An object is to reduce the risk of outflow of defects and improve the work efficiency of assembly work. An assembly system 10 according to an embodiment of the present invention is used to assemble a finished product while sequentially placing and fixing multiple types of components to a workpiece. The assembly system 10 includes a collaborative robot 20 configured to collaborate with a worker 100, an identification information reading unit 27 configured to read identification information indicated on a component placed on the workpiece, and a controller 70 configured to determine whether a type of the component placed on the workpiece is correct or incorrect based on the read identification information and control the collaborative robot in accordance with a result of the correctness determination.

This application discloses a computing system implementing a line balancing tool to generate a structured bill of materials for a wire harness based on a harness design and available fabrication processes. The computing system can decompose the structured bill of materials into tasks and assign the tasks to workstations in a production line configured to manufacture the wire harness. The computing system can determine dependencies between a plurality of the tasks and verify the tasks assigned to the workstation conform to the dependencies between the plurality of the tasks. The dependencies can indicate an order for performance of the operations associated with the tasks. The computing system can identify unassigned tasks capable of assignment to one or more of the workstations and determine which of the workstations the unassigned assembly tasks, if assigned, would conform with the dependencies between the plurality of the assembly tasks.

A method and apparatus for monitoring manufacturing of a product. An assembly task network for assembly tasks for assembling is searched by a computer system. The assembly task network defines dependencies between the assembly tasks. A probability of a group of downstream delays as a function of a state of assembly of components for the product being manufactured is calculated using a state of the assembly tasks, enabling modifying incomplete assembly tasks for the product that reduce the group of downstream delays.

A cell control apparatus controls a plurality of manufacturing cells each including a manufacturing machine. The cell control apparatus comprises an operation extraction part configured to extract a transferable operation which can be performed by a manufacturing cell having operation time to spare among operations of a manufacturing cell having delay in operation. The cell control apparatus commands the manufacturing cell having delay in operation to stop at least a part of operations in the transferable operation and commands the manufacturing cell having the operation time to spare to perform the at least the part of the operations.

An information processing device includes: a memory; and a processor coupled to the memory and configured to: assign a task to be executed to each arm of a robot system having arms; determine an execution time period for each operation included in each task assigned to the each arm based on whether the each operation is an operation in an interference region, in which the arms interfere with each other, or an operation in a non-interference region, in which the arms do not interfere with each other; and display workload charts of the arms side by side, an execution time period for each operation and a time period during which no operation is executed being arranged along a time axis in the workload chart of the each arm.
