Within the complex domain of production management, the careful choice of a highly effective scheduling policy can significantly impact the timely completion of deliveries. This study explores a practical example undertaken at a manufacturing company in Canada, employing the sophisticated features of the AnyLogic simulation program to analyze and evaluate two commonly used production policies: Shortest Production Time (SPT) and Earliest Due Time (EDT). The main aim is to determine which of these tactics consistently results in greater rates of prompt deliveries, a crucial aspect for both customer happiness and operational efficiency. In order to ascertain the credibility and resilience of the simulation results, a comprehensive statistical analysis was performed utilizing the Minitab software, with particular emphasis on the main effect plots. The initial findings suggest notable disparities in performance indicators between the two policies, with one policy exhibiting a distinct advantage in terms of its adherence to delivery timetables. This study not only presents a quantitative evaluation of SPT and EDT policies, but also gives valuable insights that might assist decision-makers in the manufacturing sector in choosing the most suitable policy to ensure prompt delivery.

This work is devoted to researching technological equipment for homogenization. It has been found that the devices for obtaining finely dispersed emulsions, which exist today, need to be modernized to reduce the energy indicators of homogenization and increase the quality characteristics of the finished provision. As a result of the study, it has been established that the pulsating homogenizer allows for obtaining high homogeneity of the dispersed phase with low energy costs for the process. Although this study was conducted on a milk emulsion, the results can be used for other binary dispersion emulsions. The emulsion is dispersed in the pulsating homogenizer using the emulsion velocity gradient caused by the pulsating vibration of the shock piston. To calculate the hydrodynamic parameters of milk emulsion pumping speed, computermodeling was performed using software that allows for effective analysis of the homogenization process and has a special software package for this purpose - Ansys Workbench. With the help of computermodeling and calculations in ANSYS Workbench, the quality of homogenization due to processing milk in the pulsation homogenizer was determined. Experimental studies have shown that the average diameter of milk fat globules after homogenization in the pulsation homogenizer is 0.8 mu m, which fully meets today's requirements.

Wire Arc Directed Energy Deposition (DED) is a subcategory of the DED Additive Manufacturing (AM) technology that is rapidly gaining popularity due to its potential to produce large-scale, complex metal parts while maintaining a lower cost and higher productivity and sustainability when compared with other AM technologies. Additionally, Wire Arc DED permits a high level of customization in terms of designing and implementing manufacturing systems. However, there are still important quality issues hindering wire Arc DED, along with limited simulation approaches that offer the necessary practicality, from an industrial perspective, to support the design of wire Arc DED manufacturing systems. Towards this goal, aiming to the minimization of the experimental cost and time, a simulation approach of wire arc DED is presented in this study. The model has been developed in COMSOL Multiphysics, allowing for a high level of customization, while maintaining practicality and ease of use, both in terms of implementation as well as computational cost. The modeling approach is analyzed, followed by the implementation of the methodology in a case study. Preliminary results are presented, discussed, and accompanied by suggestions for future research.
