Estimate Based On Work Plan

This type of analysis provides the user the ability to determine the network condition if there is already a provisional work plan for the analysis period. The analysis employs deterioration and improvement in the same manner as all other analysis types. The result of this analysis is to show the resultant condition of the network in future years if only the MWP is employed.

This type of analysis is not to recommend treatment strategies to maintain the network at certain target levels, but only to project the conditions under the selected master work plans. Therefore, there is no requirement for an objective function or constraints to force restrictions on the decision variable. As part of the analysis, the optimization engine takes into consideration the existing work plan and the current network condition. In the following step, the current conditions are updated to reflect the influence of the work plan, carried forward to the following year, and the whole process is reiterated for subsequent years included in the analysis period. The analysis ends with estimates for the network condition and maintenance expenditures, which may be post-processed to generate suitable reports that present the information in a concise format. As in the case of “strategy with work plan”, the user may decide to limit the scope of the analysis to certain routes or functional classes or even restrict the extent of the work plan that is included in the analysis to keep the problem manageable.
