Abstract: A new formulation to the tolerance allocation based on minimum sensitivity is given. Several synthesis methodologies are reviewed to highlight their importance in details. A brief but complete literature review is given and conclusions are drawn. Objectives such as minimum cost functions, minimum sensitivity functions and minimum variance functions are formulated and a heuristic approach is used for optimisation. An example problem is given to illustrate the concept and results indicate that there are alternatives for tolerance allocation problems. Besides, there are margins of tolerance for which the measure of objective functions are least sensitive.

Keywords: tolerance allocation; minimum sensitivity; heuristics; objective functions.
