has been developed for quick reference the operator wishing to use the system would therefore proceed as follows determine the estimated cost of the project refer to the chart of fig4 and obtain a corresponding period of completion select the overlay e g fig2 etc divided into uniform intervals for the period and placed over the normalized chart of fig1 to determine the scheduling of events it should be understood that the particular embodiment is illustrative only and other divisions and statistical indicia may be used according to the first embodiment of the present invention there has therefor been provided a system for allocating different phases of a contractual obligation with each of a plurality of phases of the contract statistically allocated over a normalized period and conversion of that normalized period to a real time interval in accordance with a criteria established which has proven reliable in the particular instance the estimated costs of the job would provide a reasonable approximation of the actual time and man hour requirements to perform the particular job in fig5 there is illustrated a manpower allocation tool which may be used in conjunction with or independently of the scheduling tool previously described when used together they form a basis for not only scheduling a particular job over the individual contract period but also scheduling other jobs or phases thereof which overlap with existing obligations or those contemplated in the near future during a project in fig5 there is shown one element of the scheduling tool with a base 20 a slot 21 and bores 22 evenly disposed along.
