“…While the order of the work packages is calculated online by the assistance system depending on the product variant, the available resources and the current progress status [1], the order of the work processes within the work package is preplanned and therefore fixed. However, the work steps within a work process do not have a predefined order but a priority.…”

“…Due to these properties and the resulting complexity of the production system the resource allocation and progress control are traditionally performed manually by foremen and supervisors. New software solutions that dynamically calculate a proper resource allocation are able to disburden the supervisors in such production systems [1]. They provide a situation related allocation of personnel resources.…”

The digital progress monitoring of manual assembly processes at goods with huge dimensions is a challenging task. The paper presents an approach using 3D-image sensors for gesture control and progress recognition. The developed system is able to avoid time and effort consuming walks of workers between assembly objects and computer terminals. Progress recognition of assembly processes is realized by interpreting the movements of the workers’ hands and by detecting the passing of defined coordinates within the assembly and warehouse areas.

“…SALBP (simple assembly line balancing problem) is important for the assembly line of a single product, where only the limitations resulting from the priority between tasks are considered. In the literature (Kriengkorakot and Pianthong, 2007;Tracht et al, 2015) four types of SALBP are distinguished: -Type 1 (SALBP-1) -minimize the number of stations while maintaining the cycle time -Type 2 (SALBP-2) -minimize cycle time (i.e. increase production rate) in the absence of variability in the number of assembly stations.…”

In the paper the possibilities of process re-organizing in relation to simple principles for limiting waste in the production cycle have been presented. Based on value stream mapping and monitoring of performance indicators, the possibilities of changes identification of in the assembly line process have been presented. Furthermore, based on the availability, performance and quality values, it has been proved that relatively small changes can have a very positive effect on the assembly process. Based on the OEE coefficient, it has been found that the proposed changes improved the process's efficiency by more than 20%.

Abstract:Manual assembly performed at assembly workstations nowadays still has a unique place in different kinds of production. To increase the productivity and quality of manual assembly it is necessary to analyse the existing workplaces and find ways to improve and streamline work done at these workplaces. The article deals with the design of a model for on-line analysis of a manual assembly process. The proposed model is based on the use of sensors or the so-called button-box and the use of software for recording and evaluating data. Based on the obtained data it is then possible to evaluate the time characteristics of the assembly process, as well as to find sources of delays and mistakes and then take appropriate action to correct them.
