Design of a new production line
Hejl, Martin ; Jurová, Marie (referee) ; Juřica, Pavel (advisor)
This diploma thesis deals with the project of implementing a production line in a selected company dealing with the recycling of plastic waste and the production of rPET flakes as a secondary raw material for the production of plastic products. First, it deals with the description of the current state and the production process in the company, including the layout of the equipment, and then defines the requirements for the project by the management of the company and individual shareholders of the company. Defining the requirements for the project and at the same time the method of obtaining key information took place on the basis of in-depth interviews with the interested parties of this project, while a pilot design of the layout of the machinery was created, including a description of the technology and a flowchart of the required production process. The main content of the design part is the creation of a proposal for a possible implementation of the production line using a network diagram using the PERT method, which indicates that the duration of the project was calculated to be 106.6 days. Together with the network diagram of the project, an analysis and proposals for managing the risks of this project were prepared. At the end of the draft chapter, a financial analysis of the project's payback period was carried out, as the condition of a payback period of 3-5 years must be met in order for the project to be approved by the shareholders, which this project fulfilled in all three expected progress scenarios.
