Types of project constraints

Scheduling Problem

Resource allocation Methods

Splitting Activities

Benefits of Scheduling Resources

Multi-project Resource Schedule

Rationale for Reducing Project Duration

Accelarating Project Completion

Cost

Priority Rules

Technical or Logic Constraints

Resource Constraints

related to the networked sequence in which project activities must occur

absence, shortage, or unique interrelationship and interaction characteristics of resources that require a particular sequencing of project activities

People, Materials, Equipment, Working Capital

Time Constrained Project

Resource Constrained Project

Limiting Assumptions

Time-Constrained Projects

Disadvantages

Splitting activities is not allowed

Level of resource cannot be changed

most slack pose the least risk.

Reduction of flexibility does not increase risk.

completed by an imposed date

leveling techniques

Peak resource demands are reduced

Resources over the life of the project are reduced.

Fluctuation in resource demand is minimized.

Loss of flexibility occurs from reducing slack

Increase in criticality of all activities

Scheduling technique to get a better project schedule or to increase resource utilization

Leaves time for consideration of reasonable alternatives :

Provides information for timephased work package budgets to assess:

Cost-time tradeoffs Changes in priorities

Impact of unforeseen events.

Amount of flexibility in available resources

Problem

Solution

Overall project Slippage

Inefficient resource application

Resource bottlenecks

Create Project Offices or departments

Use a project priority queuing system

Centralized project management

Outsource

Time to Market

Adaptability

Unforeseen Delays

Incentive Contracts

Imposed Deadlines

Resource Constraints

Resource Not Constraints

Do it twice – fast and correctly

Fast-tracking

Critical chain

Reducing Project Scope

Compromise Quality

Adding resources

Outsourcing Project Work

Scheduling Overtime (OT)

Establish a Core Project Team

Advantages

Disadvantages

Avoid additional cost

Fewer distraction

2x / 3x payment

productivity decline

Direct Cost

Indirect Cost

Normal costs that can be assigned directly to a specific work package/project activity

Labor, materials, equipments, and subcontractors

Crashing will increase direct costs

Cannot be associated with any particular work package

Supervision, admin, consultant, machinery

(crashing) will reduce indirect costs.

ASAP

Minimum Slack First

ALAP

Shortest task duration first

Most Successor

Most critical followers

Most Resource first
