LCA methodology description

Introduction My previous post identified how a process specification perspective can be applied to provide some structure and semantics for methodology description and execution, taking the Life Cycle Assessment (LCA) methodology as example. In this article, we'll apply this perspective and expose a well-rounded ontology that captures the full Life Cycle Assessment (LCA) methodology description. To keep the core structure of the ontology within context, we'll reuse the four basic notions provided by the Process Specification Language (PSL) ontology (ISO18629-1:2004). These ... Read more

A process specification perspective on LCA

Introduction Life Cycle Assessment (LCA) is a methodology for studying a product system, from a sustainable engineering viewpoint, and quantifying and evaluating the environmental burden of that product system during its entire lifecycle. By objectively understanding the environmental profile of a product system, it becomes possible to propose and evaluate alternative product systems with potentially lesser environmental impact, where the results of the study are used to drive decision making. LCA considerations are highly important and should be factored into any ... Read more

Knowledge model for assembly planning

Design for assembly, disassembly, service and recycling are important approaches used in the area of product design engineering to plan for the efficient design, manufacture, operation and disposal of multi-part products from an assembly/disassembly viewpoint. The application of these approaches help optimize designs, simplify assembly methods during production, whilst reducing costs and lead times in several ways, amongst others. When making decisions about through-life product planning, adequate consideration needs to be given to design for assembly, disassembly, service and recycling. However, ... Read more

A starter ontology for Value Stream Mapping

Value stream mapping is a lean management technique typically used in manufacturing business process re-engineering, but is equally suited for other kinds of business process improvement initiatives. The approach is deployed for assessing the current states of processes and practices and proposing improved future states. The following steps are generally tackled in order to successfully complete the approach: A suitable product family candidate is identified by analysing product quantities and routings. The takt time is calculated and a current ... Read more
