Comparison of Labour Standards for a Greenhouse Tomato Production System A Case Study

Comparison of Labour Standards for a Greenhouse Tomato Production System A Case Study The development of labour standards for the single truss tomatoproduction system is examined. Both time study and predetermined timesystems, such as the Element Times for Agriculture ETA tables and theMaynard Operation Sequence Technique MOST tables, are used todetermine labour standards for the operations of pruning and harvestingin a single truss tomato production system. The hypothesis is that apredetermined time system could be used to establish greenhouse labourstandards, and thus replace the tedious and costly process of directtime study. Such a work measurement system would enable the setting ofjob standards quickly and accurately. Standardised work models willfacilitate cost control of labour operations, and provide data forevaluation of labour costs within future greenhouse system designs. Thedata indicate that, although the predetermined time values varied frommeasured time study by around 6 per cent to over 23 per cent forpruning, the variation for harvesting ranged approximately from 3 percent to 7 per cent. The combined results suggest that predetermined timesystems can be used effectively to establish greenhouse labour standardsfor short cycle tasks without the loss of significant accuracy whenusing an absolute scale. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png International Journal of Operations & Production Management Emerald Publishing

Abstract

The development of labour standards for the single truss tomatoproduction system is examined. Both time study and predetermined timesystems, such as the Element Times for Agriculture ETA tables and theMaynard Operation Sequence Technique MOST tables, are used todetermine labour standards for the operations of pruning and harvestingin a single truss tomato production system. The hypothesis is that apredetermined time system could be used to establish greenhouse labourstandards, and thus replace the tedious and costly process of directtime study. Such a work measurement system would enable the setting ofjob standards quickly and accurately. Standardised work models willfacilitate cost control of labour operations, and provide data forevaluation of labour costs within future greenhouse system designs. Thedata indicate that, although the predetermined time values varied frommeasured time study by around 6 per cent to over 23 per cent forpruning, the variation for harvesting ranged approximately from 3 percent to 7 per cent. The combined results suggest that predetermined timesystems can be used effectively to establish greenhouse labour standardsfor short cycle tasks without the loss of significant accuracy whenusing an absolute scale.
