What is resource allocation ? What are the methods for resource allocation

I thank you for selecting the “” to get an answer for your Economic query and directing it to me.

Resource allocation is the assignment of available resources to various uses.

• In the context of an entire economy, resources can be allocated by various means, such as markets or central planning.
• In project management, resource allocation or resource management is the scheduling of activities and the resources required by those activities while taking into consideration both the resource availability and the project time
• In strategic planning, resource allocation is a plan for using available resources, for example human resources, especially in the near term, to achieve goals for the future. It is the process of allocating scarce resources among the various projects or business units.
• There are a number of approaches to solving resource allocation problems e.g. resources can be allocated using a manual approach, an algorithmic approach (logical method) or a combination of both.
• There may be contingency mechanisms such as a priority ranking of items excluded from the plan, showing which items to fund if more resources should become available and a priority ranking of some items included in the plan, showing which items should be sacrificed if total funding must be reduced.

Resource allocation methods.

Important First

• In important first resource allocation, the resource is allocated priority work resource request. The list of free resources are maintained as a stack. An allocation request is serviced by from the stack. When a job is over, it is allotted to next priority work.
• The disadvantage of this scheme is that there will be uneven utilization of resources. If the resource allocation leads to wear and tear, the frequently allocated resources will experience lesser utility. This scheme would be primarily used in allocating a resource involving considerable setup time before use.

Unused First

In this method, first resource allocation will be the resource not allocated for maximum time. To implement, the resource allocating entity keeps the free resources in a queue. A resource allocation request is serviced by removing a resource from the head of the queue. A freed resource is returned to the free list by adding it to the tail of the queue.
The main advantage of this scheme is that there is even utilization of resources. Also, freed resource does not get reused for quite a while, so inconsistencies in resource management can be easily resolved via reviews.

Load Balancing

In situations involving multiple resource groups, load balancing is used. A resource group is controlled by a local resource controller. In this technique, the resource allocator first determines the lightly loaded resource group. Then, the resource controller of the lightly loaded  resource  group performs the actual resource allocation. The main objective of resource allocations is to distribute the load evenly amongst resource controllers.

Future Resource Booking

Here, each resource allocation is for a specified time. The resource allocation is only valid till the specified time is reached. When the specified time is reached, the resource is considered to be free. Thus the resource does not need to be freed by the user. (This is actually quite similar to an advanced booking in a train travel)
This technique is used where a particular resource needs to be allocated for short duration. When an allocation request is received, the booking status of the resource is searched to find the earliest time in future when the resource request can be serviced. Resource booking tables are updated with the start and end time of each resource allocation.
