Evaluation for the implementation of single-use technology (SUT) can be accomplished by utilizing a structured analysis by linking a single-use design (SUD) template with a failure mode and effects analysis (FMEA) template. The SUD template, coupled with FMEA, has been developed as a tool to document process steps and parameters. This enables the correlation of process steps and parameters with a risk assessment for the use of single-use systems (SUS) and SUT. The many facets of SUT implementation will be reviewed, and the use of the structured tool will be applied. Fixed stainless steel systems have the benefit of a fully scrutinized Installation Qualification/Operational Qualification (IQ/OQ) prior to use in manufacturing. SUT performing operations would benefit from having an abbreviated IQ/OQ applied every time a SUS/SUT is used. Process documentation via the SUD template is coupled with a risk-based evaluation of design approach via an FMEA template that could help to document process risks. This numerical evaluation also allows for sensitivity analysis to be performed so that key risk assumptions can be evaluated in a proactive way to support decision making.

A non-conventional method of crane runway upgrade solutions converts the girder into a truss-type structure. This paper explores the mechanics behind this proposed method and its advantages over conventional methods of girder reinforcement.

The paper has discussed the many aspects of an operation that an Industrial Engineer may be involved with and some of the tools the engineer may use. Projects can be as simple as evaluation of the efficiency of using a crane vs. a fork truck for material handling. Projects can be as complex as a melt shop operation feeding a continuous slab caster, feeding a hot strip operation, or the melt shop feeding a mold facility, feeding a forge operation. As you can see, the Industrial Engineer is very versatile and in a sense is an additional evaluation tool which can aide in process design, process evaluation, and continuous improvement.

A typical request from steel mill management in the process of increasing the mill's production is, "Tell us how much of an increase of the crane-lifted load capacity can handle our existing building structures." The response to this request should be, "What are your requirements for increasing the crane-lifted loads, and how much can you afford or want to spend?" It is a difficult and time-consuming process to investigate the existing crane runway and building structures in search of the weakest link (crane girders, columns, roof trusses or all three), without knowing the desired new (upgraded) crane lifting capacity that would satisfy the mill production needs. A qualified engineer can use all available engineering tools, including crane load dynamic analyses, field tests and space frame response of building framing to crane loads, to optimize the results, but engineers need to know what the ultimate goal is.
