Project ManagementChapter 6Resource Allocation


Resource allocation

Resource Allocation

  • Activities compete with one another and Projects compete with one another for resources

  • Allocate scarce recourses to competing activities in an efficient way.

    • Material

    • Human Resources

    • Capital Resources- i.e. equipment

  • Resource allocation requires trade-offs

    • time constraint

    • resource constraint

    • Performance constraint

Resource loading

Resource Loading

For each resource

For each time period: Determine the total resource time required by all activities

If total Time Required < Capacity Go to 2

Re-schedule some activities to eliminate resource overloading in that time period

Delay activities that have slack time first; No impact on CP

If that doesn’t work, then delay one or more critical activity

Go to 1


Resource loading leveling and uncertainty

Resource Loading/Leveling and Uncertainty

28,282 Hours Needed during the next 34 weeks

Group Capacity

21 (people)  40 (hours/week)  34 weeks = 28,560 labor hours

Correction for Holidays

21 (people)  3 (days)  8 (hours) = 504 labor hours

Vacations

11 (people)  2 (weeks)  40 (hours) = 880 labor hours

Hours Available

28,560 - 504 - 880 = 27,176

about 1100 less than needed

28,282/27176 = 1.04, or 104% of capacity

Allocation priority rules

Allocation Priority Rules

  • As soon as possible: Standard rule in scheduling. Activities are scheduled to start on their ESTs

  • As late as possible: Activities start on their LSTs whenever possible without increasing the project’s duration

  • Shortest task duration first: Consistent with technological precedence's,

  • Minimum slack first: Tasks are supplied with resources in inverse order of their slacks

  • Most critical followers: Activities with a higher number of critical successors take precedence

  • Most successors: Same as previous rule except all successors are counted

  • Most resources first: The greater the use of a specific resource on a task, the higher the task’s priority for the resource

Standards to measure schedule effectiveness

Standards to Measure Schedule Effectiveness

  • Schedule Slippage

    • The difference between actual completion date and the planned date

    • Slippage may cause penalties

    • Expediting one project can cause others to slip

    • Taking on a new project can cause existing projects to slip

  • Resource Utilization

    • The percentage of a resource actually used

    • We prefer balanced utilization among most of the resource types

  • In-Process Inventory

    • The volume of work waiting to be processed because there is a shortage of some resource

    • Similar to WIP in manufacturing

    • The cost here is holding cost of the resources waiting
