Interpretation: A process flow diagram is to be constructed along withlabeling and the times and percentages.

(a)

Explanation of Solution
Process flow diagram is as follows.
(b)
Interpretation: The throughout in patients is to be determined per hour of each stage in the process.
Concept Introduction:
The throughput of any process is the rate at which outputs are coming out of the process. When the capacity (i.e. the service rate) of a process step is more than or equal to the arrival rate or the demand rate, the throughput will be equal to the demand rate.
On the contrary, if the capacity is less than the demand rate, it means that the process step is a bottleneck and the throughput will be equal to the capacity.
(b)

Explanation of Solution
The throughout in patients per hour of each stage in the process is shown in table below.
Resource | Demand or arrival rate | Capacity or Service rate | Condition | Throughout rate |
RC | 10 per hour | 10 per hour | ||
RRC | 10 per hour | 10 per hour | ||
NP | 10 per hour | 10 per hour | ||
PA | 4 per hour | |||
MD | 4 per hour | |||
BC | 8 per hour | 8 per hour |
(c)
Interpretation: The labor utilization rates are to be calculated and whether these values appropriate. In case they are not appropriate the way the process can be redesigned is to be determined along with then bottlenecks.
Concept Introduction:
The labor utilization is defined as the fraction of time a resource is busy producing output in the long run. It can be calculated by using the following formula.
(c)

Explanation of Solution
However, note that the labor utilization cannot be more than 100% in long run. However, in short run, we can write it as more than 100% using the above formula.
Resource | Demand or arrival rate | Capacity or Service rate | Number of servers (N) | Utilization (U) |
RC | 10 per hour | 1 | 50.00% | |
RRC | 10 per hour | 1 | 100.00% | |
NP | 10 per hour | 1 | 83.33% | |
PA | 1 | 40.00% | ||
MD | 1 | 150.00% | ||
BC | 8 per hour | 1 | 66.67% |
The resource RRC and MD are overloaded as the utilization figures suggest. Similarly, the resource RC and PA are under loaded. Possible improvement strategy is to share the loads of work (as they are similar in nature) between RC and RRC. Also, it should be checked whether the 60/40 ratio of diversion to MD and PA can be modified in order to balance their load
At present, the resource MD, having the capacity less than the arrival rate and thus the flow is constrained at MD. So, it is the bottleneck.
(d)
Interpretation: The way by which the given change affect your answer to the preceding questions.
Concept Introduction:
Any flow unit, when flows through a process, follows L’s Law which states that the Work in Progress and given by,
(d)

Explanation of Solution
Due to the change, the process layout will be as follows.
The throughput rates for each resource will be as follows.
Resource | Demand or arrival rate (D) | Capacity or Service rate | Condition | Throughout rate |
RC | 10 per hour | 10 per hour | ||
RRC | 10 per hour | 10 per hour | ||
NP | 10 per hour | 10 per hour | ||
PA | 4 per hour | |||
MD | 4 per hour | |||
BC | 6 per hour |
The labor utilization of the resources are as follows.
Resource | Demand or arrival rate | Capacity or Service rate | Number of servers (N) | Utilization (U)
|
RC | 10 per hour | 1 | 50.00% | |
RRC | 10 per hour | 1 | 100.00% | |
NP | 10 per hour | 1 | 83.33% | |
PA | 1 | 40.00% | ||
MD | 1 | 200.00% | ||
BC | 1 | 50.00% |
Note that the utilization of MD has just jumped to 200%.
