Content available Modelling and numerical analysis of assembly system
EN
The present articles covers a concept of the creation and testing of assembly systems with the use of modern CAD and CAE systems on the example of an assembly system designed for joining parts with circular surfaces that are fitted with positive clearance. The numerical investigations were based on the constructed spatial skeleton pattern of the system. The purpose of the simulation tests was to determine the impact of the measurement and angular inaccuracies of all the elements of the assembly system as well as the inaccuracy of the positioning of the robot’s drives on the positioning accuracy of the parts joined taking into consideration the conditions of assembly in automatic assembly.

Content available remote Production flow synchronisation versus buffer capacities in assembly systems
EN
Purpose: The goal of the considerations carried-out in that paper is the determination of the system synchronisation conditions. Those conditions concern capacities of system buffers. The fulfilment of the developed conditions should guarantee the production flow synchronisation into the expected steady state determined by the system bottleneck. In analysed assembly system rhythmic concurrent production with wide assortment is realised. Design/methodology/approach: The considerations presented in that paper are rooted in the authority method called Requirements and Possibilities Balance Method (RPBM). The experiments in the computer simulations programmes have been carried-out within the confines of the researches. The computer simulation models of the assembly systems using Taylor II for Windows and Enterprise Dynamics have been built. Findings: There are two kinds of system buffers: the entrance buffers and the inter-resources buffers in the assembly systems. The interdependences informing about the required number of elements allocated into the system buffers in order to the production realisation during the first cycle of the system steady state has been formulated. Moreover, the minimal buffer capacities have been determined. Research limitations/implications: The developed interdependences constitute the first step towards formulation of the automatic method designed for the automatic construction of rules controlling the system work during system transition state. That method should enable the automation of the system buffers filling-up. Practical implications: The presented system synchronisation conditions can become an integrated part of existing authority computer system. It aids the decision-making process connected with production planning and control. Originality/value: To develop the interdependences is the main achievement of the given paper. The presented approach permits to solve the problem concerning the production flow synchronisation into the expected steady state determined by the system bottleneck.

Content available remote Required buffer capacities in assembly systems
EN
Purpose: The aim of the realised analysis is the determination of the set of conditions. The fulfilment of those conditions enables the synchronisation of the assembly system work into the steady state. It is necessary to specify the rules controlling the assembly system work. Rhythmic concurrent production with wide assortment in the considered assembly system is realised. Design/methodology/approach: The theoretical roots of the considerations presented in that paper include theory of constraints. The presented approach is consistent with the authority method called Requirements and Possibilities Balance Method (RPBM). Findings: Two kinds of system buffers: the entrance buffers and the inter-resources buffers are considered in that paper. The number of buffers elements needed for production during first steady state of the given system has been determined. Mathematical formulas specifying the minimal capacity of the buffers allocated in the assembly system have been outworked. Research limitations/implications: The formulas specifying the minimal buffer capacity constitute the first step towards formulation of the automatic method. That method is designed for the automatic construction of rules controlling the system work during transient phases between two different steady states. The process enables automation of the introduction filling of the system buffers. Practical implications: The presented formulas can become an integrated part of existing authority software. The developed computer system aids the decision-making process connected with production planning and ensures effective utilisation of production resources. Moreover, the formulas correctness during computer simulations has been verified. Originality/value: To develop the formulas specifying the minimal capacity of the system buffers is the main achievement of the given paper. The presented approach permits to solve the problem concerning the synchronisation of the assembly system work into the steady state.
