“…Out of 25 combinations, six of them were selected, including the combination used in the case study (1, 2, 4, 11, 13, and 14), because they produced better results. In addition, an experiment was conducted with 11 more proposed combinations (3,5,6,7,8,9,10,12,15,16,17), only with mixer volumes and numbers that the given concrete plants do not possess. Again, the simulation was run 100 times for each combination and the mean values were calculated, yielding the costs for a total of 17 different combinations, as shown in Figs.…”

“…The transportation problem, extensively studied for years, ever since the emergence of operations research and linear programming during WW2, was used to solve the problem of transportation of products from different sources to different destinations, specifically to minimize transportation costs. Later, the vehicle routing problem (VRP), proposed by Dantzig [5], was used to optimize the route of identical vehicles from their starting point to their destination. With the development of various mathematical methods, new optimization methods for solving this problem also developed.…”

“…Thus far, there have been numerous studies about RMC production and delivery problems. Proposed solutions for these problems involve a large number of algorithms, such as genetic algorithms [12,14,18,29], heuristics, simulations [5,13,15,16,19], neural networks, fuzzy logic [31], etc. Unlike the previous studies, the present study applies a simulation based on the combination of DES and ABM methods, whereby a new model is developed that considers three concrete plants and three construction sites for simultaneous RMC supply via different truck mixer fleets.…”

Supply of Ready Mixed Concrete (RMC) is a common process of concrete works on any structure. There is often a need to supply one or more construction sites simultaneously from multiple concrete plants. This paper presents a new simulation model of RMC supply and delivery from three concrete plants to three construction sites. The model is dynamic, easily managed, and adjustable and it allows proper estimation of the cost and time required to solve the problem of RMC supply. Model verification was performed using a case study of concrete supply to construction sites in the city of Niš, Serbia. The case study is based on real parameters obtained from specific concrete plants and construction sites. The results of the simulation experiment with varying number of mixers indicate that there is a significant influence of vehicle number and volume on idling costs. Based on the model analysis in the case study, scenario 10 (minimum total idling cost is 14,09 €) is recommended as the optimal combination of truck mixers for the considered case study. The simulation results indicate that the selection of an adequate combination can significantly reduce the costs of idling, for both the mixer and the pump, which leads to minimal idling time and, consequently, to timely pouring of concrete without reducing its quality.

Quá trình điều phối hoạt động cung cấp hàng hóa để đạt yêu cầu và hiệu quả là một yêu cầu khó trong quản lý chuỗi cung ứng. Những sự thay đổi liên tục trong quá trình vận chuyển và yêu cầu cao về lượng khí thải ra môi trường là những thách thức không nhỏ cho các nhà phân phối. Nghiên cứu phát triển một thuật toán mới, lấy cảm hứng từ quá trình săn mồi của loài chó rừng vằn hông (Side-striped jackal) để tạo ra thuật toán tìm kiếm hiệu quả hơn so với các thuật toán cũ. Nghiên cứu sử dụng dụng mô phỏng sự kiện rời rạc (DES) và đưa ra các sự cố giả định để giải quyết bài toán tối ưu hóa đa mục tiêu với kì vọng chọn được phương án có tổng thời gian chờ và quãng đường di chuyển là tối ưu nhất. Kết quả được so sánh với các thuật toán cũ cho thấy tính nổi trội của thuật toán đề xuất khi đưa ra được các phương án kinh tế hơn và ít khí thải khí CO2 ra môi trường hơn. Nghiên cứu còn giải quyết được vấn đề thay đổi lộ trình đi khi xét đến các điều kiện thực tế. Qua đó, thuật toán mới giúp cho quá trình quản lý vận chuyển hàng hóa chủ động hơn và giảm thiểu phát sinh chi phí khi có những điều kiện bất lợi không mong muốn xảy ra. Từ khóa: tối ưu hóa chó rừng vằn hông; SSJ; hiệu ứng nhà kính; tối ưu hóa quá trình vận chuyển; thuật toán tối ưu bầy đàn.

Context. The task of determining a generalized parameter characterizing a comprehensive assessment of the action of criteria affecting the sequence of execution of orders for the manufacture and delivery of products to the customer. Objective. The purpose of the work is to develop an algorithm for calculating priorities when solving the problem of transport services in conditions of uncertainty of choice. Method. When considering the problem of the efficiency of order fulfillment, the reasons are given that affect the efficiency of the tasks being solved for the delivery of paving slabs to the customer in the shortest possible time. In order to select a scheme that reflects the main stages of decision-making, a justification was carried out and a comparative analysis of existing models was carried out. The criteria for the requirements for describing such models have been determined. It is indicated that the objective function depends on a group of reasons, i.e. represents a composite indicator. The stochastic nature of such factors led to the use of statistical analysis methods for their assessment. The limits of variation of the parameters used in the calculations are established. The solution to the multicriteria problem consists in bringing the role of the acting factors to one unconditional indicator, grouping and subsequent ranking of their values. The decision-making and the choice of the indicator will depend on the set threshold and the priority level of the factor. The indices that form the priority of the factor are determined analytically or expertly. The sequence of actions performed is presented in the form of an algorithm, which allows automating the selection of a model and the calculation of indicators. To assess the adequacy of the proposed solutions, tables of comparative results for the selection of the priority of the executed orders are given. Results. The method allows a comprehensive approach to taking into account the heterogeneous factors that determine the order in which the order is selected when making managerial decisions, ensuring the achievement of a useful effect (streamlining the schedule for the delivery of paving slabs to the customer) by ranking the values of priority indices. Conclusions. The proposed scheme for the transition to a complex unconditional indicator (priority index) makes it possible to quantitatively substantiate the procedure for choosing the next order when performing work. A special feature is that the list of operating factors can be changed (reduced or supplemented with new criteria). The values of these parameters will improve and have a higher reliability with the expansion of the experimental design, depending on the retrospective of their receipt, the accuracy of the data. As a prospect of the proposed method, the optimization of the process of selecting applications using queuing methods (for the type of the corresponding flow – homogeneous, without consequences, stationary, gamma flow, etc.) can be considered.
