INTRODUCTION- Definition of Resource

• A resource is a source or supply from which benefit is produced; materials or other assets that are transformed to produce benefit and in the process may be consumed or made unavailable.

• The first step in resource scheduling is to decide exactly what resources are considered important enough to be scheduled.

• Resources may be considered as consumable, such as materials that may be used once and once only, or non-consumable, such as people, which may be used again and again.

Scheduling

A Resource Schedule, is a timetable of events and resources. The schedule maintains separation between users of the resources. The process of creating a schedule is called scheduling.

A Resource Schedule is often maintained by a manager.

In a company’s resource management, effective and well-organized resource scheduling is a must.

This task of scheduling guarantees a proficient handling of employee skills.

Time-Limited Resource Scheduling

Time-limited resource smoothing is used when the end date of Project cannot be exceeded.

The project has heavy time penalties.

The project has another critical access dates.

Resource overloads are addressed by increasing resources.

Resource-Limited Resource Scheduling

Resource-Limited Resource Scheduling can be done when resource limit cannot be exceeded.

If there are resource overloads planned activities will have to be delayed; end date can be extended.

Confined space, limited availabilities,equipment limitations, safety requirements can cause this type of situation.

Resource Availability


ESTIMATING SCHEDULE ACTIVITY RESOURCE REQUIREMENTS

• DETERMINING WHAT RESOURCES WILL BE REQUIRED (LABOR, EQUIPMENT, MATERIAL)

• WHAT QUANTITY FOR EACH RESOURCE WILL BE REQUIRED.

• WHEN ARE RESOURCES AVAILABLE TO PERFORM PROJECT ACTIVITIES


An ACTIVITY is any work that has a beginning and an end. And requires the use of Project resources including people, time and money

Resources for each project Activity helps to create a Project Plan

Resources availability enables to assign TIME ESTIMATES to each Activity

Resource productivity defined in volume units per hour then activity duration may be calculated during project

• CONCERNED WITH ASSIGNING REQUIRED NUMBER OF RESOURCES.

• MORE THAN ONE TYPE OF RESOURCE MAY BE ATTRIBUTED TO A SPECIFIC ACTIVITY.

PROBLEMS ASSOCIATED• DO NOT ADDRESS THE ISSUE OF RESOURCE

UTILIZATION AND AVAILABILITY.

• FOCUS IS ON TIME RATHER THAN PHYSICAL RESOURCES.

• IMPACT OF RESOURCE ALLOCATION DECISION IS NOT KNOWN.

RESOURCE ALLOCATION

Summation of resources, required to complete all activities.

Results are shown graphically as a histogram.

Done on hourly, weekly, monthly basis.

RESOURCE LEVELING

Process that ensures resource demand does not exceed resource availability

Resource leveling is used:-

to address schedule activities that need to be performed to meet

specified delivery dates.

to address a situation where shared or critical required resources are

only available at certain times or are only available in limited quantities.

to keep selected resource usage at a constant level during specific time

periods of the project work.


UNIVERSITY

RESOURCE Smoothing

Process of moving activities to improve the resource loading profile.

First step is to select the resource to be smoothed, because it is not possible

to smooth for more than one resource at a time.

To decide which resource to smooth consider:

The resource that is most overloaded.

The resource that is most used on the project.

The least flexible resource - this could be the resource that comes from overseas,

is difficult to get hold of or is least available.

The most expensive resource to hire.


UNIVERSITY

Two approaches to leveling and smoothing the resources

Time-limited resource considerations

completing the project within a specified time

Resource-limited resource considerations

project must be completed with the resources available even if this

means extending the project duration

CASE STUDY : IDAHO POWER COMPANY

( Resource Planning & Procurement Strategy - following the California energy crisis.)

THE COMPANY:Idaho Power Company (IPC) is a 3,000 MW traditional investor-owned utilityserving 426,600 customers in southern Idaho and eastern Oregon. The Company’s generation mix is about 60% hydro, 30% thermal, and 10% purchased power – in an average year.

Traditional Market Approach :Supply based on buying or selling power in wholesale markets to balance system load.

Resource components include :Fuelpurchased power cogeneration small power production less surplus sales to customers

THE CRISIS:

• Prices in western energy markets inflated to unprecedented levels.• The Company’s purchased power costs escalated rapidly• Deferred recovery of a pending $59 million

REGULATORY MODELS:

Following seven years of drought, the Company implemented a power cost adjustment (PCA) mechanism to track power supply costs.

On an interim basis the Company has defined market risk as the exposure to adverse movements in regional power prices in conjunction with adverse hydro conditions.

The Company has identified the major factors driving variations in purchased power cost, and each year establishes risk guidelines that serve to limit the Company’s market risk over a maximum 18-month period.



OPERATIONAL APPROACH :Collaborative workshops with staff and customer representatives (via a Customer Advisory Group - CAG) to review the resource-related risks facing the Company and its customers. Market Review Trigger - strategy includes agreed-upon risk tolerances, and an early-warning mechanism SIGNIFICANCE OF APPROACH : To provide a forum for input to confirm consensus Provide an opportunity for members to review the Company’s implementation. They encourage discussion on enhancing/modifying the Company’s resource scheduling strategy.

SUCCESS STORY :96-97% of eligible procured power costs ($500 million) have been recovered.Regarding the use of financial resources, new skill sets have been acquired, including the use of new software tools to quantify market risk.Physical generating capacity, rate design, and load control became the most feasible alternatives for managing resources.
