## 1 Introduction
Through the model's application, it became evident that the optimal solution involves adopting an alternative featuring a pneumatic conveyor. The physical and chemical characteristics of cement, including unit type, granulation, environmental dusting, abrasiveness, and susceptibility to moisture, are crucial factors influencing handling technology selection. As cement is a bulk material, identifying handling technologies that are suitable for this kind of material and in accordance with the specified characteristics is necessary. The following paragraphs provide an overview of relevant research on bulk material handling technology selection. This is followed by an analysis of potential technologies and selecting the best one based on defined criteria, a challenge commonly addressed in the literature using the MCDM method [19; 20; 21]. The combined methods used in this paper to solve the defined problem are outlined below. The problem of selecting material handling technologies is widespread and represented in almost all industrial and production systems. Unit loads and bulk materials are handled in these systems. Special attention is drawn to the handling of bulk materials, and it can be inferred from the existing literature that there is room for improvement in research on this topic. According to the reviewed literature, different conveyor technologies are most often used to handle bulk materials. The use of engaged conveyors for the handling of bulk goods is justified due to their technical and operational characteristics. [PERSON] et al. [19] solved the problem of selecting a conveyor for handling fodder within a production facility. Fodder is categorized as bulk material, and for its handling, they considered the use of belts, chains, rollers, and gravity conveyors. [PERSON] and [PERSON] [20] optimized the handling of bulk materials, analyzing the handling of soil, clay, gravel, etc. They considered the deployment of excavators and backhoes. [PERSON] and [PERSON] [21] solved the problem of selecting a technology for handling bulk materials. They compared pneumatic, roller, belt, and gravity conveyors. [PERSON] et al. [22] dealt with the selection of conveyors for a flexible production system. They considered and analyzed four different types of conveyors. [PERSON] and [PERSON] [23] considered four types of conveyors and selected one of them. They observed the deployment of conveyors in the production system for handling bulk goods, smaller boxes, and mini-load units. [PERSON] [3] and [PERSON] [24] selected a conveyor that adhered the needs of handling materials in mining. They considered the deployment of belt, chain, and conveyor scrapers. [PERSON] et al. [25] performed a comparative analysis of different types of belt conveyors. The analysis aimed to select the best type of belt conveyor for handling bulk materials in production activities. Based on the reviewed literature, it can be concluded that technologies based on conveyors are most often engaged in the process of handling bulk material. Various types of conveyors are engaged, such as belt, pneumatic, gravity, and more. Consequently, for the cement handling process, research should be directed toward the selection of conveyor technology. Through an analysis, it is necessary to select the type of conveyor that best matches the characteristics of the cement and the data from the specific case study. Numerous methodologies and tools exist for addressing the challenge of selecting appropriate material handling technologies. Within the existing body of research, authors have employed diverse approaches, such as heuristics, metaheuristics, simulations, mathematical programming, and multi-objective decision making (MADM) and MCDM techniques. In recent years, MCDM methods have gained prominence for tackling such problems.
