Kit preparation for mixed-model assembly: efficiency impact of confirmation methods
Journal article, 2019
Design/methodology/approach – An industrially relevant laboratory experiment is applied, simulating kit preparation with order batching for mixed-model assembly. The time efficiency is studied as associated with four confirmation methods – barcode ring scanner, button presses, voice commands and RFID-reading wristbands – when applied as pick-from and place-to confirmation. Furthermore, the paper also considers the quality outcome.
Findings – Efficiency is promoted by methods that minimise interrupting the picker’s motions when performing pick-from confirmations and with methods that allow each hand to place components and perform place-to confirmations simultaneously – here represented by button presses and RFID-reading wristbands. Moreover, combining various methods for the tasks of pick-from or place-to confirmation can benefit efficiency.
Research limitations/implications – Pickers at an early stage of the learning curve (one shift of training) were considered.
Practical implications – The findings promote the customised applications of picking information systems in industry.
Social implications – Combining various methods for the tasks of pick-from and place-to confirmation can provide more fitting applications that better align with the picker’s preferences.
Originality/value – Combinations of various methods when applied as either pick-from or place-to confirmation, or both, are studied.
