Abstract: Effective and efficient multi-vendor labor rate negotiations are supported by using a minimization algorithm to provide an optimized total cost of staffing allocation. Critical impact factors are also provided to identify specific labor categories or other vendor attributes that have the greatest impact on the total staffing allocation cost. By varying the elements identified by the critical impact factors and using the computer-implemented optimization algorithm, real-time changes are available to the vendors to assist in the negotiations of services contract agreements.
