CONSTRUCTION PLAN PREPARATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a construction plan preparation method by which an optimum construction plan is prepared for the handling physical amount of distributed work sites. SOLUTION: In the case of applying this method to the tollgate building construction of an expressway, respectively intrinsic work numbers are attached to construction works to be executed at respective tollgates and data regarding work occupation types engaged in the work of the work number and the data regarding the number of workers are related. Respectively intrinsic construction plane candidate numbers are attached to construction plans composed of a number string for which the work numbers are cited in the order of work schedules and construction plan candidate data are constructed. Construction plan candidates are extracted on the basis of the construction plan candidate data of the respective tollgates and the combination of the construction plan candidates is expressed by a character string. For the character string, construction period shortening and a resource leveling degree (the leveling of the maximum number of the workers required per day) are taken into consideration and the character string is functionally optimized by utilizing a genetic algorithm.
