Mixed model two-sided assembly lines (MM2SAL) are applied to assemble large product models, which is produced in high-volume. So, the sequence planning of products to reduce cost and increase productivity in this kind of lines is imperative. The presented problem is tackled in two steps. In step 1, a framework is developed to select and prioritize customer orders under the finite capacity of th...

This paper discusses a digital twin-based approach for designing and redesigning flexible assembly systems. The twin allows modeling the parameters of production system at different levels including process, station, line level. dynamically updating in runtime, synthesizing data from multiple 2D–3D sensors order to have up-to-date information about actual process. model integrates both geometri...

Among all the challenges which highlight need of reconfigurability in manufacturing systems, taking into account introduction a new product has been rarely considered by researchers. Indeed, variants future production generation line at initial design stage smooths reconfiguration process line. This paper studies mixed-model assembly planning problem where consists several resources (workers an...

BACKGROUND Changes in industries and work practices have coincided with work-related musculoskeletal disorders (MSDs). This study was conducted to determine the prevalence of MSDs and to assess postural loading in assembly workers of an Iranian telecommunication manufacturing company. METHODS Data were collected from 193 randomly selected workers in 4 units of the company. The Nordic musculos...

This report explores the impact of an innovative compensation system on the development of literacy skills among manufacturing and assembly workers in a high performance organization. The “pay-for-knowledge” (PFK) compensation system ties workers’ wages directly to the work-related skills and knowledge they demonstrate. By developing additional jobrelated skills, workers directly increase their...

Multi-manned assembly line, which is broadly utilized to assemble high volume products such as automobiles and trucks, allows a group of workers different tasks simultaneously in multi-manned workstation. This additional characteristic parallel operators increases the complexity traditional NP-hard line balancing problem. Hence, this paper formulates Type-I problem minimize total number worksta...

Abstract The collaborative robots (cobots) are increasingly being utilized in industries due to the advancement field of robotic technology and also increase labor costs. cobots on assembly line can be complete tasks independently or assist workers tasks. This study considers U-shaped balancing problem with cobots, where several different purchasing costs selected under budget constraint. Three...
