In terms of organisation, the production achieved by polyservice of machines and equipment implies the existence of some independent organisational links. The organisation of the polyservice activity by departments and workshops inside of which great importance should be given to the system of grouping the machines and equipment, studying the optimal conditions to locate them. Organising the production by single or multiple object, continuous or discontinuous flow, manufacturing lines takes into account: the parameters of the flow line, parameters concerning the labour force, the parameters of the machine-tools, technological parameters, etc. Another form of organising the production obtained through polyservice is the production departments in the composition of which there are numerically and automatically controlled machine tools. Organising the production obtained through polyservice may also be done in production departments, in the composition of which there are the transfer machine-tools, processing centres, and manufacturing cells. Organising the flexible manufacturing systems takes into account: the number of benchmarks that will be processed, reduction of the duration to design and make new products, typification and modulation of SDVs, equipping the machines and equipment with standardised SDVs, etc. The most efficient organisational form is the production departments in the composition of which there are the flexible manufacturing cells provided with industrial robots.

Stable Performance

With the recent diversification of demands, manufacturing systems that can respond to multiple types of goods have become more important. In this circumstance, reconfigurable manufacturing systems (RMSs) that can provide flexible manufacturing with limited machine tools through reconfiguration have gained a lot of attention. As an RMS supports flexibility through layout reconfiguration, reconfiguration decision-making is very important and difficult. The development of IoT technology has made it possible to collect hidden information inside systems. This study focused on the reconfiguration decision-making system with the data acquisition system based on IoT technology. The decision-making system detected a reconfiguration situation and built a reconfiguration plan using the data collected by IoT sensors. The performance of the algorithm proposed in this study was verified in a simulation experiment. It was found that the algorithm had a stable performance under various reconfigurable situations. It is expected that the proposed system will help to improve the performance of RMS.

Model And Simulation

Cooperative robots are usually required in flexible manufacturing systems or complex working environments. In particular, when an object under processing is too big or too heavy, a single robot may not be enough to handle it. Two or more manipulators are to be used in such a case. This paper presents the study of the dynamic equations for two industrial robots holding a rigid object. To this end, holonomic constraints are combined with the manipulators and object equations of motion to obtain the dynamic model of the whole system, which can be used for simulation purposes. Experimental results are presented to validate the theoretical results.

Machine Replacement

The main problem of establishing equipment replacement decisions rules under specific conditions is to find decision variables that minimize total incurred costs over a planning horizon. Basically, the rules differ depending on what type of production type is used. For a batch production organization the suitable criterion is built on the principle of economies of scale. Proposed econometric models in this chapter are focused on a multiple machine replacement problem in flexible manufacturing cells with several machines for parts’ processing, and industrial robots for manipulation and transportation of manufactured objects. Firstly, models for a simple case multiple machine replacement problems are presented. Subsequently, the more complicated case is considered where technological improvement is taken into account.
