A method of forming a single-cell column type of multi-cellular collapsible window covering from a starting product in the form of a double-cell column type of multi-cellular honeycomb structure. The present method also comprises plotting the respective capacitance values as a quasi-linear function of the respective predetermined widths, extrapolating a calibration term from the quasi-linear function, and subtracting the calibration term from the respective predetermined widths to define and constrain the active region width for facilitating device fabrication. The resource information representing a plurality of resources available for allocation to the projects, and each project definition includes a unique identifier and one or more project-level constraints.
