The opportunity which opens before manufacturers on the dynamic market, especially before those from the sector of the small and medium-sized enterprises, is associated with the use of the virtual organizations concept. The planning stage of such organizations could be based on supporting decision-making tasks using the tools and formalisms taken f...

... This is due to the geographical dispersion. Additionally, due to shared and concurrent production, the order of tasks and operations is also important [5,6]. All operations must comply with the specifications of the technology documentation. ...
Implementing new solutions in the production hall and offices, companies are looking for solutions that will support the execution of production orders and increase their competitiveness. These changes are caused by new technologies and opportunities by industrial development. These possibilities give a set of solutions that were unknown or impossible to implement in the past. As enterprises develop, they should point on aspect of decision support systems and business process modelling out to. Due to new technologies and IT development, appropriate management of the production processes and business is required. In the article focused on modelling business processes in enterprises. An algorithm for making decisions support in enterprise was also presented.
... The obtained partial cost data is determined by the producers. The information on the output is the next step for the new algorithm [12,13,14,15]. ...
Requirements set by clients regarding, on the one hand, the highest quality of services provided, on the other hand, shorter and shorter order completion dates, cause that enterprises are often unable to cope with them. A production load or limited production resources also means that enterprises are no longer able to accept a new order for their production plan. The following problem is outlined here - send the customer away empty-handed, or try to execute the order, but with a much later execution date and expose to the cost of contractual penalties. Therefore, solutions are sought, which can be particularly advantageous for producers in the small and medium-sized enterprises (SME) sector, for whom this is an increasingly frequent problem - sometimes means "to be or not to be" on the market. One of the possibilities for enterprises is to use the concept of a virtual manufacturing enterprises, which mainly consists in sharing the free production capacity of each producer within the virtual network A network that has been established even between individual enterprises that are geographically dispersed. By establishing a group of several companies cooperating at the same time, one should find such a thread of agreement that it would be possible to cooperate, and also to achieve a common goal, which is to make a final product for the recipient. If it is necessary to make a final product that meets the assumed criteria, it is necessary not only to define the level of cooperation, but also there exists much need for a mechanism to manage and control information flow among manufacturers. Therefore, it is necessary to have information on production issues, such as the quantity and quality of spare production capacities, their access time, additional resources, semi-finished products, and since these are geographically dispersed enterprises, the location of each enterprise is also important. In addition, the network itself is established on the basis of information contained in the production order, so you can adjust the number of participants to your needs, and assign tasks accordingly. All executive actions are taken on the basis of the proposed algorithm, which describes the entire decision-making process, how to collect information, where to keep them, and above all, who should be responsible for providing information.
... In addition to the problem of selecting producers in the network, planning the production flow is a significant problem for this issue. Therefore, it is proposed that generation of possible production routes in a dynamic production network should be determined on the basis of the presented algorithm, taking into account individual spare capacities of all producers [9,10,11]. The planning of production processes 1234567890''"" and the selection of a technological route involves a series of decisions to be taken. ...
The development of production technologies, customer-centric philosophies and, above all, increased uncertainty around today's market, make companies look for solutions that would support their functioning on the market. Keeping up with changes requires, among other things, proper planning of production processes and high investments in innovative technological solutions. For this reason, it is increasingly difficult to make a modern product alone. That is why enterprises from the small and medium enterprises sector are looking for solutions that would enable to continue production without the need to have all the specialized production resources dedicated to individual products. Therefore, companies outsource the choice, configuration and or manufacture components that they are not able to do themselves. Another option is to join the virtual manufacturing network, where manufacturers temporarily share their spare capacity. Such cooperation is possible even for individual enterprises that are geographically dispersed. The proposed solution of generation of possible production routes (based on game theory) also takes into account the time and costs required to transport intermediates between manufacturers (alternative routes). The obtained results are the lead time and costs of manufacturing processes.
... It is very difficult to find the right dynamic parameters of the robot. Better knowledge of the behaviour of the robot improves the simulation [10,16] and gives more accurate results [11,14]. The robot's kinematic system is complex, the robot's geometry is also complex and changes during movement. ...
Nowadays, can be observe an increase in production velocity due to better use of machines. More and more efficient use of machines requires better knowledge of their parameters, especially dynamic parameters. Incomplete knowledge of the parameters increases the safety factor that must be used to make the machine work safely. It reduces the dynamics of the machine, and in consequence of working time is longer. Reducing working time by up to several seconds in one cycle brings measurable benefits in production. It is possible to experimentally shorten the working time, but it requires a lot of tests that need to be done. The machine must be bought for testing. Testing results in machine wear, tool wear and material consumption. It takes a lot of time and work of specialists in difficult conditions. Even a small error during these tests can result in the destruction of the machine and its surroundings. The use of software in which the models are more accurate not only shortens the time of entering the machine into production, but also enables its better use. It is also possible to carry out more experiments before buying a machine and the machine's behaviour is more predictable.
... Programs for offline programming, especially with visualization, avoid many errors at the stage of designing the production line [11,14,16]. These programs allow you to check the reachability of points and collisions of the robot's movement. ...
The life cycle of the product is shortening more and more. Therefore, it is necessary to rebuild the line, the time intended for reconstruction is shorter and the requirements set for the line are greater. This is the reason for changing the way the line is designed. Earlier, the design of the line was based mainly on the designer's experience and intuition. This method was very labour-intensive and required many corrections both at the construction and commissioning stages. This method was very labour-intensive and required many corrections both at the construction and commissioning stages. Sometimes the robot did not reach the points of the trajectory of movement. In this case, it was necessary to move the robot to another place or even replace the robot with another one. This, of course, increases costs and extends construction time. The next stage is programming the robots and other elements of the production line. Even at this stage there are errors that need to be corrected.
As organizações cada vez mais participam de relacionamentos interorganizacionais para maximizar seus resultados e reduzir suas adversidades. Contudo, é comum enfrentar conflitos, demandas por negociações e consequentes tomadas de decisão ao lidar com tais contratos sociais. A proposta desta pesquisa é, através de um mapeamento sistemático da literatura, identificar conflitos, negociações e tomadas de decisões nesses relacionamentos, bem como, melhorias nos processos em andamento. Os resultados do MSL sugerem a falta de uma unificação em termos de processos e ferramentas computacionais adotadas, possibilitando assim novas oportunidades de pesquisa neste contexto.
