Manufacturers' product liability in Australia

The thesis, by examining statute and common law, demonstrates that Australian law is deficient in its endeavour to impose liability on manufacturers for defective products, and also with respect to the provision of compensation to consumers/users who suffer loss or injurty therefrom.

Pervasive limitations : innovating with ambient intelligence (AmI) technologies and restricted absorptive capacity in Australian SME manufacturers

The last 25 years have seen rapid increases in the number and sophistication of technological and process innovations in large manufacturers, producing dramatic improvements in productivity and efficiency. However, smaller manufacturers’ adoption of such innovations has been uneven. Ambient Intelligence (AmI) technologies are being positioned as the next performance and productivity enhancing purchase for manufacturers. This paper defines and gives examples of AmI technologies in current use, summarises AmI technologies of potential interest to small and medium enterprise (SME) manufacturers, and identifies potential impacts of restricted absorptive capacity in SMEs on the adoption of AmI technologies. Comparing two SME manufacturers, one from Germany and one from Australia illustrates a potential application of generic AmI technology based business solutions to a range of SME manufacturers.

Strategy and continuous improvement in small-to-medium Australian manufacturers

While Australian firms have generally recognised the value of continuous improvement (CI) in improving performance, many have yet to develop systems to ensure that the efforts of the CI program are focussed on issues of strategic importance to the company. In fact, as recognised in operations management generally, CI activities can have a significant impact on the development of strategy as well as its implementation. The research reported here uses a CI mapping methodology to chart the relationship between CI and strategy in small- to medium-sized manufacturers. Analysis of the link between the firms’ strategies and CI programs indicates that most firms involved in the study made little attempt to link the two and some appear to be unaware of any need to do so. However, such findings seem to be dependent on company size, the maturity of the CI program and the competitive position of the firm. The paper also includes an examination of the role of operations and shopfloor CI in company strategy, particularly as related to SMEs.

Inadvertent doping through supplement use by athletes: assessment and management of the risk in Australia

Many athletes report using a wide range of special sports foods and supplements. In the present study of 77 elite Australian swimmers, 99% of those surveyed reported the use of these special preparations, with 94% of swimmers reporting the use of non-food supplements. The most popular dietary supplements were vitamin or mineral supplements (used by 94% of the group), herbal preparations (61%), and creatine (31%). Eighty-seven percent of swimmers reported using a sports drink or other energy-providing sports food. In total, 207 different products were reported in this survey. Sports supplements, particularly supplements presented as pills or other non-food form, are poorly regulated in most countries, with little assurance of quality control. The risk of an inadvertent "positive doping test" through the use of sports supplements or sports foods is a small but real problem facing athletes who compete in events governed by anti-doping rules. The elite swimmers in this survey reported that information about the "doping safety" of supplements was important and should be funded by supplement manufacturers. Although it is challenging to provide such information, we suggest a model to provide an accredited testing program suitable for the Australian situation, with targeted athlete education about the "sports safety" of sports supplements and foods.

Tip top result goes stale: ACCC-v- Australian Safeway Stores Pty Ltd(No 2)

Bread, its constituents, its methods of manufacture and its price and availability to consumers can claim to be the leitmotiv of competition law, both ancient and modern. The inelasticity of demand for such a staple food explains laws against monopolies being included in the eighteenth century BC Code of Hammurabi, why corn laws exercised the minds of the Gracchi brothers in second century B.C. Rome, and why ineffective regulation of the price of bread was seen as an important precipitator of revolutions in Europe in the eighteenth and nineteenth centuries. In the common law the early restraint of trade case, Mitchell v Reynolds saw a parish wide five year non-competition clause in a contract for the sale of a bakery upheld as reasonable. In the post-Shennan Anti-Trust Act (1890) United States, attempts by manufacturers of macaroni to change its constituents because of the prevailing high price of durm wheat were held in National Macaroni Manufacturers Association v FCT) to constitute price-fixing, an offence illegal per se under American anti-trust law.

Strategy not tactics drives aggregate planning

The aggregate planning model supposedly shows how manufacturers cope with seasonally biased sales. Unfortunately, industry has failed to embrace any of the sophisticated algorithms that were developed to solve the corresponding resources allocation problem. This paper reveals why such methods have proven so unattractive. Aggregate planning is a chimera. In practice, planners construct the master production schedule directly, in line with a preferred production strategy. A “chase” plan is the most popular choice. When this option proves infeasible, management plumps for another predetermined strategy. The resultant stockpiling brings certain financial risks. However, companies take various measures to reduce their exposure.

Snowballing obesity: Australians will get run over if they just sit there.

* Overweight and obesity are very common in Australian adults (56%) and children (27%). * Rates of overweight and obesity are snowballing and will place greater burdens on health services for the treatment and care of chronic diseases. * Prevention is urgently required from health, social and economic perspectives, but the response to date has been inadequate.
* A long-term, sustained action plan starting with a focus on young people is needed. This should particularly address the “obesogenic” environments causing the epidemic. * Although whole-of-government action is required, support from and involvement by parents, carers, community leaders, healthcare professionals, teachers, childcare workers, urban planners, recreation managers, food manufacturers, employers, advertisers, and communicators is essential. *  The health sector should take the lead, but success will only come from concerted and integrated action across the whole of society. * There are now signs of political commitment to addressing overweight and obesity. Doctors should get behind this and help mobilise community support.

Aggregate planning for seasonal demand : reconciling theory with practice

Purpose: The paper reports on the ramifications for production planning when monthly sales exhibit predictable seasonal highs and lows. The literature first acknowledged and dealt with the (aggregate planning) problem 50 years ago. Nevertheless, there is neither evidence that industry has adopted any of the mathematical techniques that were subsequently developed, nor a convincing explanation as to why not. Hence this research sets out to discover the methods manufacturers use to cope with seasonal demand, and how germane the published algorithms really are.

Design/methodology/approach: Forty-two case studies were compiled by interviewing senior managers and then conducting plant tours. No prior assumptions were made and the list of questions covered the gamut of production planning.

Findings: The main finding is that manufacturers select a straightforward production strategy, right from the outset, so the fundamental cost-balancing format is not relevant. The majority pick a “chase” strategy, since most organizations subscribe to a “just in time” ethos. Whenever a different strategy is preferred the rationale springs from skilled labour considerations or binding facilities constraints. The chosen strategy serves as a road map for resources acquisitions, and the master production schedule is constructed directly. So, the complex issue of how to disaggregate an optimal aggregate plan never even arises. Managers do not seek perfect solutions, but strive to eliminate, or contain, the most significant marginal costs. The nature of the business determines the most appropriate tactics to employ.

Originality/value: These findings break the mould as far as orthodox aggregate planning is concerned and show why theory is at odds with practice, whilst reaffirming the importance of concepts such as “flexibility”, “integration”, and “just-in-time production”.

Measuring the influence of fibre-to-fabric properties on the pilling of wool fabrics

This study ranks the contribution of various fibre, yarn and fabric attributes to the pilling of wool knitwear. On the basis of an artificial neural network modelling, a combination of sensitivity analysis, forwards/backwards search and genetic algorithms was used to identify the importance of various fibre/yarn/fabric input parameters. The three different techniques show broad similarities in their assessment of which input parameters are important or are not important in affecting fabric pilling. The ranking shows that fabric cover factor has the most effect on pilling, followed by yarn count and thin places, fibre length, yarn twist, etc. It is further illustrated that the directional trend of the predicted pilling outputs for a selection of inputs was in line with the expected behaviour. To verify the findings of input feature selection, input factors deemed to have a small effect on the predicted pilling output, such as fibre length and diameter variations and curvature, were removed and the subsequent performance statistically compared to the original multi-layer perceptron. Differences between the outputs predicted by the original and pruned models are found not to be statistically significant at the 5% significance level. Results from this study may help manufacturers and knitwear designers in choosing the most appropriate materials and structures to reduce the pilling propensity of wool knitwear.

Fault detection in a cold forging process through feature extraction with a neural network

This paper investigates the application of neural networks to the recognition of lubrication defects typical to an industrial cold forging process employed by fastener manufacturers. The accurate recognition of lubrication errors, such as coating not being applied properly or damaged during material handling, is very important to the quality of the final product in fastener manufacture. Lubrication errors lead to increased forging loads and premature tool failure, as well as to increased defect sorting and the re-processing of the coated rod. The lubrication coating provides a barrier between the work material and the die during the drawing operation; moreover it needs be sufficiently robust to remain on the wire during the transfer to the cold forging operation. In the cold forging operation the wire undergoes multi-stage deformation without the application of any additional lubrication. Four types of lubrication errors, typical to production of fasteners, were introduced to a set of sample rods, which were subsequently drawn under laboratory conditions. The drawing force was measured, from which a limited set of features was extracted. The neural network based model learned from these features is able to recognize all types of lubrication errors to a high accuracy. The overall accuracy of the neural network model is around 98% with almost uniform distribution of errors between all four errors and the normal condition.

The effect of cure cycle heating rate on the fibre/matrix interface

Development of civil aerospace composites is key to future “greener” aircraft. Aircraft manufacturers must improve efficiency of their product and manufacturing processes to remain viable. The aerospace industry is undergoing a materials revolution in the design and manufacture of composite airframes. The Airbus A350 and Boeing 787 (both due to enter service in the latter part of this decade) will push utilisation levels of  composite materials beyond 50% of the total airframe by weight. This  change requires massive investment in materials technology, manufacturing capability and skills development. The Quickstep process provides the ability to rapidly cure aerospace standard composite materials whilst providing enhanced mechanical properties. Utilising fluid to transfer heat to the   composite component during the curing process allows far higher heat rates than with conventional cure techniques. The rapid heat-up rates reduce the viscosity of the resin system greatly to provide a longer processing window introducing greater flexibility and removing the need for high pressure during cure. Interlaminar fracture toughness (Mode I) and Interfacial Shear Strength of aerospace standard materials cured using Quickstep have been    compared to autoclave cured laminates. Results suggest an improvement in fibre-matrix adhesion.

Advanced manufacturing technology adoption - the German experience

The decision process that organisations utilise when evaluating technology investment opportunities is a complex and even political process; however, the correct decision can provide the organisation with considerable operational and competitive benefits. The research presented in this paper presents the findings of a postal survey of the benefits provided by technology investments to large German manufacturers. It was found that only where middle management generated the idea for the advanced manufacturing technology (AMT) investment was success in that investment significantly more likely. Respondents who established a project team to plan the technology proposal, regardless of the department which generated the ideas for technology investment, were not significantly associated with a greater likelihood for success.

The respondents typically took between 3 and 12 months before making the final decision to invest, irrespective of the department generating the idea for the AMT, and a further 6 months to implement the AMT. Respondents who utilised a discounted cashflow analysis took significantly longer to make the final decision to invest. The greatest number of manufacturing outcomes of significantly higher importance was identified for respondents where Engineering, IT or R&D generated the AMT ideas. It was also determined that the respondents most frequently considered AMT investments in computer hardware or software and technical training for process workers to be necessary at the time of considering the investment. Middle management were found to be significantly more concerned than managers on other levels about opposition of workers to the AMT, while the process workers were significantly more concerned about interruptions to the process during installation.

Tendering for low cost generics in Australia

An Australian federal government committee recently proposed, as a cost-saving measure, the introduction of sealed-bid competitive tendering to exclusively supply the Pharmaceutical Benefits Scheme with specific generic medicines. A similar plan involved an open tender to supply generic products below a government set price, also linked with a reduced patient co-payment as an incentive. These proposals represented an opportunity to encourage the price of generic pharmaceuticals to move closer to the marginal cost of production—a process that could be subsequently applied to innovative (or brand-name) patented medicines in a therapeutic class with many competitors. This article examines these tendering proposals, particularly in relation to the potential for increased involvement of generic pharmaceutical manufacturers in the Australian market.

Impact of the Pick and Tick food information program on the salt content of food in New Zealand

The Pick the Tick programme of the National Heart Foundation of New Zealand aims to provide a framework for cooperation with the food industry to improve nutrition labelling and to develop a healthy food supply. Food manufacturers, whose products meet defined nutritional criteria, are able to display the Pick the Tick logo on food labels. The tick is used by 59% of shoppers in assisting them make healthy food choices. Food companies are encouraged to reformulate product composition if they fail to meet criteria and develop new products to specifically meet the Pick the Tick criteria. The objective of this study was to evaluate the impact of the programme on food formulation. The main outcome measure was the amount of salt not added to food products. Changes to sodium levels were multiplied by the volume of sales and then converted to salt in tonnes to provide a tangible measure of the impact of the programme. In a 1-year period, July 1998 to June 1999, Pick the Tick influenced food companies to exclude ~33 tonnes of salt through the reformulation and formulation of 23 breads, breakfast cereals and margarine. Breakfast cereals showed the largest reduction in sodium content by an average of 378 mg sodium per 100 g product (61%). Bread was reduced by an average of 123 mg per 100 g product (26%) and margarine by 53 mg per 100 g (11%). Pick the Tick appeals to the food industry as a tool for marketing food products and has provided an incentive to improve the nutritional value of foods. The tick on approved products not only acts as a ‘nutrition signpost’ for consumers but can also significantly influence the formulation of products without sacrificing taste or quality.
