Methods and apparatus for work management and routing

Methods and apparatus for service-level based and / or skills-based assignment of a work item to one (or more) of a plurality of resources based on fitness, for example, of skills required by the former to those provided by the latter. Assignment takes into account the level of stress on the work item and / or resources, such that the number of resources fit for assignment varies as the level of stress varies. Systems according to the invention can be used, by way of example, to route a call or other request made by a customer to a service center. The requirements for processing the call (determined, for example, by an incoming call operator) are matched against the skill sets of available customer service agents, taking call and / or resource stress levels into account. For example, some implementations may match an incoming call having a low stress factor (e.g., a newly received call from a standard customer) to a smaller pool of agents with both required and desired skills, while assigning a call with a higher stress factor to a larger pool of agents with at least required skills. Other embodiments may match an incoming call having a low stress factor to the larger pool of agents having at least the required skills, while assigning a call with a higher stress factor (e.g., a call from a priority customer) to an agent from the smaller pool of agents who have both required and desired skills.

Micro material mechanical performance testing platform under stretching-bending-twisting multi-loads

The invention relates to a micro material mechanical performance testing platform under stretching-bending-twisting multi-loads, and belongs to the field of electromechanics. The micro material mechanical performance testing platform comprises a tension and compression module, a bending module, a twisting module, a detection control module and a test-piece clamping module, wherein the testing platform takes the tension and compression module as a basic function module; the twisting module is arranged at one end of the tension and compression module; the test-piece clamping module is arranged on the tension and compression module; the bending module is independently arranged at one side of a portal frame. The micro material mechanical performance testing platform can be taken as a material mechanical performance test device with an independent stretching/compressing mode or an independent bending mode or independent twisting mode, namely a single load testing mode, and can be applied to a material mechanical performance test of a twisting load under the given stretching/compressing stress level or a material mechanical performance test of a bending load under the given stretching/compressing stress level, namely a composite load testing mode. The stress strain process of a material under the effect of a composite load can be detected by the collection of a load/displacement signal by using the detection control module.
