlooked that the basic principal of just-in-time replenishment model is the raw materials and other purchased items should be delivered steadily by the supplier when they are needed, and meanwhile those materials from suppliers require no inspection. Nevertheless, it is very difficult to achieve those objectives of JIT Production, especially in an increased market demand. Once some of the suppliers can not meet the delivery time of raw materials and quality is also affected, it would derive lots of problems. This study is aimed to JIT replenishment models on examining firms¡¦ inventory issues. Based on the result of the analysis, it would be the reference to build up the model of quality-oriented embedding collaborative replenishment mechanism for enterprises to improve their JIT replenishment operations. This model, quality-oriented embedding collaborative replenishment model, could assist business in measuring the accurate and precise delivery time and ensuring product quality from suppliers. The research is on the basis of Taiwan optoelectronic industry to investigate the companies of the TFT-LCD panel, and the supply chains of the industry. In analyzing the main TFT-LCD panel providers, the paper will probe into TFT-LCD firms to implement the inventory management system by building the quality-oriented embedding collaborative replenishment mechanism to improve the reaction capacity of businesses, to reduce the risk of raw material quality issues, and to respond to the market rapid change. The study exerts simulation software to conduct simulation and improvement of such models, then according to the simulation results to utilize them as a reference to implementation of quality-oriented embedding collaborative replenishment model into the future operation.

In this study, hazardous waste inventory for Turkey is developed based on wastes identified as hazardous in European Waste Catalogue and Regulation on Control of Hazardous Wastes, Annex 7 Necessity of such inventory arises from importance of acquiring information on the amount of hazardous wastes generated and on their countrywide distribution for a sound hazardous waste management system for Turkey. Hazardous waste inventory is constructed by using waste generation factors obtained from literature which are coefficients that relate production with environmental emissions. Whenever possible, direct information obtained from generators was utilized. Both absolute and minor entries are covered. It is estimated that 4,940,000 &ndash / 5,110,000 t/yr of hazardous wastes are being generated in Turkey. 1,790,000 &ndash / 2,252,000 t/yr of these are classified as absolute entries and 3,146,000 &ndash / 3,160,000 t/yr of hazardous wastes are minor entries. It is observed that highest generation occurs from mining and thermal processes which involve high amounts of minor entries. Beside these industries highest generation occurs from wood preservation. Per capita hazardous waste generation is estimated as 30 &ndash / 77 kg/capita/yr which is in accordance with per capita generation range of EU. Highest hazardous waste generation occurs from Marmara Region with 527,730 t/yr followed by Aegean (524,580 t/yr), Central Anatolia (481,820 t/yr), Black Sea Region (277,850 t/yr), Mediterranean (211,580 t/yr), Southeast Anatolia (58,290 t/yr) and Eastern Anatolia (36,520 t/yr) excluding minor entries from mining industry and thermal processes. The trends in hazardous waste generation and GDP from manufacturing industry show the same trend. Contribution of regions are in the same order both in hazardous waste generation and GDP.
