Reviewer: doc. Ing. Jakub Arm, Ph.D.
This thesis deals with the design and implementation of a Testbed 4.0 control model based on discrete-event systems (DES) using the decentralized negotiation mechanism Contract Net Protocol (CNP). The model is developed in the MATLAB Simulink environment with the SimEvents extension and is intended for the simulation of a manufacturing system composed of autonomous cells communicating through a bidding algorithm. The model includes the implementation of distributed production planning, dynamic task allocation, and communication between individual system modules. The thesis also focuses on the design of a simulation visualization system enabling the monitoring of communication between cells, system states, and selected operational metrics such as cycle time, throughput, resource utilization, queue lengths, and work in progress (WIP). Furthermore, several configuration and operational scenarios reflecting possible layouts of the Testbed 4.0 system are defined. Based on the performed simulations, the effects of system configuration changes on efficiency and behavior under decentralized control conditions are evaluated.

Process of defence
Student odprezentoval připravenou prezentaci a následně odpovídal na dva dotazy položené oponentem závěrečné práce. V následné rozpravě se komise ptala zdá dává smysl realizovat práci na nekomerčním/alternativním softwaru. Komise se ujišťovala co je cílem práce. Byla vznesena námitka na formální stránku práce. Student obhájil bakalářskou práci. Komise neměla žádné významné námitky k řešené práci. V průběhu odborné rozpravy student odpověděl na dotazy.
