SYSTEMS, METHODS AND APPARATUS FOR PROVIDING COMPARATIVE STATISTICAL INFORMATION FOR A PLURALITY OF PRODUCTION FACILITIES IN A CLOSED-LOOP PRODUCTION MANAGEMENT SYSTEM

摘要

For each of a plurality of production facilities, a series of operations is performed. For each of a plurality of batches of a concrete mixture produced at the respective production facility based on a formulation, a first difference between a measured quantity of cementitious and a first quantity specified in the formulation is determined. A first standard deviation is determined based on the first differences. For each of the plurality of batches, a second difference between a measured quantity of water and a second quantity specified in the formulation is determined. A second standard deviation is determined based on the second differences. A first benchmark is selected from among the first standard deviations, and a second benchmark is selected from among the second standard deviations. An amount by which costs may be reduced by improving production at the production facility to meet the first and second benchmarks is determined.

主权项

1. A quality control management system comprising:
a database module having stored therein a formulation, a first tolerance and a second tolerance, the first tolerance associated with an first alert and the second tolerance associated with an second alert; an input module in communication with the database module and configured to transmit the formulation, the first tolerance and the second tolerance to the database module; a production module in communication with the database module, the production module associated with a production facility that makes a mixture based on the formulation and configured to communicate the mixture to the database module; a comparison module in communication with the database module, and configured to:
compare the mixture to the formulation and determine whether the mixture is within the first tolerance and determine whether the mixture is within the second tolerance; and an alerts module configured to generate the first alert if the mixture is not within the first tolerance and generate the second alert if the mixture is not within the second tolerance.
