Direct costs quality control

One approach for using DOE on more complex processes is to do the majority of the process development on smaller, representative sections of material, such as test panels, rather than on full-scale parts, and then to scale up with a more limited experimental matrix. There is no guarantee that experience on small-scale test panels will directly translate to large parts because dimensions and thickness of the part are important variables in their own right. Another way to save on costs is to start with a satisfactory process and to continue, via careful monitoring of process variations and results, to extend the range of experience. This method is variously called statistical process control or statistical quality control. 

The production of material of a consistent quality is one of the major goals of development work. Quality problems in a product are identified by the constant monitoring and analysis of the output from the plant, using statistical process control techniques [D-4]. Some of these methods have already been mentioned in Section B, 3.4.2. The avoidance of product quality problems results in direct cost benefits and also brings about a reduction in the environmental impact of its manufacture. This is because material does not need to be reworked, recycled or sent for disposal. A reduction in the number of inferior quality batches of material leads to an increase in output from the plant. More material is produced for the same effort, with the added benefit that it can be consistently supplied to the sales warehouse or be used in consuming processes. 

In the lab, future expansion plans include the use of optical scanners for reading sample labels, operation of robots to relieve some of the manual operations and an artificial intelligence system to track quality control. In other areas, there will be an increase in the number of real time monitors, not necessarily because real time data is needed, but the cost can be small compared to sending out a field team. There will be some applications of direct monitoring by satellites such as LANDSAT D. Both of these will be incorporated into water quality models which will allow more intelligent choices of where to send a field team to collect samples for detailed analysis.

In addition to the limited range of cellulose-compatible synthesis protocols, two further drawbacks remain that are inherent to on-array approaches. Because synthesis takes place directly on the surface that is subsequently used for screening, quality control of the synthesis products is restricted to the surface-bound molecules. Standard cleave-and-characterize procedures involving LC-MS analytical techniques are not practical. This is a severe problem even for the synthesis of peptides where well-established protocols are available and becomes more pronounced when novel chemistries have to be employed. Secondly, each array produced is unique, which renders the production rather costly and prevents the generation of numerous copies of the same array for high-throughput applications. 

Construction Material and Labour Costs. In the Australian context, reduction of site labour costs for fabrication or construction is important, owing to the relatively high influence on project execution costs that labour exhibits when compared to materials. This applies not only for direct labour, but also to indirect labour required for adequate supervision, quality control and safety management at the workplace. Hence it is common for infrastructure to be fabricated as Pre-Assembled Modules (PAM) in a location where such labour is more cost-efficient. The need for pre-assembly of structures also tends to drive designers towards size and weight-efficient steel assemblies, rather than concrete or other materials, in order to reduce freight costs.
