The task to research the enterprises when locating them in the new areas is posed and solved. The relevance of the problem is related to both moral and physical aging of production systems, which leads to the need for their modernization and reengineering. For the development of the enterprise, new areas are required to accommodate modern technological equipment. Due to the diversification of the company's activities and the appearance of new orders, it is advisable to place modern production lines with a high degree of automation in new areas. The requirements for the organization of new industries, taking into account the concept of Industry 4.0, have led to the creation of enterprises in the form of virtual industries focused on the creation of new innovative products. The aim of the work is to develop models for the rational location of virtual production in the new areas in conditions of limited enterprise capabilities. Due to the complexity of the problem being solved, the study is carried out in three stages: optimization of location on the earth's surface; creation of the communication infrastructure for virtual production; simulation of the virtual enterprise production cycle. The efficient location of virtual production is carried out using both local and multicriteria optimization. In order to create the communication infrastructure of the virtual enterprise the selection of the optimal route for highway laying is carried out. Simulation of the production cycle is carried out considering time delays and queues when performing technological operations. The new scientific result is the solution of the problem of virtual production system locating on the earth's surface, taking into account the proposed indicators and restrictions, which include the cost of land plots renting (acquiring), as well as the costs associated with earth and construction works. Mathematical methods were used: integer optimization, simulation modeling, agent-based modeling. Keywords: virtual enterprise, optimization of technological objects location, communication infrastructure of the enterprise, simulation modeling, agent-based modeling.

Purpose This paper provides an overview of agent-based modeling and simulation (ABMS) and evaluates the questions that have been raised regarding the “assumptions and mechanisms used” by a well-cited paper that has used this methodology. Design/methodology/approach This work provides a review of agent-based simulation modeling and its capabilities to advance and test theory. The commentary then evaluates and addresses the raised questions and reservations. Findings Agent-based modeling offers unique capabilities that can be used to explore complex phenomena in business and marketing. Some of the raised reservations may be considered as directions for future research. However, the criticisms are for most part unsupported by existing research and do not undermine the contributions of the paper that is being discussed. Practical implications Given its relative novelty, reservations regarding agent-based simulation modeling are quite natural. Discussions like this one would bring together different points of view and lead to a better understanding of how using ABMS can benefit academia and industry. Originality/value This commentary is part of an intellectual dialogue that seeks to provide different points of view about agent-based simulation modeling using a specific paper as an example.

HIV/AIDS spread depends upon complex patterns of interaction among various subsets emerging at population level. This added complexity makes it difficult to study and model AIDS and its dynamics. AIDS is therefore a natural candidate to be modeled using agent-based modeling, a paradigm well-known for modeling Complex Adaptive Systems (CAS). While agent-based models are well-known to effectively model CAS, often times models can tend to be ambiguous and using only using text-based specifications (such as ODD) making models difficult to be replicated. Previous work has shown how formal specification may be used in conjunction with agent-based modeling to develop models of various CAS. However, to the best of the authors’ knowledge, no such model has been developed in conjunction with AIDS. In this paper, we present a Formal Agent-Based Simulation modeling framework (FABS-AIDS) for an AIDS-based CAS. FABS-AIDS employs the use of a formal specification model in conjunction with an agent-based model to reduce ambiguity as well as improve clarity in the model definition. The proposed model demonstrates the effectiveness of using formal specification in conjunction with agent-based simulation for developing models of CAS in general and, social network-based agent-based models, in particular.

Agent-based (simulation) modeling is one of the methods of studying complex systems, processes, and phenomena in various spheres of human activity: business, service, manufacturing, science, medicine, transport services, and logistics. In this study, a model is built – an approximation to a real object (system, process), especially in relation to the most important economic properties for the study. By experimenting with the model, you can extract indicators that are of interest for the functioning of the real enterprise system. Having obtained sufficiently stable statistics from these data, you can use it in the future for economic planning or forecasting, which is an essential tool for sustainable development in general.

It is stated and solved the complex task related to the arrangement and management of the virtual enterprise (VE) in the aerospace industry where high-tech innovative products produced. The complex task divided into several stages. At the first stage, the task of building a portfolio of VE orders solved. In order to do this, the state of the high-tech products market is analyzed to identify the competitive products. The alternatives of the order portfolio compared and evaluated considering the costs, timing, and risks of output. The composition of the VE enterprises selected at the second stage of the built portfolio of orders. For this purpose, the enterprises selected according to the principle of subject orientation considering the possible costs associated with the adaptation of the selected enterprises to fulfill the order portfolio. The info-communication links to manage the VE formed at the third stage. The cost and capacity of the communication equipment for transmission of control and technological information within the framework of the VE taken into consideration. The production cycle of the VE formed at the fourth stage considering the logistics requirements. The characteristics of the logistics chain "supply-production-sale" for each enterprise in the composition of the VE taken into consideration. At the fifth stage, the quality management system of the VE production considered. In order to ensure the quality, the corresponding activities that affect not only the quality of the product in the logistics chain but also the whole production processes (both basic and auxiliary) are carried out. At the sixth stage, the logistics processes of VE supplying and marketing optimized. The optimization of supply and marketing processes provides a reduction of product cost as well as the increased competitiveness in the market of high-tech products. The proposed tasks are logically related to each other and aimed at ensuring the competitiveness of domestic machine-building enterprises (aircraft construction, shipbuilding, etc.). In order to solve the proposed complex problem the methods of system analysis, integer optimization, simulation, agent and knowledge-oriented modeling are used. The proposed approach allows to justify the order portfolio, make the organizational structure of the enterprise, build the info-communication interaction between the executors, justify the quality requirements and also to organize the logistics chain of supply, supply, production and marketing of high-tech products, taking into account the terms of fulfilling the order portfolio and optimizing costs that is very important for domestic aircraft building
