It is widely acknowledged that the allocation of part tolerances is a highly responsible task
due to the complex repercussions on both product quality and cost. As a consequence …

The paper deals with the cost-tolerance functions used in minimum-cost tolerance allocation
on mechanical assemblies. The consistency of the cost-tolerance functions associated with …

Due to inevitable design iterations, requirements are frequently changed and revised. If not
effectively managed, undesired propagating changes may result in monetary and time …

Many tolerancing problems on mechanical assemblies involve a functional requirement
depending on a chain of parallel dimensions on individual parts. In these one-dimensional …

The uncertainties of parameters are inevitable in practical engineering problems, which may
cause unexpected variations of objectives and constraints. Tolerance design methods can …

The recent notable emergence of a body of research in requirements management on one
hand and benefits realisation has contributed to addressing a growing need for improved …

When allocating tolerances to geometric features of machine parts, a target variation must
be specified for some functional requirements on the assembly. Such decision, however, is …

Design engineers play a vital role in conceptualizing and designing an assembly. The
assembly is then disintegrated into several subassemblies and geometric tolerance symbols …

The key purpose of robust design and tolerancing approaches is the management of
uncertainty. Against this background, it is not surprising that there is a large overlap between …

The surface machining precision of parts is closely related to the contact performance
between the mating surfaces of the assembly, and it will create a waste of resources to …
