Patent application number	Description	Published
20120041797	PROGRESS MONITORING METHOD - The progress monitoring method is based on a critical path method (CPM) and conducts comparisons against multiple possible outcomes utilizing neural networks that classify planned progress at specified cut-off dates during a planning stage. The classifications are used to monitor and evaluate actual progress during the construction stage. The pattern recognition techniques generalize a virtual benchmark to represent planned progress based on multiple possible outcomes generated at each cut-off date. The generalization feature overcomes the problem of variation in the quality of data collected. Patterns are constructed to encode planned and actual progress at different cut-off dates. Patterns are readily manipulated within computer programs and substitute for photographs, which are not comprehensive in representing the work status of interior and hidden parts of the under-construction facilities.	02-16-2012

20110060624	Design and process scheduling optimization method - The design and process scheduling optimization method is a technique that circumvents problems encountered in previous optimization techniques. The method performs comparison against multiple possible outcomes rather than a single-valued benchmark. Pattern Recognition (PR) techniques are utilized to classify the work planned at specified cut-off dates during the planning stage. Classification is used to monitor and evaluate the progress during the construction stage. The PR technique generalizes a virtual benchmark to represent the whole project based on multiple possible outcomes generated at a given cut-off date. The generalization feature offers a potential tool to overcome the problem of variation in the quality of data collected. Patterns are constructed to encode work of the project at different cut-off dates. The present invention utilizes a robust pattern recognition method applied to Critical Path Method (CPM) procedures to monitor and evaluate progress of construction projects.	03-10-2011

20110082821	Method of generating precedence-preserving crossover and mutation operations in genetic algorithms - A method for generating precedence-preserving crossover and mutations operations for genetic algorithms is provided. The method is based on the determination of activities' Forward Free Float (FFF) and Backward Free Float (BFF) values, utilizing these float values in randomly selected forward and backward paths, respectively. The method may be applied to the finance-based scheduling domain using large scale projects, with the chromosomes of the genetic algorithm encoding activities' start times in a resource-constrained scheduling problem.	04-07-2011

20120029959	METHOD OF EXTENDING ACTIVITY FLOATS IN THE CRITICAL PATH METHOD - The method of extending floats in the critical path method (CPM) method allows for extending the project duration while keeping the networking basic parameter of total float intact. The method allows for rescheduling of the start times of some activities so that the resource requirements never exceed the specified resource limit. The extendable network transforms the process of seeking an extended schedule that fulfils resource constraints from searching in a boundless solution space to searching in a well-defined and definite solution space. The definite searching space harnesses for the mathematical formulation of the optimization techniques, i.e., integer programming, which provides the optimum solution as a schedule that fulfills the resource constraint and yet minimizes the project duration.	02-02-2012
