- ItemEconomic requirements analysis for table grape check weighing(Industrial Engineering, Stellenbosch University, 2011-09) Smit, R.; Treurnicht, N. F.; Blanckenberg, M. M.South Africa’s table grape industry exports most of its production to the developed world where customer satisfaction is very important and strictly regulated. Severe penalties are levied for underweight packaged products and contracts could even be lost. This study aims to determine the feasibility of automated check weighing of final product prior to shipping. The frequency of occurrence of underweight packages is investigated by means of structured interviews conducted within the industry. The probable financial impact of underweight packing is estimated and the paper concludes with a presentation of the capital amount producers can spend to eliminate underweight packaging profitably.
- ItemTable grape punnet packaging : the influence of check-weighing(Southern African Institute of Industrial Engineering, 2012-11) Smit, R.; Treurnicht, N. F.; Blanckenberg, M. M.Most of South Africas table grapes are exported to the EU and the UK. In recent years, pre-packaged table grapes are now preferred in many European supermarkets. This increased demand has resulted in stringent quality standards, including the specification of punnet mass. Locally, table grapes are packed manually using seasonal labour, who often have limited formal education. Punnets must conform to upper and lower mass limits, but many deviations occur due to human and machine error. Check-weighing proved effective in reducing out-of-specification punnets, but human and machine errors were still problem factors.
- ItemUsing Poka-yoke methods to improve employment potential of intellectually disabled workers(Southern African Institute for Industrial Engineering, 2011-05) Treurnicht, N. F.; Blanckenberg, M. M.; Van Niekerk, H. G.ENGLISH ABSTRACT: In this project an electronic manufacturing process, namely ribbon cable assembly, was adapted for execution by intellectually disabled individuals. To make the work accessible to them, human error was controlled by a Poka-yoke approach. The design of the work process used industry standard tooling. Mistake-proofing design identified possible errors, and introduced mechanisms and tests that enabled the worker to avoid them. Test results were analysed using learning theory. It is concluded that intellectually disabled individuals can be enabled to perform the task within normal variation compared with a minimum task time, by using the Poka-yoke approach. Selection, however, is desirable.
