Operations management issues in design and control of hybrid human-robot collaborative manufacturing systems: a survey

“…The introduced approach includes an inventory of common manual and automated tasks, resources needed to execute these tasks, design of products to be produced, and analysis of different tasks allocation to humans and cobots based on their capability. Some researchers have only recently begun to study HRC systems in the context of operations management (Darvish et al, 2018;Bogner et al, 2018;Michalos et al, 2018b). The related topics include system's design (Chen et al, 2011;Michalos et al, 2018b), line balancing (Weckenborg et al, 2019), scheduling (Bogner et al, 2018;Casalino et al, 2019), resource allocation (Takata & Hirano, 2011), and task planning and assignment (Chen et al, 2013;Hu & Chen, 2017;Darvish et al, 2018).…”

“…There exist methods for the design of HRC systems in cellular manufacturing systems (Tan et al, 2009(Tan et al, , 2010, flexible assembly lines , 2018, and cellular manufacturing systems (Kato et al, 2010;Hu et al, 2013). The typical methods to tackle operations management problems in HRC systems include linear/non-linear programing (Hu & Chen, 2017;Bogner et al, 2018), (mixed-)integer programing (Weckenborg et al, 2019), heuristics (Bogner et al, 2018) metaheuristics algorithms (Chen et al, 2013;Weckenborg et al, 2019), multi-criteria evaluation approach (Michalos et al, 2018b), and simulation models (Darvish et al, 2018;Bänziger et al, 2018).…”

“…The HRC production environment creates specific constraints for an operations management problem. For instance, the presence of both humans and cobots in the line affects the sequencing of tasks and products (Bogner et al, 2018), and the tasks assignment must account for processing times, skills, physical and mental conditions, geometrical dimensions. HRC systems often require online task assignments to humans and cobots based on their current states (Darvish et al, 2018) and characteristics (Chen et al, 2013).…”

A New Shopfloor Orchestration Approach for Collaborative Human-Robot Device Disassembly

“…Zhang and Shah [5] develop multi-abstraction search for addressing the multi-agent placement and task orchestration problem, where agent placement, task assignment and task scheduling happen sequentially and form the starting point for a satisficing scheduler. Bogner et al [4] present a Mixed-Integer Linear Programming (MILP) formulation for single-and multi-task HRC with application in PCB production, a set of efficient heuristics and a metaheuristic approach.…”

“…Coordination of small human-robot teams undertaking collaborative tasks is a well-studied topic in the literature 1 Authors are with the Centre for Research and Technology Hellas / Information Technologies Institute (CERTH / ITI) (ihatz,dgiakoum,Dimitrios.Tzovaras)@iti.gr [1], [2], [3], [4]. In this type of problem, small teams of humans and robots collaborate on a single task, and the goal is to assign and sequence operations so as to achieve a problem-dependent objective, such as minimizing makespan or cost.…”
