Method and system for workforce related resource planning

1. A method for workforce related resource planning, comprising:

receiving, by a computer system, workforce related resource data associated with a planning horizon having a plurality of time periods, wherein the workforce related resource data includes demand data and supply data; and

creating, by the computer system, a probability distribution of a workforce gap between the demand data and the supply data for each of the time periods to quantify risks associated with the workforce related resource planning, wherein the probability distribution of the workforce gap is based on a probability distribution of demand calculated from:

a probability distribution of workforce requirements during a given period based on probabilities of workforce required by corresponding project opportunities and probabilities of winning the corresponding project opportunities; and

a probability distribution of workforce replacement requirements based on a distribution of workforce assigned to projects and a probability of attrition of workforce assigned to the projects.

receiving a target level of service;

determining, by a computer system, a workforce related resource requirement for the target level of service; and

providing, by the computer system, a probability distribution of achieving the target level of service based on the workforce related resource requirement, the probability distribution being based on a probability distribution of demand calculated from:

a probability distribution of workforce requirements during a given period based on probabilities of workforce required by corresponding project opportunities and probabilities of winning the corresponding project opportunities; and

a probability distribution of workforce replacement requirements based on a distribution of workforce assigned to projects and a probability of attrition of workforce assigned to the projects.

10. The method of claim 9 , wherein the workforce related resource requirement is based on demand data and supply data.

11. The method of claim 10 , wherein determining the workforce related resource requirement for the target level of service comprises:

disaggregating the demand data and the supply data based on skill and time period.

12. The method of claim 10 , wherein providing the probability distribution of achieving the target level of service based on the workforce related resource requirement comprises:

computing a probability distribution of supply for the given period; and

computing the probability distribution of a workforce gap that is based on a difference between the probability distribution of demand for the given period and the probability distribution of supply for the given period, wherein the probability distribution of the workforce gap includes probabilities that a variable will have corresponding different values in the given period.

13. The method of claim 12 , further comprising:

calculating a number of job offers to extend in order to satisfy the target level of service based on the probability distribution of the workforce gap.

14. A non-transitory computer-readable storage medium for workforce related resource planning, the computer-readable medium having instructions stored thereon which, when executed, cause a computer to:

receive workforce related resource data associated with a planning horizon having a plurality of time periods, wherein the workforce related resource data includes demand data and supply data; and

create a probability distribution of a workforce gap between the demand data and supply data for each of the time periods to quantify risks associated with the workforce related resource planning, wherein the probability distribution of the workforce gap is based on a probability distribution of demand calculated from:

a probability distribution of workforce requirements during a given period based on probabilities of workforce required by corresponding project opportunities and probabilities of winning the corresponding project opportunities; and

a probability distribution of workforce replacement requirements based on a distribution of workforce assigned to projects and a probability of attrition of workforce assigned to the projects.
