Fault-Tolerant Facility Allocation
2013The problem of Fault-Tolerant Facility Allocation (FTFA) is a relaxation of the classical Fault-Tolerant Facility Location (FTFL) problem (Jain K, Vazirani VV (2000) An approximation algorithm for the fault tolerant metric facility location problem.

Allocation of risk tolerance criteria
Process Safety Progress, 2013Risk analysis evaluates the risk of individual hazard scenarios and hazardous events that contribute to the overall risk of a hazardous facility. Therefore, some practitioners employ risk tolerance criteria for hazard scenarios or hazardous events by allocating or apportioning overall facility risk to the scenarios or events.

An implicit enumeration approach to tolerance allocation in sequential tolerance control
IIE Transactions, 1999The accuracy and precision of a manufactured dimension is largely dependent on the accuracy and precision of the technological processes selected for its execution. It is not unusual to have available several competing technological processes for execution of each manufacturing operation specified in a process plan, where it is generally assumed that ...

Optimal Tolerance Allocation for Improved Productivity
IFAC Proceedings Volumes, 1992Abstract Industrial quality is presented as a direct result of manufacturing practices (e.g., tolerance allocation, process selection, inspection procedures). A quality indicator is developed that allows for the computation of a function representing the cost of an industrial product versus its quality level.

Allocation of assembly tolerances to minimize costs
CIRP Annals, 2019Abstract The cost and quality of an assembly depend on the processes used to manufacture its components. The specific processes and process settings are often dictated by the tolerances on the components. One long-standing challenge is allocating the assembly tolerance to components. Many methods have been proposed, most of which endeavor to minimize

Tolerance Allocation Using Design of Experiments
Applied Mechanics and Materials, 2015Tolerance design plays a very important in any manufacturing process because this activity directly influences products cost and quality. In design activity the designer solve the quality problems selecting tight tolerances for components but this generates cost increasing.

Tolerance allocation by means of the polyhedral based tolerance analysis method
CIRP Journal of Manufacturing Science and TechnologyThe imperfection in the geometry and size of mechanical parts can lead to problems of assemblability and/or overall functionality. Defining acceptable tolerances for these imperfections is challenging because they impact how well the machine works and how much it costs to manufacture.

Tolerance allocation using neural networks
The International Journal of Advanced Manufacturing Technology, 1995The purpose of tolerance allocation is to find a combination of tolerances to individual components such that the assembly tolerance constraint is met with minimum production cost. There are several methods available to allocate or apportion the assembly tolerance to individual parts.

Optimal Tolerance Allocation With Loss Functions
Journal of Manufacturing Science and Engineering, 1999The tolerance allocation problem is formulated as a nonlinear integer model under the constraints of process capability. The problem is to minimize the sum of machining cost and quality loss. When the statistical tolerance limits are used and Taguchi’s quadratic loss function is defined, the total cost function becomes a convex function for a given ...
