“…To do this, businesses need to make important decisions. A tool helpful in making decisions related to production planning can be a simulation model [2,3,4] which, based on real data from the process, allows for the verification of decisions before entering them into the real system [5,6].In the literature, you can find examples of modelling e-business processes [7,8] and the extension of models to supply chains [9], as well as descriptions of the benefits of using a new methodological approach to develop static and dynamic simulation models [10,11]. In [12] the simulation was used to test the real system model and see the results of the optimization of the production system in concrete conditions, which bring specific improvements in concrete case -increased pieces of final product, better utilization of production time and reduction of storage times to minimum.…”

Problems on the world market, related to delays in supply chains, have forced enterprises to adopt a more fl exible approach in the production processes of the off ered products. In order to meet customer needs, companies can often look for alternative supply chains, as well as take over the production of key components necessary to maintain business continuity. Therefore, companies have to make important decisions in the context of management. A simulation model may be a tool helpful in making decisions related to production planning, which, based on the actual data collected from the process, allows for the verifi cation of decisions before entering them into the real system. The motivation to conduct the research was the search for answers: How entrepreneurs, while maintaining profi tability, can ensure the continuity of production processes by searching for alternative production methods. The article considers a comparison of two production processes for the production of a shield type product: classic production -on a lathe and hybrid production using the SLM method and machining only technologically signifi cant surfaces on a lathe. The main goal of the research is to compare two production processes: classic and hybrid in terms of effi ciency, energy effi ciency and production costs. The research takes into account the use of diff erent laser powers and the possibility of incremental production of several products at the same time. In order to achieve the assumed goal, a simulation model was used to carry out the research, which was developed on the basis of preliminary experimental studies. A series of simulations were performed, taking into account the variability criteria, and then the effi ciency, energy effi ciency and profi tability of using alternative production methods were analysed. The purpose of the article is comparison of two production processes, classic and hybrid, in terms of effi ciency, production costs and electricity consumption.

“…Also, it provides a novel application of morphological analysis to business model innovation to create a generic business model for IoT applications in emerging markets. According to the concept of Industry 4.0, among others Martinez-Hernandez et al [10] presents a conceptual model for characterizing localized production systems, and Hulkó et al [11] describes virtual software environments for technological process control. The literature describes also problems related to the design of the synthesis of future mechatronic robotic objects, the so-called e-facilities for product life cycle analysis [12].…”

In the era of Industry 4.0, the digitization of production processes is one of the important elements contributing to the reduction of uncertainty related to the implementation of new production methods. The worldwide epidemic situation and its constraints have resulted in supply chain continuity problems. These problems make enterprises look for the possibility of producing products that they need at the moment and which they cannot obtain from the market. In special cases, this may also apply to spare parts necessary to maintain the continuity of production. The main reason for research on comparing production processes is meeting the challenges related to the pandemic situation and problems in maintaining timeliness, fl exibility, and continuity of the supply chain. The fi rst stage of the research was to visualize the course of the process and determine the lead times for both production methods. For further analysis, a digital process model was used to compare the hybrid and the classical method to check the viability of the interchangeability of methods for the production process of the fl ange part. The interchangeability of production methods was dictated by problems related to the supply of components for the execution of orders. The article simulates the model for unit and small-lot production in batches of 10 and 100 pieces, considering such aspects as: order completion time, energy consumption of the process, production costs, taking into account the classic and hybrid methods. The conducted research was aimed at determining the profi tability of the production of fl ange-type products by means of classical processing and hybrid and checking the interchangeability of production methods in accordance with quality requirements as well as reducing uncertainty with the implementation of new production systems in changing market conditions. The simulations show that the use of hybrid production is recommended for unit production. In the case of small-lot production, already with 10 items, production in the traditional process is 21% cheaper, and for the production of 100 items, the cost of traditional production is reduced by 33% compared to hybrid production.

“…It depends on the character of change in the measured temperature and on the flow rate of a liquid or gas whose temperatures must be measured. Therefore, one and the same thermal receiver depending on the measurement conditions can be interpreted as MT with lumped parameters or MT with distributed parameters [11][12][13].…”
