Project Planning And Management-Btechnd

Introduction

Resource scheduling refers to a collection of techniques that are used for calculating the resources necessary for delivering the work and the time required for the delivery of the project (Larson and Gray, 2010, p.89). In the given case study, the individual has received a phone call from partner, Benson, who is in desperate need of the injection molding machine. The individual’s response to Benson’s request is dependent on the fact that the individual would be able to complete the work within 10 months, with the use of only 2 machines. Therefore, in the following study, a resource schedule and loading chart has been prepared, in order to determine what should be the individual’s response to Benson’s request.

  1. Resource schedule and loading chart of the project in 10 months using only 2 machines

The network diagram in the given case study is as follows:

Resource constrained schedule:

Based on the above network diagram, the resource constrained schedule can be plotted as follows:

Explanation of the schedule:

PeriodAction
0-1Activities 1 and 2 are feasible, because the sum of resources is 2, which is equal to the total number of resources available. Hence, both activities are put into the schedule.
1-2Activities 2 and 3 are eligible, because activity 2 is already in action, and activity 1 is completed. Activity 3 is also undertaken, because the resources used is equal to the total number of resources available. Thus, SL(1) = 4, ES(1) = 0. Since one resource is still available as activity 1 has been completed, LF(1) = 5 >= 2, which is the total number of resources available. Therefore, this period can be included in the slack of activity 1.
2-3 Activities 2 and 3 are eligible, because activity 2 has already started and, activity 1 has been completed. Since, activity 2 has been loaded into the resource constrained schedule, Activity 3 is also loaded, as the total number of resources used is 2, which is equal to the total number of resources available.  Thus, SL(1) = 4, ES(1) = 0. LF(1) = 5 >=2, which is more than the total number of resources available. Therefore, this period can be included in the slack of activity 2.
3-4Activities 3 and 4 are eligible, because activities 1 and 2 are completed. Since the slack of activity 3 is the lowest, that is, SL(3) = 0, activity 4 is loaded into the resource constrained schedule. Thus, SL(4) = 3, ES(4) = 2. Therefore, this period can be included in the slack of activity 3.
4-5Activities 3 and 4 are eligible. Since the slack of activity 3 is the lowest, activity 4 is loaded into the resource constrained schedule. Thus, SL(4) = 3, ES(4) = 2. Therefore, this period can be included in the slack of activity 3.
5-6Activities 3 and 4 are eligible in this period. The sum of the resources used is equal to 2, which is equal to the total number of resources available.
6-7Activities 4 and 5 are not eligible, even though activity 3 is complete. Activity 4 is loaded into the resource constrained schedule. Thus, SL(4) = 3, ES(4) = 2. Therefore, this period can be included in the slack of activity 4.
7-8Activities 5 and 6 are not eligible, even though activity 4 is complete, because the total number of resources available is 2. Therefore, this period cannot be included in the slack of activity 4.
8-9Activities 5 and 6 are not eligible, even though activity 4 is complete, because the total number of resources available is 2. Therefore, only activity 5 can be loaded in the schedule.
9-10Activities 5 and 6 are not eligible. Therefore, only activity 5 can be loaded in the schedule (Davidson,2014, p80).
10-11Only activity 5 can be loaded in the resource constrained schedule.
11-12Activity 6 is feasible as activity 5 is complete. Moreover, the number of resources used is 2, which is equal to the total number of resources available.
12-13Activity 6 is completed, because of the availability of resources.

Assumption:

While making the resource schedule and loading chart of the project, it is assumed that both the injection moulding machines of the individual are in working condition (Rose, 2015, p.65).

  1. Reply to Benson’s request

As per the case study, the individual would lend the injection moulding machine only if it is possible to complete the project within 10 months. However, according to the resource constrained schedule plotted above, it can be seen that the project would take 12 months to complete. In other words, the individual would be unable to complete the project using only 2 injection moulding machines within 10 months. Therefore, the individual must not say yes to Benson’s request.
Conclusion
From the above study it can be concluded that the individual can estimate whether completion of the project within 10 months period, using only 2 injection moulding machines is not possible. Hence, the individual must decline partner Benson’s request.
